Docker is a popular open-source containerization platform that enables developers to package applications into isolated containers for easy deployment and management. Docker Compose and Dockerfile are two of the most important components of the Docker platform. Docker Compose is a tool for defining and running multi-container Docker applications, while Dockerfile is a text document that contains all the commands a user could call on the command line to assemble an image. In this article, we will discuss the differences between Docker Compose and Dockerfile, their advantages and disadvantages, and how they can be used together. Docker Compose is a tool for defining and running multi-container Docker applications. It allows developers to define a set of containers, their configuration, and how they should be linked together in a single file. This file can then be used to create and run the application with a single command. Docker Compose is a great tool for quickly setting up and running

ArgoCD is a popular continuous delivery tool for Kubernetes, allowing users to deploy and manage their applications in a Kubernetes environment with ease. However, as organizations scale and start to work with multiple clusters, managing ArgoCD configuration can become more complicated. In this blog post, we will discuss how to work with multiple clusters using ArgoCD. When working with multiple clusters, one approach is to deploy ArgoCD in each cluster separately. This way, each ArgoCD instance can manage the resources of its own cluster, and changes can be tested and rolled out independently in each environment. However, this approach can result in managing multiple ArgoCD instances, which can be time-consuming and require additional maintenance. Another approach is to deploy ArgoCD in one cluster and configure it to deploy changes to multiple clusters at the same time. This way, Kubernetes administrators can configure and manage one ArgoCD instance, which can configure a fleet of clusters. This
As organizations continue to adopt cloud-native technologies and embrace microservices architectures, managing and recovering from cluster disasters becomes increasingly important.

I will explain shortly why it's not just another Ci Cd tool, or what are the benefits of Github actions Cicd Pipeline. Finally, we will go through a hands-on demo where I explain the syntax of Github Actions workflow file, and then we will go through a complete Ci Pipeline setup with my example Java Gradle project which we will build into a docker image and
How do I access container port?
I am the happy administrator of an nginx docker container running in front of an application using a mysql database. The database runs on the host of the docker container and the container is not bound to the IP address of the machine. The challenge today is to connect to the mysql database from the docker container.
In the first video, we learned that an image is a template for the environment that you want to run, and when you run an image, you get a container. We tried this out by running a PHP image. This was okay for our very simple application, but imagine, if you have something more complicated, let's work through an example. Traditionally, a big website like an online store would be one big application, but a newer trend is to split these big applications up into smaller micro-services The website can then be quite minimal and it just makes calls to other services to get information or to ask them to do some piece of work. We're going to build a really simple ecommerce website, but we're going to put the codes that provides the product and the product information in its own microservice. The website will then use an api on the product service to request the list of
