Update hashes and set default k8s version to 1.16.9 (#6032)

* etcd: etcd-events doesn't depend on etcd_cluster_setup

Signed-off-by: Etienne Champetier <champetier.etienne@gmail.com>

* etcd: remove condition already present on include_tasks

Signed-off-by: Etienne Champetier <champetier.etienne@gmail.com>

* etcd: fix scaling up

Signed-off-by: Etienne Champetier <champetier.etienne@gmail.com>

* etcd: use *access_addresses, do not delegate to etcd[0]

We want to wait for the full cluster to be healthy,
so use all the cluster addresses
Also we should be able to run the playbook when etcd[0] is down
(not tested), so do not delegate to etcd[0]

Signed-off-by: Etienne Champetier <champetier.etienne@gmail.com>

* etcd: use failed_when for health check

unhealthy cluster is expected on first run, so use failed_when
instead of ignore_errors to remove scary red messages

Also use run_once

* kubernetes/preinstall: ensure ansible_fqdn is up to date after changing /etc/hosts

Signed-off-by: Etienne Champetier <champetier.etienne@gmail.com>

* kubernetes/master: regenerate apiserver cert if needed

 To deploy the cluster you can use :
 
-[**kubespray-cli**](https://github.com/kubespray/kubespray-cli) <br>
-**Ansible** usual commands and [**inventory builder**](https://github.com/kubernetes-incubator/kubespray/blob/master/contrib/inventory_builder/inventory.py) <br>
-**vagrant** by simply running `vagrant up` (for tests purposes) <br>
+### Ansible

-*  [Kubespray vs ...](docs/comparisons.md)
-*  [Getting started](docs/getting-started.md)

+```ShellSession
+# Install dependencies from ``requirements.txt``
+sudo pip install -r requirements.txt
 
-Supported Linux distributions
-===============
+# Copy ``inventory/sample`` as ``inventory/mycluster``
+cp -rfp inventory/sample inventory/mycluster
 
-* **Container Linux by CoreOS**
-* **Debian** Jessie
-* **Ubuntu** 16.04
-* **CentOS/RHEL** 7
+# Update Ansible inventory file with inventory builder
+declare -a IPS=(10.10.1.3 10.10.1.4 10.10.1.5)
+CONFIG_FILE=inventory/mycluster/inventory.ini python3 contrib/inventory_builder/inventory.py ${IPS[@]}
+
+# Review and change parameters under ``inventory/mycluster/group_vars``
+cat inventory/mycluster/group_vars/all/all.yml
+cat inventory/mycluster/group_vars/k8s-cluster/k8s-cluster.yml
+
+# Deploy Kubespray with Ansible Playbook - run the playbook as root
+# The option `--become` is required, as for example writing SSL keys in /etc/,
+# installing packages and interacting with various systemd daemons.
+# Without --become the playbook will fail to run!
+ansible-playbook -i inventory/mycluster/inventory.ini --become --become-user=root cluster.yml
+```
+
+Note: When Ansible is already installed via system packages on the control machine, other python packages installed via `sudo pip install -r requirements.txt` will go to a different directory tree (e.g. `/usr/local/lib/python2.7/dist-packages` on Ubuntu) from Ansible's (e.g. `/usr/lib/python2.7/dist-packages/ansible` still on Ubuntu).
+As a consequence, `ansible-playbook` command will fail with:
+
+```raw
+ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path.
+```
+
+probably pointing on a task depending on a module present in requirements.txt (i.e. "unseal vault").
+
+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`.
+
+### Vagrant
+
+For Vagrant we need to install python dependencies for provisioning tasks.
+Check if Python and pip are installed:
+
+```ShellSession
+python -V && pip -V
+```
+
+If this returns the version of the software, you're good to go. If not, download and install Python from here <https://www.python.org/downloads/source/>
+Install the necessary requirements
+
+```ShellSession
+sudo pip install -r requirements.txt
+vagrant up
+```

The kubelet might break on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).
 
-Note: kubernetes doesn't support newer docker versions. Among other things kubelet currently breaks on docker's non-standard version numbering (it no longer uses semantic versioning). To ensure auto-updates don't break your cluster look into e.g. yum versionlock plugin or apt pin).
+## Requirements
 
-Note 2: rkt support as docker alternative is limited to control plane (etcd and
-kubelet). Docker is still used for Kubernetes cluster workloads and network
-plugins' related OS services. Also note, only one of the supported network
-plugins can be deployed for a given single cluster.
+- **Minimum required version of Kubernetes is v1.15**
+- **Ansible v2.7.16 and python-netaddr is installed on the machine that will run Ansible commands**
+- **Jinja 2.9 (or newer) is required to run the Ansible Playbooks**
+- The target servers must have **access to the Internet** in order to pull docker images. Otherwise, additional configuration is required (See [Offline Environment](https://github.com/kubernetes-sigs/kubespray/blob/master/docs/downloads.md#offline-environment))
+- The target servers are configured to allow **IPv4 forwarding**.
+- **Your ssh key must be copied** to all the servers part of your inventory.
+- The **firewalls are not managed**, you'll need to implement your own rules the way you used to.
+    in order to avoid any issue during deployment you should disable your firewall.
+- If kubespray is ran from non-root user account, correct privilege escalation method
+    should be configured in the target servers. Then the `ansible_become` flag
+    or command parameters `--become or -b` should be specified.
 
-Requirements
---------------
+Hardware:
+These limits are safe guarded by Kubespray. Actual requirements for your workload can differ. For a sizing guide go to the [Building Large Clusters](https://kubernetes.io/docs/setup/cluster-large/#size-of-master-and-master-components) guide.

+
+- [kube-router](docs/kube-router.md): Kube-router is a L3 CNI for Kubernetes networking aiming to provide operational
+    simplicity and high performance: it uses IPVS to provide Kube Services Proxy (if setup to replace kube-proxy),
+    iptables for network policies, and BGP for ods L3 networking (with optionally BGP peering with out-of-cluster BGP peers).
+    It can also optionally advertise routes to Kubernetes cluster Pods CIDRs, ClusterIPs, ExternalIPs and LoadBalancerIPs.
+
+- [macvlan](docs/macvlan.md): Macvlan is a Linux network driver. Pods have their own unique Mac and Ip address, connected directly the physical (layer 2) network.
+
+- [multus](docs/multus.md): Multus is a meta CNI plugin that provides multiple network interface support to pods. For each interface Multus delegates CNI calls to secondary CNI plugins such as Calico, macvlan, etc.
 
 The choice is defined with the variable `kube_network_plugin`. There is also an
 option to leverage built-in cloud provider networking instead.

 1. An issue is proposing a new release with a changelog since the last release
-2. At least one of the [OWNERS](OWNERS) must LGTM this release
-3. An OWNER runs `git tag -s $VERSION` and inserts the changelog and pushes the tag with `git push $VERSION`
-4. The release issue is closed
-5. An announcement email is sent to `kubernetes-dev@googlegroups.com` with the subject `[ANNOUNCE] Kubespray $VERSION is released`
+2. At least one of the [approvers](OWNERS_ALIASES) must approve this release
+3. An approver creates [new release in GitHub](https://github.com/kubernetes-sigs/kubespray/releases/new) using a version and tag name like `vX.Y.Z` and attaching the release notes
+4. An approver creates a release branch in the form `release-vX.Y`
+5. The corresponding version of [quay.io/kubespray/kubespray:vX.Y.Z](https://quay.io/repository/kubespray/kubespray) docker image is built and tagged
+6. The `KUBESPRAY_VERSION` variable is updated in `.gitlab-ci.yml`
+7. The release issue is closed
+8. An announcement email is sent to `kubernetes-dev@googlegroups.com` with the subject `[ANNOUNCE] Kubespray $VERSION is released`
 
 ## Major/minor releases, merge freezes and milestones
 
-* Kubespray does not maintain stable branches for releases. Releases are tags, not
-  branches, and there are no backports. Therefore, there is no need for merge
-  freezes as well.
+* Kubespray maintains one branch for major releases (vX.Y). Minor releases are available only as tags.
+
+* Security patches and bugs might be backported.
 
 * Fixes for major releases (vX.x.0) and minor releases (vX.Y.x) are delivered
   via maintenance releases (vX.Y.Z) and assigned to the corresponding open

+# Kubespray DIND experimental setup
+
+This ansible playbook creates local docker containers
+to serve as Kubernetes "nodes", which in turn will run
+"normal" Kubernetes docker containers, a mode usually
+called DIND (Docker-IN-Docker).
+
+The playbook has two roles:
+- dind-host: creates the "nodes" as containers in localhost, with
+  appropriate settings for DIND (privileged, volume mapping for dind
+  storage, etc).
+- dind-cluster: customizes each node container to have required
+  system packages installed, and some utils (swapoff, lsattr)
+  symlinked to /bin/true to ease mimicking a real node.
+
+This playbook has been test with Ubuntu 16.04 as host and ubuntu:16.04
+as docker images (note that dind-cluster has specific customization
+for these images).
+
+The playbook also creates a `/tmp/kubespray.dind.inventory_builder.sh`
+helper (wraps up running `contrib/inventory_builder/inventory.py` with
+node containers IPs and prefix).
+
+## Deploying
+
+See below for a complete successful run:
+
+1. Create the node containers
+
+~~~~
+# From the kubespray root dir
+cd contrib/dind
+pip install -r requirements.txt
+
+ansible-playbook -i hosts dind-cluster.yaml
+
+# Back to kubespray root
+cd ../..
+~~~~
+
+NOTE: if the playbook run fails with something like below error
+message, you may need to specifically set `ansible_python_interpreter`,
+see `./hosts` file for an example expanded localhost entry.
+
+~~~
+failed: [localhost] (item=kube-node1) => {"changed": false, "item": "kube-node1", "msg": "Failed to import docker or docker-py - No module named requests.exceptions. Try `pip install docker` or `pip install docker-py` (Python 2.6)"}
+~~~
+
+2. Customize kubespray-dind.yaml
+
+Note that there's coupling between above created node containers
+and `kubespray-dind.yaml` settings, in particular regarding selected `node_distro`
+(as set in `group_vars/all/all.yaml`), and docker settings.
+
+~~~
+$EDITOR contrib/dind/kubespray-dind.yaml
+~~~
+
+3. Prepare the inventory and run the playbook
+
+~~~
+INVENTORY_DIR=inventory/local-dind
+mkdir -p ${INVENTORY_DIR}
+rm -f ${INVENTORY_DIR}/hosts.ini
+CONFIG_FILE=${INVENTORY_DIR}/hosts.ini /tmp/kubespray.dind.inventory_builder.sh
+
+ansible-playbook --become -e ansible_ssh_user=debian -i ${INVENTORY_DIR}/hosts.ini cluster.yml --extra-vars @contrib/dind/kubespray-dind.yaml
+~~~
+
+NOTE: You could also test other distros without editing files by
+passing `--extra-vars` as per below commandline,
+replacing `DISTRO` by either `debian`, `ubuntu`, `centos`, `fedora`:
+
+~~~
+cd contrib/dind
+ansible-playbook -i hosts dind-cluster.yaml --extra-vars node_distro=DISTRO
+
+cd ../..
+CONFIG_FILE=inventory/local-dind/hosts.ini /tmp/kubespray.dind.inventory_builder.sh
+ansible-playbook --become -e ansible_ssh_user=DISTRO -i inventory/local-dind/hosts.ini cluster.yml --extra-vars @contrib/dind/kubespray-dind.yaml --extra-vars bootstrap_os=DISTRO
+~~~
+
+## Resulting deployment
+
+See below to get an idea on how a completed deployment looks like,
+from the host where you ran kubespray playbooks.

+## Using ./run-test-distros.sh
+
+You can use `./run-test-distros.sh` to run a set of tests via DIND,
+and excerpt from this script, to get an idea:
+
+~~~
+# The SPEC file(s) must have two arrays as e.g.
+# DISTROS=(debian centos)
+# EXTRAS=(
+#     'kube_network_plugin=calico'
+#     'kube_network_plugin=flannel'
+#     'kube_network_plugin=weave'
+# )
+# that will be tested in a "combinatory" way (e.g. from above there'll be
+# be 6 test runs), creating a sequenced <spec_filename>-nn.out with each output.
+#
+# Each $EXTRAS element will be whitespace split, and passed as --extra-vars
+# to main kubespray ansible-playbook run.
+~~~
+
+See e.g. `test-some_distros-most_CNIs.env` and
+`test-some_distros-kube_router_combo.env` in particular for a richer
+set of CNI specific `--extra-vars` combo.

+# Deploy MetalLB into Kubespray/Kubernetes
+```
+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.
+
+## Install
+```
+Defaults can be found in contrib/metallb/roles/provision/defaults/main.yml. You can override the defaults by copying the contents of this file to somewhere in inventory/mycluster/group_vars such as inventory/mycluster/groups_vars/k8s-cluster/addons.yml and making any adjustments as required.

 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.
+
+## 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.
+```
+ansible-playbook --ask-become -i inventory/sample/k8s_heketi_inventory.yml contrib/network-storage/heketi/heketi.yml
+```
+
+## Tear down
+```
+ansible-playbook --ask-become -i inventory/sample/k8s_heketi_inventory.yml contrib/network-storage/heketi/heketi-tear-down.yml
+```
+
+Add `--extra-vars "heketi_remove_lvm=true"` to the command above to remove LVM packages from the system
