traefik 2.2 reverse proxy https not showing my container

Question

I am setting up a test environment with traefik v2.2 in docker. I setup a docker network named traefik, with a test web container. I can see my dashboard if I navigate to https://test.com , however I cannot see my container when I navigate to the paths as setup by the rules (ie https://test.com/myapp )

In the dashboard, everything looks ok in status, the myapp container's internal ip shows up, the routers and https entrypoint are fine.

If I go to https://test.com/myapp it gives an customized 404 page "Error code explanation: 404 = Nothing matches the given URI. " If I go to https://test.com/somenonexistantpath it gives me a regular 404 not found message

I have tried changing the Host rules. I added traefik.docker.network=traefik to the container labels in case they were not on the same network as the traefik container, and verified I could reach http://myapp:80 from inside the traefik container. The host rule looks correct according to the traefik v2 documentation, so I am wondering if I am missing anything.

I did test out moving the test.com Host rule to myapp and that was able to reach the test site, so it seems like I am missing something with paths

Below is my docker-compose file, the config file dynamic-traefik.yaml only has the tls info

version: '3.3'

networks:
  traefik:
    external: true

Answer 1

您需要为 myapp 路由器指定优先级并使其更高，以便首先处理

Answer 2

您的最后一行代码有拼写错误。

- "treafik.docker.network=traefik"

Answer 3

Step 1. Check service logs to find out the reason Ex: something_traefik.1.3e5t2fvcipex@ip-xx-xxx-xx-21 | 2021/07/15 15:46:14 command traefik error: failed to decode configuration from flags: field not found, node: swarmmode \\

$docker service logs _traefik

Step 2. With traefik v2.x, you need to change "command" section in yaml file to look like below.

command: - --providers.docker=true
- --providers.docker.constraints=Label( traefik.constraint-label , ${DOCKER_STACK} )
- --providers.docker.exposedByDefault=false
- --providers.docker.swarmmode=true
- --provider.docker.watch=true
- --api.insecure=true
- --log.level=debug
- --entrypoints.http.address=":xxx"
