Helm chart configuration

Pelagia Helm chart contains multiple options to configure the Pelagia setup and prepare an environment for deployment.

For the complete list of available options, refer to values.yaml.

Custom images and settings

You can specify custom images for testing environments. Ceph images are derived from the cephRelease value. The following example illustrates available Ceph images based on the Ceph release:

images:
  ceph:
    repository: pelagia/ceph
    tag:
      latest: &latestImageCeph v20.2.1-3.release
      squid: v19.2.3-25.cve
      tentacle: *latestImageCeph

Also, you can specify custom settings for dependency charts, such as Rook, snapshot controller, and Ceph CSI operator if they are installed by the Pelagia chart. For example:

ceph-csi-operator:
  csiOperatorConfig:
    placement:
      tolerations:
      - effect: NoSchedule
        key: node-role.kubernetes.io/controlplane
        operator: Exists
rook:
  rookConfig:
    csiCephFsEnabled: false
    csiPlacement:
      tolerations:
        csiplugin: |
        - effect: NoSchedule
          key: node-role.kubernetes.io/controlplane
          operator: Exists
snapshot-controller:
  snapshotControllerConfig:
    nodeSelector:
      disktype: ssd
