Placement Plugin

The rigdev.placement plugin adds placement configuration to the Deployment resource of your capsule. It can modify the nodeSelector and tolerations fields of the deployment. It has a requireTag bool config value. If set to true, the plugin will only run on capsules rigdev.placement/tag annotation matches the tag of the placement plugin. This also means the tag must be set on the plugin if requireTag is true.

Example

Config:

Helm values - Operator

config:
  pipeline:
    steps:
      - plugins:
          - plugin: rigdev.placement
            config: |
              nodeSelector:
                key1: value1
              tolerations:
                - key: some-key
                  value: some-value

The Deployment resource of the Capsule

kind: Deployment
...
spec:
  template:
    spec:
      nodeSelector:
        key2: value2
      tolerations:
        - key: some-other-key
          value: some-other-value
   ...

The resulting config of the Deployment is

kind: Deployment
...
spec:
  template:
    spec:
      nodeSelector:
        key1: value1
        key2: value2
      tolerations:
        - key: some-other-key
          value: some-other-value
        - key: some-key
          value: some-value
