Docker AIO configuration
The docker init:
sudo docker run --init --sig-proxy=false --name nextcloud-aio-mastercontainer --restart always --publish 8080:8080 --env APACHE_PORT=11000 --env APACHE_IP_BINDING={public_static_ip_NC} --env APACHE_ADDITIONAL_NETWORK="nextCsite" --env SKIP_DOMAIN_VALIDATION=false --volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config --volume /var/run/docker.sock:/var/run/docker.sock:ro ghcr.io/nextcloud-releases/all-in-one:latest
I did a sketch of my layout but it is quite basic.
I would like to point out that are already different tutorials about adding the AIO’s docker and people dumb as I am, might get confused. Please help me to regain my NC.
