Environment VariablesĬreate a new folder to store environment variables in the project root called. To simplify things, the web, celery_worker, celery_beat, and flower services will all use the same Dockerfile. Review the web, db, and redis services on your own, taking note of the comments. celery_beat is the Celery beat process for scheduled tasks.

celery_worker is the Celery worker process.

redis is the Redis service, which will be used as the Celery message broker and result backend.

Version : '3.8' services : web : build : context. Start by adding a docker-compose.yml file to the project root: This above config structure is based on the config found in the cookiecutter-django project, which is clean and easy to maintain. The "compose" folder holds configuration files, shell scripts, and the associated Dockerfiles for each environment. The above file structure uses two such files: One for development and the other for production - docker-compose.yml and, respectively. With Docker Compose, you describe the desired end state of you environment using a declarative syntax in a docker-compose.yml file.

Linux users will have to download and install them separately.ĭon't create the new files and folders just yet we'll create them throughout the remainder of the chapter.

If you're on a Mac or Windows machine, Docker Desktop will install both Docker and Docker Compose. Start by downloading and installing Docker if you haven't already done so. So, you won't have to mess around with a virtual environment or install tools like Postgres and Redis on your local OS.

#Why does docker for mac have an old compose version portable#

Docker, in general, allows us to create isolated, reproducible, and portable development environments.

With Docker Compose, we can easily create different configurations for both Django and Celery all from a single YAML file. The Celery config is currently tied to our Django app's config.

Docker Compose will also simplify configuration.

Instead of having to run each process (e.g., Django, Celery worker, Celery beat, Flower, Redis, Postgres, etc.) manually, each from a different terminal window, after we containerize each service, Docker Compose enables us to manage and run the containers using a single command.

Before we do that though, let's look at the why: Why should we serve up our development environment in Docker containers with Docker Compose? Well, in this chapter, we'll take this a step further and containerize our entire infrastructure to simplify development. $ docker run -p 6379:6379 -name some-redis -d redis
