Change the name of the port in your service to HTTP, or explicitly set the scheme as HTTP. From the Traefik docs:

There are 3 ways to configure the backend protocol for communication between Traefik and your pods:

Setting the scheme explicitly (http/https/h2c)

Configuring the name of the kubernetes service port to start with https (https)

Setting the kubernetes service port to use port 443 (https)

If you do not configure the above, Traefik will assume an http connection.

I’m running probably 100 services in Kubernetes in my homelab, most of it is made up of manifests that I’ve written translated over from docker compose files where I used to run the services. I also run some helm charts, but mostly just for more complex sets of services. I commit everything to a private GitHub repository, Flux replicates it to the cluster, and Renovate handles updates. Obviously writing manifests for Kubernetes is way more complex compared to Docker, but that’s kinda the point right, Kubernetes is way more powerful than Docker, so it’s going to come with extra complexity to match
