# Install postgres
helm repo add bitnami https://charts.bitnami.com/bitnami

# Documentation and source of the used chart with all configuration parameters:
# https://artifacthub.io/packages/helm/bitnami/postgresql
# https://github.com/helm/charts/tree/master/stable/postgresql

# The postgresql helm chart requires the cluster to provide a PersistentVolume
# and places a PersisentVolumeClaim for this.
# Ensure that the cluster provides PersistentVolumes:

if kubectl get PersistentVolume -o json
   | jq -e '.items | .[].status | select(.phase == "Bound")' ; then
    echo "Ok found at least one PersistentVolume"
else
    echo "The postgresql helm chart has a PersistentVolumeClaim (PVC)."
    echo "The cluster needs to provide at one PersistentVolume (PV) for this."
    echo "For information how to create a PersistentVolume, see:"
    echo "https://github.com/felipecruz91/k8s-postgresql-persistent-volume#create-persistent-volume"
    exit 5
fi

# Note: The chart mounts the PV at persistence.mountPath,
# which defaults to /bitnami/postgresql and creates a directory /data in it.
# If it has no permission to create it, this error happens:
# mkdir: cannot create directory ‘/bitnami/postgresql/data’: Permission denied

# Adding --set volumePermissions.enabled=true helps:
