* [etcd] Update etcd 3.5.x to 3.6.5
- Add hashes for etcd 3.6.5
- Remove etcd v2 backup task for etcd 3.6
The etcd 3.6 removes 'etcdctl backup' command with ETCDCTL_API=2
- Downgrade etcd to 3.5 in netchecker
The netchecker does not work with etcd 3.6 becaust it removes v2 API support (--enable-v2).
And netchekcer does not support v3 API.
* Fix: Change etcd config to clean up v2 store before upgrading etcd to 3.6
* Bump etcd to 3.6.8
- This solves issue #5721 & #5713 (dupes)
- Provide a cleaner default usage pattern for the download role
around etcd that supports 'host' and 'docker' properly
- Extract the 'etcdctl' as a separate task install piece and reuse it where
appropriate
- Update the kubeadm-etcd task to reflect the above change
* Fix recover-control-plane to work with etcd 3.3.x and add CI
* Set default values for testcase
* Add actual test jobs
* Attempt to satisty gitlab ci linter
* Fix ansible targets
* Set etcd_member_name as stated in the docs...
* Recovering from 0 masters is not supported yet
* Add other master to broken_kube-master group as well
* Increase number of retries to see if etcd needs more time to heal
* Make number of retries for ETCD loops configurable, increase it for recovery CI and document it
The current way to setup the etc cluster is messy and buggy.
- It checks for cluster is healthy before the cluster is even created.
- The unit files are started on handlers, not in the task, so you mess with "flush handlers".
- The join_member.yml is not used.
- etcd events cluster is not configured for kubeadm
- remove duplicate runs between running the role on etcd nodes and k8s nodes
* Adding yaml linter to ci check
* Minor linting fixes from yamllint
* Changing CI to install python pkgs from requirements.txt
- adding in a secondary requirements.txt for tests
- moving yamllint to tests requirements
