Fixes #181

Issue - Docker compose fails locally with 2 errors

Issue #1:

Error response from daemon: Mounts denied The path /postgres-data is not shared from the host and is not known to Docker.

Solution:

Changing
volumes: - /postgres-data:/var/lib/postgresql/data
to
volumes: - ./postgres-data:/var/lib/postgresql/data

Issue #2:

cms-docker: Error P1001: Can't reach database server at 'db':'5432'
Please make sure your database server is running at db:5432

Solution:

• Add health check condition for db in depends_on to ensure docker-cms runs only after docker-db is up and ready.
• Add health check to postgres docker container
