Upgrade Pelagia Guide#

This section provides instructions on how to upgrade Pelagia on an existing Kubernetes cluster.

Upgrade chart#

To upgrade Pelagia, use a new Helm chart version provided in the repository:

helm upgrade --install pelagia-ceph oci://registry.mirantis.com/pelagia/pelagia-ceph --version <new-version> -n pelagia

This command upgrades Pelagia controllers in the pelagia namespace.

Besides its own controllers, Pelagia can deliver updated Rook and Ceph manifests along with images. If cephRelease is not pinned in Pelagia values, Pelagia will automatically update a Ceph version if a new version is available.

To pin the Ceph version, specify it in the cephRelease field of the Pelagia values file. For example:

helm upgrade --install pelagia-ceph oci://registry.mirantis.com/pelagia/pelagia-ceph --version <new-version> -n pelagia --set cephRelease=squid

However, Mirantis does not recommend pinning the Ceph version to ensure you obtain important updates and bug fixes.
