How to run it?
Copy these content into your docker-compose.yml file and then run the docker through docker-compose up or docker-compose up -d.

Configuration
It's better to update configuration based on your own environment. And follow the guide for postgres and dpage/pgadmin4.

Use it

1. after you run the command success, then you can open your browser and access http://localhost
2. login with the email and password you defined indpage/pgadmin4 in docker-compose.yml
3. connect the Postgres server with the host : postgres, username: postgres, password: empty

Thank you for this. I am using a similar setup, but I am not able to login to pgadmin. Seems it uses a default user and password I am not aware of, and ignores the one I specified in the environments.

I created a StackOverflow question here, in case you want to look at the details.
