The path of kubeconfig should be configurable, and its default value
is /etc/kubernetes/admin.conf. Most paths of the file are configurable
but some were not. This make those configurable.
The addon-resizer container can reduce resource limits of cpu and
memory of metrics-server container in the pod, and that caused
OOMKilled.
In addition, the original metrics-server manifest doesn't contain
the addon-resizer container as [1].
So this adds metrics_server_resizer option to control the addon-resizer
container deployment and the default value is false to make it stable
for most environments.
This is a cherry-pick of 8d3961edbe

"allowPrivilegeEscalation: false" blocks deploying metrics-server

When using Calico with:

using --no-cache-dir flag in pip install ,make sure downloaded packages
by pip don't cached on system . This is a best practice which make sure
to fetch from repo instead of using local cached one . Further , in case
of Docker Containers , by restricting caching , we can reduce image size.
In term of stats , it depends upon the number of python packages
multiplied by their respective size . e.g for heavy packages with a lot
of dependencies it reduce a lot by don't caching pip packages.

this updates the documentation.
Previously IDs of container images were gotten from tar files of container
images but that way was wrong. If multiple json files are contained in a
tar file, the script got multiple IDs and tried to pass these IDs on
`docker tag` command. Then the command was failed.
This updates the script to get image IDs from `docker image inspect` command
to fix this issue.
In addition, this adds a check a registry container exists already or not
before deploying registry container to avoid a container conflict failure.

Since K8S 1.21, BoundServiceAccountTokenVolume feature gate is in beta stage, thus activated by default (anyone who follows CSI guidelines has enabled AllAlpha and faced the issue before 1.21).
With this feature, SA tokens are regenerated every hour.
As a consequence for Calico CNI, token in /etc/cni/net.d/calico-kubeconfig copied from /var/run/secrets/kubernetes.io/serviceaccount in install-cni initContainer expires after one hour and any pod creation fails due to unauthorization.
Calico pods need to be restarted so that /etc/cni/net.d/calico-kubeconfig is updated with the new SA token.
follow new naming conventions for gcr's coredns image.
starting from 1.21 kubeadm assumes it to be `coredns/coredns`:
this causes the kubeadm deployment being unable to pull image, beacuse `v`
was also added in image tag, until the role `kubernetes-apps` ovverides
it with the old name, which is only compatible with <=1.7.
Backward comptability with kubeadm <=1.20 is mantained checking
kubernetes version and falling back to old names (`coredns:1.xx`) when
the version is less than 1.21

Context: Load-balancing in Exoscale is performed by associating many

me at least once.

This PR is to move the cilium kvstore options to the configmap
rather than specifying them in the deployment as args. This
is not technically necessary but keeping all the options in
one place is probably not a bad idea.
Tested with cilium 1.9.5.
When attempting a fresh install without cilium_ipsec_enabled I ran
into the following error:
failed: [k8m01] (item={'name': 'cilium', 'file': 'cilium-secret.yml', 'type': 'secret', 'when': 'cilium_ipsec_enabled'}) =>

Starting with Cilium v1.9 the default ipam mode has changed to "Cluster
Scope". See:
https://docs.cilium.io/en/v1.9/concepts/networking/ipam/
With this ipam mode Cilium handles assigning subnets to nodes to use
for pod ip addresses. The default Kubespray deploy uses the Kube
Controller Manager for this (the --allocate-node-cidrs
kube-controller-manager flag is set). This makes the proper ipam mode
for kubespray using cilium v1.9+ "kubernetes".
Tested with Cilium 1.9.5.
This PR also mounts the cilium-config ConfigMap for this variable
to be read properly.
In the future we can probably remove the kvstore and kvstore-opt
Cilium Operator args since they can be in the ConfigMap. I will tackle
that after this merges.
When upgrading cilium from 1.8.8 to 1.9.5 I ran into the following
error:
level=error msg="Unable to update CRD" error="customresourcedefinitions.apiextensions.k8s.io
\"ciliumnodes.cilium.io\" is forbidden: User \"system:serviceaccount:kube-system:cilium-operator\"
cannot update resource \"customresourcedefinitions\" in API group \"apiextensions.k8s.io\" at the
cluster scope" name=CiliumNode/v2 subsys=k8s
The fix was to add the update verb to the clusterrole. I also added
create to match the clusterrole created by the cilium helm chart.
DNSSEC is off by default on ubuntu/bionic64 (18.04) as per resolved.conf(5).
These tasks are artefacts of obsolete infra configuration, and no longer needed.
Further removing these tasks resolves the issue that the tasks always reports

actual modification of /etc/systemd/resolved.conf.

* contrib/terraform/exoscale: Rework SSH public keys
Exoscale has a few limitations with `exoscale_ssh_keypair` resources.
Creating several clusters with these scripts may lead to an error like:
```
Error: API error ParamError 431 (InvalidParameterValueException 4350): The key pair "lj-sc-ssh-key" already has this fingerprint
```
This patch reworks handling of SSH public keys. Specifically, we rely on
the more cloud-agnostic way of configuring SSH public keys via
`cloud-init`.
* contrib/terraform/exoscale: terraform fmt
* contrib/terraform/exoscale: Add terraform validate
* contrib/terraform/exoscale: Inline public SSH keys
The Terraform scripts need to install some SSH key, so that Kubespray
(i.e., the "Ansible part") can take over. Initially, we pointed the
Terraform scripts to `~/.ssh/id_rsa.pub`. This proved to be suboptimal:
Operators sharing responbility for a cluster risk unnecessarily replacing resources.
Therefore, it has been determined that it's best to inline the public
SSH keys. The chosen variable `ssh_public_keys` provides some uniformity
with `contrib/azurerm`.
* Fix Terraform Exoscale test
* Fix Terraform 0.14 test
* update local-path-storage config template to version v0.0.19

This new check also checks the activeness of network manager, as

This variable was added as KUBE_MASTERS_MASTERS. That's probably a typo.
Remove the redundant `_MASTERS` suffix. Also, document the variable in the
help message.
TASK [Generate a list of information about the images on a node]
registers list of container images to docker_images.
Then the next TASK [Set pull_required if the desired image is not
yet loaded] does based on expecting images are registered.
However sometimes the first TASK was failed as [1] but the failure
is ignored due to failed_when:false and it makes another issue.
This removes this unnecessary failed_when to detect the failure
at the point.
In addition, this removes no_log:true also because the output doesn't
contain any sensitive data and now it just makes debugging difficult.

no_proxy is a pain to get right, and having proxy variables present causes issues
(k8s components get proxy configuration after upgrade, see #7100)
It's better to only configure what require proxy:

- the package manager + apt_key
- the download tasks

We need to specify either external_openstack_tenant_name or
external_openstack_tenant_id. Those values were checked by seeing they
are defined or they have actual values separately.
However those values are always defined because of the following code
of openstack/defaults/main.yml:
external_openstack_tenant_id: "{{ lookup('env','OS_TENANT_ID')| default(lookup('env','OS_PROJECT_ID'),true) }}"
external_openstack_tenant_name: "{{ lookup('env','OS_TENANT_NAME')| default(lookup('env','OS_PROJECT_NAME'),true) }}"
So even if not specifying both values, those checks could not detect
the misconfiguration. This fixes this to detect the misconfiguration.

* Update README.md
On OpenStack history, we used to call "tenant" for separeted namespace.
However we use "project" now instead.
Then we have replaced "tenant" with "project". Then all "TENANT" variables
also are renamed to "PROJECT".
This makes Kubespray search "PROJECT" variable also for newer OpenStack
clouds.

flannel, ovn and multus network plugins did not support all taint keys. This
update changes the tolerations to support them all.
According to the documentation:
```
There are two special cases: An empty key with operator Exists matches all keys,
values and effects which means this will tolerate everything. An empty effect matches
all effects with key key.
```
Usage of the empty `key` and `effect` ensures the network plugin daemonset will
be deployed on every nodes (ex: in case of custom taints, or NoExecute effect)
Since MetalLB v0.8[1], metallb:speaker has started publishing an event
nodeAssigned on k8s resource.
To support MetalLB v0.8+, this allows metallb:speaker to create events.
[1]: 5cc6e23776 (diff-60053ad6fecb5a3cfabb6f3d9e720899R246)
Since weave 2.5.1, `NoExecute` taint effect is no more supported,
this changes the daemonset tolerations to change this behavior.
Also remove the toleration key `CriticalAddonsOnly` not required anymore.
If running MetalLB v0.7.3 on k8s v1.18.2, metallb pods output the
following parsing error of v1.ServiceList:
$ kubectl logs controller-dbb46cf84-fw8h8 -n metallb-system

Due to lack of requirements installation on Azure README, the error
can happen:
"The ipaddr filter requires python's netaddr be installed on the
ansible controller"
It is nice to add the installation for Azure users.
The 98e7a07fba commit udpates the
dashboard version to 2.0.0 but it enable skip login flag wasn't
updated. This change updates its identation to avoid issues when
dashboard_skip_login is enabled.
apply-rg.sh was for Azure command version 1("azure" command) and the
command is old and version 2("az" command) is officially used today.
apply-rg_2.sh was for the version 2. In addition, the README[1] says
we need to run apply-rg.sh for applying templates.
This renames apply-rg_2.sh to apply-rg.sh for common usages of the
version 2.
[1]: https://github.com/kubernetes-sigs/kubespray/tree/master/contrib/azurerm#generating-and-applying
The ansible-playbook needs to ssh-login to Azure virtual machines with
ssh keypair, and users need to specify ssh_public_keys for their own
ssh public key. The change of ssh_public_keys is mandatory.
So this updates contrib/azurerm/README.md to explain that.
In addition, the path of all.yml was wrong. That also is updated with
this.
apply-rg_2.sh uses 'az group deployment' command but the command is
deprecated like the following warning message:
"This command is implicitly deprecated because command group
'group deployment' is deprecated and will be removed in a future release.
Use 'deployment group' instead."
This updates these deprecated commands.
FYI: The command has been deprecated since [1] on azure-cli side.

cloud_provider option exists in ./inventory/sample/group_vars/all/all.yml
In addition, the quick start shows to create configuration by copying
./inventory/sample. So this updates path of all.yml for fitting the above.
* Add proxy support to CRI-O service
The crio.service requires proxy environment variables when it's
deployed behind a corporated network. This change creates a systemd
configuration file when the proxy variables are defined.
* Remove unnecesary crio's tasks
The playbook that bootstrap openSUSE servers assumes that the
/etc/sysconfig/proxy file exists but the execution fails when
these file is not present. This change guarantees its existence.
The Terraform installation part states that is for CentOS 7, but the echo command refers to OS X binary. Updated the echo command to use the Linux version.

On CentOS 8 with proxy ansible render inline `proxy` and `module_hotfixes` options.
For example:
`proxy=http://127.0.0.1:3128module_hotfixes=True`
But expected result:
```
proxy=http://127.0.0.1:3128
module_hotfixes=True
```
* Use ini_file module for work with ini files
* Prevent duplicates proxy= option in /etc/yum.conf
Module `lineinfile` is weak, use most powerful module `ini_file` and add or remove `proxy=` when `http_proxy` is defined or not.

Before this commit, the bastion entry in the inventary was not honored,
so machines behind firewalls or with unrouted addresses were not
reachable for ansible.
The variable is defined in `kubernetes/preinstall` role and used in several roles. Since `kubernetes/preinstall` is not always included when `ansible-playbook` is run with tag selectors (see #5734 for reason), they will fail, or individual roles must copy the same fact definitions (as in #3846). Moving the definition to the always-included `kubespray-defaults` role will resolve the dependency problem.
- This solves issue #5721 & #5713 (dupes)
- Provide a cleaner default usage pattern for the download role
around etcd that supports 'host' and 'docker' properly
- Extract the 'etcdctl' as a separate task install piece and reuse it where

Defaults to the upstream default https://docs.projectcalico.org/v3.9/reference/felix/configuration
so nothing should change for existing deployments.
This allows coexistence with other firewall management technologies.
* Add a note to the sample config
* Add docker-ce 19.03 packages for Debian & Ubuntu
K8s has updated the recommended Docker version to 19.03. More
specifically it should be 19.03.4, but since we used 18.06.7 instead of
.2, I'm assuming the latest patch version should be used here as well.
* Add docker 19.03 for redhat
The 'regexp' parameter matches last occurrence of a line starting with 'proxy=' and replaces it with the one defined in 'line' parameter. If no match - it works same way as before. This fixes resuming cluster deployments failed after that task (if there was no more than one line starting with 'proxy' in the yum.conf file - this condition should also be reassured with the change introduced here) eg. if they were initiated with Terraform.

## How to become a contributor and submit your own code
### Environment setup
It is recommended to use filter to manage the GitHub email notification, see [examples for setting filters to Kubernetes Github notifications](https://github.com/kubernetes/community/blob/master/communication/best-practices.md#examples-for-setting-filters-to-kubernetes-github-notifications)
To install development dependencies you can use `pip install -r tests/requirements.txt`
#### Linting
Kubespray uses `yamllint` and `ansible-lint`. To run them locally use `yamllint .` and `ansible-lint`
#### Molecule
[molecule](https://github.com/ansible-community/molecule) is designed to help the development and testing of Ansible roles. In Kubespray you can run it all for all roles with `./tests/scripts/molecule_run.sh` or for a specific role (that you are working with) with `molecule test` from the role directory (`cd roles/my-role`).
When developing or debugging a role it can be useful to run `molecule create` and `molecule converge` separately. Then you can use `molecule login` to SSH into the test environment.
#### Vagrant
Vagrant with VirtualBox or libvirt driver helps you to quickly spin test clusters to test things end to end. See [README.md#vagrant](README.md)

One way of solving this would be to uninstall the Ansible package and then, to install it via pip but it is not always possible.
A workaround consists of setting `ANSIBLE_LIBRARY` and `ANSIBLE_MODULE_UTILS` environment variables respectively to the `ansible/modules` and `ansible/module_utils` subdirectories of pip packages installation location, which can be found in the Location field of the output of `pip show [package]` before executing `ansible-playbook`.
A simple way to ensure you get all the correct version of Ansible is to use the [pre-built docker image from Quay](https://quay.io/repository/kubespray/kubespray?tab=tags).

MetalLB hooks into your Kubernetes cluster, and provides a network load-balancer implementation. In short, it allows you to create Kubernetes services of type “LoadBalancer” in clusters that don’t run on a cloud provider, and thus cannot simply hook into paid products to provide load-balancers.
```
This playbook aims to automate [this](https://metallb.universe.tf/concepts/layer2/). It deploys MetalLB into kubernetes and sets up a layer 2 loadbalancer.

Then execute change to the kubespray root folder, and execute (supposing that the machines are all using ubuntu):
If your machines are not using Ubuntu, you need to change the `--user=ubuntu` to the correct user. Alternatively, if your Kubernetes machines are using one OS and your GlusterFS a different one, you can instead specify the `ansible_ssh_user=<correct-user>` variable in the inventory file that you just created, for each machine/VM:

# Deploy Heketi/Glusterfs into Kubespray/Kubernetes
This playbook aims to automate [this](https://github.com/heketi/heketi/blob/master/docs/admin/install-kubernetes.md) tutorial. It deploys heketi/glusterfs into kubernetes and sets up a storageclass.
## Important notice
> Due to resource limits on the current project maintainers and general lack of contributions we are considering placing Heketi into a [near-maintenance mode](https://github.com/heketi/heketi#important-notice)
## Client Setup
Heketi provides a CLI that provides users with a means to administer the deployment and configuration of GlusterFS in Kubernetes. [Download and install the heketi-cli](https://github.com/heketi/heketi/releases) on your client machine.
## Install
Copy the inventory.yml.sample over to inventory/sample/k8s_heketi_inventory.yml and change it according to your setup.
Container image collecting script for offline deployment
This script has two features:
(1) Get container images from an environment which is deployed online.
(2) Deploy local container registry and register the container images to the registry.
Step(1) should be done online site as a preparation, then we bring the gotten images
to the target offline environment.
Then we will run step(2) for registering the images to local registry.
Step(1) can be operated with:
```shell
manage-offline-container-images.sh create
```
Step(2) can be operated with:
```shell
manage-offline-container-images.sh register
```
## generate_list.sh
This script generates the list of downloaded files and the list of container images by `roles/download/defaults/main.yml` file.
Run this script will generates three files, all downloaded files url in files.list, all container images in images.list, all component version in generate.sh.
```shell
bash generate_list.sh
tree temp
temp
├── files.list
├── generate.sh
└── images.list
0 directories, 3 files
```
In some cases you may want to update some component version, you can edit `generate.sh` file, then run `bash generate.sh | grep 'https' > files.list` to update file.list or run `bash generate.sh | grep -v 'https'> images.list` to update images.list.
