** Please be patient while the chart is being deployed **

PostgreSQL can be accessed via port 5432 on the following DNS names from within your cluster:

    test-postgres-postgresql.default.svc.cluster.local - Read/Write connection

To get the password for "postgres" run:

    export POSTGRES_PASSWORD=$(kubectl get secret --namespace default test-postgres-postgresql -o jsonpath="{.data.postgres-password}" | base64 -d)

To connect to your database run the following command:

    kubectl run test-postgres-postgresql-client --rm --tty -i --restart='Never' --namespace default --image docker.io/bitnami/postgresql:14.5.0-debian-11-r14 --env="PGPASSWORD=$POSTGRES_PASSWORD" \
      --command -- psql --host test-postgres-postgresql -U postgres -d testdb -p 5432

    > NOTE: If you access the container using bash, make sure that you execute "/opt/bitnami/scripts/postgresql/entrypoint.sh /bin/bash" in order to avoid the error "psql: local user with ID 1001} does not exist"

To connect to your database from outside the cluster execute the following commands:

    kubectl port-forward --namespace default svc/test-postgres-postgresql 5432:5432 &
    PGPASSWORD="$POSTGRES_PASSWORD" psql --host 127.0.0.1 -U postgres -d testdb -p 5432
