docker volume create portainer_data
Will return name of container.
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 portainer_data:/data portainer/portainer-ce:2.21.5
This adds port 9000, which isn't used by default. This allows Portainer to be accessed through HTTP instad of HTTPS.
