Issue with Path Frontend Rule in Docker Swarm #2278
Description
Do you want to request a feature or report a bug?
BUG
What did you do?
I was configuring a couple of backends that were going to be accessed with a Specific Path on the default domain.
Our Environment is Docker Swarm.
We are deploying all containers via stack files
traefik has been deployed (via stack, whose configuration is futher down), and is part of the proxy network to which all stacks are deployed into.
The labels we added to one of the stack files are like this:
labels:
- "traefik.port=8092"
- "traefik.docker.network=proxy"
- "traefix.protocol=http"
- "traefik.tags=solr-update"
- "traefik.backend=solr-update"
- "traefik.frontend.rule=Path:/solr-update"
Note that when we deploy a stack with a specific Host entry, it works fine.
I have tried adding a HOST entry as part of the traefik.frontend.rule, but that did not work.
What did you expect to see?
I expected to see a working http connection to the container.
What did you see instead?
I saw a 404 Not Found.
Here are the results of curl connections to the container:
curl -v http://10.0.0.10:8092/solr-update/healthcheck
