While running Ghostwriter using
local.yml, you can make changes on the fly without needing to run any Docker commands. Django smartly restarts the server when it detects a file change. Also, the local deployment mounts Ghostwriter's directory on your host, so changes to the code (Python or templates) will be live once the file is saved.
build, stop, rm, up -d commands need to be run only if you add a new library or if you add a new task to tasks.py (only after initially adding the new function, not each time you change the function).
docker-compose -f local.yml stop; docker-compose -f local.yml rm -f; docker-compose -f local.yml build; docker-compose -f local.yml up -d
If a model is added, updated, or deleted, the model changes must be migrated before they will go live in the application. This is accomplished using the Docker
run command to execute the usual Django migration commands with manage.py:
docker-compose -f local.yml run --rm django python manage.py makemigrations
docker-compose -f local.yml run --rm django python manage.py migrate
Most errors will be displayed in your web browser thanks to the verbose error output configured for local deployments.
Of course, there will be no visible output in your browser if an error prevents Django from starting the server. To view logging output from Redis, PostgreSQL, and Django, use the Docker
docker-compose -f local.yml logsdocker-compose -f local.yml logs djangodocker-compose -f local.yml logs queuedocker-compose -f local.yml logs redisdocker-compose -f local.yml logs postgres
If you break something or want to start from scratch, stop all of your containers and run these two commands:
docker system prune -adocker volume rm -f $(docker volume ls)
The first command will remove all stopped containers. If you only need to re-build, you can stop there and build your containers again.
The second command deletes all volumes. Thie volumes hold your data (e.g., the database and files). If you leave them intact, your new container will launch ready to use with your existing data. You'll need to delete the volumes to get a true fresh start.
