Problem converting not.header with matcher

[aviv926]

While trying to convert my Caddyfile to caddy-docker-proxy I encountered a problem, I can't convert this section to labels:

mobile.site.mydomain.com {
 # Define non-mobile User-Agent matcher
 @not_mobile {
  not header User-Agent *Mobile*
  not header User-Agent Dart/3.*
  not header User-Agent Dalvik/2.*
 }
 # Redirect non-mobile users to desktop site
 redir @not_mobile https://site.mydomain.com{uri}
 # Proxy mobile users to the mobile backend
 reverse_proxy 127.0.0.1:2741

I tried so many options but none of them worked for example:

  caddy_1: "mobile.site.mydomain.com" # Main domain for the second configuration block

  caddy_1.matcher_0_name: "not_mobile"
  caddy_1.matcher_0_not_0.header: "User-Agent *Mobile*"
  caddy_1.matcher_0_not_1.header: "User-Agent Dart/3.*"
  caddy_1.matcher_0_not_2.header: "User-Agent Dalvik/2.*"

  caddy_1.redir: "@not_mobile https://site.mydomain.com{http.request.uri}"

  caddy_1.reverse_proxy: "{{upstreams http 2741}}"

logs error:

caddy     | {"level":"info","ts":1746624396.4269888,"logger":"docker-proxy","msg":"Process Caddyfile","logs":"[ERROR]  Removing invalid block: Caddyfile:36: unrecognized directive: matcher_0_name\nmobile.site.mydomain.com {\n\tmatcher_0_name not_mobile\n\tmatcher_0_not {\n\t\theader User-Agent *Mobile*\n\t}\n\tmatcher_0_not {\n\t\theader User-Agent Dalvik/2.*\n\t}\n\tmatcher_0_not {\n\t\theader User-Agent Dart/3.*\n\t}\n\tredir @not_mobile https://site.mydomain.com{http.request.uri}\n\treverse_proxy http://172.21.0.6:2741\n}\n\n"}

Can anyone show me the correct way to do this?

Try something like this:

  caddy_1: "mobile.site.mydomain.com" # Main domain for the second configuration block
  caddy_1.@not_mobile.not_0: header User-Agent *Mobile*
  caddy_1.@not_mobile.not_1: header User-Agent Dart/3.*
  caddy_1.@not_mobile.not_2: header User-Agent Dalvik/2.*
  caddy_1.redir: "@not_mobile https://site.mydomain.com{uri}"
  caddy_1.reverse_proxy: "{{upstreams http 2741}}"
