Official examples here

There are several options, default recomendation is apache. Alternative is php-fpm as a stand alone container with either apache or ngnix. Apache with php as a module is used in this setup.

Four containers are spin up

nextcloud-db - mariadb database where files and users meta data are stored
nextcloud - the nextcloud
nextcloud-redis - in memory data store for faster and responsive interface
nextcloud-cron - for being able to run maintnance cronjobs

Two persinstent storages

nextcloud-data bind mount - nextcloud app storage with web server and the works
nextcloud-data-db bind mount - database storage

Reverse proxy

Caddy v2 is used, details here

Caddyfile

{
    # acme_ca https://acme-staging-v02.api.letsencrypt.org/directory
}

nextcloud.{$MY_DOMAIN} {
    reverse_proxy {
        to nextcloud:80
    }
}

First run

Extra info

check if redis container works
exec in to redis container: docker container exec -it nextcloud-redis /bin/sh
start monitoring: redis-cli MONITOR
in browse start browsing files on the nextcloud, there should be lot of activity in the monitoring
check if cron container works
in settings > administration > basic settings
Background jobs should be set to Cron and the last job info should never be older than 10 minutes
- in settings > administration > overview
