I can't connect a local database to docker-compose running a Superset container.

I'm using Superset to show information of a database that is stored locally. While Superset is running as a container ran by docker-compose. Superset can't access the database duo to the container network not being able to access the same IP address and port of localhost.

For this your Apache Superset should also running on your local system.

  • This statement is incorrect. Apache Superset mentions this setup in their [own documentation](https://superset.apache.org/docs/installation/installing-superset-using-docker-compose#5-connecting-superset-to-your-local-database-instance). – Sebastian Liebscher Jul 25 '23 at 12:44

You can connect to your local database by using the docker daemon's network bridge docker0.

  • check ip addr show docker0 and look for inet
  • switch from localhost to docker0's address (example 172.17.0.1)
~ ip addr show docker0
9: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default 
    link/ether 1a:2b:3c:4d:5e:6f brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
       valid_lft forever preferred_lft forever

Apache Superset's documentation also mentions this here. More information on your underlying question: From inside of a Docker container, how do I connect to the localhost of the machine?
