Covered in this SO post.
As of December 31st 2019:
-
Inspect Worker section of build log for line of form:
instance: travis-job-e823b3ef-f193-4b66-a4b2-bf847bc386ee travis-ci-sardonyx-xenial-1553530528-f909ac5 (via amqp)
-
Inspect line equivalent to https://github.com/travis-ci/packer-templates/blob/master/ci-sardonyx.yml#L5 to work out how this line relates to the Travis-CI Dockerhub tag, repo-name. Here I'm looking at the
ci-sardonyx
templates. You need thedocker_tag
andimage_name
lines in the file. -
In the case above, this becomes
travisci/ci-sardonyx:packer-1558623664-f909ac5
