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

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.

How to Set up Docker Registry and a Docker RegUI

In this story, we will install Docker Registry on a VM and the cloud and we will add a Docker container to browser the registries from a web browser. From my side, I created an ECS instance on Alibaba Cloud. But we could do it everywhere. After creating the ECS instance, I got its public IP address (8.208.91.39) and I created a security group to authorize the following ports:

  • 5000 for the Docker Registry,
  • 8086 for the Docker Registry UI.

#docker #devops #docker-compose #docker-registry

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.

In this guide, I have explained the Top 24 Docker Commands with examples.

Make sure you have sudo or root privileges to the system.

Docker Commands

  1. The command to check the version of Docker installed.
  2. To look/search for available docker images from the Docker registry.
  3. To pull docker images from the Docker registry.
  4. Listing all the docker images
  5. Creating / Running docker container from Docker image.
  6. To list the actively running docker containers.
  7. To list all the docker containers
  8. To stop a Container
  9. To start a Container
  10. To restart a Docker container
  11. To login to running Docker container
  12. To delete the stopped Docker containers
  13. To delete Docker images from the Local system
  14. To check logs of a running Docker container
  15. Killing docker containers
  16. Log in to Docker Hub registry (hub.docker.com)
  17. Removing docker hub registry login from the system.
  18. Check active resource usage by each containers
  19. Rename a Docker container
  20. To display system wide information of Docker
  21. Inspecting a Docker container
  22. Building docker images from Docker file
  23. Creating new docker images from a Container
  24. Pushing Docker images from Local to Docker registry.
