Docker Overview

Docker is an operating-system-level virtualization technology used to run software packages called containers. Containers are created from images that specify their precise contents, often built by combining and modifying standard images downloaded from public repositories. Unlike virtual machines, all containers run by a single operating system kernel, making them more lightweight and efficient.

Key Features​

  • Lightweight: Containers share the host system's kernel, making them more lightweight than virtual machines.
  • Portability: Containers can run consistently across various environments, from development to production.
  • Isolation: Provides process and resource isolation for applications.
  • Efficiency: Faster startup times and reduced overhead compared to traditional VMs.
  • Scalability: Easily scalable to manage complex applications and services.

Getting Started with Docker​

  1. Running Containers: Use Docker commands to run and manage containers. 
    sudo docker run -d -p 80:80 nginx
  2. Using docker-machine: Create and manage Docker hosts using the docker-machine CLI. 
    docker-machine create --driver virtualbox my-docker-host
  3. Building Images: Build Docker images from a Dockerfile. 
    docker build -t my-image .
  4. Pushing to Repositories: Push Docker images to a repository. 
    docker tag my-image my-repo/my-image
    docker push my-repo/my-image
