I have debugged a little more. I created a TOML file: [http.middlewares]
[http.middlewares.rewrite_theme.plugin.theme_changer]
lastModified = true
[[http.middlewares.rewrite_theme.plugin.theme_changer.rewrites]]
regex = "System"
replacement = "ITWORKS"From previous post replaced the line: Removed these lines: Now I am getting this error output: |

Hello, I tried something like this and it works perfectly : version: "3.3"
services:
traefik:
image: "traefik:v2.3"
container_name: "traefik"
command:
- "--providers.docker=true"
- "--entrypoints.web.address=:80"
- "--pilot.token=$TOKEN"
- "--experimental.plugins.theme_changer.modulename=github.com/traefik/plugin-rewritebody"
- "--experimental.plugins.theme_changer.version=v0.3.1"
ports:
- "80:80"
- "8080:8080"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:ro"
whoami:
image: "traefik/whoami"
container_name: "simple-service"
labels:
- "traefik.enable=true"
- "traefik.http.routers.whoami.rule=Host(`whoami.localhost`)"
- "traefik.http.routers.whoami.entrypoints=web"
- "traefik.http.routers.whoami.middlewares=rewrite_theme"
- "traefik.http.middlewares.rewrite_theme.plugin.theme_changer.rewrites[0].regex=Hostname"
- "traefik.http.middlewares.rewrite_theme.plugin.theme_changer.rewrites[0].replacement=Pouet"Do you have any logs informations with your first test ? (by passing --log.level=DEBUG to traefik ) |

Hi youkoulayley, Thanks for the reply. I tried the whoami container also and it works on my system so I am happy that we established that it works via docker labels. However, it will not work with my sonarr container. Docker container compose file sonarr:
image: ghcr.io/linuxserver/sonarr:preview
container_name: sonarr
restart: unless-stopped
environment:
- PUID=$PUID
- PGID=$PGID
- TZ=$TZ
networks:
- $T2_NETWORK
security_opt:
- no-new-privileges:true
volumes:
- $DOCUMENTS/Sonarr:/config
- $DOCUMENTS/Nzbget/Completed:/downloads
- $MEDIA:/media
labels:
- "traefik.enable=true"
- "traefik.http.routers.sonarr-rtr.entrypoints=web"
- "traefik.http.routers.sonarr-rtr.rule=Host(`sonarr.$BASE_HOST`)"
- "traefik.http.routers.sonarr-rtr.service=sonarr-svc"
- "traefik.http.middlewares.rewrite_sonarr_theme.plugin.theme_changer.rewrites[0].regex=System"
- "traefik.http.middlewares.rewrite_sonarr_theme.plugin.theme_changer.rewrites[0].replacement=WORKS"
- "traefik.http.routers.sonarr-rtr.middlewares=rewrite_sonarr_theme"
- "traefik.http.services.sonarr-svc.loadbalancer.server.port=8989"This is the debug output but I did not see anything useful that I could discern |

Here's a setup that is working : version: "3.3"
services:
traefik:
image: "traefik:v2.3"
container_name: "traefik"
command:
- "--log.level=DEBUG"
- "--providers.docker=true"
- "--entrypoints.web.address=:80"
- "--pilot.token=$TOKEN"
- "--experimental.plugins.theme_changer.modulename=github.com/traefik/plugin-rewritebody"
- "--experimental.plugins.theme_changer.version=v0.3.1"
ports:
- "80:80"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:ro"
sonarr:
image: ghcr.io/linuxserver/sonarr:preview
container_name: sonarr
security_opt:
- no-new-privileges:true
labels:
- "traefik.enable=true"
- "traefik.http.routers.sonarr-rtr.entrypoints=web"
- "traefik.http.routers.sonarr-rtr.rule=Host(`sonar.localhost`)"
- "traefik.http.routers.sonarr-rtr.middlewares=rewritesonarrtheme"
- "traefik.http.routers.sonarr-rtr.service=sonarr-svc"
- "traefik.http.services.sonarr-svc.loadbalancer.server.port=8989"
- "traefik.http.middlewares.rewritesonarrtheme.plugin.theme_changer.rewrites[0].regex=System"
- "traefik.http.middlewares.rewritesonarrtheme.plugin.theme_changer.rewrites[0].replacement=WORKS"I see in your configuration that you specify a custom network : networks:
- $T2_NETWORKHave you tried to add this label on the sonarr container : - "traefik.docker.network=$T2_NETWORK" |

I tried a fresh sonarr container and copied all the settings that you referred too. I am still getting a panic error. I have no idea why and I wish there was more debug information as to why it is happening. This is my traefik settings. I did try adding the traefik:
container_name: traefik
image: traefik:latest
restart: unless-stopped
command:
- --global.checkNewVersion=true
- --api.insecure=true
- --entrypoints.web.address=:80
# (Default: error) DEBUG, INFO, WARN, ERROR, FATAL, PANIC
- --log.level=INFO
# Do not expose containers unless explicitly told so
- --providers.docker=true
- --providers.docker.exposedbydefault=false
- --providers.docker.network=$T2_NETWORK
# Traefik Plugins Config
- --pilot.token=$TRAEFIK_TOKEN
- --experimental.plugins.theme_changer.modulename=github.com/traefik/plugin-rewritebody
- --experimental.plugins.theme_changer.version=v0.3.1
networks:
- $T2_NETWORK
ports:
- target: 80
published: 80
protocol: tcp
mode: host
volumes:
- /var/run/docker.sock:/var/run/docker.sock:ro
labels:
- "traefik.enable=true"
- "traefik.http.routers.traefik-rtr.entrypoints=web"
- "traefik.http.routers.traefik-rtr.rule=Host(`traefik.$BASE_HOST`)"
- "traefik.http.routers.traefik-rtr.service=traefik-svc"
- "traefik.http.services.traefik-svc.loadbalancer.server.port=8080"I am experimenting with develop mode for the plugin and added: func (r *rewriteBody) ServeHTTP(rw http.ResponseWriter, req *http.Request) {
wrappedWriter := &responseWriter{
lastModified: r.lastModified,
ResponseWriter: rw,
}
defer func() {
if err := recover(); err != nil {
log.Println("panic occurred:", err)
}
}()
r.next.ServeHTTP(wrappedWriter, req)
bodyBytes := wrappedWriter.buffer.Bytes()
contentEncoding := wrappedWriter.Header().Get("Content-Encoding")
if contentEncoding != "" && contentEncoding != "identity" {
if _, err := rw.Write(bodyBytes); err != nil {
log.Printf("unable to write body: %v", err)
}
return
}
for _, rewrite := range r.rewrites {
bodyBytes = rewrite.regex.ReplaceAll(bodyBytes, rewrite.replacement)
}
if _, err := rw.Write(bodyBytes); err != nil {
log.Printf("unable to write rewrited body: %v", err)
}
}The "additional" error information I got from the log is but not sure what this signifies: |
|
I see you have an image with the latest tag : Are you sure your docker has downloaded the very latest version of traefik ? |
|
Tried that and still getting the panic error. |
|
Could you send me all the logs since the Traefik startup with the panic stack in DEBUG level ? |
|
See attached log. I removed my token in the log. Is there a way to get a version of the plugin that outputs more information since this is a "panic" event... Just shooting ideas. Thank you so much for your continued help. |

I able to reproduce, so I confirm the issue. |

Hi,
I am trying to get this plugin to work using docker labels. I am not having any success to get it working. For testing, I am trying to replace 'en' to 'es' in the page but cannot get this to work. My goal is to use this to change the theme.
Static Config:
Dynamic Config:
Thank you for any help / direction.
