Containerization Concepts

Containerization allows applications to packaged with their dependencies into standardized units called containers.


  • Portability between environments
  • Ensure consistency
  • Streamline deployment

Docker is a popular containerization platform. Key concepts:

  • Images: Blueprint describing the environment
  • Containers: Running instances of images
  • Dockerfile: Defines how to build an image

With Docker we can package applications into images that can be run reliably as containers anywhere.

Docker Setup

To build a Docker image for a Node.js app:

  1. Create a Dockerfile
  2. Define base image, copy source code, specify commands
  3. Build image: docker build
  4. Run container from image: docker run

Deploying Containers

Platforms like make it easy to deploy Docker containers.

To deploy on

  1. Install flyctl CLI
  2. Sign up and login
  3. Launch app with flyctl launch
  4. Deploy updates with flyctl deploy handles running containers on their infrastructure.

Even Further Beyond

Some further technologies:

  • Redux, SWR, Axios
  • GraphQL
  • Nest.js
  • Deno
