Working around Docker DNS issues on Fedora 33. Adapted from https://stackoverflow.com/a/60113249

Problem

Docker on Fedora 33 has issues with systemd-resolved. This causes DNS issues when, for example, connecting VPNs, because it'll use the wrong DNS server, especially if you have several configured. The one from systemd-resolved is ignored since it's a 127.0.0.X address.

This causes containers to not be able to resolve addresses on the private network (VPN).

Solution

Use dnsmasq to listen on docker0 and forward DNS requests to systemd-resolved running on 127.0.0.53.

Working with minishift

Docs

If on Fedora, RHEL one should use centos iso to make pushing to registry work
$ minishift start --iso-url centos

(can this be configured in a minishift profile to be used?)

Use docker deamon from minishift
