@vordimous, Thanks for the PR. This would be a useful addition in terms of maintaining the docker composer. However there are a couple of things we need to sort out before getting this merged. The things that we need to sort out are tracked through the issue [1]. Once those are sorted out we will merge the PR after re-evaluating. Furthermore, we will be closing this PR as there are alerts being generated for unmerged PRs that stand for a long time, with the aim of reopening it once the aforementioned concerns are sorted out.
