# Node Layouts
|
|
|
|
There are four node layout types: `default`, `separate`, `ha`, and `scale`.
|
|
|
|
`default` is a non-HA two nodes setup with one separate `kube-node`
|
|
and the `etcd` group merged with the `kube-master`.
|
|
|
|
`separate` layout is when there is only node of each type, which includes
|
|
a kube-master, kube-node, and etcd cluster member.
|
|
|
|
`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
|
|
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 "Stage" means a build step of the build pipeline. The steps are ordered as `part1->part2->special`.
