Process control for your OpenProject installation

Packaged installation

Restart all the OpenProject processes

sudo openproject restart

Run commands like rake tasks or rails console

The OpenProject command line tool supports running rake tasks and known scripts. For instance:

Get the current version of OpenProject

sudo openproject run bundle exec rake version

Launch an interactive console to directly interact with the underlying Ruby on Rails application:

sudo openproject run console

Manually launch the database migrations:

sudo openproject run rake db:migrate

Check the version of Ruby used by OpenProject:

sudo openproject run ruby -v

Scaling the number of web workers

Note: Depending on your free RAM on your system, we recommend you raise the default number of web processes. The default from 9.0.3 onwards is 4 web processes. Each worker will take roughly 300-400MB RAM.

We recommend at least 4 web processes. Please check your current web processes count with:

sudo openproject config:get OPENPROJECT_WEB_WORKERS

If it returns nothing, the default process count of 4 applies. To increase or decrease the process count, call

sudo openproject config:set OPENPROJECT_WEB_WORKERS=number

Where number is a positive number between 1 and round(AVAILABLE_RAM * 1.5).

After changing these values, simply restart the web process:

sudo openproject restart web

All-in-one Docker-based installation

Run commands like rake tasks or rails console

You can spawn an interactive shell in your docker container to run commands in the OpenProject environment.

First, find out the container ID of your web process with:

# Ensure the containers are running with the following output
docker ps | gre web_1

# save the container ID as a env variable $CID
export CID=$(docker ps | grep web_1 | cut -d' ' -f 1)

We can now run commands against that container

Run a bash shell in the container

docker exec -it $CIT bash

Get the current version of OpenProject

docker exec -it $CIT bash -c "RAILS_ENV=production rails version"

In case of using kubernetes, the command is a bit different

kubectl exec -it {POD_ID} -- bash -c "RAILS_ENV=production bundle exec rails console"

Launch an interactive console to directly interact with the underlying Ruby on Rails application:

docker exec -it $CIT bash -c "RAILS_ENV=production rails console"

docker-compose based installation

Spawn a rails console

You can spawn an interactive shell in your docker-compose setup container to run commands in the OpenProject environment.

The following command will spawn a Rails console in the container:

docker-compose run web bash -c "RAILS_ENV=production bundle exec rails console"
