I want to modify the endpoints of my URL, while it goes from traefik to one of my containers. What I want is this.
My URL looks like this - http://backend/asd and it should point to one of my containers with different endpoint like this - http://asd/dfg
What I tried -
asd:
image: asd
container_name: "asd"
labels:
- "traefik.backend=asd"
- "traefik.frontend.rule=Host:backend;PathPrefixStrip:/asd,PathPrefix:/dfg"
- "traefik.frontend.entryPoints=http"
- "traefik.enable=true"
- "traefik.port=80"
But this didn't work. Any suggestions are welcome.
Regards,
Ashutosh
Are you including a Traefik-docker-image in your docker-compose, like so?
traefik:
image: traefik
ports:
- 8080:80
volumes:
- /var/run/docker.sock:/var/run/docker.sock
command:
- "--docker"
For your path-replacement "/asd" -> "/dfg", Traefik's ReplacePath-modifier should do the trick. This following docker-label is the only, you will need:
labels:
- "traefik.frontend.rule=Path: /asd; ReplacePath: /dfg"
Having this setup, doing
curl http://localhost:8080/asd
should return the HTTP-response from your "asd"-container on path "/dfg"

I try to proxy a dockware container through traefik.
The error is an internal server error (500).
Is it necessary to change the domainname at all? If so, how can I change the domain name?

If you get an internal server error, please check the server logs.
You can manually change the domain name in the sales_channel_domain table.
The problem might be, that SSL is terminated on traefik and Shopware does not detect this - if this is the problem, you might need to set the TRUESTED_PROXIES variable to the IP of your traefik server/container.
Since upgrading to Portainer v2, the icons would suddenly not load anymore. I can still access Portainer (which is proxied by Traefik), but after a bit of testing, I noticed, only / would be forwarded. If a path was given, Traefik would throw a 404 error. This is a problem because Portainer loads the fonts from eg. /b15db15f746f29ffa02638cb455b8ec0.woff2.
There is one issue about this on Github, but I don't really know what to do with that information: https://github.com/portainer/portainer/issues/3706

What do I have to change to make Traefik be able to forward the paths so that Portainer can load the icons?
Could you try flush your DNS Cache?
In Chrome 'chrome://net-internals/#dns' into URL bar and pressed enter.
Then click on 'Clear host cache'
Then refresh your portainer page
I noticed that there is also an Alpine version of Portainer.
After switching to that (image: portainer/portainer-ce:alpine), the icons seem to be working again. I don't know what the issue is with the regular image, but this solves it for now.
PS: I had tried to use the Access-Control header on Traefik, but that didn't help. I guess it's a problem with Portainer's code itself.
If someone else is facing this issue, I resolved this by deleting my Browser Cache or just do a full Refresh with CTRL+Shift+R
I have been using Traefik as a reverse proxy for several containers managed through docker compose. It has been working well but I'm having some difficulty getting graylog running properly behind it.
This config (excerpt of the complete file, removed irrelevant services) works for me
version: '3'
services:
traefik:
image: traefik
command: --docker
networks:
- web
ports:
- "80:80"
- "8080:8080"
- "443:443"
volumes:
- /var/run/docker.sock:/var/run/docker.sock
graylog:

environment:
- GRAYLOG_PASSWORD_SECRET=somepasswordpepper
- GRAYLOG_ROOT_PASSWORD_SHA2=somestuffhere
- GRAYLOG_HTTP_BIND_ADDRESS=0.0.0.0:9000
- GRAYLOG_HTTP_EXTERNAL_URI=http://graylog.localhost/
links:
- mongodb:mongo
- elasticsearch
depends_on:
- mongodb
- elasticsearch
networks:
- web
- default
ports:
- 9000:9000
- 1514:1514
- 1514:1514/udp
- 12201:12201
- 12201:12201/udp
labels:
- "traefik.docker.network=web"
- "traefik.web.frontend.rule=Host:graylog.localhost"
- "traefik.protocol=http"
- "traefik.port=9000"
- "traefik.enable=true"
I can then access graylog in my browser at http://graylog.localhost/
The problem occurs because I can't use domains like this in my staging env. What I have had to use is paths rather than domains e.g. the swagger service in my staging env is defined as
swagger:
image: swaggerapi/swagger-ui
environment:
SWAGGER_JSON: /swagger/staging-openapi.yaml
BASE_URL: /swagger
volumes:
- /home/ubuntu/src/carelink_swagger_service:/swagger
networks:
- web
- default
labels:
- "traefik.docker.network=web"
- "traefik.frontend.rule=Host:my.staging.domain.org; PathPrefix: /swagger"
- "traefik.protocol=http"
- "traefik.port=8080"
- "traefik.enable=true"
and I access services like this https://my.staging.domain.org/swagger/
Trying to adopt this approach for graylog
graylog:
image: graylog/graylog:3.0
environment:
- GRAYLOG_PASSWORD_SECRET=somepasswordpepper
- GRAYLOG_ROOT_PASSWORD_SHA2=somestuffhere
- GRAYLOG_HTTP_BIND_ADDRESS=0.0.0.0:9000

- "traefik.protocol=http"
- "traefik.port=9000"
- "traefik.enable=true"
and I get the following errors
I have gone through this Q/A, similar entries on the graylog forums etc. but I feel like I'm chasing my tail.
It's for Traefik 2.x but I think that you'll manage to convert your rules:
labels:
- "traefik.http.routers.graylog.rule=PathPrefix(`/graylog`)"
- "traefik.http.routers.graylog.middlewares=graylog3#docker,graylog2#docker,graylog#docker"

- "traefik.http.middlewares.graylog2.redirectregex.regex=^(.*)/graylog$$"
- "traefik.http.middlewares.graylog2.redirectregex.replacement=$$1/graylog/"
- "traefik.http.middlewares.graylog.replacepathregex.regex=^/graylog/(.*)"
- "traefik.http.middlewares.graylog.replacepathregex.replacement=^/$$1"
- "traefik.http.routers.graylog.service=graylog"
- "traefik.http.services.graylog.loadbalancer.server.port=9000"
- "traefik.docker.network=traefik"
i need redirect a specific /path, i write this compose:
web1:
image: httpd
labels:
- "traefik.backend=httpd"
- "traefik.frontend.rule=Host:www.example.com"
- "traefik.port=80"
web2:
image: nginx
labels:
- "traefik.backend=nginx"
- "traefik.frontend.rule=Host:www.foobar.com"
- "traefik.port=80"
app:
image: custom/image
labels:
- "traefik.backend=app"
- "traefik.frontend.rule=Host:www.example.com,www.foobar.com; PathPrefixStrip:/app"
- "traefik.port=80"
When i go to http://www.example.com/app and http://www.foobar.com/app i need go into container app, but work only if i insert a / at the end of URL:
http://www.example.com/app not work
http://www.foobar.com/app not work
http://www.example.com/app/ work
http://www.foobar.com/app/ work
I have already a version of this app that work with an apache alias, I suppose it's not a problem of the app
Thanks
I've found solution here: https://github.com/containous/traefik/issues/563#issuecomment-421360934

I use traefik without traefik.toml, only a docker-compose.ymal file. I've managed to do whatever I want except one thing : automatically redirect one service from http to https.
Is it possible ?
Here is my docker-compose (extract)

Try to add this to the command:

instead of
