traefik-forward-auth VS vouch-proxy

BTW also keycloak and other similar products offer the oauth-proxy capability, I even used the original oauth2-proxy https://github.com/oauth2-proxy/oauth2-proxy for a while, but it was getting too difficult to maintain for me. I used for a while https://github.com/thomseddon/traefik-forward-auth that was a smart hack configuring a single upstream provider, but it look abandoned. So I was considering authentik but apparently it's just oauth2-proxy embedded in it, at that point why not use oauth2-proxy directly.

It seems there are some more recently updated forks.

Traefik Forward Auth

One way I got this to work (for another app that doesn’t go through cloudflare) was to use Traefik with forward-auth and this: https://github.com/thomseddon/traefik-forward-auth

In front of all of my private dashboards, I use Traefik Forward Auth to limit who can access them.

Hm, interesting. I have worked with traefik-forward-auth before, but I didn't know there is a fork. Are you using the fork? Would you happen to know if this issue from the original project still exists or if it's fixed in the fork?

https://github.com/thomseddon/traefik-forward-auth (just another option if everyone accessing already has a google account)

Traefik ingress + forward auth middleware + traefik-forward-auth does the trick.

Hey have u setup a forward auth? https://github.com/thomseddon/traefik-forward-auth

Look into vouch proxy

Vouch proxy is designed for this usage: https://github.com/vouch/vouch-proxy I don't think there are any nice UIs to configure it though so you'll need to be familiar with running it yourself.

Not sure this is a "best practice", but it lets me keep control of the Ingress resources inside their YAML configs. I've also layered Vouch Proxy into the ingress configurations to require SSO/MFA auth to access the resources behind the Ingress. Cloudflare has the ability to do this, but I found it cumbersome to keep track of the configs outside the K8s cluster.

I've used vouch proxy for my own stuff previously, before more recently moving to Cloudflare Access. vouch can be slightly janky at times to get working right, but once set up, it's been solid.

For example: nginx -> Vouch proxy -> KeyCloak -> Jellyfin

While this works, we were hoping to make access a bit easier with say an OpenID Connect SSO and reverse-proxy solution. I've seen Vouch Proxy, https://github.com/vouch/vouch-proxy which is really just SSO on top of nginx, but I'm wondering if there's a simpler way to do this.

You seem to be quite knowledgeable and a minimal provider with just the bare minimum would suffice for you. Have a look at Vouch Proxy, it does one thing and it does it well.
