@Marvin How can I use external postgres db installing with helm ?

To use an external PostgreSQL database when installing Prefect with Helm, you can follow these steps: 1. Add the Prefect Helm repository:

helm repo add prefect <https://prefecthq.github.io/prefect-helm>
    helm repo update

2. Create a namespace:

kubectl create namespace prefect

3. Create a Kubernetes secret for the PostgreSQL credentials:

kubectl create secret generic postgresql-credentials \
      --namespace=prefect \
      --from-literal=username=your_postgres_username \
      --from-literal=password=your_postgres_password

4. Customize the Helm chart values: Create a file named

values.yaml

with the following contents, replacing the placeholders with your actual PostgreSQL information:

postgresql:
      enabled: false  # Disable the default PostgreSQL installation
    externalDatabase:
      host: your_postgres_host
      port: your_postgres_port
      user: your_postgres_username
      password: your_postgres_password
      database: your_postgres_database

5. Deploy Prefect with the modified values file:

helm install my-prefect-release prefect/prefect-server -n prefect -f values.yaml
