Hi,  
I'm trying to reverse proxy an external GeoServer service using Traefik in combination with an R Shiny Docker Swarm set up. I can get the Shiny app to display as expected, but still unable to map GeoServer as a PathPrefix to localhost on my computer (i'm currently testing this on my laptop).

I'd like to be able to see GeoServer at localhost/geoserver2

Thanks for you advice.

The docker-compose-traefik.yml:

```
       version: "3.7"
       services:
         traefik:
           image: traefik:2.5.3 
           deploy:
             restart_policy:
               condition: any
             placement:
               constraints:
                 - node.role == manager
             labels:
             - "traefik.http.services.traefik.loadbalancer.server.port=80"
             #- "traefik.http.services.traefik.loadbalancer.server.port=443"

             - "--providers.file.filename=/home/shiny/webapps/9c9t/config/rules.yml"
             - "--providers.file.watch=true"
           ports:
             - "80:80"
             - "9020:8080"
             #- "443:443"
           volumes:

           networks:
             - test_net2          
       networks:
         test_net2:
           driver: overlay
           external: true

```

My rules.yml:

```
      http:
        routers:
          router-geoserver:
            rule: "Host(`localhost`) && PathPrefix(`/geoserver2/`)"
            service: service-geoserver
            entryPoints:
              - "web"
        services:
          service-geoserver:
            loadBalancer:
              servers:
                - url: "http://172.17.0.5:8080/geoserver/"
              passHostHeader: false

```

I have also tried replacing the above URL with "[http://localhost:8030/geoserver](http://localhost:8030/geoserver)' which is the published port in the running GeoServer Docker container.

The docker-compose\_shinyapp.yml:

```
     version: "3.7"
     services:
       dataservice:
         image: img_shiny9c9t_v2 
         #ports:
    
         deploy:
           replicas: 5
           labels:
             - "traefik.enable=true"
             - "traefik.http.routers.dataservice.rule=Host(`localhost`)"

             - "traefik.http.services.dataservice.loadbalancer.sticky.cookie.httpOnly=true"
           restart_policy:
             condition: on-failure
           update_config:
             delay: 2s
         volumes:

Hello @richardtc,

Thanks for your interest in Traefik !

I've tried a very basic docker setup to have your service working. It seems that you have a trailing `/` in your rule that makes it impossible to do `curl localhost/geoserver2`. It is accessible through `curl localhost/geoserver2/`.

Many thanks for your quick response.

I'm still having some difficulty with this.

I added the following line to docker-compose-shinyapp.yml under labels:

```
     - "traefik.http.routers.service-geoserver.rule:Host(`localhost`) && PathPrefix(`/geoserver2`)"

```

However, I'm then unable to access localhost in the browser.

I'm not too sure what I should replace 'whoami' in the above line with, but have used 'service-geoserver' (as in the rules.yml file), and maybe that is the problem.

I also removed the trailing / in the rules/yml file:

```
      http:
        routers:
          router-geoserver:
            rule: "Host(`localhost`) && PathPrefix(`/geoserver2`)"
            service: service-geoserver
            entryPoints:
              - "web"
        services:
          service-geoserver:
            loadBalancer:
              servers:
                - url: "http://172.17.0.5:8080/geoserver/"
```

</div>

I also have tried modifying the rules.yml file as follows, but still I'm not able to access GeoServer at localhost/geoserver2:

```
      http:
        routers:
          router-geoserver:
            rule: "Host(`localhost`) && PathPrefix(`/geoserver2`)"
            service: service-geoserver
            entryPoints:
              - "web"
        services:
          service-geoserver:
            loadBalancer:
              servers:
                - url: "http://172.17.0.5:8080/geoserver/"
            deploy:
              labels:
                - "traefik.http.routers.service-geoserver.rule:Host(`localhost`) && PathPrefix(`/geoserver2`)"

```

Perhaps the issue is related to the providers file. Here is the traefik log output:

9c9t\_traefik.1.i6ddka5vkjqd@desktop\_rc | time="2021-12-29T18:35:08Z" level=error msg="Cannot start the provider \*file.Provider: error reading configuration file: /home/shiny/webapps/9c9t/config/rules.yml - open /home/shiny/webapps/9c9t/config/rules.yml:: no such file or directory"

</div>

I'm making some progress having resolved the provider file issue above - the issue I have now is a 'Gateway Timeout' for localhost/geoserver2:

```
 traefik.1.5c8lm74nmeal@desktop_rc | time="2021-12-30T07:44:15Z" level=debug msg="'504 Gateway Timeout' caused by: dial tcp 172.17.0.5:8081: i/o timeout"

```

Would be grateful for any idea to resolve the Gateway Timeout.  
Many thanks.

I see a couple of errors so far:

- You have a typo here `- "traefik.http.routers.service-geoserver.rule:Host(`localhost`) && PathPrefix(`/geoserver2`)"`. It should be `- "traefik.http.routers.service-geoserver.rule=Host(`localhost`) && PathPrefix(`/geoserver2`)"`
- Adding the labels using the `deploy` argument is redundant.

In the [router section](https://doc.traefik.io/traefik/routing/providers/docker/#routers), it states:

> add labels starting with `traefik.http.routers.<name-of-your-choice>.` and followed by the option you want to change

So you can replace `whoami` with "anything".

It says that Traefik cannot reach the dynamic configuration file

> [@richardtc](#):

That because Traefik cannot reach `172.17.0.5:8081`.

Many thanks for the guidance.

When I change the following, I get a 'Not found' browser response for localhost/geoserver2 rather than a gateway timeout.

traefik.http.routers.service-geoserver.rule:Host(`localhost`)  
to  
traefik.http.routers.service-geoserver.rule=Host(`localhost`)

I fixed the provider file (now renamed to traefik-file.yml) as per Traefik documentation.

I also checked the standalone GeoServer Docker container is on the test\_net2 network the same as the Docker swarm:

```
      $ docker network inspect test_net2
      Remove existing network
      $docker network remove
      Create Docker overlay (to connect all containers): 
      $ docker network create -d overlay --attachable test_net2
      To connect standalone container to test_net2 network
      $docker network connect test_net2 geoserver_v1.10_mekong9c9t_v3

```

I also modified the following in the docker-compose-traefik.yml file to make containers discoverable:

```
 providers.docker.exposedbydefault=true"

```

However, I still cannot access GeoServer homepage at [http://localhost/geoserver2](http://localhost/geoserver2)

I'd be grateful for any further suggestions. It seems like it is a network issue but the standalone GeoServer container is on the overlay network?

These are my files again and output from '$ docker inspect test\_net2':

I resolved this, the IP address of the GeoServer container is 10.0.15.2 as per the 'docker inspect test\_net2' output.

I've updated the traefik-file.yml above.

Thanks for your help with this!
