How to use rancher2 behind traefik2 - traefik

i'm trying to set up rancher2 behind a proxy traefik2 with docker-compose, but after several tries and days, i've alway a refused connection on https://rancher2.docker.localhost.
I try to setup an nginx container behind traefik2 and there is no problem expect with https.
Someone can show me how to solve this problem (rancher2 behind traefik2)

Dockware with Traefik

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.

Portainer doesn't show icons anymore since upgrading to v2 (Traefik Proxy)

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

Routing requests to containers based on path?

When a request comes through to my domain I want all /snap requests to be forwarded to my thumbor container along with the path. I can't seem to get this working I've tried many different modifiers.
So for example any request to https://addmysnap.local/snap/image/3234234234/profile.jpg gets routed to the thumbor container as /image/some-other-stuff/3234234234/profile.jpg.
The some-other-stuff part will be string that allows me to watermark the image.
Here's what I've got so far ...
thumbor:
image: minimalcompact/thumbor:latest
restart: always
networks:
- web
- default
volumes:
- ./data:/data
labels:
- "traefik.enable=true"
- - "traefik.basic.frontend.rule=Host:addmysnap.local,ReplacePathRegex: ^/snap/(.*) /$${1}"
- "traefik.basic.port=80"
environment:
UPLOAD_ENABLED: 1
This doesn't work though and I the following error:
thumbor_1 | 2018-09-29 18:16:44 thumbor:WARNING Malformed URL: /snap/image/051a30f09fe340cbac13e9d58d09bee4/image.jpg
Not sure why it's malformed, or why /snap is being passed through.
Any ideas how to do this?

400 Error HTTP GET Request between Docker Containers with HTTPURLConnection

I got two Containers defined in a docker-compose file:
tomcat_webserver_api:
image: tomcat:8
volumes:
- ./API/Docker/API.war:/usr/local/tomcat/webapps/API.war
ports:
- "8080:8080"
depends_on:
- mysql_database
tomcat_webserver_anwendung:
image: tomcat:8
ports:
- "8081:8080"
volumes:
- ./Anwendung/Docker/Anwendung.war:/usr/local/tomcat/webapps/Anwendung.war
depends_on:
- tomcat_webserver_api
environment:
API_HOST: tomcat_webserver_api
API_PORT: 8080
Now i want to access the URL http://tomcat_webserver_api:8080/API/restaurants/Wochentag from Inside the Java Web Application with an HttpURLConnection.
Issue: It returns an 400 Error
java.io.IOException: Server returned HTTP response code: 400 for URL: http://tomcat_webserver_api:8080/API/restaurants/Wochentag
The Code is like that (The Headers are nearly the same when i try to connect to the URL via curl - this works inside the container huh):
URL api = UriBuilder.fromUri("http://" + "tomcat_webserver_api" + ":" + "8080" +"/API/restaurants/RestaurantSpeisen").build().toURL();
System.setProperty("http.agent", "curl/7.52.1");
HttpURLConnection connection = (HttpURLConnection) api.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("Host", "localhost");
connection.setRequestProperty("User-Agent", "curl/7.52.1");
connection.connect();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
If i try to connect to http://172.20.0.3:8080/API/restaurants/Wochentag i got an 200-ok HTTP Response Code and the JSON-Data.
If i exec the API Container and inspect the logs i can see the 400 GET-Request.
Why is this happen?
http://172.20.0.3:8080/API/restaurants/Wochentag - Works
http://tomcat_webserver_api:8080/API/restaurants/Wochentag - Won't Work but not with an 404 Error
I have had the same issue as you, apparently underscore are not allowed as virtualhost, try to remove it, for example, use just tomcatwebserverapi, that should fix your problem.
See Can (domain name) subdomains have an underscore "_" in it? for more information about valid letters in hostnames.
Please give explicit container names a try:
tomcat_webserver_api:
image: tomcat:8
container_name: tomcat_webserver_api
volumes:
- ./API/Docker/API.war:/usr/local/tomcat/webapps/API.war
ports:
- "8080:8080"
depends_on:
- mysql_database
tomcat_webserver_anwendung:
container_name: tomcat_webserver_app
image: tomcat:8
ports:
- "8081:8080"
volumes:
- ./Anwendung/Docker/Anwendung.war:/usr/local/tomcat/webapps/Anwendung.war
depends_on:
- tomcat_webserver_api
environment:
API_HOST: tomcat_webserver_api
API_PORT: 8080
The "local only" configuration needs explicit container names to activate Docker's name lookup mechanism. In Swarm mode you wouldn't need to set container names.

Traefik not working with more than 3 ports exposed

I'm trying to get email service working with traefik. I need to expose 25, 100, 143.. etc.
But traefik only works with <= 3 ports. If I add more than 3, it it stopped working.
This is my sample config:
networks:
- traefik-net
environment:
- HTTPS=OFF
deploy:
placement:
constraints: [node.role == manager]
restart_policy:
condition: on-failure
replicas: 1
labels:
- "traefik.backend=mail"
- "traefik.port=80"
- "traefik.frontend.rule=Host:mail.mydomain.com"
- "traefik.docker.network=traefik-net"
- "traefik.mail.port=80"
- "traefik.mail25.port=25"
- "traefik.mail110.port=110"
- "traefik.mail143.port=143"
- "traefik.mail465.port=465"
- "traefik.mail587.port=587"
- "traefik.mail993.port=993"
- "traefik.mail995.port=995"
I didnt see anything unnormal in mail and traefik service log.
Can anyone help me? Thank in advance and sorry for my bad English.
Many thanks for you interest in the project.
Thanks to the addtional information you gave on Github and after analyzing your problem, it appears you try to expose in HTTP ports which have to be accessed inSMTP(S), POP3(S) and IMAP(S) (which are over TCP).
Currently Træfik is only a HTTP Reverse Proxy and you can't do TCP calls through it, your use case can't work for the moment.
