I have updated the docker image but forgot to commit the Dockerfile and is actually here 😓
Since you have done it already @jscgh I will build the image again with your Dockerfile and test it and if everything is fine I will then merge your PR and update the image on quay.io

I see there seem to be some files leak on this PR that overwrite some changes introduced by the last template update, it would be great if you could revert them again @jscgh
