This commit upgrades ingress-nginx to version v1.12.1, addressing multiple critical vulnerabilities including CVE-2025-1974, CVE-2025-1097, CVE-2025-1098, CVE-2025-24513, and CVE-2025-24514 as detailed in the ingress-nginx release notes: https://github.com/kubernetes/ingress-nginx/releases/tag/controller-v1.12.1
Important Notes:
- Fixing CVE-2025-1974 required disabling validation of the generated NGINX configuration during validation of Ingress resources. Invalid Ingress resources may stop the NGINX configuration from being updated.
- Recommended mitigations include enabling annotation validation and disabling snippet annotations.
Alongside this upgrade, the `ingress_nginx_kube_webhook_certgen_image_tag` has been updated to v1.5.2 for compatibility, based on: https://github.com/kubernetes/ingress-nginx/pull/13066
Changelog:
- Updated ingress-nginx version to v1.12.1 in Kubespray.
- Updated `ingress_nginx_kube_webhook_certgen_image_tag` in `roles/kubespray-defaults/defaults/main/download.yml` to v1.5.2.
Fixes: https://github.com/kubernetes-sigs/kubespray/issues/12073
* Refactor control plane upgrades with reconfiguration support
Adds revised support for:
- The previously removed `--config` argument for `kubeadm upgrade apply`
- Changes to `ClusterConfiguration` as part of the `upgrade-cluster.yml` playbook lifecycle
- kubeadm-config `v1beta4` `UpgradeConfiguration` for the `kubeadm upgrade apply` command: [UpgradeConfiguration v1beta4](https://kubernetes.io/docs/reference/config-api/kubeadm-config.v1beta4/#kubeadm-k8s-io-v1beta4-UpgradeConfiguration).
* Add kubeadm upgrade node support
Per discussion:
- Use `kubeadm upgrade node` on secondary control plane upgrades
- Add support for UpgradeConfiguration.node in kubeadm-config.v1beta4
- Remove redundant `allowRCUpgrades` config
- Revert from `block` for first and secondary control plane back to unblocked tasks since they no longer share much code and it's more readable this way
* Add kubelet and kube-proxy reconfiguration to upgrades
* Fix task to use `kubeadm init phase etcd local`
* Rebase with changes from "Adapt checksums and versions to new hashes updater" PR
* Add `imagePullPolicy` and `imagePullSerial` to kubeadm-config v1beta4 `InitConfiguration.nodeRegistration`
* Ensure correct `AuthorizationConfiguration` API version during upgrades
Fixes an issue where the wrong AuthorizationConfiguration API version could be used by kube-apiserver prematurely during upgrades.
The `kubernets/control-plane` role writes configuration for the target version before control plane pods are upgraded.
However, since the `AuthorizationConfiguration` file is reconciled continuously, this leads to a race condition where a new configuration version can be reconciled before kube-apiserver is upgraded to the compatible version.
This solution ensures the correct configuration is available throughout the process by writing each api version to a different file path. Unused file versions are cleaned up post-upgrade for better hygiene.
* Avoid from_json in cleanup task
The versions which are by default derived from `kube_version` can break
the assert if kube_version start with `v`, because they use the start of
`kube_version` as dict key.
By putting them in their own assert, the first assert should trigger on
`kube_version`, with a more explicit error.

* Upcloud: Added support for routers and gateways
* Upcloud: Added ipsec properties for UpCloud gateway VPN
* Upcloud: Added support for deprecated network field for loadbalancers
There is litte reason to share an ssh key common to all CI jobs, so
generate one for each on the fly.
Also use plain-text cloud-init config instead of base64 for readability
To work with molecule, we need to use the name provided by molecule_yml
in inventory.
Inject the name in the VirtualMachineInstance (with a default to handle
non-molecule scenario) and get it back as part of inventory).
Account for no ansible groups
The current templating of kubevirt VirtualMachine relies on global
ansible variables, except for the group the nodes are meant to be in.
In order to have more flexibility (in particular, mixed OS cluster for
instances), expect now an abitrary dict to be passed to the template ;
this allows to embed directly in the nodes definition any variable used
by the template.
The script is obsoleted by 5d7236ea5 (Merge pull request #11890 from
VannTen/download_graphql_checksums_2, 2025-03-09), since the format of
checksums is no longer compatible.
Allow the use of different hashes, as support by the get_url
Ansible module.
Change the variable name accordingly to 'checksum' since it's not
exclusively sha256 anymore.
The versions are nearly all .0 because of the gvisor release scheme.
This means they need to be quoted in yaml to be considered strings.
Special casing by removing the .0 make tooling more complicated, and it
does not gain us anything apart from a nicer looking file (I guess).
So just use the version of upstream gvisor and quote it.
* CI: Put pre-commit cache under CI_PROJECT_DIR
Apparently gitlab-runner can't cache stuff outside of the project
directory.
Put the cache under CI_PROJECT_DIR to make it work (which also means we
need to ignore it from ansible-lint).
Also update the pre-commit image while we're at it.
Link: https://gitlab.com/gitlab-org/gitlab/-/issues/14151
* update ansible-lint pre-commit
This adds a new flag with default `kubeadm_config_validate_enabled: true` to use when debugging features and enhancements affected by the `kubeadm config validate command`.
This new flag should be set to `false` only for development and testing scenarios where validation is expected to fail (pre-release Kubernetes versions, etc).
While working with development and test versions of Kubernetes and Kubespray, I found this option very useful.
* Automatically derive defaults versions from checksums
Currently, when updating checksums, we manually update the default
versions.
However, AFAICT, for all components where we have checksums, we're using
the newest version out of those checksums.
Codify this in the `_version` defaults variables definition to make the
process automatic and reduce manual steps (as well as the diff size
during reviews).
We assume the versions are sorted, with newest first. This should be
guaranteed by the pre-commit hooks.
* Validate checksums are ordered by versions, newest first
* Generalize render-readme-versions hook for other static files
The pre-commit hook introduced a142f40e2 (Update versions in README.md
with pre-commit, 2025-01-21) allow to update our README with new
versions.
It turns out other "static" files (== which don't interpret Ansible
variables) also use the default version (in that case, our Dockefiles,
but there might be others)
The Dockerfile breaks if the variable they use (`kube_version`) is a
Jinja template.
For helping with automatic version upgrade, generalize the hook to deal
with other static files, and make a template out of the Dockerfile.
* Dockerfile: template kube_version with pre-commit instead of runtime
* Validate all versions/checksums are strings in pre-commit
All the ansible/python tooling for version is for version strings. YAML
unhelpfully consider some stuff as number, so enforce this.
* Stringify checksums versions
* exclude .ansible in ansible-lint
* remote ctr i pull workdaround

The build steps at the start of CI takes about 2 minutes; now that we
have greatly reduced the overall duration, this is not an insignificant
impact.
Add timestamps to the build process to see measure which steps of the
image build take the most time.
* Remove krew installation support
Krew is fundamentally to install kubectl plugins, which are eminently a
client side things.
It's also not difficult to install on a client machine.
* Remove krew cleanup
This has been deprecated for a long time, time to pull the plug.
We leave an assert for one release to have a straightforward failure if
some users were still using the variable.
Since 'none' can be, for instance, a manual calico deployment, don't
check whether there is enough ip for pods on a node, because the plugin
can use another mechanism than the podCIDR to allocate IPs.
When the etcd group is not specified we assume it's kube_control_plane.
In that case, etcd still can't be even, so instead of only checking the
etcd group we need to default to kube_control_plane
ansible-lint and yamllint are run as pre-commit hooks, which are
installed by pre-commit directly. So there is no need to put them in
tests/requirements.txt.
So remove them and make it leaner.
Upstream calico isn't doing that, and:
- this can cause throttling
- the cpu needed by calico is very cluster / workload dependent
- missing cpu limits will not starve other pods (unlike missing memory
requests), because the kernel scheduler will still gives priority to
other process in pods not exceeding their requests
Currently, versions in README.md need to be manually updated, and we
check it's done with a bash script.
Add a small utility playbook to add versions in README.md from their
actual default values, automatically.
This is done in pre-commit, and replace the scripted check ; instead it
will autofix the README.md, and fails in CI if needed.
We switch markdownlint behind the local hooks to gave it the opportunity
to catch a problem with the rendering.
Since e8ee42280 (CI: remove deletion tasks of 'packet' VMs, 2024-09-13),
our tests appears to not be flakey anymore.
The current retry slow down the testing feedback on pull request.
Since it's not needed anymore, don't retry and fail fast.
This is handy when some component releases is buggy (missing file at the
download links) to not block everything else.
Move the filtering up the stack so we don't have to do it multiples
times.
Gvisor releases, besides only being tags, have some particularities:
- they are of the form yyyymmdd.p -> this get interpreted as a yaml
float, so we need to explicitely convert to string to make it work.
- there is no semver-like attached to the version numbers, but the API
(= OCI container runtime interface) is expected to be stable (see
linked discussion)
- some older tags don't have hashs for some archs
Link: https://groups.google.com/g/gvisor-users/c/SxMeHt0Yb6Y/m/Xtv7seULCAAJ
Gvisor is the only one of our deployed components which use tags instead
of proper releases. So the tags scraping support will, for now, cater to
gvisor particularities, notably in the tag name format and the fact that
some older releases don't have the same URL scheme.
Containerd use the same repository for releases of it's gRPC API (which
we are not interested in).
Conveniently, those releases have tags which are not valid version
number (being prefixed with 'api/').
This could also be potentially useful for similar cases.
The risk of missing releases because of this are low, since it would
require that a project issue a new release with an invalid format, then
switch back to the previous format (or we miss the fact it's not
updating for a long period of time).
The Github graphQL API needs IDs for querying a variable array of
repository.
Use a dict for components instead of an array of url and record the
corresponding node ID for each component (there are duplicates because
some binaries are provided by the same project/repository).
Adds the ability to configure the Kubernetes API server with a structured authorization configuration file.
Structured AuthorizationConfiguration is a new feature in Kubernetes v1.29+ (GA in v1.32) that configures the API server's authorization modes with a structured configuration file.
AuthorizationConfiguration files offer features not available with the `--authorization-mode` flag, although Kubespray supports both methods and authorization-mode remains the default for now.
Note: Because the `--authorization-config` and `--authorization-mode` flags are mutually exclusive, the `authorization_modes` ansible variable is ignored when `kube_apiserver_use_authorization_config_file` is set to true. The two features cannot be used at the same time.
Docs: https://kubernetes.io/docs/reference/access-authn-authz/authorization/#configuring-the-api-server-using-an-authorization-config-file
Blog + Examples: https://kubernetes.io/blog/2024/04/26/multi-webhook-and-modular-authorization-made-much-easier/
KEP: https://github.com/kubernetes/enhancements/tree/master/keps/sig-auth/3221-structured-authorization-configuration
I tested this all the way back to k8s v1.29 when AuthorizationConfiguration was first introduced as an alpha feature, although v1.29 required some additional workarounds with `kubeadm_patches`, which I included in example comments.
I also included some example comments with CEL expressions that allowed me to configure webhook authorizers without hitting kubeadm 1.29+ issues that block cluster creation and upgrades such as this one: https://github.com/kubernetes/cloud-provider-openstack/issues/2575.
My workaround configures the webhook to ignore requests from kubeadm and system components, which prevents fatal errors from webhooks that are not available yet, and should be authorized by Node or RBAC anyway.
This avoids spurious failure with 'localhost'.
It should also be more correct the inventory contains uncached hosts
which are not in `k8s_cluster` and therefore should not be Kubespray
business.
(We still use hostvars for uncached hosts, because it's easier to select
on 'ansible_default_ipv4' that way and does not change the end result)
We use a lot of facts where variables are enough, and format too early,
which prevent reusing the variables in different contexts.
- Moves set_fact variables to the vars directory, remove unnecessary
intermediate variables, and render them at usage sites to only do logic
on native Ansible/Jinja lists.
- Use defaults/ rather than default filters for several variables.
There is no test with IDEMPOT_CHECK=true since commit 7b78e6872 (disable
idempotency tests (#1872), 2017-10-26)
Remove the related infra from our CI scripts.
This display in a readable (by humans) way the result of most tasks, and
should be way more readable that what we have now, which is frequently a
bunch of unreadable json.
+ some small fixes (using delegated_to instead of when
<control_plane_host>)
- special casing should be in Kubespray, not in the test. It makes no
sense to do something in tests which won't be done in actual usage.
- We don't actually test CoreOS at all in the CI.
This is a followup to 2ba28a338 (Revert "Wait for available API token in
a new namespace (#7045)", 2024-10-25).
While checking for the serviceaccount token is not effective, there is
still a race when creating a Pod directly, because the ServiceAccount
itself might not be created yet.
More details at https://github.com/kubernetes/kubernetes/issues/66689.
This cause very frequent flakes in our CI with spurious failures.
Use a Deployment instead ; it will takes cares of creating the Pods and
retrying ; it also let us use kubectl rollout status instead of manually
checking for the pods.
To reproduce this commit run in bash:
for file in $(ls tests/files/)
do
if ! grep -Rq ${file%.*} .gitlab.ci; then
rm tests/files/${file}
fi
done
This also means that our CI matrix was not accurate.
This is needed for shutdown ordering: while at startup, it's not a
problem that containerd start before dbus (the dbus socket already
exists) it needs to shutdown before dbus to do its cleanup (asking
systemd via dbus to cleanup cgroups).
This is expected to be used in the command module this way:
command:
cmd: "{{ kubectl_apply_stdin }}"
stdin: <... rendered manifests > -> using the 'template' lookup plugin
in most cases.
The advantages over the kube plugin module integrated in kubespray
(which this should replace eventually):
- way easier to modify to take advantage of new features (server-side
apply for instance)
- no need for a separate template tasks + checking the result (which can
introduce problem if the first playbook runs encounters an error).
Those files haven't been touched in roughly 5 years, and pip install on
Kubespray errors out.
The 'Requires:' are outdated, which suggests that no one is using this.
8ff4ad2d8 (preinstall: simplify OS packages selection, 2024-11-04)
removed all usages of ansible.utils.validate (not that many), so the
dependencies is no longer necessary.
config_path was introduced in containerd 1.5.0, and registry.mirrors is
deprecated.
There is no reason to keep the old alternative, so just always use
config_path, and consequently remove the option.
Our README is currently pretty cluttered:
- Part of the README duplicates docs/getting_started/getting-started.md
-> Remove duplicates and extract useful info into the getting-started.md
- General info on Ansible environment troubleshooting
-> remove most of it as it's not specific to Kubespray, move to
docs/ansible/ansible.md
-> split inventory-related stuff of ansible.md into it's own file. This
should host documentation on how to manages Kubespray inventories in the
future.
ansible.md:
- remove the list of "Unused" variables, as:
1. It's not accurate
2. What matters is where users should put their variables
contrib/dind use inventory_builder, which is removed. It overlaps with
the function of kind (Kubernetes in Docker) and has not see change
(apart from linting driven ones) for a long time.
It also does not seem to work (provisioning playbook crash).
This only really help with the easiest part of building your inventory
(listing the hosts) as you still need to edit your groups vars and
similar.
The opaqueness of the script does not really help our users to
understand their own inventory.
Furthermore, there is not really a reason that something which is common
to all the Ansible ecosystem should be done in a special way for
Kubespray.
* Add vars for configuring cilium IP load balancer pools and bgp peer policies
* Cilium 1.16+ Support - Add vars for configuring cilium bgpv2 api & handle cilium_kube_proxy_replacement unsupported values
When using
dns_upstream_forward_extra_opts:
prefer_udp: "" # the option as no value so use empty string to just
# put the key
This is rendered in the dns configmap as ($ for end-of-line)
...
prefer_udp $
...
Note the trailing space.
This triggers https://github.com/kubernetes/kubernetes/issues/36222,
which makes the configmap hardly readable when editing them manually or
simply putting them in a yaml file for inspection.
Trim the concatenation of option + value to get rid of any trailing
space.
* Make Helm's 'atomic' parameter configurable from role variables
* Configure Helm with 'atomic' and 'wait' set to false for generic CNI to prevent kubelet-csr-approver installation failures
We use shell scripts and conf files in some roles (notably, certificates
provisioning), so we need to include them in order for the collection to
work when using the configurations depending on those roles.
* kubeadm: do not ignore preflight errors blindly
The "ignoring all errors" seems to date back to the inception of the
kubeadm support (it was --skip-preflight-check before).
This can mask real errors and prevent users from seeing them.
Do not ignore any errors by default and make the set of ignored errors
configurable.
* download/kubeadm: remove redundant task
The mode is already set by the previous `copy` task.
* Validate kubeadm configs
This should help to fail early when we have invalid kubeadm configs (from
a kubespray bug or a misconfiguration).
* kubeadm-upgrade: remove unnecessary bool cast
* Convert kubeadm join discovery timeout to v1beta4 config
* CI: Ignore kubeadm:Mem errors on some setup.
The new CI does not define k8s_cluster group, so it relies on
kubernetes-sigs/kubespray#11559.
This does not work for upgrade testing (which use the previous release).
We can revert this commit after 2.27.0
We should not rollback our test setup during upgrade test.
The only reason to do that would be for incompatible changes in the test
inventory, and we already checkout master for those (${CI_JOB_NAME}.yml)
Also do some cleanup by removing unnecessary intermediary variables
VirtualMachineInstance resources sometimes temporarily loose their
IP (at least as far as the kubevirt controllers can see).
See https://github.com/kubevirt/kubevirt/issues/12698 for the upstream
bug.
This does not seems to affect actual connection (if it did, our current
CI would not work).
However, our CI execute multiple playbooks, and in particular:
1. The provisioning playbook (which checks that the IPs have been
provisioned by querying the K8S API)
2. Kubespray itself
If any of the VirtualMachineInstance looses its IP between after 1
checked for it, and before 2 starts, the dynamic inventory (which is
invoked when the playbook is launched by ansible-playbook) will not have
an ip for that host, and will try to use the name for ssh, which of
course will not work.
Instead, when we have a valid state during provisioning (all IPs
presents), use it to construct a static inventory which will be used for
the rest of the CI run.
This allows a single source of truth for the virtual machines in a
kubevirt ci-run.
`etcd_member_name` should be correctly handled in kubespray-defaults for
testing the recover cases.
Not constraining the inventory to .ini allows us to use dynamic
inventory, which is needed for simplifying kubevirt jobs inventory.
Also reduces the scope of the ANSIBLE_INVENTORY variable.
VMI in Kubevirt are the abstraction below VirtualMachine.
- We don't really need the extra abstraction of VirtualMachine objects
- Convert the waiting for VMs ip address to use kubernetes.core.k8s_info
and no shell pipeline
We're still getting bug reports circumventing the bug report template
and omitting informations.
Blank issue (aka, not using the form templates) can still be created
using the gh cli, the API, etc. This only disable the possibility in the
Web UI.
- Lookup was not returning a list, making the difference filter spit out
garbage -> query always return a list
- hostvars is a dictionnary, so convert to list before selectattr and
map back to only get keys

Since a2019c1c2 (Add a JSON schema describing the packages install

packages should be installed on a particular host OS.
This has proven too rigid in practice, and the query is pretty
complicated.
Replace this by simply using an array of jinja conditions for the
packages, which should be easier to understand for everyone and more
flexible.
Also remove the associated schema and validation which are no longer

This reverts commit 275c54e810.
Static tokens are no longer created automatically for service account in
Kubernetes. Instead, they are dynamically injected into pods using a
projected volume.
Thus there is no longer a need to check for this (it didn't work anyway,
since the describe output actually contains <none> when there is no
tokens:
{
"attempts": 1,
"changed": false,
"cmd": "set -o pipefail && /usr/local/bin/kubectl describe serviceaccounts default --namespace test | grep Tokens | awk '{print $2}'",
"delta": "0:00:00.075633",

}
)
This leverage the Kubernetes GC to delete kubevirt VMs, by using
ownerReferences, with the CI pod running the playbook as the owner.
This concretely means that the control plane in our CI cluster will
delete the kubevirt VMs associated with a particular ci job as soon as
that pod job is deleted, which usually happens when the job terminates,
(barring errors, which will be addressed in the cluster directly)

Simplify registry mirror rendering in config.toml.
The map filter can extract the host list from mirrors so we can
just unique them and render them without needing to construct vars
for it.
For the registry mirror tls section, we can first extract mirrors
from the dict then filter on only the ones having skip_veridy defined
first and then filter on the ones having true (as the dict might not
have skip_verify defined and that would cause errors of undefined var).
This will speed up and simply the templating.

Dropping the ansible dependencies for ansible-lint will allow us to
catch missing dependencies collections in galaxy.yml. For collections
needed for contrib/ or tests/ (i.e: not part of core kubespray
dependencies), we can just configure ansible-lint to mock them.
This mean it won't check the mocked module parameters, but for those
area of the code base it's an acceptable trade-off.
The fallback_ips tasks are essentially serializing the gathering of one
fact on all the hosts, which can have dramatic performance implications
on large clusters (several minutes).
This is essentially a reversal of 35f248dff0
Being able to run without refreshing the cache facts is not worth it.
We keep fallback_ip for now, simply changing the access to a normal
hostvars variable instead of a custom dictionnary.
Using the hosts directive at the play level prevent those tasks from
being run when using --limit and the group in question is not part of
the limit (ex: running scale.yml on new worker nodes only)
Instead, run on all hosts, and for each group, partition between that
group and '_' (generic group name which is not used; using an empty
string as the group is not supported by ansible.builtin.group_by)

As of writing, only CSI driver versions 3.1.2 to 3.3.1 is available in
this registry. This "officially" supports Kubernetes 1.26 to 1.30. Since
older drivers are not available, I have removed some feature-gating for
those unavailable versions while I was at it. For the cloud provider,
the `latest` image is now missing, and only 1.28.0 to 1.31.0 are
available. I've set the latest of these as the new default.
I also updated the documented default versions, as they were all out of
date and not aligned with actual code defaults.
Nodes to api-server relies by default certificates, and bootstrap
tokens, and there should be no need to generate tokens for every nodes,
even when enabling static token auth.
Testing for group membership with group names makes Kubespray more
tolerant towards the structure of the inventory.
Where 'inventory_hostname in groups["some_group"] would fail if
"some_group" is not defined, '"some_group" in group_names' would not.
- Use proper syntax highlighting for config.rb examples
- Consistent shell style ($ as prompt)
- Use only one way to do things
- Remove OS specific details
The current way to handle a custom inventory in vagrant is a bit
hackish, copy files around and can break Vagrantfile parsing in
cornercase scenarios (removing vagrant inventories, or the inventory
copied into vagrant inventory).
Instead, simply pass additional inventories to the ansible-playbook
command lines as raw arguments with `-i`.
This also makes supporting multiples inventories trivial, so we add a
new `$inventories` variable for that purpose.
Specifying one directory for kubeadm patches is not ideal:
1. It does not allow working with multiples inventories easily
2. No ansible templating of the patch
3. Ansible path searching can sometimes be confusing
Instead, provide the patch directly in a variable, and add some quality
of life to handle components targeting and patch ordering more
explicitly (`target` and `type` which are translated to the kubeadm
scheme which is based on the file name)
kubernetes/control-plane and kubernetes/kubeadm roles both push kubeadm
patches in the same way.
Extract that code and make it a dependency of both.
This is safe because it's only configuration for kubeadm, which only
takes effect when kubeadm is run.
* Update multus to v4.1.0 and clarify cilium compatibility
* Fix: bug introduced by #10934 where the template would break if multus was defined
* Set priorityClassName to system-node-critical for multus pods
Allow the script to be called with a list of components, to only
download new versions checksums for those.
By default, we get new versions checksums for all supported (by the
script) components.
runc upstream does not provide one hash file per assets in their
releases, but one file with all the hashes.
To handle this (and/or any arbitrary format from upstreams), add a
dictionary mapping the name of the download to a lambda function which
transform the file provided by upstream into a dictionary of hashes,
keyed by architecture.
The script is currently limited to one hardcoded URL for kubernetes
related binaries, and a fixed set of architectures.
The solution is three-fold:
1. Use an url template dictionary for each download -> this allow to easily
add support for new downloads.
2. Source the architectures to search from the existing data
3. Enumerate the existing versions in the data and start searching from
the last one until no newer version is found (newer in the version
order sense, irrespective of actual age)
Remove system|kube_master_<resource>_reserved variables.
Those variables are unnecessary because users can simply use the
variables in group_vars if they which to differentiate control plane
nodes from other nodes.
Set conservative defaults for ephemeral-storage and pids for both kube
and system reserved resources.
Working symlinks are dependant on git configuration (when using the playbook as
a git repository, which is common), precisely `git config
core.symlinks`.
While this is enabled by default, some company policies will disable it.
Instead, use import_tasks which should avoid that class of bugs.

Fixes https://github.com/kubernetes-sigs/kubespray/issues/10947
This patch aims to be minimal and intentionally:
- does not change the generation logic for `supersede_domain` and `supersede_search`
- does not change how `nameserverentries` (for NetworkManager) is built
It seems like `nameserverentries` in the "Generate nameservers for resolvconf, including cluster DNS"
task is built the same way as `dhclient_supersede_nameserver_entries_list`.
However, `nameserverentries` in the "Generate nameservers for resolvconf, not including cluster DNS"
task (below) is built differently for some reason. It includes `configured_nameservers` as well.
Due to these differences, I have refrained from reusing the same building logic
(`dhclient_supersede_nameserver_entries_list`) for both.
If the `configured_nameservers` addition can be removed or made to apply
to dhclient as well, we could potentially build a single list and then
generate the `nameserverentries` and `supersede_nameserver` strings from it.

Use a style file as recommended by upstream. This makes for only one
source of truth.
Conserve previous upstream default for MD007 (upstream default changed
here https://github.com/markdownlint/markdownlint/pull/373)
Use gitlab dynamic child pipelines feature to have one source of truth
for the pre-commit jobs, the pre-commit config file.
Use one cache per pre-commit. This should reduce the "fetching cache"
time steps in gitlab-ci, since each job will have a separate cache with
only its hook installed.
We have inconsistent sets of options passed to the playbooks during our
CI runs.
Don't run ansible-playbook directly, instead factorize the execution in
a bash function using all the common flags.
Also remove various ENABLE_* variables and instead directly test for the
relevant conditions at execution time, as this makes it more obvious and
does not force one to go back and forth in the script.
With CentOS, kubespray currently produces the following warning:

When using the kube_node_instancers_with_disks* variables, there were
no configuration block using those to provision disks with the
VirtualBox provider.
This commit fixes it.
Some packages requirements depends on inventory variables
(`kube_proxy_mode` in that case but it could apply to others).
As the case seems pretty rare, instead of adding complexity to pkgs, we
add an escape hatch to use jinja conditions.
That should be revisited if we find ourselves shoehorning lots of logic
in this later on.
Uses the logic introduced in the previous patch to convert all
kubernetes/preinstall/vars/* os specific files to the `pkgs`
dictionary.
Some niceties for devs:
- always validate the `pkgs` variable to catch mistakes in CI.
- ensure that `pkgs` is always sorted. This makes it easier to find the
packages you're looking for.
Adds infrastructure to install OS packages depending not only on OS
(family, versions, etc) but on groups.
All the informations related to a particular package should reside in
the `pkgs` dictionnary, which takes inspiration from the `downloads`
dictionary structure.
Since the structure we're setting in place for installing packages has
some complexity, add a JSON schema to avoid frustrating errors when
modifying the informations (adding/removing packages install).
This reverts commit 4b0a134bc9.
The mentionned PR break scale.yml. This goes back to the status quo
until a proper fix can be provided, at which point we'll reapply the
PR.

* Remove leftover files for Coreos
Coreos was replaced by flatcar in 058438a25 but the file was copied
instead of moved.
* Remove workarounds for resolved ansible issues
* boostrap: Use first_found to include per distro
Using directly ID and VARIANT_ID with first_found allow for less manual
includes.
Distro "families" are simply handled by symlinks.
* boostrap: don't set ansible_python_interpreter
- Allows users to override the chosen python_interpreter with group_vars
easily (group_vars have lesser precedence than facts)
- Allows us to use vars at the task scope to use a virtual env
Ansible python discovery has improved, so those workarounds should not
be necessary anymore.
Special workaround for Flatcar, due to upstream ansible not willing to
support it.

The new version brings the following improvements:
- remove having to resort to python python to limit tags (it it slower than
the sh equivalent as python has a somewhat significant startup time).
- Introduce a concept of min version so that it can only get Kubernetes
version supported by Kubespray.
- Fix an issue with kata changing their file scheme (the arch
specifically)
- Now download sha256/sha256sum files if provided rather than
downloading the full file and computing the hash
- A few minor style tweaks

Fixes bug for retrieving images with tags containing image digests.
Script now gets images from jobs and cronjobs as well.
New env variable DESTINATION_REGISTRY to push to another registry
instead of local registry.
New env variable IMAGES_FROM_FILE to pull images listed in a file

New env variable REGISTRY_PORT to override port (default is 5000).
Under the original code, leader election failed for ingress controllers
as a result of mismatch between election-id in the controller config,
and the resourceName in the relevant rule of role 'ingress-nginx'.
This appeared in the controller logs.
To fix the issue, a command-line option was added to container
execution (--election-id=...).
Now, the election-id agrees with the resourceName provided in
the role-ingress-nginx.yml file. A comment in that file was
changed to reflect the new logic.

Handle all old dns domains:
- for nodelocaldns: in the same server block as the current dns_domain
- for coredns: uffix rewrite of each of the old dns domains to the
current one
The old version of the script downloaded all binaries and generated file checksums locally.
This was a slow process since all binaries of all architectures needed to be downloaded.
The new version simply downloads the .sha256 files containing the binary checksum in text
form which saves a lot of traffic and time.

In the case were vagrant is not invoked directly from the repository,
but from another location, and the Vagrantfile is "included" into
another, we need to be able to specify where the location of the vagrant
directory is, as of now it's hardcoded relative to the Vagrantfile
location. This commit fix it.
* ignore_unreachable for etcd dir cleanup
ignore_errors ignores errors occur within "file" module. However, when
the target node is offline, the playbook will still fail at this task
with node "unreachable" state. Setting "ignore_unreachable: true" allows
the playbook to bypass offline nodes and move on to proceed recovery
tasks on remaining online nodes.

different classes of hosts. For each class there are options for allocating
floating IP addresses or not.
-Master nodes with etcd
-Master nodes without etcd
-Control plane nodes with etcd
-Control plane nodes without etcd
- Standalone etcd hosts
- Kubernetes worker nodes
Note that the Ansible script will report an invalid configuration if you wind up
with an even number of etcd instances since that is not a valid configuration. This
restriction includes standalone etcd nodes that are deployed in a cluster along with
master nodes with etcd replicas. As an example, if you have three master nodes with
etcd replicas and three standalone etcd nodes, the script will fail since there are
now six total etcd replicas.
