Hello,
I tried to install SWAG with a wildcard let’s encryot certificat. I use the same example like in the SWAG Setup web page, but I have a message when I launch the docker without next information bottom :

Please set the DNSPLUGIN variable to one of the following:

This is my config :

  swag:
    restart: always
    container_name: swag
    image: lscr.io/linuxserver/swag:latest
    cap_add:
      - NET_ADMIN
    ports:
      - "443:443"
      - "80:80"
    volumes:
      - /docker/swag:/config
    environment:
      - PUID=1015
      - PGID=1001
      - TZ=Europe/Paris

      - SUBDOMAINS=wildcard
      - VALIDATION=dns

I tried a few things and can’t reproduce the issue. Can you try running certbot plugins --authenticators and posting the whole output here?

Edit:
From inside the container, can you run echo $PATH and post the output here?
To get into the container you might need to run docker exec -it swag bash on the host.

Did you create/deploy this container with portainer or any other docker UI?

Hello, i encountered the same problem while using swag with portainer. It seems that something’s got changed with the container’s path? As soon as i removed the PATH environment variable from the container and let it recreate it, everything got fixed.

Thanks!

breaking paths is a feature of portainer according to their github issues.

note that we do not support or recommend using portainer to deploy containers.
