For GitHub, ME_CONFIG_MONGODB_URL is present but missing on Docker Hub
For Docker Hub, ME_CONFIG_MONGODB_ADMINUSERNAME, ME_CONFIG_MONGODB_ADMINPASSWORD, ME_CONFIG_MONGODB_PORT, and ME_CONFIG_MONGODB_SERVER is present but missing on GitHub

If pulling images from Docker Hub as per GitHub docs

$ docker run --link some_mongo_container:mongo -p 8081:8081 -e ME_CONFIG_MONGODB_URL="mongodb://mongo:27017" mongo-express

Which configuration settings are relevant?

The ones on GitHub as you use the latest tag (implicit).

if you use ME_CONFIG_MONGODB_SERVER it still works if you use the default "mongo" as the name of your service. It would not work when I renamed mine to "mongodb". However, ME_CONFIG_MONGODB_URL worked just fine and I switched my compose file to use that.
