Setting up Nextcloud in Docker with MariaDB

We are starting out with a per installed server with docker.

First thing that we need to do is update the server to we are using Ubuntu 20.04

sudo apt update && sudo apt upgrade -y

With the server updated it is time to get to the project the first part of the project that we are going to be working on is the "control file" this is a .ymal file that will tell docker and docker compose for you would like to set up your apps that you will be using for your project.

sudo nano docker-compose.yml

version: '3.8'

services:
  db:
    image: mariadb:latest
    container_name: nextcloud_db
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
      - MYSQL_DATABASE=${MYSQL_DATABASE}
      - MYSQL_USER=${MYSQL_USER}
      - MYSQL_PASSWORD=${MYSQL_PASSWORD}
    volumes:
      - secure_data:/var/lib/mysql
    networks:
      - nextcloud_network

  app:
    image: nextcloud:latest
    container_name: nextcloud_app
    ports:
      - 8080:80
    restart: always
    environment:
      - MYSQL_HOST=db
      - MYSQL_DATABASE=${MYSQL_DATABASE}
      - MYSQL_USER=${MYSQL_USER}
      - MYSQL_PASSWORD=${MYSQL_PASSWORD}
    depends_on:
      - db
    volumes:
      - nextcloud_data:/var/www/html
    networks:
      - nextcloud_network
      
volumes:
  secure_data:
    driver: local
    driver_opts:
      type: none
      device: /var/lib/docker-volumes/mariadb_secure_data
      o: bind
      
  nextcloud_data:
    driver: local
    driver_opts:

      device: /var/lib/docker-volumes/nextcloud_data
      o: bind

sudo nano .env

MYSQL_ROOT_PASSWORD=your_root_password
MYSQL_DATABASE=your_database
MYSQL_USER=your_user
MYSQL_PASSWORD=your_password

MYSQL_ROOT_PASSWORD=your_root_password
MYSQL_DATABASE=your_database
MYSQL_USER=your_user
MYSQL_PASSWORD=your_password

use the chmod command to restrict permissions for the file to that of the user that has made the file

sudo chmod 600 .env

Before we start up the project we are gooing to need to make some more folders so that we can set the permissions for them

sudo mkdir -p /var/lib/docker-volumes/mariadb_secure_data

sudo mkdir -p /var/lib/docker-volumes/nextcloud_data

Next we will set the permissions of the to folders that we have made with chmod but this time we are going to set them to 700 which means that the root account is the only one that can interact with the folders

sudo chmod 700 /var/lib/docker-volumes/mariadb_secure_data

sudo chmod -R 700 /var/lib/docker-volumes/nextcloud_data

last we are going to use chown to set ownership of a folder where nextcloud will store your data.

sudo chown -R www-data:www-data /var/lib/docker-volumes/nextcloud_data

With all of this done it is time to start this project up

sudo docker compose up -d
