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. -

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$(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)]$(awk -F'=' '/^ID=/{ print $NF }' /etc/os-release) $(lsb_release -cs) stable"
    # install docker
    sudo apt install docker-ce docker-compose -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
