Docker Architecture Overview & Docker Components [For Beginners]

If you have recently come across the world of containers, it’s probably not a bad idea to understand the underlying elements that work together to offer containerisation benefits. But before that, there’s a question that you may ask. What problem do containers solve?

After building an application in a typical development lifecycle, the developer sends it to the tester for testing purposes. However, since the development and testing environments are different, the code fails to work.

Now, predominantly, there are two solutions to this – either you use a Virtual Machine or a containerised environment such as Docker. In the good old times, organisations used to deploy VMs for running multiple applications.

So, why did they started adopting containerisation over VMs? In this article, we will provide detailed explanations of all such questions.

Docker Explained: Docker Architecture | Docker Registries

Following the second video about Docker basics, in this video, I explain Docker architecture and explain the different building blocks of the docker engine; docker client, API, Docker Daemon. I also explain what a docker registry is and I finish the video with a demo explaining and illustrating how to use Docker hub

In this video lesson you will learn:

  • What is Docker Host
  • What is Docker Engine
  • Learn about Docker Architecture
  • Learn about Docker client and Docker Daemon
  • Docker Hub and Registries
  • Simple demo to understand using images from registries

#docker #docker hub #docker host #docker engine #docker architecture #api

Introduction to Docker: What is, Architecture, Workflow

History of Virtualization

Not so long ago from now, deploying a service was a process that was both slow and painful. The process involved the writing of code by the development team and then its deployment by the operations team on metal machines. The operations team used to have their work cut out as they had to look for language compilers, libraries, and patches to make the code work.

If the process had any errors or bugs, it would have to start all over again – the development team would fix the bugs or errors, and the operations team would again begin deploying the code.

Things got a little better when Hypervisors were developed. So, what are Hypervisors? These are a collection of virtual machines (VMs) that may be continuously be running or switched off at regular intervals, especially when not in use. Virtual machines definitely helped by accelerating the process of the fixing of errors and the deployment of code, but they still had a few issues. Docker containers came as the real game-changers. They even addressed the issues that existed in virtual machines.

What is Docker Container? Function, Components, Benefits & Evolution

Docker‘ is a Platform set as a Service (PaaS) product intended to deliver software in the form of packages, which are termed as containers. It uses OS-level virtualization standards, wherein the kernel allows multiple instances of isolated user-space such as containers, partitions, zones, virtual kernels, etc.

These behave as real computers simulating the way programs are run in them. On a regular operating system, we see the resources the computer program is running. In containers, we can only see the contents and the devices allocated to the container when the programs are run in it.

For several developers in the industry today, Docker is the accepted standard for developing and sharing containerized apps, across the desktop and the cloud. Containers are a standardized unit of software. Developers use it to isolate an app from its environment. Due to their lightweight characteristics, several docker containers (typically above eight containers per host) can be run on a single server or VM, simultaneously.
