2021-02-03Change 'rke' role testing strategyBartek Grzybowski4-74/+4
So far Molecule framework setup allowed full rke cluster deployment in testing env but since rke cluster often fails to deploy in resource constrained CI environment this change switches testing strategy to only simulate 'rke up' operation. Change-Id: Ia221da6666d558e086cd24155f5bd81237d82388 Issue-ID: OOM-2665 Signed-off-by: Bartek Grzybowski <b.grzybowski@partner.samsung.com>
2020-01-10Limit resource footprint of rke role testsBartek Grzybowski1-1/+1
Number of kubernetes nodes created by rke role tests was limited to 1 - higher number caused resource exhaustion in CI worker (8gb memory limit). Verifier timeout was increased in routine where pod readiness is checked.

2019-06-03Add etcd group support to rke roleMichal Zegan2-1/+14
Etcd cluster is now placed in members of kubernetes-etcd group instead of kubernetes-node. Due to defaults, it means infra is the only etcd by default. Change-Id: Iae05a42442849e4a248d73c2d78f5e2b0eae7255 Issue-ID: OOM-1778 Signed-off-by: Michal Zegan <m.zegan@samsung.com>
2019-06-03Make rke to use new group structureMichal Zegan1-1/+1
Rke playbook/role is modified to take advantage of the new group structure. Namely, all members of kubernetes group are treated as cluster members independent of their role. The role itself is selected in cluster.yml.j2 template based on actual membership in either kubernetes-node or kubernetes-control-plane group.

2019-06-03Add molecule tests for rke roleMichal Zegan3-0/+83
This change adds molecule tests for the rke role, and modifies the rke role itself to be more idempotent/to pass linter. Note that this molecule test case uses a separate role to install docker in containers, that runs docker daemon inside of them instead of using host docker.
