Portainer setup

File permissions

If the correct file permissions aren't set in the persistent volume, Portainer won't be able to function properly. Docker is run by the pi user so we'll ensure pi can read/write into the persistent volume by changing the group ownership to the pi group.

1. sudo chown -R root:pi /mnt/glusterfs/portainer
2. sudo chmod -R 775 /mnt/glusterfs/portainer
3. sudo chmod g+s /mnt/glusterfs/portainer (Ensures all future content in the folder will inherit group ownership)

portainer-stack.env

Make sure portainer-stack.env is in the same directory as the portainer.yml file

Run Portainer

docker stack deploy --compose-file=/mnt/glusterfs/configs/portainer/portainer.yml portainer

Now, you can do all of your setup and configuration of stacks/containers/networks/etc with Portainer. Or you can do it on the command line. If you start a stack/container etc from the command line, Portainer will not be able to stop/restart it through its UI. You would have to do it at the command line. Otherwise, Portainer has full info on the Swarm.
