I often see people mention the Portainer project and how it’s useful, but I never hear any reason to use it other than as a more user friendly front end to service management.

So is there any particular feature or reason to use portainer over docker’s CLI? Or is it simply a method of convenience?

This isn’t only strictly for self hosting, but I figure people here would know better.

    What works for me:

    Networks first in docker-compose

    Gluetun first in Services, uses the network I set for it and the stack

    Everything else goes below it, relying on the gluetun CONTAINER (I plan to have another stack running gluetun for other reasons so having it check the service is a no go for me) to be running in a HEALTHY state

    All are set to restart: unless-stopped except gluetun, which is never

    The expected behaviour is that containers will always wait for gluetun to report that it’s healthy before trying again to restart. Should gluetun fail and crash for any reason it won’t reboot and potentially fuck itself up harder, and no services will be able to start because it’s not reporting healthy.

    This works perfectly in portainer and should when running docker-compose up, but for me it took portainer to work. Saw someone somewhere mention it has some sort of priority handling override built into it that docker itself doesn’t, meaning it’s less likely to fuck that lind of thing up, but idk how true it is

    I’ll see if I can remember to snag a couple snips of my YAML to make it more clear

        Ok, had my wife send me the file from my network

        networks:
          main-network:
            name: ${COMPOSE_PROJECT_NAME}
            attachable: true
            ipam:
              driver: default
              config:
                - subnet: configure
                  ip_range: this
                  gateway: yoself
        
        services:
          # Gluetun - <https://github.com/qdm12/gluetun>
          gluetun:
            image: qmcgaw/gluetun
            container_name: gluetun
            networks:
              - main-network
            cap_add:
              - NET_ADMIN
            environment:
              - PUID=${PUID}
              - PGID=${PGID}
              - TZ=${TZ}
              - VPN_SERVICE_PROVIDER=custom
              - VPN_TYPE=wireguard
              - VPN_PORT_FORWARDING=true
              - VPN_PORT_FORWARDING_PROVIDER=protonvpn
              - WIREGUARD_ADDRESSES=use your own
              - WIREGUARD_ALLOWED_IPS=0.0.0.0/0
              - WIREGUARD_PRIVATE_KEY=nope
              - WIREGUARD_PUBLIC_KEY=69420
              - WIREGUARD_DNS=
              - VPN_ENDPOINT_PORT=
              - VPN_ENDPOINT_IP=
            volumes:
              - ${DOAPPDAT}/gluetun:/gluetun
        

        I left in the wireguard stuff without my details because for me Gluetun refused to work when setting the exact same info to wg0.conf, so I define it in my compose

        Then, services that rely on gluetun go below and look like:

        # qBittorrent - <https://hub.docker.com/r/linuxserver/qbittorrent>
        qbittorrent:
          container_name: qbittorrent
          network_mode: container:gluetun
          image: lscr.io/linuxserver/qbittorrent:latest
          depends_on:
            gluetun:
              condition: service_healthy
          restart: unless-stopped
        
        

        Works perfectly when I run it through portainer

          It worked. Muahaha it worked. Thank you so much. I still have so much to learn. But one click and repulled and redeployed. The only change I needed in my config was to add.

          depends_on:
              gluetun:
                condition: service_healthy
          

          Into each container that was controlled by gluetun

            It took me too long to get everything working myself because people love to share shit exclusively in CLI format and look down at anyone who asks for YAML it seems, so I’m always glad to pass it on

            (I can understand CLI, but the ADHD brain finds YAML much easier for documentation purposes and it surprises me how many people seem to disagree)
