- If you're in a public cloud such as

[Google Cloud](https://cloud.google.com/sql/docs/postgres/),

[AWS](https://aws.amazon.com/rds/postgresql/),

[Azure](https://docs.microsoft.com/en-us/azure/postgresql/), or

[DigitalOcean](https://www.digitalocean.com/products/managed-databases-postgresql),

you can use the managed PostgreSQL offerings they provide. Make sure that

the PostgreSQL service is running and accessible from your cluster. It

should be in the same network, same project, etc.

- You can install Postgres manually on your cluster using the

[Bitnami PostgreSQL Helm chart](https://github.com/bitnami/charts/tree/master/bitnami/postgresql#readme). There are some

[helpful guides](https://phoenixnap.com/kb/postgresql-kubernetes) on the

internet that explain sensible configurations for this chart. Example:

```sh

# Install PostgreSQL

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

helm install coder-db bitnami/postgresql \

--namespace coder \

--set auth.username=coder \

--set auth.password=coder \

--set auth.database=coder \

--set persistence.size=10Gi

```

The cluster-internal DB URL for the above database is:

```

postgres://coder:coder@postgres-postgresql.coder.svc.cluster.local:5432/coder?sslmode=disable

```
