Deploy Postgres from a Helm chart

Learn how to deploy Postgres from the Bitnami Helm chart. After you deploy Postgres on your cluster, you can register the application with Astra.

Postgres is a validated app for Astra. Learn the difference between Validated and Standard apps.

Applications deployed from Google Marketplace have not been validated. Some users report issues with discovery and/or backup with Google Marketplace deployments of Postgres, MariaDB, and MySQL.


  • A fresh GKE cluster which has been added to Astra.

  • Updated versions of Helm (version 3.2+) and Kubectl installed.

  • Kubeconfig configured using the gcloud tool with a command like gcloud container clusters get-credentials my-cluster-name

Install Postgres

Two important notes on this process:

  • You must deploy your app after the cluster is added to Astra, not before.

  • You must deploy the Helm chart in a namespace other than the default.

Add the Bitnami chart repo:

helm repo add bitnami

Deploy Postgres with the command:

kubectl create namespace testdb && helm install bitnami/postgresql --namespace testdb --set postgresqlPassword=U9dH9HT4pWS,postgresqlDatabase=test_db --generate-name

This does the following:

  • Creates the testdb namespace.

  • Deploys Postgres on the testdb namespace.

  • Creates a database named test_db

  • Creates a user test_db_user with password U9dH9HT4pWS

This method of setting the password at deployment is insecure. We do not recommend this for a production environment.

After the pods are online, you can manage the app with Astra. Astra allows you to manage an app at the namespace level or using a helm label
