Updating Portainer

From Proxmox:

docker stop portainer
docker remove portainer
docker pull portainer/portainer-ce:latest
docker run -d -p 8000:8000 -p 9000:9000 -p 9443:9443 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v /config/portainer:/data portainer/portainer-ce:latest

IF YOU ACCIDENTALLY UPGRADE TO EE (Business Edition):

docker stop portainer
docker run -it --name portainer-database-rollback -v /config/portainer:/data portainer/portainer-ee:latest --rollback-to-ce
docker run -d -p 8000:8000 -p 9000:9000 -p 9443:9443 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v /config/portainer:/data portainer/portainer-ce:latest
