✅ Have you read and understood the above guidelines?

yes

📜 What is the name of the script you are using?

alpine-traefik

📂 What was the exact command used to execute the script?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/alpine-traefik.sh)"

⚙️ What settings are you using?

  • Default Settings
  • Advanced Settings

🖥️ Which Linux distribution are you using?

Alpine

📝 Provide a clear and concise description of the issue.

I've spend whole day trying to enable dashboard that somehow does not returns anything. Browser drops closed connection, so I've managed to check the configuration file and found out that dashboard listens on 8080 under localhost. My container gets ip from dhcp and has other ip address, not localhost. I've run netstat -tuln and it showed that 80 and 443 listens on :::80 and :::443, but the dashboard itself under localhost:8080. I don't think this is a correct behaviour when I was agreed with enabling dashboard and didn't expect that it will be listen inside of lxc container.

Is yaml file correct and this behavior is meant to be or not?

Also traefik --configFile=/etc/traefik/traefik.yaml didn't worked to reload configuration. I had to reboot whole container

🔄 Steps to reproduce the issue.

I'm not familiar with traefik. I know basis of reverse proxy, but never worked with them. I might be wrong in deployment

@tremor021 I think it's because that repo is hidden. I thought this would work. Updated issue

The config file you pasted is the one to create the container. It has nothing to do with traefik the app

Yea. The traefik yaml was neven changed. The cli asked would i like to add dashboard and i said yes. After that i've tried to connect into it and browser said closed connection or something like that. i've checked all opened ports and found out that it listens on localhost. I think it's the problem with configuration file that script generates

This is what helper script generates for static configuration

Seems like they changed a bit the default config.

do:

rc-service traefik stop

remove localhost from localhost:8080 so it just says :8080

then do:

rc-service traefik start

They now create the default config themselves, hence why our script fails. Script makes traefik.yml config file in the /etc/traefik/ directory, but traefik.yaml created by the app takes precedence.
You can also fix your container just by deleting traefik.yaml created by the app.

Anyway, we gonna fix it on a script level. Thanks for noticing this
