Modify Portainer Container

Does anyone know if there's a way to modify the configuration of the Portainer container that is installed with Docker under OMV-Extras? I've tried Duplicate/Edit from within Portainer, but the container doesn't start back up, and the changes don't stick. I'm trying to add the "--no-auth" command to the configuration to disable authentication because I intend to use http auth instead.

Thanks.

That's a really good suggestion. I don't know why I didn't think of something so obvious. I'll remove the Portainer container via OMV-Extras, and add a new one to my Docker compose file. Trying it out now...

Well, the new Portainer container is working fine, but the --no-auth command did not work at all. At least I can control the config now, and I'll do some more research. Thanks for the help.

I got it to work with the --no-auth command. Here's my Docker compose section:

portainer:
    container_name: portainer
    environment:
        - PGID=1000
        - PUID=1000
    image: portainer/portainer
    networks:
        - lan # Pre-defined Docker network
    ports:
        - 9000:9000
    command:
        - "--no-analytics"
        - "--no-auth" # I needed to put it on a separate line
    restart: always
    volumes:
        - '/etc/localtime:/etc/localtime:ro'
        - '/var/run/docker.sock:/var/run/docker.sock'
        - '/config/portainer:/data'

This is nice because I can use http auth via my LetsEncrypt container, and I don't get hit with another authentication prompt.
