✅ I finally got Portainer to work with the Docker LXC Helper Script

[tfriberg]

I could not get Portainer to connect to local environment after having run the Docker LXC helper script via ProxMenux.

1. I uninstalled Portainer that the script provided and instead ran docker run -d -p 8000:8000 -p 9443:9443 --name portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:lts as per the Portainer web site.
2. I also had to(?)/ran nano /etc/sysctl.conf and uncommented sysctl net.ipv4.ip_forward=1
3. With systemctl edit docker I had to(?) / added Environment=DOCKER_MIN_API_VERSION=1.24 to [Service]

After this I could access Portainer at :9443 and it was connected to the local environment.

⚠️ I'm a Docker and Proxmox amateur so these edits might undo/void any security measures the script might take into consideration.
