docker build -t filodreamz/boinc .
Create an account for the BOINC project you want to help. All you need is the project URL and your key. In my case (rosetta@home), these can be found here https://boinc.bakerlab.org/rosetta/weak_auth.php.
docker run -ti -e "boincurl={project_url}" -e "boinckey={your_key}" filodreamz/boinc
...or set the env variables in docker-compose.yml and
docker-compose up -d
