phoenix-photo-tagger

Steps taken to set up project initially

Initially, only the docker-compose.yml and Dockerfile exist.
Run docker-compose run --build app bash to build the image, run the container, and open a bash shell in the container.
Run mix phx.new . --app phoenix_photo_tagger --no-live to create a new Phoenix project.
Edit database hostname and http ip in config/dev.exs to get working in docker container.
Run mix ecto.create to setup connection to database.
Run mix local.hex --force to initialize package manager.
Exit the docker container, and run sudo chown -R $USER:$USER ./app to change ownership of the files by scripts run in docker (which runs as root by default). This allows saving the files in vscode.
To run further mix commands in server (like ecto cmds), run docker-compose run --user $(id -u):$(id -g) app bash.
