How to install NextCloud via Docker
Install Docker
Create a Docker Compose file
Once you have Docker and Docker Compose installed, create a new file called docker-compose.yml. You can do this in any text editor of your choice. In this file, we will define the Nextcloud service and its dependencies.

net:So what does this docker compose file do?
This file defines four services, nextcloud_db, nextcloud, nextcloud_redis and caddy the reverse proxy. The nextcloud_db service uses the mariadb image to run a MariaDB database container. It also sets the necessary environment variables. The nextcloud service uses the nextcloud image to run the Nextcloud application container. the nextcloud_redis is used for significantly improving your Nextcloud server performance with memory caching, where frequently-requested objects are stored in memory for faster retrieval
Create Caddyfile

Bring up the docker containers
docker compose up -d && docker compose logs -fThis command will start the nextcloud container in detached mode, meaning it will run in the background. and it will show you the logs from nextcloud so you can make sure there were no errors. hit CTRL + C to close the logs.
Stop containers temporarily
This will stop the containers but not delete the temporary network, or remove temporary files etc.
docker compose stopBring down the containers completely
This will stop and remove the containers, but keep the data in the volumes mentioned in docker-compose.yml intact so that your data is not lost.
docker compose downThat’s it! You’ve now installed Nextcloud using Docker Compose. With Docker Compose, you can easily manage and deploy complex applications like Nextcloud with just a few commands.
