You must have cert-manager and the Postgres Operator in place before you can install MSR using the offline method.

To install cert-manager:


The cert-manager version must be 1.7.2 or later.

  1. Run the following helm install command:

    helm install cert-manager jetstack/cert-manager \
    --version 1.7.2 \
    --set installCRDs=true \
    -f my_certmanager_values.yaml
  2. Verify that cert-manager is in the Running state:

    kubectl get pods

    If any of the cert-manager Pods are not in the Running state, run kubectl describe on each Pod:

    kubectl describe <cert-manager-pod-name>


    To troubleshoot the issues that present in the kubectl describe command output, refer to Troubleshooting in the official cert-manager documentation.

To install Postgres Operator:


The Postgres Operator version must be 1.9.0. 1

  1. Run the following helm install command, including spilo_* parameters:

    helm install postgres-operator postgres-operator/postgres-operator \
    --version <version> \
    --set configKubernetes.spilo_runasuser=101 \
    --set configKubernetes.spilo_runasgroup=103 \
    --set configKubernetes.spilo_fsgroup=103 \
    -f my_postgres_values.yaml
  2. Verify that Postgres Operator is in the Running state:

    kubectl get pods

    To troubleshoot a failing Postgres Operator Pod, run the following command:

    kubectl describe <postgres-operator-pod-name>

    Review the Pod logs for more detailed results:

    kubectl logs <postgres-operator-pod-name>


By default, MSR uses the persistent volume claims detailed in Volumes.

If you have a pre-existing PersistentVolume that contains image blob data that you intend to use with a new instance of MSR, you can use Helm to provide the new instance with the name of the associated PersistentVolumeClaim:


This setting indicates the <release-name> PVC referred to in Volumes.


Postgres Operator up through 1.8.2 uses the PodDisruptionBudget policy/v1beta1 Kubernetes API, which is no longer served as of Kubernetes 1.25. As such, various features of MSR may not function properly if Postgres Operator 1.8.2 or earlier is installed alongside MSR on Kube v1.25 or later.
