How Routing traffic depending on path not domain in docker

[mwaaas]

I have tried this and its not working

traefik:
  image: traefik
  command: --web --docker --docker.domain=docker.localhost --logLevel=DEBUG
  ports:
    - "80:80"
    - "8080:8080"
    - "443:443"
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
    - /dev/null:/traefik.toml

machine:
  image: katacoda/docker-http-server
  labels:
    - "traefik.backend=machine-echo"
    - "traefik.frontend.rule=Path:machine-echo./machine"

echo:
  image: katacoda/docker-http-server:v2
  labels:
    - "traefik.backend=echo"
    - "traefik.frontend.rule=Path:echo-echo./echo"

very curious about this also, to route traffic to different api version ...

[emilevauge]

What is not working exactly? Have you tried PathPrefix or PathPrefixStrip rules instead?

[mwaaas]

@emilevauge I have tried using this - "traefik.frontend.rule=Path:echo-echo./echo" I can't see the documentation of "PathPrefix" or "PathPrefixStrip"

[mwaaas]

@emilevauge thanks

Finally got it, it wasn't so obvious from the documentation

traefik: 
  command: "--web --docker --docker.domain=docker.localhost --logLevel=DEBUG"
  image: traefik
  ports: 
    - "80:80"
    - "8080:8080"
  volumes: 
    - "/var/run/docker.sock:/var/run/docker.sock"
    - "/dev/null:/traefik.toml"
whoami1: 
  image: emilevauge/whoami
  labels: 
    - traefik.backend=whoami
    - "traefik.frontend.rule=Host:whoami.docker.localhost"
whoami2: 
  image: emilevauge/whoami
  labels: 
    - traefik.backend=whoami2
    - "traefik.frontend.rule=Path:/test2/, _/mwas/_"

@emilevauge quick question how does one do regex for path in traefik

for example for certain domain I want to forward trafic with this path foo to containerB and the container with path boo to containerC and empty path to containerD

Hi Guys,

I am trying to do the same but cannot make it work.
I am trying to have mydomain.dev/pma pointing on the phpmyadmin backend:

web:
    image: nginx
    links:
        - app
    volumes_from:
        - app
    volumes:
        - ./web/nginx.conf:/etc/nginx/nginx.conf
    labels:
        - "traefik.backend=web"
        - "traefik.frontend.rule=Host:mydomain.dev"
        - "traefik.port=80"

phpmyadmin:
    image: phpmyadmin/phpmyadmin
    links:
        - db
    labels:
        - "traefik.backend=phpmyadmin"
        - "traefik.frontend.rule=Host:mydomain.dev;Path:/pma"

Anyone having an idea how to solve this?

Thanks

[mwaaas]

@romainlaisne I use this label
"traefik.frontend.rule=PathPrefix:/static/"

Hi,

I haven't solved my issue yet, but I think that it is not Traefik causing me trouble in the end.
I use Symfony and the routing system is coming on top of everything which I think causes troubles.

Thanks for you help @mwaaas.

@romainlaisne Did you find a solution for you mydomain.dev/pma problem? I've got the same problem.

[wvdongen]

@romainlaisne Found the answer, use "traefik.frontend.rule=Host:mydomain.dev;PathPrefixStrip:/pma"

[benpetsch]

Solution for me:

I tried something similar to:

    [...]
    labels:
        - "traefik.frontend.rule=PathPrefixStrip:/pma"
        - "traefik.frontend.rule=Host:mydomain.dev"
        [...]

But figured out, this does not work. (Maybe line 1 does overwrite line 2?)

For me worked:

    [...]
    labels:
        - traefik.frontend.rule=Host:mydomain.dev;PathPrefixStrip:/pma
        [...]

I was looking for path based routing as well and I finally made it working like following referring to all above conversation and official document.

docker run -dit --name xxx \
    --label "traefik.frontend.rule=PathPrefixStrip:/xxx/" \
    --label traefik.backend=xxx \
    myapp

The only caveat is it works with http://mydomain.com/xxx/ but doesn't work without last slash like http://mydomain.com/xxx
I tried to make the rule as PathPrefixStrip:/xxx but no luck.
Thanks!
