In my previous blog https://www.leogether.com/2020/09/creating-kubernetes-cluster-with-azure.html
I created the Azure Container Registry and Kubernetes cluster using Terraform and Azure DevOps. I would encourage you to read my previous blog first before reading this.
In this blog, I will show you how to import a docker image into the Azure Container registry and deploy the application in the Kubernetes cluster using the Azure DevOps YAML pipeline. The complete architectural flow is as below:
Hi Everyone, in this blog we will see how to deploy the multi-container applications using Docker Compose.
Docker Compose is a tool for running multi-container docker applications. Usually, one container is used to host one service. Let's take a case where have a massive application where you have multiple services, in that case, we would need several containers for each service and containers will need to interact with each other. Creating it manually using the docker run command will be complicated.
I talked about dockers and containers in one of my blogs:

Now let's talk about what is Kubernetes and why do we need it?.
Containers are fast, reliable, light-weighted, and scalable.
You can easily scale 1 container to many containers but in the real world, there is a need that large organizations will scale multiple containers for an application, needed to ensure availability, load balancing, scaling up, and down based on the load. In such a situation you will need to manage containers like deploying, scheduling, scaling up and down, load balancing, monitoring in some automated way. For this reason, we need a container management tool.
Kubernetes is an opensource container orchestration tool/engine to automate deployment, scale, and manage the containerized application on a group of servers.
Docker is a containerization platform, and Kubernetes is a container management platform.
An application works in the Dev environment but the same fails in testing or prod environment due to different computing environments.
Docker is a container-based technology to create, deploy, and run applications by using containers.
They are lightweight alternatives to VMs, uses host OS, and do not need to pre-allocate any RAM.
Below are self-explanatory diagrams of what is docker and how docker works.
Welcome visitor! Thank you for stopping by. This is the first blog of mine and I hope you like it. I am really excited about it. Please bear with me and I promise to get better every time.
In this article, you are going to see a complete tutorial on how can we can containerize a .net microservice. I will go step by step so that you can follow along. The following steps are covered:
