Release 2.15 (#35)
2559809 
* Only use stat get_checksum: yes when needed (kubernetes-sigs#7270)

By default Ansible stat module compute checksum, list extended attributes and find mime type
To find all stat invocations that really use one of those:
git grep -F stat. | grep -vE 'stat.(islnk|exists|lnk_source|writeable)'

(cherry picked from commit de1d9df)

Conflicts:
	roles/etcd/tasks/check_certs.yml

* Add kube-ipvs0/nodelocaldns to NetworkManager unmanaged-devices (kubernetes-sigs#7315)

On CentOS 8 they seem to be ignored by default, but better be extra safe
This also make it easy to exclude other network plugin interfaces

Signed-off-by: Etienne Champetier <[email protected]>
(cherry picked from commit e442b1d)

* Stop using kubeadm to update server in kubeconfigs (kubernetes-sigs#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 6fe2248

Signed-off-by: Etienne Champetier <[email protected]>
(cherry picked from commit c9c0c01)

* kubeadm-config.v1beta2.yaml.j2: etcd log level arg (kubernetes-sigs#7339)

According to [etcd's docs](https://etcd.io/docs/v3.4.0/op-guide/configuration/#--log-package-levels), argument 'log-package-levels' should not contain underscores.

(cherry picked from commit b7c2265)

* Remove pre kubeadm cert migration tasks

apiserver.pem is not used since ddffdb6

Signed-off-by: Etienne Champetier <[email protected]>
(cherry picked from commit fedd671)

Conflicts:
	roles/kubernetes/master/tasks/kubeadm-cleanup-old-certs.yml

* Remove useless call to 'kubeadm version'

Signed-off-by: Etienne Champetier <[email protected]>
(cherry picked from commit a6e1f5e)

* Remove admin.conf removal

kubeadm is the default for a long time now,
and admin.conf is created by it, so let kubeadm handle it

Signed-off-by: Etienne Champetier <[email protected]>
(cherry picked from commit 280036f)

* Remove rotate_tokens logic

kubeadm never rotates sa.key/sa.pub, so there is no need to delete tokens/restart pods

Signed-off-by: Etienne Champetier <[email protected]>
(cherry picked from commit 8800b5c)

* Always backup both certs and kubeconfig

There are no reasons not to backup during upgrade

Signed-off-by: Etienne Champetier <[email protected]>
(cherry picked from commit 53e5ef6)

Conflicts:
	roles/kubernetes/master/tasks/kubeadm-backup.yml
	roles/kubernetes/master/tasks/kubeadm-certificate.yml

* Delete misnammed kubeadm-version.yml

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

Signed-off-by: Etienne Champetier <[email protected]>
(cherry picked from commit a9c97e5)

Conflicts:
	roles/kubernetes/master/tasks/kubeadm-version.yml

* Add privileged_without_host_devices support (kubernetes-sigs#7343)

When privileged is enabled for a container, all the `/dev/*` block
devices from the host are mounted into the guest. The
`privileged_without_host_devices` flag prevents host devices from
being passed to privileged containers.
