Apllying middleware from file is not working on "backend" entrypoint, but instead on the http, htpps entrypoint it's working as expected, without configuring something else there...

level=debug msg="Middleware name not found in config (ResponseModifier)" middlewareName=response-headers@file middlewareType=undefined entryPointName=backend routerName=somethingssl@docker

Output of traefik version : ( What version of Traefik are you using? )

Middleware@file not found, when using “custom” entrypoint

You are not using a "custom" entry point in your docker-compose file.

The definitions of your middlewares used by wordpress are missing.

So could you provide a docker-compose related to your root problem.

5

edited...tre problem extends now to http and https entrypoints also. The definitions are in the dynamic_toml posted above.

6

Could provide the definition of sslproxy-headers.

Could you provide a reproducible case, because if you don't provide something that I can reproduce I cannot help you.

7

sorry left it accedentially there...is gone. secure@tls is also gone...this seems to work...

8

Sorry but there are again some missing elements.

So you try to create a real reproducible case in only one docker-compose file (traefik + wordpress) and all files that you use with the file provider.

Use the TLD .localhost to hide your domains.

Have you try to run your example?

Could you provide logs?

11

I tried it again I hope it's working now

12

yes log:

level=debug msg="Middleware name not found in config (ResponseModifier)" entryPointName=backend routerName=wordpresshttp@docker middlewareName=response-headers@file middlewareType=undefined
13

Could you provide the full logs from the start of Traefik.

14

Your example cannot works: the files for the dynamic configuration are missing.

Could you provide a full reproducible example:

  • all files
  • an example that you have tried to run
  • the full logs

this is the dynamic conf toml...i don't know what you need here...

Could you provide the full logs from the start of Traefik.

I reduced your docker-compose file to try to reproduce easily:

  • no swarm
  • no let's encrypt
  • self-sign certs

I don't reproduce your issue.

I think that your issue can be related to the file provider in your context.

See Limitations in File | Traefik | v2.2

Middleware name not found in config (ResponseModifier)

This message appears when middleware is used on a router but it does not exist.

So I think that the problem is related to the reload of the files consumed by the file provider.
As explain in the Limitations we recommend to use directory instead of filename

the 2 configurations works in any kind of format (TOML, YAML,labels, ...) , so your problem is not related to that.
