Traefik2 Local Services

Traefik Traefik v2 (latest)
1

Hi,

I currently have a few back end services running and were working fine with V1.7 with the following rules

[backends]

[backends.backend1]
    [backends.backend1.servers]
      [backends.backend1.servers.server0]
        url = "http://localhost:8082"

[frontends]

[frontends.frontend1]
  entryPoints = ["http", "https"]
  backend = "backend1"
  passHostHeader = true

[frontends.frontend1.routes]
    [frontends.frontend1.routes.route0]
      rule = "Host:DOMAIN"

In this instance it was a host nginx service

Ive attempted to replicate this with the new HTTP routers in V2 and all i seem to be getting is 404s not found

[http]
    [http.routers]
       [http.routers.my-router]
          rule = "Host(`DOMAIN`)"
          service = "nginxhost"
          entrypoint=["http", "https"]

    [http.services]
          [http.services.nginxhost.loadbalancer]
            [[http.services.nginxhost.loadbalancer.servers]]
              url = "http://localhost:8082"

The services and routes are clearly showing in the dashboard - any help would be appreciated

I think the only problem I see is entrypoint should be entrypoints

Thanks ive change that and still 404 errors

Can you have a look at nginxhost on the services page ?

I did note that the servicee definition has double []

Thanks good spot, I removed the double brackets and still the same VSC must have added the [[ ]]

Hello,

the double brackets are required: it's the syntax of a list in TOML.

https://docs.traefik.io/v2.2/routing/services/

Your problem is related to the missing TLS section on your router.

https://docs.traefik.io/v2.2/routing/routers/#tls

[http]
    [http.routers]
       [http.routers.my-router]
          rule = "Host(`DOMAIN`)"
          service = "nginxhost"
          entryPoints=["https"]
          [http.routers.my-router.tls]

    [http.services]
          [http.services.nginxhost.loadBalancer]
            [[http.services.nginxhost.loadBalancer.servers]]
              url = "http://localhost:8082"

Also TOML is case sensitive so take care of the names :wink:

I recommend to update your Traefik to v2.2.1 like you will be able to use a simplest HTTP to HTTPS redirection:
