`ha` layout consists of two etcd nodes, two masters and a single worker node,
with role intersection.
`scale` layout can be combined with above layouts. It includes 200 fake hosts
`scale` layout can be combined with above layouts (`ha-scale`, `separate-scale`). It includes 200 fake hosts
in the Ansible inventory. This helps test TLS certificate generation at scale
to prevent regressions and profile certain long-running tasks. These nodes are
never actually deployed, but certificates are generated for them.
Note, the canal network plugin deploys flannel as well plus calico policy controller.

The [CI Matrix](docs/ci.md) displays OS, Network Plugin and Container Manager tested.
The "Stage" means a build step of the build pipeline. The steps are ordered as `part1->part2->special`.
All tests are breakdown into 3 "stages" ("Stage" means a build step of the build pipeline) as follows:
- _unit_tests_: Linting, markdown, vagrant & terraform validation etc...
- _part1_: Molecule and AIO tests
- _part2_: Standard tests with different layouts and OS/Runtime/Network
- _part3_: Upgrade jobs, terraform jobs and recover control plane tests
- _special_: Other jobs (manuals)
The steps are ordered as `unit_tests->part1->part2->part3->special`.
