# Developing using Docker
|
||
|
|
|
||
|
|
Since Discourse runs in Docker, why not develop there? If you have Docker installed, you should be able to run Discourse directly from your source directory using a Discourse development container.
|
||
|
|
|
||
|
|
## Step-by-step
|
||
|
|
|
||
|
|
It should be as easy as (from your source root):
|
||
|
|
|
||
|
|
```sh
|
||
|
|
./bin/docker/boot_dev --init
|
||
|
|
# wait while:
|
||
|
|
# - dependencies are installed,
|
||
|
|
# - the database is migrated, and
|
||
|
|
# - an admin user is created (you'll need to interact with this)
|
||
|
|
./bin/docker/rails s
|
||
|
|
```
|
||
|
|
|
||
|
|
... then open a browser on http://localhost:3000 and _voila!_, you should see Discourse.
|
||
|
|
|
||
|
|
When you're done, you can kill the Docker container with:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
./bin/docker/shutdown_dev
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that data is persisted between invocations of the container in your source root `tmp/postgres` directory.
|
||
|
|
|
||
|
|
## Caveats
|
||
|
|
|
||
|
|
There seems to be an issue with the ember-data-source gem installed by default (2.3.0.beta.5). It's missing its `dist` directory. I've worked around this by acquiring that commit, building the distribution locally, and patching it into `/usr/local/lib/ruby/gems/2.3.0/gems/ember-data-source-2.3.0.beta.5` by hand. I _believe_ later versions of the gem fix this, but the very next version (2.3.0 proper) bumps the ember-source dependency up to 2.0, which Discourse isn't using yet.
|
||
|
|
|
||
|
|
You can get `boot_dev` to patch for you by passing `--patch local/path/to/ember-data-source/dist` on the command-line. You should only have to do this once (like `--init`).

## Other Notes
|
||
|
|
|

|
|
##### Where is the container image/Dockerfile defined?
|
||
|
|
|
||
|
|
The Dockerfile comes from [discourse/discourse_docker on GitHub](https://github.com/discourse/discourse_docker), in particular [image/discourse_dev](https://github.com/discourse/discourse_docker/tree/master/image/discourse_dev).
