Hej everyone. My traefik setup has been up and running for a few months now. I love it, a bit scary to switch at first, but I encourage you to look at, if you haven’t. Middelwares are amazing: I mostly use it for CrowdSec and authentication. Theres two things I could use some feedback, though.
I mostly use docker labels to setup routers in traefik. Some people only define on router (HTTP) and some both (+ HTTPS) and I did the latter.
So, I don’t want to serve HTTP at all, all will be redirected to HTTPS anyway. What I don’t know is, if I can skip the HTTP part. Must I define the web entrypoint in order for redirect to work? Or can I define it in the traefik.yml as I did below?
I use homepage (from benphelps) as my dashboard and noticed, that when I refresh the page, all those widgets take a long time to load. They did not do that, when I connecte homepage to those services directly using IP:PORT. Now I use URLs provided by traefik, and it’s slow. It’s not really a problem, but I wonder, if I made a mistake somewhere. I’m still a beginner when it comes to this, so any pointers in the right direction are apprecciated. Thank you =)
Serving 80 on the LAN should be OK as long as you have reasonable control over all the Ethernet wires and WiFi access points.
would using the HSTS header still prevent someone from explicity requesting your domain via http:// entirely in your examples 3 and 4?
You can’t control what clients do, you can only control what your server does.
In case 4 the hijacking took place before they even got to your server so it doesn’t matter anymore.
In case 3, if they manage to make it to your server and you have a redirect from 80 to 443 and HSTS on 443 they will narrowly escape future hijacks. So a redirect is not technically a bad thing to have, provided you also have HSTS.
You can’t control what clients do, you can only control what your server does.
Exactly, I should have said what would the server do when clients try to connect via http:// with and without the HSTS header but I see what you mean now. Thanks for the explanation!
One more thing, to make sure everything is clear: the HSTS header only matters over TLS. Servers are not supposed to give it over plain connections (could be faked) and browsers must ignore it if it’s not TLS.
