What is Docker?

Docker, a new container technology that allows you to package an application with all of its dependencies into a standardized unit for software development. Docker containers wrap up a piece of software in a complete filesystem that contains everything it needs to run: code, runtime, system tools, system libraries – anything you can install on a server. This guarantees that it will always run the same, regardless of the environment it is running in.



Docker is a tool that is designed to benefit both developers and system administrators, making it a part of many DevOps (developers + operations) toolchains.

How it works?

  • Docker has two major components:
    – Docker: the open source container virtualization platform.
    – Docker Hub: Software-as-a-Service platform for sharing and managing Docker containers.
  • Docker uses a client-server architecture.
  • The Docker client talks to the Docker daemon, which does building, running, and distributing the Docker containers.
  • Both the Docker client and the daemon can run on the same system, or we can connect a Docker client to a remote Docker daemon.
  • The Docker client and daemon communicate via sockets or through a RESTful API.
  • We can build Docker images that hold our applications.
  • We can create Docker containers from those Docker images to run our applications.
  • We can share those Docker images via Docker Hub or our own registry.
