OpenProject development setup via docker

The quickest way to get started developing OpenProject is to use the docker setup.

Setup

1) Checkout the code

First you will need to checkout the code as usual.

git clone https://github.com/opf/openproject.git

This will checkout the dev branch in openproject. Change into that directory.

If you have OpenProject checked out already make sure that you do not have a config/database.yml as that will interfere with the database connection inside of the docker containers.

3) Configure environment

Copy the env example to .env

cp .env.example .env

Afterwards, set the environment variables to your liking. DEV_UID and DEV_GID are required to be set so your project directory will not end up with files owned by root.

2) Setup database and install dependencies

# Start the database. It needs to be running to run migrations and seeders
docker-compose up -d db

# Install frontend dependencies
docker-compose run frontend npm i

# Install backend dependencies, migrate, and seed
docker-compose run backend setup

3) Start the stack

The docker compose file also has the test containers defined. The easiest way to start only the development stack, use

docker-compose up frontend

To see the backend logs as well, use

docker-compose up frontend backend

This starts only the frontend and backend containers and their dependencies. This excludes the testing containers, which are harmless to start as well, but take up system resources and clog your logs while running.

This process can take quite a long time on the first run where all gems are installed for the first time. However, these are cached in a docker volume. Meaning that from the 2nd run onwards it will start a lot quicker.

Wait until you see frontend_1 | : Compiled successfully. and backend_1 | => Rails 6.0.2.2 application starting in development http://0.0.0.0:3000 in the logs. This means both frontend and backend have come up successfully. You can now access OpenProject under http://localhost:3000, and via the live-reloaded under http://localhost:4200.

Again the first request to the server can take some time too. But subsequent requests will be a lot faster.

Changes you make to the code will be picked up automatically. No need to restart the containers.

Docker

You can stop the processes via Ctrl + C. You can also run everything in the background by adding the -d option as in bin/compose up -d. In that case you'll still be able to see the logs using docker logs with the respective container name. You can see the started containers using docker ps.

Volumes

There are volumes for

the attachments (_opdata)
the database (_pgdata)
the bundle (rubygems) (_bundle)
the tmp directory (_tmp)
the test database (_pgdata-test)
the test tmp directory (_tmp-test)

This means these will stay between runs even if you stop and restart the containers. If you want to reset the data you can delete the docker volumes via docker volume rm.

Running tests

Start all linked containers and migrate the test database first:

docker-compose up backend-test

Afterwards, you can start the tests in the running backend-test container:

docker-compose run backend-test bundle exec rspec

Tests are ran within Selenium containers, on a small local Selenium grid. You can connect to the containers via VNC if you want to see what the browsers are doing. gvncviewer on Linux is a good tool for this. Check out the docker-compose file to see which port each browser container is exposed on. The password is secret for all.

Local files

Running the docker images will change some of your local files in the mounted code directory. The file frontend/npm-shrinkwrap.json may be modified. You can just reset these changes if you want to commit something or pull the latest changes.
