Initialize database setup script

[johngrantdev]

For context I'm using the website template with postgres.

I would like to create a docker image from the dockerfile eg. docker build -t project-name . I found that during the build process it tries to make a database connection. If a valid database is not supplied then the build will fail.

I don't believe this is ideal behaviour as it creates a dependency in building the project and can make building challenging when also using postgres in a container.
eg.

• A postgres container needs to be running before the build process, if you build with docker-compose then you cannot specify the database in the same compose file as the payload app as the build process happens before any other containers are started even if the container dependency is defined.
• If you use the docker container name as the domain for the database this is not accessible from the build process, so you would need to manually set the docker ip address in the enviroment.
