Step 3: Linking Containers ... Not clear you are meant to stop the old users-service

[That-David-Guy]

Hey

This is for your blog entry: http://www.dwmkerr.com/learn-docker-by-building-a-microservice/

In step 3: Linking Container with the 'link' parameter, I had both containers running when I tried to run the following docker run -it -p 8123:8123 --link db:db -e DATABASE_HOST=DB users-service.

My understanding was it would connect two currently running containers, not a one currently running to a new one. The error message wasn't helpful at all either.

It would had been clearer to me if you specifically state you have to stop the users-service container before running this command.

Cheers
