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.
* 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
* 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
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.
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.
This replaces kube-master with kube_control_plane because of [1]:
The Kubernetes project is moving away from wording that is
considered offensive. A new working group WG Naming was created
to track this work, and the word "master" was declared as offensive.
A proposal was formalized for replacing the word "master" with
"control plane". This means it should be removed from source code,
documentation, and user-facing configuration from Kubernetes and
its sub-projects.
NOTE: The reason why this changes it to kube_control_plane not
kube-control-plane is for valid group names on ansible.

* Download Calico KDD CRDs
* Replace kustomize with lineinfile and use ansible assemble module
* Replace find+lineinfile by sed in shell module to avoid nested loop
* add condition on sed
* use block for kdd tasks + remove supernumerary kdd manifest apply in start "Start Calico resources"
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

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)'

Previous check for presence of NM assumed "systemctl show
NetworkManager" would exit with a nonzero status code, which seems not
the case anymore with recent Flatcar Container Linux.
This new check also checks the activeness of network manager, as
`is-active` implies presence.

If some settings were changed from the default but not commited into an inventory repo,
we risk breaking the cluster / cause downtime, so add some extra checks

We are currently setting the IP variable to hostIP,
Before https://github.com/projectcalico/node/pull/593 (not yet released)
Calico interpret that as hostIP/32
Using 'can-reach' we get the future behavior
This fixes vxlan and IPIP CrossSubnet modes
