Testsuite: Docker controller leaves stray volumes and fills up disk space unnecessairly over time ------------------------------------------------------------------------------------------------- Key: JBTM-3019 URL: https://issues.jboss.org/browse/JBTM-3019 Project: JBoss Transaction Manager Issue Type: Bug Components: Testing Affects Versions: 5.8.1.Final Environment: Docker enabled Jenkins slaves Reporter: Michal Karm Babacek Assignee: Michal Karm Babacek Priority: Minor Fix For: 5.next h3. Problem The Docker controller that allocates databases as Docker containers cleans up containers and does not leave unnecessary images: {code} [root@karm-centos7-x86-64 ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/postgres 9.4 26bd9b04b948 6 days ago 232 MB docker.io/postgres 10 0965cdc98045 6 days ago 234 MB docker.io/postgres <none> ed5db6e669ff 7 weeks ago 263 MB docker.io/postgres <none> 30121e967865 7 weeks ago 289 MB [root@karm-centos7-x86-64 ~]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES [root@karm-centos7-x86-64 ~]# {code} Although it leaves stray container volumes for some reason: {code} [root@karm-centos7-x86-64 ~]# du -hs /var/lib/docker-latest/volumes 15G /var/lib/docker-latest/volumes [root@karm-centos7-x86-64 ~]# docker volume ls -qf dangling=true | wc -l 409 {code} It unnecessarily clogs the slaves' disk space. The 15G of garbage has been created over dozens and dozens of builds with at least two containers each, but it shouldn't be happening anyway. h3. Call to action Review whether [removeContainerCmd|https://github.com/jbosstm/narayana/blob/master/tools/...] is supposed to be enough to not only remove the container but to also remove its volume. h3. Workaround {code} docker volume prune {code}
