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.
