About docker.

When you create user inside docker container it is good to determine UID and GID
Like

RUN groupadd -r -g 5055 raccoon && useradd -r -u 5055 -g raccoon raccoon
USER raccoon
ENTRYPOINT ["raccoon"]

and then you can run it like

mkdir -p /srv/raccoon/
chown -R 5055:5055 /srv/raccoon/
docker run --rm --name raccoon -v /srv/raccoon:/home/raccoon evyatarmeged/raccoon:latest  example.com -o /home/raccoon

Also you can connect autobuild on docker hub.
