There is litte reason to share an ssh key common to all CI jobs, so
generate one for each on the fly.
Also use plain-text cloud-init config instead of base64 for readability
To work with molecule, we need to use the name provided by molecule_yml
in inventory.
Inject the name in the VirtualMachineInstance (with a default to handle
non-molecule scenario) and get it back as part of inventory).
Account for no ansible groups
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.
VirtualMachineInstance resources sometimes temporarily loose their
IP (at least as far as the kubevirt controllers can see).
See https://github.com/kubevirt/kubevirt/issues/12698 for the upstream
bug.
This does not seems to affect actual connection (if it did, our current
CI would not work).
However, our CI execute multiple playbooks, and in particular:
1. The provisioning playbook (which checks that the IPs have been
provisioned by querying the K8S API)
2. Kubespray itself
If any of the VirtualMachineInstance looses its IP between after 1
checked for it, and before 2 starts, the dynamic inventory (which is
invoked when the playbook is launched by ansible-playbook) will not have
an ip for that host, and will try to use the name for ssh, which of
course will not work.
Instead, when we have a valid state during provisioning (all IPs
presents), use it to construct a static inventory which will be used for
the rest of the CI run.
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.
VMI in Kubevirt are the abstraction below VirtualMachine.
- We don't really need the extra abstraction of VirtualMachine objects
- Convert the waiting for VMs ip address to use kubernetes.core.k8s_info
and no shell pipeline
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: reduce VM resources requests to improve scheduling
* CI: Reduce default jobs; add labels(ci-full/extended) to run more test
* CI: use jobs dependencies instead of stages
* precommit one-job
* CI: Use Kubevirt VM to run Molecule and Vagrant jobs
