TCP services are not HTTP, so netcat is the right tool to test it or openssl with piping message to session, see the examples above how I tested Whoami application. Register the IngressRouteTCP kind in the Kubernetes cluster before creating IngressRouteTCP objects. Not only can you configure Traefik Proxy to enforce TLS between the client and itself, but you can configure in many ways how TLS is operated between Traefik Proxy and the proxied services.

Most of the solutions I have seen, and they make sense, are to disable https on the container, but I can't do that because I'm trying to replicate as close to production as posible. Because my server has only one IP address, the host system is running traefik and using TLS passthrough to pass the HTTPS traffic to the VMs depending on the SNI hostname.

This process is entirely transparent to the user and appears as if the target service is responding . Thank you! Traefik & Kubernetes. If I had omitted the .tls.domains section, Traefik Proxy would have used the host ( in this example, something.my.domain) defined in the Host rule to generate a certificate. The browser will still display a warning because we're using a self-signed certificate. As a consequence, with respect to TLS stores, the only change that makes sense (and only if needed) is to configure the default TLSStore.
