Adding docker labels traefik.<servicename>.* properties like
- traefik.mycustomservice.port=443 - traefik.mycustomservice.frontend.rule=Path:/mycustomservice - traefik.anothercustomservice.port=8080 - traefik.anothercustomservice.frontend.rule=Path:/anotherservice all traffic to frontend /mycustomservice is redirected to the port 443 of the container while using /anotherservice will redirect to the port 8080 of the docker container More documentation in the docs/toml.md file Change-Id: Ifaa3bb00ef0a0f38aa189e0ca1586fde8c5ed862 Signed-off-by: Florent BENOIT <fbenoit@codenvy.com>

@ -823,6 +823,17 @@ Labels can be used on containers to override default behaviour:
|
|||
- `traefik.frontend.entryPoints=http,https`: assign this frontend to entry points `http` and `https`. Overrides `defaultEntryPoints`.
|
||||
- `traefik.docker.network`: Set the docker network to use for connections to this container
|
||||
|
||||
If several ports need to be exposed from a container, the services labels can be used
|
||||
- `traefik.<service-name>.port=443`: create a service binding with frontend/backend using this port. Overrides `traefik.port`.
|
||||
- `traefik.<service-name>.protocol=https`: assign `https` protocol. Overrides `traefik.protocol`.
|
||||
- `traefik.<service-name>.weight=10`: assign this service weight. Overrides `traefik.weight`.
|
||||
- `traefik.<service-name>.frontend.backend=fooBackend`: assign this service frontend to `foobackend`. Default is to assign to the service backend.
|
||||
- `traefik.<service-name>.frontend.entryPoints=http`: assign this service entrypoints. Overrides `traefik.frontend.entrypoints`.
|
||||
- `traefik.<service-name>.frontend.passHostHeader=true`: Forward client `Host` header to the backend. Overrides `traefik.frontend.passHostHeader`.
|
||||
- `traefik.<service-name>.frontend.priority=10`: assign the service frontend priority. Overrides `traefik.frontend.priority`.
|
||||
- `traefik.<service-name>.frontend.rule=Path:/foo`: assign the service frontend rule. Overrides `traefik.frontend.rule`.
|
||||
|
||||
|
||||
NB: when running inside a container, Træfɪk will need network access through `docker network connect <network> <traefik-container>`
