.. 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)
|
||||
* Docker (at least 1.10)
|
||||
* Docker Compose (at least 1.6)
|
||||
|
||||
Understand the Compose Setup
|
||||
--------------------------------
|
||||
|
||||
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 %}
|
||||
of this application gets its configuration from. Notice how it provides configuration for these services:
|
||||
|
||||
* `postgres` service that runs the database
|
||||
* `redis` for caching
|
||||
* `nginx` as reverse proxy
|
||||
* `django` is the Django project run by gunicorn
|
||||
|
||||
All of these services except `redis` rely on environment variables set by you. There is an `env.example` file in the
|
||||
If you chose the `use_celery` option, there are two more services:
|
||||
|
||||
* `celeryworker` which runs the celery worker process
|
||||
* `celerybeat` which runs the celery beat process
|
||||
|
||||
If you chose the `use_letsencrypt` option, you also have:
|
||||
|
||||
* `certbot` which keeps your certs from letsencrypt up-to-date
|
||||
|
||||
Populate .env With Your Environment Variables
|
||||
---------------------------------------------
|
||||
|
||||
Some of these services 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.
|
||||
|
||||
Optional: nginx-proxy Setup
|
||||
---------------------------
|
||||
|
||||
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.
|
||||
`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=example.com` to your env file. Here, replace example.com with the value you entered for `domain_name`.
|
||||
|
||||
This pass all incoming requests on `nginx-proxy`_ to the nginx service your application is using.

||||

||||

|
||||
|
||||
Optional: Postgres Data Volume Modifications
|
||||
---------------------------------------------
|
||||
|
||||
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.
|
||||
|
||||
Run your app with docker-compose
|
||||
--------------------------------
|
||||
|
||||
To get started, pull your code from source control (don't forget the `.env` file) and change to your projects root
|
||||
directory.
