Deploying multiple applications on a single VPS using Docker allows for efficient isolation and management of each app in containers. By installing Docker and creating a docker-compose.yml file, you can easily launch and manage services like Node.js and PHP. Additionally, tools like Portainer provide a user-friendly web interface for streamlined container management, making updates and oversight simpler.


Deploying Multiple Apps on a Single VPS with Docker

Docker enables efficient deployment of multiple applications on a single VPS by isolating them in containers. This simplifies management and updates.

Step 1: Install Docker

Install Docker on your server. For Ubuntu, use the following commands:

sudo apt update
sudo apt install docker.io

Start Docker:

sudo systemctl start docker
sudo systemctl enable docker

Step 2: Using Docker Compose

Create a docker-compose.yml file to manage your containers. Here’s an example with two apps (Node.js and PHP):

version: '3'
services:
  node-app:
    image: node:14
    ports:
      - "3000:3000"
  php-app:
    image: php:7.4-apache
    ports:
      - "8080:80"

Launch the services:

docker-compose up -d

Step 3: Manage via Portainer

To simplify container management, use Portainer, a web-based UI for managing Docker containers. To install it:

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

Once installed, Portainer will be available on port 9000.

Conclusion

Using Docker and tools like Portainer allows you to deploy and manage multiple applications on a single VPS easily, simplifying service management and updates.
