Thanks Ben. It does seem sensible to use build strategies but prior to a wholesale migration to OpenShift, and for existing workflows that may contain docker and docker-compose commands is there any reasonable option other than a an external (cloud/proprietary/dedicated) docker-enabled slave? I can, for example, just have a Docker slave available (outside the OpenShift cluster) but that’s not ideal.
Is there an _unsafe_ route I might be able to use now? I understand the issues around sharing a docker.sock but it seems to be an acceptable strategy for many. And, for a controlled environment, just mounting docker.sock is a rather neat (quick-n-dirty) solution. It may be that, was you say there’s no sensible route down the OpenShift/CICD road other than build strategies. It’s just that for existing/legacy projects not having docker.sock is quite a hill to climb. Thanks for your advice though, that has been gratefully received.
