Installation:

The installation of docker and nextcloud will be set up only on the private network, not publicly accessible for the time being. More than likely this tutorial will be updated over time with a comprehensive view. There will be screenshot to show what will transpire after the commands are typed in. Also, for simplicity you can copy and paste the commands the docker compose file in order to simple the process. Nextcloud can rather be difficult to install and setup so hopefully this tutorial will be comprehensive enough to install it on the Fedora server.

1. Open the terminal and type in the command:

sudo dnf install -y docker docker-compose

The "-y" flagging means yes to downloading of the required packages and necessary dependencies. You will be prompted to type in your password and followed by pressing enter. The download and installation process will commence.


2. After docker is installed it maybe required to active system daemon by typing in the command:
sudo systemctl start docker && sudo systemctl status docker

You will be prompted to type in your password followed by pressing the enter button on the keyboard.

In the screenshot above, we are looking to see if the system daemon is active which is in a green font color. Press "ctrl + C" to exit.


3. There are some basic commands that will be unearthed next coming steps to help with running docker. Personally, docker compose it much better to use because it is reusable and it is a file instead of a command. Organization of the system is paramount and it is sufficient to think methodically and organizing everything. We will create a directory with its corresponding directories by typing in the command:
mkdir –p ~/Docker/Nextcloud && cd ~/Docker/Nextcloud

This command will create the the parent directory with child directories and will change directory into the ~/Docker/Nextcloud. The "-p" flagging represent the parent directory as in it will create the pathway provided.


4. Now being within the current directory. A file will be created which will be titled "docker-compose.yml"; this is the standard name convention and cannot be customized, but the docker compose file must be unique to it’s own directory. Type in the command:
sudo nano docker-compose.yml

Now using nano text editor within the terminal will be opened up.


5. Copy and paste the code below and edit it as necessary in the terminal. The images will be used from the Linux server which do an excellent job of simplifying the installation process of Nextcloud. Configure the code below as needed

        
---
services:
  nextcloud:
    image: lscr.io/linuxserver/nextcloud:latest
    container_name: nextcloud
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
      - MYSQL_PASSWORD=Set_this_password!! #change this password for the sql 
      database
      - MYSQL_DATABASE=nextcloud
      - MYSQL_USER=nextcloud
      - MYSQL_HOST=db
    links:
      - mariadb
    volumes:
      - ~/Docker/Nextcloud/config:/config #change the pathway of the directory 
      if necessary
      - ~/Docker/Nextcloud/data:/data #change the pathway of the directory 
      if necessary
    ports:
      - 443:443 # change the internal to something else. The internal port is 
      the 443 for the container
    restart: always
  
  mariadb:
      image: linuxserver/mariadb
      container_name: mariadb2
      environment:
        - PUID=1000
        - PGID=1000
        - MYSQL_ROOT_PASSWORD=Set_this_Password!! #change this password for the 
        root password of the maria database
        - TZ=America/”New York” #set the timezone to your timezone
        - MYSQL_PASSWORD=Set_this_password!! #this password should be the same 
        as the above in the nextcloud instance
        - MYSQL_DATABASE=nextcloud
        - MYSQL_USER=nextcloud
      volumes:
        - ~/Docker/Nextcloud/mariadb:/config #change the pathway if necessary
      ports:
        - 3306:3306 #leave this port alone unless it interferes with another container.
      restart: always
              
          



After copy and pasting, the code. Press "ctrl + x" to exit the file then press "Y" meaning yes to save the file and press enter to keep the file name the same and will be closed out.

6. Next, to confirm the file saved, type in the command below:
cat docker-compose.yml
7. We will need to create the directories in the ~/Docker/Nextcloud for the docker compose to work properly. Type in the command while being in ~/Docker/Nextcloud
mkdir mariadb config data

Pressing enter after the command is typed in shows no feedback means the command was successfully executed.

8. Now we can run the file in order to install the docker container.
sudo docker compose up -d

The "-d" flagging will hide the all of the background installation and will present a clean screen install. If prompted to type in the password do so and press the "enter" button on the keyboard.



9. Type in the command below to confirm the Nextcloud and maria database are up and running.
sudo docker ps
10. We need to locate the private IP address associated the the computer device so type in the command:
ip addr show

The command will show all of the internet connection and convey which ones are active. Depending on how you are trafficking the internet you will see either “enp” state is “UP” which means the ethernet is connected to the server and this will provide the local ipv4 or inet which is the private network IP address that will be used to navigate to the nextcloud instance. If the device is connected through wifi you should see wlp state is "UP" which means the device is connected to the wifi. Either way you are wanting to retrieve the inet which is the IPV4 address which usually begins with 192.168.000.000. For security reasons, no photo will be provided for this step due to security reasons.

11. Now open up your web browser and type into the address bar:
https://192.168.000.000:443

Replace the URL with you private IPV4 address followed by the port.



This screenshot above is what it should look like for the first time navigation on the private network. However, you will need to submit your information and create an user. This tutorial will be amended over time to show a more in depth view to have the Nextcloud be accessible on the public network which will include Nginx proxy manager and portainer for container management.
