Docker-compose instructions don't work


I’m trying to spin up a local instance of Rocket Chat, to work on a new project. The instructions for getting up and running with docker-compose don’t work for me.

Here’s what’s happened so far:

curl -L -o docker-compose.yml

docker-compose up

No matter how much I fiddle with the config, I can’t get the Rocket Chat server to connect to mongo. It always results in MongoServerSelectionError: connect ECONNREFUSED
