This chart deploys PostgreSQL on Spin. Update the placeholders in values_template.yaml, or use the helper script to generate values.yaml.

• kubectl and helm installed
• Access to a Spin namespace and its kubeconfig

See tls-acme/README.md for installation steps for kubectl/helm and kubeconfig.

1. Edit postgresql/prepare-values.sh with your settings.
2. Generate a rendered values file:

./prepare-values.sh

This writes values.yaml (or a custom path if you pass one).

cd postgresql
./prepare-values.sh
helm lint .
helm install -n <namespace> <release-name> .

helm install -n <namespace> <release-name> .

If your cluster requires LoadBalancer-specific annotations or a fixed IP, set them under loadBalancer in values.yaml. For example, Harvester DHCP-based address allocation can require:

loadBalancer:
  annotations:
    cloudprovider.harvesterhci.io/ipam: dhcp

helm upgrade -n <namespace> <release-name> .
helm uninstall -n <namespace> <release-name>

• Persistent volume size is controlled by persistentVolumeClaims.<deployment_name>.size (where deployment_name defaults to psql in prepare-values.sh).
• Liveness and readiness probes use pg_isready with the configured database name and user.
