Can't find other services with authn-server in github actions

[taoberquer]

Hi, I'm trying to access a database from a container with nslookup (nslookup is used when i am play migrate command) and I'm getting an error. I've made an example of my github actions to reproduce the error. If I've forgotten anything, please let me know.

The error :

Run nslookup postgres

Server:     127.0.0.11
Address:    127.0.0.11:53

** server can't find postgres.psu1waqqpzqu3mj[4](https://github.com/sedeotech/inferni/actions/runs/6588514445/job/17900939871#step:3:4)5gsqnyggvb.xx.internal.cloudapp.net: NXDOMAIN

    services:
      postgres:

    steps:
        - run: nslookup postgres

@taoberquer This is not the right place to get support for networking configurations in GitHub Actions or Docker. Please reply again with more detail if you have reason to believe the problem is related to AuthN.
