Jenkins node integration-slave-docker-1041 was taken offline by @Krinkle over the weekend. Job failure due to lack of disk space was cited in the message.

It seems non-Quibble Docker based jobs are still leaving a full src directory after the run which shouldn't be necessary or desirable as it leads to an eventual exhaustion of the workspace directory. All remaining Docker jobs should have a post-build step added that removes the src directory following each build—and perhaps other directories as well that are not expected to store artifacts (e.g. tmp).

This round of disk-space related failures is related but not due to the same root cause as T202457: mediawiki-quibble docker jobs fails due to disk full. However, it may actually occur more frequently due to the splitting of the LVM volume group for both the /srv and /var/lib/docker logical volumes, and also due to the consolidation of executors on larger shared instances (see T202160)—more executors on a single instance means more potential for multiple dirty directories per job (i.e. {job-name}@{executor} directories).

In any case, it would seem desirable to have builds clean up all directories that aren't used to store artifacts at the end of the build process, not the beginning.
