704a054064 Delete misnammed kubeadm-version.yml
The important action in kubeadm-version.yml is the templating of the configuration,
not finding / setting the version

3c8ad073cd Stop using kubeadm to update server in kubeconfigs (#7338)
Using `kubeadm init phase kubeconfig all` breaks kubelet client certificate rotation
as we are missing `kubeadm init phase kubelet-finalize all` to point to `kubelet-client-current.pem`

kubeconfig format is stable so let's just use lineinfile,
this will avoid other future breakage

This revert to the logic before 6fe2248314

fbdc2b3e20 Fix proxy usage when *_PROXY are present in environment (#7309)
Since a790935d02 all proxy users
should be properly configured

Now when you have *_PROXY vars in your environment it can leads to failure
if NO_PROXY is not correct, or to persistent configuration changes
as seen with kubeadm in 1c5391dda7

Instead of playing constant whack-a-bug, inject empty *_PROXY vars everywhere
at the play level, and override at the task level when needed

40857b9859 Ensure kubeadm doesn't use proxy (#7275)
* Move proxy_env to kubespray-defaults/defaults

There is no reasons to use set_facts here

Signed-off-by: Etienne Champetier <e.champetier@ateme.com>

* Ensure kubeadm doesn't use proxy

*_proxy variables might be present in the environment (/etc/environment, bash profile, ...)
When this is the case we end up with those proxy configuration in /etc/kubernetes/manifests/kube-*.yaml manifests

We cannot unset env variables, but kubeadm is nice enough to ignore empty vars

Fix etcd install with docker and etcd_kubeadm_enabled (#5777)
- 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
    appropriate
  - Update the kubeadm-etcd task to reflect the above change

Upgrade container-engine after draining (#5601)
* Run 'container-engine' after drain.

Move possibly disruptive role 'container-engine' to run after the node
is drained.

As that role have to be run on non-cluster nodes as well (etcd and
calico-rr), and those nodes are not drained, add play for that case.

* Check if api is up before upgrade.

If container engine is restarted in previous role, api controller can
take some time to start. This check ensures api is up before upgrade.
