I tried the following the [Developing using Docker](https://github.com/discourse/discourse/tree/master/bin/docker) guide:

```plaintext
$ cd /tmp
$ git clone https://github.com/discourse/discourse.git
$ cd discourse
$ ./bin/docker/boot_dev --init

```

Realized that it is looking for `discourse/discourse_dev:latest` image which doesn’t exist in the DockerHub repository. So I decided to build it locally and tag accordingly:

```plaintext
$ cd /tmp
$ git clone https://github.com/discourse/discourse_docker.git
$ cd discourse_docker
$ docker build -t discourse/discourse_dev image/discourse_dev

```

It complained about missing template files and failed to build. So I looked at the corresponding Dockerfile to find out what files are being added then I copied them from the template directory:

```plaintext
$ cp templates/redis.template.yml templates/postgres.template.yml image/discourse_dev
$ docker build -t discourse/discourse_dev image/discourse_dev

```

Voila! Success! 🙂

Going back to the main discourse directory to setup the work environment:

```plaintext
$ cd /tmp/discourse
$ ./bin/docker/boot_dev --init

```

Container spun and gems bundled, but database migration failed:

```plaintext
Bundle complete! 98 Gemfile dependencies, 184 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.
Post-install message from certified:
IMPORTANT: Remember to use the included executable `certifed-update` regularly to keep your certificate bundle up to date.
Migrating database...

```

So, I decided to dive inside the running container and run the migrations manually:

```plaintext
$ docker exec -it discourse_dev bash
# cd src
# rake db:migrate

```

But the migrations did not succeed.

```plaintext
URGENT: could not connect to server: No such file or directory

	connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

```

From here I am not sure what else should I try.
