+# Using Docker and Docker Compose to run OpenStreetMap
+
+Using [Docker](https://www.docker.com/) will allow you to install the OpenStreetMap application and all its dependencies in Docker images and then run them in containers, almost with a single command. You will need to install Docker and Docker Compose on your development machine:
+
+- [Install Docker](https://docs.docker.com/install/)
+- [Install Docker Compose](https://docs.docker.com/compose/install/)
+
+These instructions gloss over the precise details of the dependencies and their configuration but these can be found in full detail at [INSTALL.md](INSTALL.md).
+
+The first step is to fork/clone the repo to your local machine. The repository is reasonably large (~150MB) and it's unlikely that you need the full history. If you are happy to wait for it all to download, run:
+
+ git clone https://github.com/openstreetmap/openstreetmap-website.git
+
+To clone only the most recent version (~23MB), instead use a 'shallow clone':
+
+ git clone --depth=1 https://github.com/openstreetmap/openstreetmap-website.git
+
+Now change working directory to the `openstreetmap-website`:
+
+ cd openstreetmap-website
+
+### Storage setup
+
+ cp config/example.storage.yml config/storage.yml
+
+### Database
+
+ cp config/docker.database.yml config/database.yml
+
+### App configuration
+
+ cp config/settings.yml config/settings.local.yml
+
+### Installation
+
+In the root directory run:
+
+ docker-compose build
+
+Now if this is your first time running or you have removed cache this will take some time to complete. So grab tea/coffee and sit tight. Once the Docker images have finished building you can launch the images as containers.
+
+To launch the app run:
+
+ docker-compose up -d
+
+This will launch one Docker container for each 'service' specified in `docker-compose.yml` and run them in the background. There are two options for inspecting the logs of these running containers:
+
+- You can tail logs of a running container with a command like this: `docker-compose logs -f web` or `docker-compose logs -f db`.
+- Instead of running the containers in the background with the `-d` flag, you can launch the containers in the foreground with `docker-compose up`. The downside of this is that the logs of all the 'services' defined in `docker-compose.yml` will be intermingled. If you don't want this you can mix and match - for example, you can run the database in background with `docker-compose up -d db` and then run the Rails app in the foreground via `docker-compose up web`.
+
+### Migrations
+
+While the `db' service is running, open another terminal windows and run:
+
+ docker-compose run --rm web rake db:migrate
+
+### Node.js modules
+
+We use Yarn to manage the Node.js modules required for the project:
+
+ docker-compose run --rm web rake yarn:install
+
+Once these are complete you should be able to visit the app at http://localhost:3000
+
+If localhost does not work, you can use the IP address of the docker-machine.
+
+### Tests
+
+ docker-compose run --rm web rake test:db
+
+### Bash
+
+If you want to get into a web container and run specific commands you can fire up a throwaway container to run bash in via:
+
+ docker-compose run --rm web bash
+
+Alternatively, if you want to use the already-running `web` container then you can `exec` into it via:
+
+ docker-compose exec web bash
+
+Similarly, if you want to `exec` in the db container use:
+
+ docker-compose exec db bash
+
+### Populating the database
+
+This installation comes with no geographic data loaded. You can either create new data using one of the editors (Potlatch 2, iD, JOSM etc) or by loading an OSM extract.
+
+After installing but before creating any users or data, import an extract with [Osmosis](https://wiki.openstreetmap.org/wiki/Osmosis) and the `--write-apidb` task. The `web` container comes with `osmosis` pre-installed. So to populate data with a `.osm.pbf` use the following command:
+
+ docker-compose run --rm web osmosis \
+ --read-pbf /path/to/file.osm.pbf \
+ --write-apidb \
+ host="db" \
+ database="openstreetmap" \
+ user="openstreetmap" \
+ validateSchemaVersion="no"
