Before "5ca23e3bf (Changed to use first_kube_control_plane to parse
kubeadm_certificate_key (#11875), 2025-01-14)", kubespray would have
problem adding new control planes when the order of the nodes in kubectl
output and the ansible inventory were not the same.
But the underlying problem is that the operation is fundamentally
something that should be done only once, and recorded for all host in
play.
Since `register` and `sef_fact` when used with `run_once` set the
variable for all the hosts, use it. Also allows to use the variable
directly instead of relying on hostvars to make the task more readable.
Most variables should have a default instead of relying on the default
filter.
(Note that the variable is misnomed, this should be certs and not keys,
but it's not worth breaking compat).
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.
* control-plane: fix first_kube_control_plane delegation with kube_override_hostname
When kube_override_hostname is configured, the node names reported by
`kubectl get nodes` differ from the inventory_hostname known to Ansible.
This causes delegation failures in subsequent tasks since Ansible cannot
resolve the hostname from kubectl output to an inventory host.

* control-plane: remove fragile first_control_plane selection logic
Current implementation breaks with kube_override_hostname and has
multiple edge cases. Drop until proper kubectl-based node lookup
can be implemented.

This should make 'no space left on device' problems easier to handle
Use /tmp/releases as local_release_dir CI created machine, while keeping
the same folder on the runner (needed for gitlab-ci runner pods)
* CI: Try a full ssh connection on hosts instead of only checking the port
If we only try the port, we can try to connect in the playbook which is
executed next even though the managed node has not yet completed it's
boot-up sequence ("System is booting up. Unprivileged users are not
permitted to log in yet. Please come back later. For technical details,
see pam_nologin(8).")
This does not account for python-less hosts, but we don't use those in
CI anyway (for now, at least).
* CI: Remove connection method override when creating VMs
This prevented wait_for_connection to work correctly by hijacking the
connection to localhost, thus bypassing the connection check.
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
* Remove etcd member by peerURLs
The way to obtain the IP of a particular member is convoluted and depend
on multiple variables. The match is also textual and it's not clear
against what we're matching
It's also broken for etcd member which are not also Kubernetes nodes,
because the "Lookup node IP in kubernetes" task will fail and abort the
play.
Instead, match against 'peerURLs', which does not need new variable, and
use json output.
* Add testcase for etcd removal on external etcd
* do not merge
* fixup! Remove etcd member by peerURLs
* fixup! Remove etcd member by peerURLs
