+Usualy I seperate git repo from Dockerfile, so I copy these docker files to same directory where repo is cloned. I serve it under traefik, so I added labels to composer.
+
+`instances.db` should be copied, too.
+
+`Makefile` is wrapper to add index hosts and reject hosts. Run `make help` for more info.
