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
* rename ansible groups to use _ instead of -
k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating
Note: kube-node,k8s-cluster groups in upgrade CI
need clean-up after v2.16 is tagged
* ensure old groups are mapped to the new ones
* crio: add supported versions 1.20 and 1.21 and align default with k8s version
* cri-o: drop versions 1.17 and 1.18 from version matrix
* update note on cri-o version alignment
* calico: drop support for version 3.15
* drop check for calico version >= 3.3, we are at 3.16 minimum now
* we moved to calico 3.16+ so we can default to /opt/cni/bin/install
* AlmaLinux: ansible>2.9.19 is needed to know about AlmaLinux
* AlmaLinux: identify as a centos derrivative
* AlmaLinux: add AlmaLinux to checks for CentOS
* Use ansible_os_family to compare family and not distribution
As the official document[1], the parameter keepcache should be
'0' or '1' as string. To avoid the following warning message,
this fixes the parameter value:
[WARNING]: The value False (type bool) in a string field was
converted to u'False' (type string). If this does not look
like what you expect, quote the entire value to ensure it
does not change.

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'}) =>
{"ansible_loop_var": "item", "changed": false, "item": {"file": "cilium-secret.yml", "name": "cilium", "type": "secret",
"when": "cilium_ipsec_enabled"},"msg": "AnsibleUndefinedVariable: 'cilium_ipsec_key' is undefined"}
Moving the when condition from the item level to the task level solved
the issue.
* Add KubeSchedulerConfiguration for k8s 1.19 and up
With release of version 1.19.0 of kubernetes KubeSchedulerConfiguration
was graduated to beta. It allows to extend different stages of
scheduling with profiles. Such effect is achieved by using plugins and
extensions.
This patch adds KubeSchedulerConfiguration for versions 1.19 and later.
Configuration is set to k8s defaults or to kubespray vars. Moving those
defaults to new vars will be done in following patch.

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
'changed' and bounces systemd-resolved unneccesarily, even if there was no
actual modification of /etc/systemd/resolved.conf.
