When loadbalancer_apiserver_localhost is enabled, Calico falls back to the
Kubernetes service IP because the kubernetes-services-endpoint ConfigMap is
empty. CNI then fails to reach the API server even though an nginx proxy is
listening on localhost.
Update kube_apiserver_global_endpoint to always reference the localhost load
balancer (respecting the configured port) and populate the ConfigMap for both
eBPF and localhost LB modes.
Add missing RBAC permissions for Calico apiserver to function correctly
with Kubernetes 1.33+
Changes:
1. Add K8s 1.33 ValidatingAdmissionPolicy resources to calico-webhook-reader
- validatingadmissionpolicies
- validatingadmissionpolicybindings
Kubernetes 1.33 introduced ValidatingAdmissionPolicy resources (KEP-3488)
that require explicit RBAC permissions. Without these changes, Calico
apiserver on k8s 1.33+ will not work and needless errors are logged
Upstream calico isn't doing that, and:
- this can cause throttling
- the cpu needed by calico is very cluster / workload dependent
- missing cpu limits will not starve other pods (unlike missing memory
requests), because the kernel scheduler will still gives priority to
other process in pods not exceeding their requests
* make calico api server manifest backward compatible with version older than 3.27.3
Add 3.28.1 checksums
Add 3.28.0 checksums
Change default version to 3.27.3
* change default calico version to 3.28.1
* Set mount type to DirectoryOrCreate for hostPath needed by Calico
* Disable control plane allocating podCIDR for nodes when using calico
Calico does not use the .spec.podCIDR field for its IP address
management.
Furthermore, it can false positives from the kube controller manager if
kube_network_node_prefix and calico_pool_blocksize are unaligned, which
is the case with the default shipped by kubespray.
If the subnets obtained from using kube_network_node_prefix are bigger,
this would result at some point in the control plane thinking it does
not have subnets left for a new node, while calico will work without
problems.
Explicitely set a default value of false for calico_ipam_host_local to
facilitate its use in templates.
* Don't default to kube_network_node_prefix for calico_pool_blocksize
They have different semantics: kube_network_node_prefix is intended to
be the size of the subnet for all pods on a node, while there can be
more than on calico block of the specified size (they are allocated on
demand).
Besides, this commit does not actually change anything, because the
current code is buggy: we don't ever default to
kube_network_node_prefix, since the variable is defined in the role
defaults.
* Migrate node-role.kubernetes.io/master to node-role.kubernetes.io/control-plane
* Migrate node-role.kubernetes.io/master to node-role.kubernetes.io/control-plane
* Migrate node-role.kubernetes.io/master to node-role.kubernetes.io/control-plane
This commit removes the variable `use_localhost_as_kubeapi_loadbalancer`
and rather detects that we are in a situation where we can use the
localhost apiserver loadbalancer (meaning that we use the localhost load
balancer and that the same ports are used for both the load balancer and
the kube-apiserver).
This also cleanups the calico code to use `kube_apiserver_global_endpoint`
rather than implementing the same logic all over again.

It seems that PR #8839 broke `calico_datastore: etcd` when it removed ipamconfig support for etcd mode.
This PR fixes some failing tasks when `calico_datastore == etcd`, but it does not restore ipamconfig support for calico in etcd mode. If someone wants to restore ipamconfig support for `calico_datastore: etcd` please submit a follow up PR for that.
* Allow disabling calico CNI logs with calico_cni_log_file_path
Calico CNI logs up to 1G if it log a lot with current default settings:
log_file_max_size 100 Max file size in MB log files can reach before they are rotated.
log_file_max_age 30 Max age in days that old log files will be kept on the host before they are removed.
log_file_max_count 10 Max number of rotated log files allowed on the host before they are cleaned up.
See https://projectcalico.docs.tigera.io/reference/cni-plugin/configuration#logging
To save disk space, make the path configurable and allow disabling this log by setting
`calico_cni_log_file_path: false`
* Fix markdown
* Update roles/network_plugin/canal/templates/cni-canal.conflist.j2
