The default "traefik" endpoint is the only endpoint that does not return 404 for every request

Traefik Traefik v2
#1

Hi.

Can somebody please tell me what I am doing wrong?

I am trying to do four things:

  • all HTTP ingress must be redirected to HTTPS
  • all HTTPS ingress for the path / should b forwarded to http://localhost:9000/cerebro/
  • all HTTPS ingress for the path /dashboard should be sent to the internal dashboard service
  • all HTTPS ingress for the path /api should be sent to the internal api service

to simplify things, i am running traefik as root:

root@com:/home/karl# /opt/traefik/traefik --configfile=/etc/traefik/traefik.toml

Here's my static config:

root@com:/etc/traefik# cat traefik.toml

Can somebody tell me what i am missing?

I have made a tiny . bit of progress: i can now get the / path to forward traffic to the cerebro backend!

I needed to add the flag indicating that TLS would be resolved:

  [http.routers.cerebro]
    # Any request that comes in on the HTTPS entrypoint
    # NOTE: since the traefik entry point seems to work, see if i can wire up the router to it as well...
    entryPoints = ["websecure"]

    # And is for the / path
    rule = "PathPrefix(`/cerebro`)"

    # Should get re-written so the the /cerebro/ path is added to the query
    #middlewares = ["add-cerebro-prefix"]

    # And then forwarded to the cerebro service
    service = "cerebro"

    # will terminate the TLS request
    [http.routers.cerebro.tls]

But i am still unable to get the HTTP -> HTTPS redirect working and the dashboard can't be accessed...

After a bit of head scratching, i've managed to get everything working. Posting my solution here for the benefit of anybody else that wants to use traefik but wishes there were any useful/working examples out there.

First:
The docs don't make is super explicit: you MUST have a "dynamic" provider. This provider can also be just a flat file or directory of files on the host. Why you can't just have your static configuration in the main traefik.toml file is beyond me. Kinda silly to use dynamic configuration... for a static config. But i digress.

Here's my traefik.toml:

################################################################
#
# Configuration for Traefik v2.
#
# All HTTP traffic MUST be immediately redirected to https
#
# The only backend service that needs to be exposed is Cerebro
#   via the /cerebro path
#
# The dashboard/API should be exposed via the /dashboard path
#
# The ping endpoint must be port 8080; http is OK
################################################################

################################################################
# Global configuration
################################################################
[global]
  checkNewVersion = true
  # Nothing wrong w/ letting them know it's in use
  # See: https://docs.traefik.io/contributing/data-collection/
  sendAnonymousUsage = true

################################################################
# Entrypoints configuration
################################################################

[entryPoints]
  # We want all http to be immediately upgraded to https
  [entryPoints.web]
    address = ":80"
  
  # All traffic will be over TLS
  [entryPoints.websecure]
    address = ":443"

  # And this is the endpoint that we'll monitor traefik health with
  [entryPoints.ping]
    address = ":8080"

################################################################
# Traefik logs configuration
################################################################

# Traefik logs
# Enabled by default and log to stdout
#
# Optional
#
[log]
  level = "INFO"

################################################################
# API and dashboard configuration
# See: https://docs.traefik.io/v2.1/operations/api/
################################################################

# Enable API and dashboard
[api]
  # Don't just have the api, also have a GUI
  dashboard = true

  # When enabled, the service is wired up do an entrypoint called "traefik" which appears to have no auth middleware
  # and is on port 8081
  ##
  insecure = false

################################################################
# Ping configuration
# See: https://docs.traefik.io/v2.1/operations/ping/
################################################################

# Enable ping endpoint; this is what consul-agent will check against!
[ping]
  entryPoint = "ping"

################################################################
# Provider configuration
# See: https://docs.traefik.io/providers/file/
################################################################

[providers.file]
  # ALL toml files here are loaded
  directory = "/etc/traefik/dynamic/"

Here's my dynamic/cerebro.toml:

##
# Handles all traffic to the /cerebro/* endpoint
#
##

[http.routers]
  [http.routers.cerebro]
    # Cerebro only accepts connections on HTTPS endpoint
    entryPoints = ["websecure"]

    # And is for the /cerebro path
    # See: https://docs.traefik.io/routing/routers/
    rule = "PathPrefix(`/cerebro`)"
    # For reasons that really suck, there's no easy way to automatically add the trailing /
    # So for now, we just suck it up and take the bad user experience (like configuring traefik isn't bad enough...) and tell users to bookmark the link w/ the slash already added

    # And then forwarded to the cerebro service
    service = "cerebro"

    # will terminate the TLS request
    # Note: This is REQUIRED, otherwise 404.
    [http.routers.cerebro.tls]

[http.services]
  [http.services.cerebro.loadBalancer]
    [[http.services.cerebro.loadBalancer.servers]]
      # Cerebro will expect traffic on port 9000
      url = "http://127.0.0.1:9000/"

Once i figured that out, the dashboard is nearly identical. My dynamic/dashboard.toml:


[http.routers]
  [http.routers.dashboard]
    # We want the dashboard to onlywork over HTTPS
    entryPoints = ["websecure"]

    # And is accessible on the /dashboard path
    # Dashboard is just a front end for API so we OR in the rule...
    # See: https://docs.traefik.io/routing/routers/
    rule = "PathPrefix(`/dashboard`) || PathPrefix(`/api`)"


    # And then forwarded to the internal dashboard/api service
    # See: https://docs.traefik.io/v2.1/operations/dashboard/#secure-mode
    service = "api@internal"

    # will terminate the TLS request
    # Note: This is REQUIRED, otherwise 404!
    [http.routers.dashboard.tls]

And the http redirect using the common noop technique... which seems like a hack to get it working... but, that's par for the course on traefik. Anyways, dynamic/redir.toml

##
# Traefik has some non-intuitive configuration. After much struggle, this is the approach seems to reliably
#   get http redirected to https.
#
# See: https://community.containo.us/t/global-http-to-https-redirect-in-v2/1658/3
##

[http.routers]
  [http.routers.redirecttohttps]
    entryPoints = ["web"]
    middlewares = ["httpsredirect"]
    # Literally ANY host
    rule = "HostRegexp(`{host:.+}`)"
    # Yep, no way to plug middleware directly into entrypoints... which is ironic as routers 
    # really don't do much more than what a rewrite() middleware would do if it had a special lookup_table
    # to consult...
    service = "noop"

[http.services]
  # noop service, the URL will be never called
  [http.services.noop.loadBalancer]
    [[http.services.noop.loadBalancer.servers]]
      url = "http://8.8.8.8"

[http.middlewares]
  [http.middlewares.httpsredirect.redirectScheme]
    scheme = "https"

Hope that helps somebody. If it doesn't, there's always a wealth of good examples about how to get nginx up and running and you'll probably sink less time into that compared trying to get traefik up.

Good job!
