Systemd Resolved With Consul Agent

I pieced this technique together a while back and created a gist for it. I’m creating this post as a pointer to that gist so I have something that’s a bit easier to reference and refer others to.

And i want to test out the hugo shortcode for embedding a gist :smirk:.

The really short version:

Create a dedicated interface that can only be accessed from the local system
Bind the consul-agent’s DNS service to this local only interface
Tell systemd-resolved that all hostnames with the .consul TLD can be resolved via a DNS server on this local interface

No need to disable resolved and replace it with dnsmasq :smile:
