MSR 4.0 reaches End of Life (EOL) on July 17, 2026. To maintain support and receive updates, Mirantis recommends upgrading to the latest version.

Install and set up PostgreSQL

1. Add the Bitnami repository:

helm repo add bitnami https://charts.bitnami.com/bitnami

1. Create and populate postgresql-values.yaml file:

   primary:
     persistence:
       enabled: true
       size: 10Gi
       storageClass: "<nameofstorageclass>"
     postgresql:
       password: "support"
       replicaCount: 3
       initdbScripts:
         create_databases.sh: |
           #!/bin/bash
           export PGPASSWORD=$(cat /opt/bitnami/postgresql/secrets/password)
           psql -U postgres -c "CREATE DATABASE harbor_core" && psql -U postgres -c "CREATE DATABASE clair" && psql -U postgres -c "CREATE DATABASE notary_signer" && psql -U postgres -c "CREATE DATABASE notary_server"
       resources:
         limits:
           cpu: 500m
           memory: 512Mi
         requests:
           cpu: 100m
           memory: 256Mi

1. Install HA PostgreSQL with a helm install command:

helm install postgresql bitnami/postgresql-ha -f postgresql-values.yaml

1. Obtain the PostgreSQL password:

export POSTGRES_PASSWORD=$(kubectl get secret --namespace default postgresql-postgresql-ha-postgresql -o jsonpath="{.data.password}" | base64 -d)
echo $POSTGRES_PASSWORD

1. Login to PostgreSQL:

kubectl run postgresql-postgresql-ha-client --rm --tty -i --restart='Never' --namespace default --image docker.io/bitnami/postgresql-repmgr:16.4.0-debian-12-r12 --env="PGPASSWORD=$POSTGRES_PASSWORD"  \
--command -- psql -h postgresql-postgresql-ha-pgpool -p 5432 -U postgres -d postgres

1. Find the pool service and port:

kubectl get service

Example output:

postgresql-postgresql-ha-pgpool                ClusterIP   10.96.40.233    <none>        5432/TCP
