What are the differences between PM2 and Docker Compose?

What are the differences between PM2 and Docker Compose?

PM2 is a process manager for Node.js applications, while Docker Compose is a tool for defining and running multi-container Docker applications. PM2 focuses on managing application processes, whereas Docker Compose manages the deployment of applications in containers.

When should I use PM2 instead of Docker Compose?

Use PM2 when you need to manage Node.js applications directly, especially for features like clustering and monitoring. Use Docker Compose when you want to manage multiple services that may include databases, caches, and other components in a containerized environment.

Can I use both PM2 and Docker Compose together?

Yes, you can use both together. You can run your Node.js application in a Docker container managed by Docker Compose and use PM2 inside that container to manage the application processes.

What are the advantages of using Docker Compose?

Docker Compose simplifies the management of multi-container applications, allowing you to define services, networks, and volumes in a single YAML file. It also makes it easy to scale services and manage dependencies.
