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)
The current templating of kubevirt VirtualMachine relies on global
ansible variables, except for the group the nodes are meant to be in.
In order to have more flexibility (in particular, mixed OS cluster for
instances), expect now an abitrary dict to be passed to the template ;
this allows to embed directly in the nodes definition any variable used
by the template.
This allows a single source of truth for the virtual machines in a
kubevirt ci-run.
`etcd_member_name` should be correctly handled in kubespray-defaults for
testing the recover cases.
This leverage the Kubernetes GC to delete kubevirt VMs, by using
ownerReferences, with the CI pod running the playbook as the owner.
This concretely means that the control plane in our CI cluster will
delete the kubevirt VMs associated with a particular ci job as soon as
that pod job is deleted, which usually happens when the job terminates,
(barring errors, which will be addressed in the cluster directly)
Upgrade to kubevirt.io/v1 for the VirtualMachine manifests, since the
alpha version is deprecated.
* ci: redefine multinode to node-etcd-client
This should allow to catch several class of problem rather than just
one -> from network plugin such as calico or cilium talking directly to
the etcd.
* Dynamically define etcd host range
This has two benefits:
- We don't play the etcd role twice for no reason
- We have access to the whole cluster (if needed) to use things like
group_by.
