How to: find a package containing an app (rpm-based)
dnf provides /path/to/file/or/pattern
dnf provides */sshd
```

1. Create a Dockerfile based on the following:
   - Base image should be debian-based or rpm-based
   - Should include packages containing `ps` application and network utilities like `ip`, `ss` and `arp`
   - Should run the `nmap` process as the `ENTRYPOINT` with arguments `-sn 172.17.0.0/16`
2. Build the Dockerfile with repository `local` and version `1.0`
3. List images
4. Run separate containers from the image as follows and review behaviour
   - do not specify any modes
   - in interactive mode with a shell
   - in detached mode, then check the logs
5. Edit the Dockerfile to run the same process and arguments but **not** as `ENTRYPOINT`
6. Repeat all three options in [4] and compare the behaviour
7. Clean up
