Install Nextcloud in docker with mariadb, redis, cron and caddy.

1. Enter the folder caddy/certs

2. Create a self signed certificate with this command

   openssl req -newkey rsa:4096 -x509 -sha512 -days 365 -nodes -out certificate.pem -keyout privatekey.pem

1. Set the port you want to use to access Nextcloud (in this example the port is 1201)

   In the docker-compose.yml file

   ports:
     - 1201:1201

   and in the caddy/Caddyfile

   :1201
   tls /etc/caddy/certificate.pem /etc/caddy/privatekey.pem
   reverse_proxy nextcloud:80
   

2. Set the database and redis passwords

3. Change the memory limits to something that suits your needs

   mem_limit: "256M"

4. Set the local folder you want to use for the Nextcloud data (both in nextcloud and in cron)

   - /mnt/Volume/nextcloud/:/var/www/html/data

5. Set the domain name from which you'll access nextcloud (if you are using a service like dynds add dyndns.org or the domain you are using)

   - NEXTCLOUD_TRUSTED_DOMAINS=$YOUR_DOMAIN$

   If you want to access Nextcloud only from localhost you can remove the line.

Use this command to create and start all the containers

docker compose up -d

To run occ commands

docker exec -ti --user www-data nextcloud /var/www/html/occ COMMAND
