I set up SSL certificates for my internal services behind Traefik, but I was having some issues obtaining the certificates. I ended up having to add this line in my Docker compose file to bypass PiHole which is controlling the internal hostnames for my domain:
- --certificatesresolvers.letsencrypt.acme.dnschallenge.resolvers=1.1.1.1:53,1.0.0.1:53
After adding that, I was able to successfully pull a cert. The issue is, I have a firewall set up that blocks DNS requests from everywhere except my DNS servers (PiHole), so I had to pause that rule temporarily to get the request to go through.
Wondering what I can do here (if anything) to resolve this without having to disable my firewall rules regularly.
I have just recently started messing with Authentik. And I can confirm OIDC claims and whatnot are an absolute nightmare. I have some experience setting up SAML stuff from my work, but I only do that if our main guy is out and I always struggle with it there too.
Your setup sounds the most like what I am doing now, minus the DMZ. But all of my containers are rootless. I am running everything on TrueNAS right now.
I think I will lean more on Authentik, as the provisioning of users and giving them access to services through that is very easy. I will probably stick with Cloudflare for the time being, but I will look more into Pangolin.
