Deployment with Docker

**Warning**
|
|
|
|
Docker is evolving extremely fast, but it has still some rough edges here and there. Compose is currently (as of version 1.4)
|
|
not considered production ready. That means you won't be able to scale to multiple servers and you won't be able to run
|
|
zero downtime deployments out of the box. Consider all this as experimental until you understand all the implications
|
|
to run docker (with compose) on production.
|
|
|
|
**Run your app with docker-compose**
|
|
|
|
Prerequisites:
|
|
|
|
* docker (at least 1.10)
|
|
* docker-compose (at least 1.6)
|
|
|
|
Before you start, check out the `docker-compose.yml` file in the root of this project. This is where each component
|
|
of this application gets its configuration from. It consists of a `postgres` service that runs the database, `redis`
|
|
for caching, `nginx` as reverse proxy and last but not least the `django` application run by gunicorn.
|
|
{% if cookiecutter.use_celery == 'y' -%}
|
|
Since this application also runs Celery, there are two more services with a service called `celeryworker` that runs the
|
|
celery worker process and `celerybeat` that runs the celery beat process.
|
|
{% endif %}
|
|
|
|
|
|
All of these services except `redis` rely on environment variables set by you. There is an `env.example` file in the
|
|
root directory of this project as a starting point. Add your own variables to the file and rename it to `.env`. This
|
|
file won't be tracked by git by default so you'll have to make sure to use some other mechanism to copy your secret if
|
|
you are relying solely on git.
|
|
|
|
|
|
By default, the application is configured to listen on all interfaces on port 80. If you want to change that, open the
|
|
`docker-compose.yml` file and replace `0.0.0.0` with your own ip. If you are using `nginx-proxy`_ to run multiple
|
|
application stacks on one host, remove the port setting entirely and add `VIRTUAL_HOST={{cookiecutter.domain_name}}` to your env file.
|
|
This pass all incoming requests on `nginx-proxy`_ to the nginx service your application is using.
|
|
|
|
.. _nginx-proxy: https://github.com/jwilder/nginx-proxy
|
|
|
|
Postgres is saving its database files to the `postgres_data` volume by default. Change that if you wan't
|
|
something else and make sure to make backups since this is not done automatically.
|
|
|
|
To get started, pull your code from source control (don't forget the `.env` file) and change to your projects root
|
|
directory.
|
|
|
|
You'll need to build the stack first. To do that, run::
|
|
|
|
docker-compose build
|
|
|
|
Once this is ready, you can run it with::
|
|
|
|
docker-compose up
|
|
|
|
|
|
To run a migration, open up a second terminal and run::
|
|
|
|
docker-compose run django python manage.py migrate
|
|
|
|
To create a superuser, run::
|
|
|
|
docker-compose run django python manage.py createsuperuser
|
|
|
|
|
|
If you need a shell, run::
|
|
|
|
docker-compose run django python manage.py shell
|
|
|
|
To get an output of all running containers.
|
|
|
|
To check your logs, run::
|
|
|
|
docker-compose logs
|
|
|
|
If you want to scale your application, run::
|
|
|
|
docker-compose scale django=4
|
|
docker-compose scale celeryworker=2
|
|
|
|
|
|
**Don't run the scale command on postgres or celerybeat**
|
|
|
|
Once you are ready with your initial setup, you wan't to make sure that your application is run by a process manager to
|
|
survive reboots and auto restarts in case of an error. You can use the process manager you are most familiar with. All
|
|
it needs to do is to run `docker-compose up` in your projects root directory.
|
|
|
|
If you are using `supervisor`, you can use this file as a starting point::
|
|
|
|
[program:{{cookiecutter.project_slug}}]
|
|
command=docker-compose up
|
|
directory=/path/to/{{cookiecutter.project_slug}}
|
|
redirect_stderr=true
|
|
autostart=true
|
|
autorestart=true
|
|
priority=10
|
|
|
|
|
|
Place it in `/etc/supervisor/conf.d/{{cookiecutter.project_slug}}.conf` and run::
|
|
|
|
supervisorctl reread
|
|
supervisorctl start {{cookiecutter.project_slug}}
|
|
|
|
To get the status, run::
|
|
|
|
supervisorctl status
|
|
|
|
If you have errors, you can always check your stack with `docker-compose`. Switch to your projects root directory and run::
|
|
|
|
docker-compose ps
|
