I just tried to install Traefik with Docker. The whole thing works so far. But I still get this error message:

> level=error msg="the router traefik-secure@docker uses a non-existent resolver: http"

My docker-compose.yml

One more question. Is it better to add these "rules" to docker-compose.yml or to traefik.toml?

Many thanks for any help

Hi @Koda

You have do define a certificate resolver in your static configuration. Did you do that? Is it 'named' http?

@cakiwi  
No. That was my mistake. Thanks a lot
