Running Nextcloud in Docker on Linux 🌱

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

Installing Docker

1. Log into the Linux based device
2. 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
   # add the current user to the docker group
   sudo usermod -aG docker $USER
   # reauthenticate for the new group membership to take effect
   su - $USER

Running Nextcloud

1. 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
2. Open a web browser and navigate to http://DNSorIP:8080
3. The Nextcloud setup screen should be displayed
4. Enter a username and password
