# Using Docker and Docker Compose for Development and Testing
-These instructions are designed for setting up The Rails Port for development and testing using [Docker](https://www.docker.com/). This 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/)
+## Install Docker
+
+### Windows
+
+1. Use Docker Desktop via [docker.com Download](https://www.docker.com/products/docker-desktop/).
+
+2. You have to enable git symlinks before cloning the repository.
+ This repository uses symbolic links that are not enabled by default on Windows git. To enable them, [turn on Developer Mode](https://windowsreport.com/windows-11-developer-mode/) on Windows and run `git config --global core.symlinks true` to enable symlinks in Git. See [this StackOverflow question](https://stackoverflow.com/questions/5917249/git-symbolic-links-in-windows) for more information.
+
+### Mac
+
+- Use Docker Desktop via [docker.com Download](https://www.docker.com/products/docker-desktop/).
+- Or [Homebrew](https://formulae.brew.sh/cask/docker).
+
+### Linux
+
+Use [Docker Engine](https://docs.docker.com/engine/install/ubuntu/) with the [docker-compose-plugin](https://docs.docker.com/compose/install/linux/)
+
+## Clone repository
The first step is to fork/clone the repo to your local machine:
- git clone https://github.com/openstreetmap/openstreetmap-website.git
+```
+git clone https://github.com/openstreetmap/openstreetmap-website.git
+```
Now change working directory to the `openstreetmap-website`:
- cd openstreetmap-website
+```
+cd openstreetmap-website
+```
## Initial Setup
### Storage
- cp config/example.storage.yml config/storage.yml
+```
+cp config/example.storage.yml config/storage.yml
+```
### Database
- cp config/docker.database.yml config/database.yml
+```
+cp config/docker.database.yml config/database.yml
+```
## Prepare local settings file
This is a workaround. [See issues/2185 for details](https://github.com/openstreetmap/openstreetmap-website/issues/2185#issuecomment-508676026).
- touch config/settings.local.yml
+```
+touch config/settings.local.yml
+```
+
+**Windows users:** `touch` is not an availible command in Windows so just create a `settings.local.yml` file in the `config` directory, or if you have WSL you can run `wsl touch config/settings.local.yml`.
## Installation
To build local Docker images run from the root directory of the repository:
- docker-compose build
+```
+docker compose build
+```
If this is your first time running or you have removed cache this will take some time to complete. Once the Docker images have finished building you can launch the images as containers.
To launch the app run:
- docker-compose up -d
+```
+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
Run the Rails database migrations:
- docker-compose run --rm web bundle exec rake db:migrate
+```
+docker compose run --rm web bundle exec rails db:migrate
+```
### Tests
-Run the test suite by running:
+Prepare the test database:
+
+```
+docker compose run --rm web bundle exec rails db:test:prepare
+```
+
+Run the test suite:
+
+```
+docker compose run --rm web bundle exec rails test:all
+```
+
+If you encounter errors about missing assets, precompile the assets:
- docker-compose run --rm web bundle exec rails test:all
+```
+docker compose run --rm web bundle exec rake assets:precompile
+```
### Loading an OSM extract
For example, let's download the District of Columbia from Geofabrik or [any other region](https://download.geofabrik.de):
- wget https://download.geofabrik.de/north-america/us/district-of-columbia-latest.osm.pbf
+```
+wget https://download.geofabrik.de/north-america/us/district-of-columbia-latest.osm.pbf
+```
You can now use Docker to load this extract into your local Docker-based OSM instance:
- docker-compose run --rm web osmosis \
- -verbose \
- --read-pbf district-of-columbia-latest.osm.pbf \
- --log-progress \
- --write-apidb \
- host="db" \
- database="openstreetmap" \
- user="openstreetmap" \
- validateSchemaVersion="no"
+```
+docker compose run --rm web osmosis \
+ -verbose \
+ --read-pbf district-of-columbia-latest.osm.pbf \
+ --log-progress \
+ --write-apidb \
+ host="db" \
+ database="openstreetmap" \
+ user="openstreetmap" \
+ validateSchemaVersion="no"
+```
+
+**Windows users:** Powershell uses `` ` `` and CMD uses `^` at the end of each line, e.g.:
+
+```
+docker compose run --rm web osmosis `
+ -verbose `
+ --read-pbf district-of-columbia-latest.osm.pbf `
+ --log-progress `
+ --write-apidb `
+ host="db" `
+ database="openstreetmap" `
+ user="openstreetmap" `
+ validateSchemaVersion="no"
+```
Once you have data loaded for Washington, DC you should be able to navigate to [`http://localhost:3000/#map=12/38.8938/-77.0146`](http://localhost:3000/#map=12/38.8938/-77.0146) to begin working with your local instance.
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
+```
+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
+```
+docker compose exec web bash
+```
Similarly, if you want to `exec` in the db container use:
- docker-compose exec db bash
+```
+docker compose exec db bash
+```
