I have a http server running in a docker. Accessing the server at / redirects it to /web. This works fine locally. I have setup traefik to connect to the docker through xxxxxxx.com domain. However, this results in a 404 page not found but when I try xxxxxxxx.com/web it works. How does traefik handle this kind of redirects? Thanks in advance.
Here's my docker-compose.yml file:

I've got my docker environment setup using traefik and I've got two services running at the moment.
I'm using Google OAuth for authentication which redirects to my web application with auth-code. The redirect URL isn't allowed anything but localhost or localhost:<any-port> or any CDN. I've setup my docker for http://portal.local.
I now want http://localhost/user/googleLogin?code=xxxxxxxxxx to be translated to http://portal.local/user/googleLogin?code=xxxxxxxx for further processing of authentication.
Right now, I'm having to manually change localhost to portal.local in browser URL after it gives site not found error, which then takes me to further processing.
Below is my docker-compose.yml file.

I've tried to use multiple router rules to listen to both localhost and portal.local using regex/replacement middlewares as well but that stops the service at all and gives 404 error.
I'm trying to setup docker networks with traefik on an existing website.
Before my tries, it had this:

It works fine.
Then I tried doing this :
docker network create web
And in the yml:
networks:
web:
external: true
internal:
external: false
For php-http:
networks:
- internal
- web
and (I tried without and with it)
- "traefik.docker.network=web"
In database and mailserver :
networks:
- internal
In traefik:
networks:
- web
and (tried without and with it)
- "traefik.docker.network=web"
It didn't work at all, my website wasn't accessible anymore.
Then as said there : https://doc.traefik.io/traefik/user-guides/docker-compose/basic-example/
I tried :
networks:
web: {}
Then in php-http and traefik:
networks:
- web
It didn't work either. Their example (with whoami) works on my server. (Tried with a local curl). Like always, this makes me hate sysadmin very much, does anyone has any clue on what's wrong there? It doesn't make anysense to me. I followed everything, tried everything.
Thank you
Greetings Stack Overflow,
I have a RespberryPi4B, on which I installed Ubuntu 20.
(Linux ubuntu 5.4.0-1034-raspi aarch64 - Ubuntu 20.04.1 LTS)
On this Pi I want to install several Applications for my local use only.
To be able to have multiple Applications exposed, I use Traefik as a Proxy.
To easier deploy the Applications, I use Docker and Docker-Compose
Already up and running I have a Nextcloud instance, which works just fine.
Now I want to add FireflyIII as an Application, but the routing does not comply, and greets me with "Bad Gateway".
Here's what I have
The following docker-compose.yml for my Nextcloud works like a charm:
version: '3.3'

While knowing that this configuration, and these traefik labels work, I would assume, that the following docker-compose.yml, now for FireflyIII would work as well. And while the container spins up without any visible issues - I can see in the container logs, that the applications connects to the database and prepares everything - the access via browser is not possible - I get a Bad Gateway.
This is my FireflyIII's docker-compose.yml
version: '3.3'
services:
fireflydb:

- "traefik.docker.network=proxy"
networks:
- proxy
- default
volumes:
firefly_upload:
firefly_db:
networks:
proxy:
external: true
The only difference between the Traefik Labels is, that I don't need the replacepathregex labels for firefly, and that I changed the Hosts and application names:
nextcloud.mydomain.com -> firefly.mydomain.com
nextcloud-app/nextcloud-app-secure -> firefly-app/firefly-app-secure
I just don't understand yet, why the "same" configuration behaves differently.
The Traefik container logs don't throw any errors.
A note about the SSL Certificates, since the applications are run in my local network, and I edit my local hostfile to access the application via browser, the SSL renewal isn't possible, I am aware of that. I currently work around it by manually renewing on a different server and copying the cert to my Pi. Quick and dirty, but works for now.
For completeness, here's my Traefik's traefik.yml, docker-compose.yml and dynamic_conf.yml:

The only thing I could think of, might be a problem with the internal Ports.
But I don't know enough about traefik and docker yet, to say for sure.
I appreciate any hints and suggestions for improvement.
At first glance I'd recommend to change the port to 8080:
version: '3.3'
services:
# [...]
firefly:
labels:
#
- "traefik.http.services.firefly-app.loadbalancer.server.port=8080"
# [...]
The firefly-iii-Image you're using is based on their BaseImage which's README.md says:
Basically, I use the 7.4 Apache image with some minor changes.
And one change is:
Switch to port 8080
I had two container frontend (nginx :80) and backend (nodejs :3000).
I'm trying to redirect all path to my frontend : localhost/* to my frontend
Except one path to my backend API : localhost/v1/* to my backend
I secure my database container (mongodb) by allowing only communication with my backend
Here is my docker-compose.yml (I'm only using this)

The problem is...
If the frontend (backend and traefik too) is turned on
the paths to localhost/* work (this is what I want),
but the paths to localhost/v1/* don't work (Problem here!).
If the frontend is turned off but traefik and backend is turned on
the paths to localhost/* don't work (of course, that's right),
but the paths to localhost/v1/* work (of course, this is what I want).
I've tried a lot of solutions but nothing seems to work the way I want it to.
What did I misunderstand?
Thanks for helping,
Have a nice day
Try to add the following labels to the backend service
- "traefik.http.routers.backend.rule=Host(`servicex.me`) && Path(`/v1`)"
and frontend
- traefik.http.routers.frontend.rule=Host(`servicex.me`)
you also need to add this line to your /etc/hosts
127.0.0.1 servicex.me
and make sure that you stop and start the services

BTW, why do you need both traefik and nginx (Both are doing the same job), it would be better if you can replace one with another.
I added this label to my containers
traefik.docker.network=traefik-network
It works fine now
I'm trying to proxy the pgAdmin web interface using segment URLs. But I have some problems with this.
When I'm accessing the browser with the following URL -> http://localhost/pgadmin, it redirects me to the following URL -> http://localhost/login?next=%2F. This is the internal routing of pgAdmin.
I want routing to be next http://localhost/pgadmin/login?next=%2F.
Could you tell me how can I achieve this.
