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

Previous check for presence of NM assumed "systemctl show

the case anymore with recent Flatcar Container Linux.
This new check also checks the activeness of network manager, as

If crictl (and docker) binaries are deployed to the directories
that are not in standard PATH (e.g. /usr/local/bin), it is required
to specify full path to the binaries.
calico PODs are first started and then in a handler killed and
restarted for no reason, nothing has changed.
By using the existing variable 'calico_cni_config' (only defined when
calico has already started) the restart can be skipped.

* Update template with more cleaner expression
flannel, ovn and multus network plugins did not support all taint keys. This
update changes the tolerations to support them all.
According to the documentation:
```
There are two special cases: An empty key with operator Exists matches all keys,
values and effects which means this will tolerate everything. An empty effect matches
all effects with key key.
```
Usage of the empty `key` and `effect` ensures the network plugin daemonset will
be deployed on every nodes (ex: in case of custom taints, or NoExecute effect)
Since weave 2.5.1, `NoExecute` taint effect is no more supported,
this changes the daemonset tolerations to change this behavior.
Also remove the toleration key `CriticalAddonsOnly` not required anymore.
* added required permissions for querying endpointslice resources
* copy-pasted role permissions from cilium install manifests
* bumped cilium version to v1.7.2
* Support configuring the insert mode
Defaults to the upstream default https://docs.projectcalico.org/v3.9/reference/felix/configuration
so nothing should change for existing deployments.
This allows coexistence with other firewall management technologies.
* Add a note to the sample config
* Added in code to allow control over pull policy for local path provisioner
* change to imagePullPolicy to use globally used variable k8s_image_pull_policy
* removed unusued variable from defaults
* updated contiv-etcd and cinder-csi-controllerplugin to use k8s_image_pull_policy variable
Raises limit from 100 to 300 because the default is far too low
and the pod can handle 300 with the given resources.

Initially this was to fix a mis-indented approvers key. However, it turns
out that 'oilbeater' is not a member of kubernetes-sigs nor
kubernetes-incubator (the org this repo was migrated from). Thus this
OWNERS file is failing prow's validation check.
As a workaround I've opted to move them to emeritus_approver, which
isn't valiated and can be used as a hint for other approvers in this
repo
Cleaned up deprecated APIs:
apps/v1beta1
apps/v1beta2
extensions/v1beta1 for ds,deploy,rs
Add workaround for deploying helm using incompatible

settings, thus no-good to ab-use it to 'none')

Before, Nodes tainted with NoExecute policy did not have calico/weave Pod.
Network pod should run on all nodes whatever happens on a specific node.
Also always set the Pods to be critical.
