Up until now, the deployment user was in the
sudogroup and was therefore able to execute all commands.This somehow circumvented the usage of our
roles/artemis/templates/artemis_deployment_sudoers.j2template.With this change, we remove the deployment user from the
sudoandartemisgroup so that the deployment user has only minimal access rights.Additionally, the deployment user was able to execute arbitrary commands in the docker container using the deployment script and
execprovided by docker compose. Especially as we want the deployment user not to be able to read the configuration and secrets, we now limit the set of commands of theartemis-docker.shscript torestart.
