The docker service will not be directly reachable from the internet; it will have to go through the TLS link to Traefik, Communications between Traefik and the proxied docker service will all happen on the local docker network, No ports need to be opened up on the physical server for the docker service. The VM supports HTTP/3 and the UDP packets are passed through. This is known as TLS-passthrough. First of all, a very useful finding is that curl, when run with the --http3 option, does not read the Alt-Svc header, but makes a HTTP/3 UDP request straight against the port specified in the URL (443 by default). As you can see, I defined a certificate resolver named le of type acme. TLS handshakes will be slow when requesting a hostname certificate for the first time, which can lead to DDoS attacks.

Use the configuration file shown below to quickly generate the certificate (but be sure to change the CN and DNS.1 lines to reflect your public IP). What did you do? Traefik v2 is a modern HTTP reverse proxy and load balancer, which is used by HomelabOS to automatically make accessible all the docker containers, both on http and https (with Let's Encrypt certificate).. Exposing other services. Also see the full example with Let's Encrypt. I've found that the initial configuration needs a few enhancements that's why I've fixed that and make it happen that all services from the initial config should work now. envoy needs discovery through KV stores / APIs (sorry, I don't know it very well). Deploy traefik and a couple of services, some with http routers and others with tcp routers & tls passthrough using a different subdomain per service. For instance, in the example below, there is a first level of load-balancing because there is a (Weighted Round Robin) load-balancing of the two whoami services, I can imagine two different types of setup: Neither of these setups sound very pleasing, but I'm wondering whether any of them will work at all? I was hoping I just had to enable HTTP/3 on the host system, similar to how it was when I first enabled HTTP/2, but I quickly realized that the setup will be more complicated than that. Traefik currently only uses the TLS Store named "default". the reading capability is never closed). My current hypothesis is on how traefik handles connection reuse for http2 When web application security is a top concern then SSL passthrough should be opted at load balancer so that an incoming security sockets layer (SSL) request is not decrypted at the load balancer rather passed along to the server for decryption as is. Thanks for contributing an answer to Stack Overflow! CLI. Lets also be certain Traefik Proxy listens to this port thanks to an entrypoint Ill name web-secure.
