Nextcloud installed with stacks on Portainer in about 6 minutes.
This is more or less identical to Macon's guide on the forum here.
It works ok expect for the things not working as mentioned in your video 
I found that the gallery app does not add any previews in "your photos" from drives that i included through the "external storage" addon (using the type "local" share in there). This makes it more or less useless for me. Not sure if that is in general not working with this docker image for now, but it seems to be the case.
Furthermore i would suggest to add redis to the installation to speed up nextcloud.
This can be done by adding the following to the stack script:
redis:
image: redis
container_name: redis
volumes:
- /srv/dev-disk-by-label-SSD_Data/appdata/redisDocker:/data #--> needs to be changed to your config
restart: unless-stoppedThe nextcloud config must be adapted to use redis as described here: https://docs.nextcloud.com/ser…aching_configuration.html
