Docker Compose vs Dockerfile

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

Managing Multiple Clusters with ArgoCD

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

Argo CD : cluster disaster recovery

As organizations continue to adopt cloud-native technologies and embrace microservices architectures, managing and recovering from cluster disasters becomes increasingly important. In the event of a disaster, you need to quickly and easily recover your cluster without having to manually recreate every component. In this blog post, we'll explore how Argo CD can simplify the disaster recovery process and ensure that your cluster is up and running as quickly as possible. Argo CD is a popular GitOps tool that helps you automate your Kubernetes deployments. It helps you manage your entire cluster configuration as code and keeps your cluster in sync with your Git repository. One of the benefits of using Argo CD is that it makes cluster disaster recovery super easy. Let's say you have an EKS cluster in region 1a that completely crashes. With Argo CD, you can create a new cluster and point it to the same Git repository where the complete cluster

Laravel Eloquent groupBy() AND also return count of each group

It groups your data into separate collections, each containing all the rows with a matching value in the specified

Benefits of Using GitOps with ArgoCD

If you're involved in deploying applications on Kubernetes, you're probably already familiar with the challenges and complexities of managing your deployments. In this blog post, we'll explore some of the benefits of using GitOps with ArgoCD. GitOps is a way of managing infrastructure and applications on Kubernetes using Git as the single source of truth. GitOps applies the principles of Infrastructure as Code (IaC) to the entire application stack, from infrastructure to the application itself. By defining your infrastructure and application configuration in Git, you can version, review, and rollback changes just like you would with application code. ArgoCD is an open-source GitOps continuous delivery tool for Kubernetes. It provides a declarative way of managing your Kubernetes resources using Git as the source of truth. With ArgoCD, you can automate your application deployment and rollbacks, manage multiple environments and clusters, and monitor your deployments for changes and issues. One of the

How can I make Jenkins CI with Git trigger on pushes to master

In this Github Actions tutorial, we'll go through the following topics. First, I'm going to explain what Github actions actually is, and we're going to look at specific developer workflow use cases that you can automate with Github actions. After that, I will explain the basic concepts of Github actions, including the events and actions and workflow, and how Github actions actually automates these workflows using these components. Having understood what Github actions solves and how it makes it possible, I will go through the most common workflow, which is Cicd Pipeline. 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

Running MySQL Server in Docker Container and Connecting to it from Host Machine

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.

Building Microservices with Docker: Creating a Product Service

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
