T had a good idea, since we have a working image on the server, I should be able to push it directly up to docker hub w/o having to build it.
looks like the feature server image actually belongs to E, while the local was pointing to T's account. No idea if there is a meaningful difference there. I'm going to try and push up E's image and see if it works locally.

docker image tag 77f91898ad50 marlinnetwork/jms-pimcore-5-feature:latestdocker push marlinnetwork/jms-pimcore-5-feature:latest
did not work locally, same issue "unused bindings", maybe it's not the image after all, maybe it's that ssl removal from earlier in the process.
restored composer.lock from the server, everything installs ok, but that image from the server needs a proxy I think
testing making a new feature environment with the copied image
