Allow multiple rules from docker labels containers with traefik.<servicename>.* properties #1257

benoitf · 2017-03-08T14:19:50Z

It matches expectation of #444
If labels contain for example:

traefik.mycustomservice.port=443
traefik.mycustomservice.frontend.rule=Path:/mycustomservice
traefik.anothercustomservice.port=8080
traefik.anothercustomservice.frontend.rule=Path:/anotherservice

all traffic to frontend on path /mycustomservice is redirected to the port 443 of the container defining the label while using path /anotherservice will redirect to the port 8080 of the docker container defining the label

Available properties are
traefik.<service-name>.port
traefik.<service-name>.weight
traefik.<service-name>.protocol
traefik.<service-name>.frontend.backend
traefik.<service-name>.frontend.entryPoints
traefik.<service-name>.frontend.rule
traefik.<service-name>.frontend.passHostHeader
traefik.<service-name>.frontend.priority
traefik.<service-name>.frontend.rule

More documentation in the docs/toml.md file
new tests added to docker_tests.go

Looks really good, just one small comment 👼

vdemeester · 2017-03-10T15:15:31Z

provider/docker.go

+
+// Extract entrypoints from labels for a given service and a given docker container
+func (provider *Docker) getServiceEntryPoints(container dockerData, serviceName string) []string {
+	if entryPoints, ok := extractServicesLabels(container.Labels)[serviceName]["frontend.entryPoints"]; ok {


Not a huge fan of that notation ; would have prefered to pass serviceName and the key (here frontend.entryPoints) as arguments (and thus make it sure these function don't care how the label are extracted, using maps or something else).

ok so you prefer something more generic ?
getServiceValue $container $serviceName $key ?

yeah, I don't want to surface the fact that this is a map or something else 👼

if entryPoints, ok := getContainerServiceLabel(container, serviceName, "frontend.entryPoints")

looks of for you ?

looks perfect to me 👼 👍

I've updated to call getContainerServiceLabel (this new function is delegating to extractServicesLabels)
Let me know if it's ok or if you want to remove as well the intermediate extractServicesLabels

I'll have to work on these, because our unit tests are way too verbose (but it's orthogonal to this PR, just thinking outloud 🤔 ).

ah for sure they are verbose ^^

benoitf · 2017-03-11T07:51:55Z

@intelradoux you can use Host in the front-end rule. So AFAIK this is possible with this PR
You define two services with two different Host front-end rule

LGTM 🐯

@benoitf Really good job 😍
LGTM
Could you squash your commits before we merge it ?

benoitf · 2017-03-13T18:52:32Z

thx. So it won't be in 1.2 ?

vdemeester · 2017-03-14T10:32:53Z

@benoitf yeah, putting this in 1.3 milestone. 1.2 is already freezed so… 👼 😅

benoitf · 2017-03-14T10:40:53Z

ok :)

dcrystalj · 2017-03-21T09:40:11Z

I am testing your PR now.

I created simple service as

    docker service create \
    --name=visualizer \
    --network=proxy \
    --constraint=node.role==manager \
    --mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \
    --label traefik.visualizer.port=8080 \
    --label traefik.visualizer.network=proxy \
    --label traefik.visualizer.frontend.rule=Host:visualizer.traefik \
    --label traefik.visualizer.frontend.entryPoints=http,https \
    manomarks/visualizer:latest

While putting old school traefik.port is working this .visualizer. as <service-name> does not. In traefik gui on port 8080 this service is not shown.

I am running image containous/traefik:experimental

timoreimann · 2017-03-21T09:45:32Z

@dcrystalj if you run into problems, please create a new issue and / or get in touch with the Traefik community on Slack.

Thanks!

alwaysastudent · 2017-04-03T00:07:40Z

@benoitf - Does this support multiple services if they reside on same port ? What if I want to hit two different paths based on the Host header ?

Thanks to Traefik 1.3 now we can use only traefik for separating normal Odoo requests from longpolling ones. See traefik/traefik#1257.

reflog · 2018-02-26T08:12:20Z

Hi! Any chance to get this working on ECS backend?

ldez · 2018-02-26T08:59:58Z

@reflog yes it's in my todo list.

reflog · 2018-02-26T09:03:38Z

@ldez - that's awesome! Is there any way to simulate this behavior right now? I am trying add these two rules (they worked in docker):

      - "traefik.test.frontend.rule=Host:whoami.docker.localhost;Path:/;ReplacePath:/api"
      - "traefik.test2.frontend.rule=Host:whoami.docker.localhost;PathPrefix:/api"

Any suggestion on how do this this in ECS? Basically, if user comes to / , redirect to /api , otherwise, all requests start with /api.

Thanks in advance!

ldez · 2018-02-26T09:09:26Z

@reflog It's not the good place for questions.

Come to the Traefik community Slack

koliyo · 2018-02-27T08:16:36Z

Ignore this, already resolved! Thanks for this feature!

rjchicago · 2018-08-10T13:48:41Z

Tested and using this feature now - thanks!

for other finding this, here was my simple test...

Labels in docker compose:
- traefik.route1.frontend.rule=PathPrefixStrip:/traefik;PathPrefix:/traefik
- traefik.route2.frontend.rule=Host:traefik.docker-swarm.local
- traefik.route3.frontend.rule=Host:test-traefik.docker-swarm.local

Simple verification:
curl -s http://192.168.99.100/traefik/health | jq
curl -s http://traefik.docker-swarm.local/health | jq
curl -s http://test-traefik.docker-swarm.local/health | jq

In Traefik, this shows as this...
