![]() uses a named volume, "my_dbdata", for storing the database data using the volumes key.connects port 5432 inside Docker as port 54320 on the host machine using the ports key.sets the postgres superuser password to "my_password" using the environment key and the POSTGRES_PASSWORD environment variable.creates a container named "my_postgres" using the container_name key.uses the postgres:13 image from using the image key. ![]() sets up a service named "db" (this name can be used with docker-compose commands).sets the postgres superuser password to "my_password" using -e and the POSTGRES_PASSWORD environment variable.Ĭreate a new file docker-compose.yml: version: "3".uses the -d flag to run in the background.exposes port 54320 to the host using -p.uses a named volume, my_dbdata, to store postgres data.uses the official docker postgres 13 image.Install Docker ¶Īlternatively, you can install Docker using Homebrew: brew install homebrew/cask/docker OPTION 1: Run Postgres using a single Docker command ¶ Run a postgres container I also wrote some notes on Postgres and Homebrew here. Currently I use the Homebrew Postgres for work, and Postgres in Docker for personal projects. ![]() We use Docker extensively at work, so from a mental overhead point of view, it's something I wanted to learn anyways. Admittedly, I didn't know Homebrew well, but it was frustrating.) Disadvantages of Docker are it's another layer of abstraction to learn and interact with. (I previously had a problem where Homebrew upgraded Postgres when I didn't expect it to and my existing database became incompatible. ![]() Running in Docker allows keeping my database environment isolated from the rest of my system and allows running multiple versions and instances. These are my notes for running Postgres in a Docker container for use with a local Django or Rails development server running on the host machine (not in Docker).
