Docker-Compose | Dockerizing pgAdmin and Postgres - Volumes and Custom Network IP

Welcome to another Docker-Compose tutorial. The Windows platform does support PostgreSQL, but it can be much more convenient to install Postgres and manage PostgreSQL with pgAdmin in containers. In this tutorial we create a docker-compose file to configure Postgres and pgAdmin allowing any other application, in this tutorial Django to connect to it. We go the extra step of configuring the network, assigning static IP addressed to the containers.

Hey, thanks for the awesome tutorial!
Maybe someone finds this useful: if you have a running postgres application on your machine, trying to run migrations with django might result in a weird error saying that the "test_db" does not exist even though you might have the docker container running and are accessing the db through pgadmin on port 5050.

[@veryacademy]

Thanks for the tip!

In addition to Echoes1265 comment, just go to task manager and end all postgresql tasks on your pc.

How can I find the other videos in this series?

[@ramiroramos8949]

What is the best way to configure environment variables for this case? Thanks for the video, this was exactly what I was looking for

[@veryacademy]

Hi Ramiro - first and foremost. This type of setup is for local development only - it is not recommended you use Docker for Postgres in production. Your question has a few answers, sorry if that was not applicable or if I don't answer your question.
This should be of use:
From: hub.docker.com/_/postgres
Docker Secrets
As an alternative to passing sensitive information via environment variables, _FILE may be appended to some of the previously listed environment variables, causing the initialization script to load the values for those variables from files present in the container. In particular, this can be used to load passwords from Docker secrets stored in /run/secrets/ files. For example:
$ docker run --name some-postgres -e POSTGRES_PASSWORD_FILE=/run/secrets/postgres-passwd -d postgres
Currently, this is only supported for POSTGRES_INITDB_ARGS, POSTGRES_PASSWORD, POSTGRES_USER, and POSTGRES_DB.

Please make a video on how to learn new topic. Like read docs, build project after reading docs.
