HOW TO INSTALL Nextcloud through Docker and Portainer using Debian 11 / Ubuntu

Introduction

This tutorial will guide you through the process of installing Nextcloud using Docker and Portainer on Debian 11 or Ubuntu. Nextcloud is a powerful open-source tool for file sharing and collaboration, and using Docker simplifies the installation and management of applications. By the end of this guide, you will have a fully functional Nextcloud instance running on your server.

Step 1: Prepare the Server

Before installing Docker and Portainer, you'll need to set up a directory for Nextcloud and ensure your system is updated.

1. Create a directory for Nextcloud:

   sudo mkdir /nextcloud
   

2. Set the correct permissions:

   sudo chown www-data:www-data /nextcloud
   

3. Update your package list:

   sudo apt update
   

Step 2: Install Docker

Next, you need to install Docker, which will allow you to run applications in containers.

1. Install Docker:

   sudo apt install docker.io
   

2. Enable Docker to start on boot:

   sudo systemctl enable docker
   

3. Start the Docker service:

   sudo systemctl start docker
   

Step 3: Install Portainer

Portainer is a lightweight management UI that allows you to manage your Docker containers easily.

1. Run the Portainer container:

   sudo docker run -d -p 8000:8000 -p 9000:9000 -p 9443:9443 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest
   

   • This command does the following:
     • Runs Portainer in detached mode.
     • Maps necessary ports for accessing the Portainer UI.
     • Restarts the container automatically if it stops.

Step 4: Access Portainer

After installing Portainer, you can access its web interface to manage your Docker containers.

1. Open a web browser and go to:

   • http://<your-server-ip>:9000
   • Replace <your-server-ip> with your server's IP address.

2. Set up your Portainer admin account.

Step 5: Deploy Nextcloud using Portainer

Now that you have Portainer set up, you can deploy Nextcloud easily.

1. Log in to Portainer.

2. Create a new container for Nextcloud:

   • Click on "Containers" and then "Add container."
   • Set the container name (e.g., nextcloud).
   • Use the image nextcloud from Docker Hub.
   • Set the necessary ports (e.g., 8080:80).
   • Configure volumes for persistent storage.

3. Start the Nextcloud container.

Conclusion

You have successfully installed Nextcloud using Docker and Portainer on Debian 11 or Ubuntu. This setup allows for easy management and scalability of your Nextcloud instance.
