# You shouldn't need `docker inspect couchbase_db_1 | jq -r .[0].NetworkSettings.Networks.couchbase_backend.IPAddress`
# You should just be able to refer to the containers by name. e.g. couchbase_db_1:8091
# However if you do, you get the error
# ERROR: unable to server-add couchbase_db_2:8091 (400) Bad Request

# Normally I'd never open port 8091 on a public IP address like that but it's convenient for this example.
# If you don't open it and only have under expose, you would need to run a temporary proxy like https://community.getcarina.com/t/connecting-to-db-via-terminal/143/7?u=etoews
# to be able to access it.
