What is Nextcloud?
--------------------------------------------------------------------
Nextcloud is a suite of client-server software for creating and using file hosting services. It is enterprise-ready with comprehensive support options. Being free and open-source software, anyone is allowed to install and operate it on their own private server devices. - https://en.wikipedia.org/wiki/Nextcloud

02. Run the following commands in the terminal
# install prerequisites
sudo apt install apt-transport-https ca-certificates curl software-properties-common gnupg-agent -y
# add docker gpg key
curl -fsSL https://download.docker.com/linux/$(awk -F'=' '/^ID=/{ print $NF }' /etc/os-release)/gpg | sudo apt-key add -
# add docker software repository
sudo add-apt-repository "deb [arch=$(dpkg --print-architecture)] https://download.docker.com/linux/$(awk -F'=' '/^ID=/{ print $NF }' /etc/os-release) $(lsb_release -cs) stable"
# install docker
sudo apt install docker-ce docker-compose containerd.io -y
# enable and start docker service
sudo systemctl enable docker && sudo systemctl start docker

Running Nextcloud
--------------------------------------------------------------------
01. Now that Docker is installed, run the following commands to setup the Nextcloud Docker container and run it
# create working directories
mkdir /home/$USER/docker/mariadb -p && mkdir /home/$USER/docker/nextcloud -p
# set owner of working directories
sudo chown "$USER":"$USER" /home/"$USER"/docker -R
# create nextcloud network
docker network create nextcloud
# run the mariadb docker container
docker run -d --name mariadb --network nextcloud --network-alias db -e MYSQL_ROOT_PASSWORD=r00tp@ss -e MYSQL_USER=nextcloud_rw -e MYSQL_PASSWORD=N3xtCl0ud! -e MYSQL_DATABASE=nextcloud -v /home/$USER/docker/mariadb:/var/lib/mysql --restart=unless-stopped mariadb:latest
# run the nextcloud docker container
docker run -d --name nextcloud --network nextcloud -p 8080:80 -e MYSQL_HOST=db -e MYSQL_USER=nextcloud_rw -e MYSQL_PASSWORD=N3xtCl0ud! -e MYSQL_DATABASE=nextcloud -v /home/$USER/docker/nextcloud:/var/www/html --restart=unless-stopped nextcloud:latest
