Docker and Kubernetes: Game-Changers in App Deployment

Enter Docker and Kubernetes, the dynamic duo that has revolutionized the way applications are deployed, managed and scaled. Here’s HOW!

In today’s rapidly evolving digital landscape, efficient and seamless application deployment is paramount for businesses seeking to stay ahead of the competition. Enter Docker and Kubernetes, the dynamic duo that has revolutionized the way applications are deployed, managed and scaled. Docker and Kubernetes have become game-changers in app deployment. This empowers organizations to streamline their development processes, enhances scalability and drives operational efficiency.

Here, we’ll delve into the world of Docker and Kubernetes, exploring their fundamental concepts, their interplay and their transformative impact on application deployment. We’ll uncover the key advantages they bring to the table, as well as real-world use cases where organizations have harnessed their power to achieve remarkable results. So, buckle up and get ready to embark on a journey where we unravel the game-changing potential of Docker and Kubernetes in app deployment.

Docker

Gone are the days of traditional monolithic applications and complex deployment procedures. Docker, an open-source containerization platform, enables developers to package applications and their dependencies into lightweight, portable containers. These containers encapsulate everything needed to run the application, from the code to system libraries, eliminating the “works on my machine” problem and ensuring consistency across different environments. Docker’s containerization brings unparalleled flexibility and reproducibility, allowing applications to run seamlessly across various operating systems and infrastructures.

Simplify Your Kubernetes Deployments with ArgoCD and GitOps 

In this blog, we’ll discuss how ArgoCD can help you simplify your Kubernetes deployments. ArgoCD is a Kubernetes tool that allows you to automate your deployment process and manage your applications using GitOps. This means that you can define the desired state of your Kubernetes resources as code, and ArgoCD will ensure that your cluster matches this state.


By the end of this blog, you’ll have a solid understanding of how to use ArgoCD to simplify your Kubernetes deployments and streamline your workflows.

GitHub: Self-Hosted Runner on Kubernetes

GitHub Actions is a powerful tool for automating software workflows, and it can be used to build, test, and deploy code right from GitHub. It provides a way to automate repetitive tasks and can be integrated with many popular tools and platforms.

GitHub Actions can use two types of runners: hosted and self-hosted.

  • Hosted runners are provided by GitHub and run on virtual machines in the cloud.
  • Self-hosted runners are machines that you set up and manage yourself. They run on your infrastructure, and you can customize them to meet your needs.

In this tutorial, we will show you how to set up GitHub’s self-hosted runner on Kubernetes.

Prerequisites

Before you begin, make sure you have the following:

  • A Kubernetes cluster
  • Helm Installed
  • Access to a GitHub repository for creating PAT and adding runners.

Cert-Manager Issuer for Cross-Account Route 53 [ EKS ]

Cert-Manager is a very powerful tool when we talk about managing TLS certificates & issuers and no other tool comes near the Cert-Manager for kubernetes in terms of open source, visibility, documentation, installation option, integration, and many more. Even with the same account or cross-account option, there is a direct integration option provided by cert-manager CRDs. This will lead to ease of setting of certificates and managing those created certificates.

ASSUMPTION

For this session/blog, we are going to use ACME certificates [or Let’s encrypt certificates] using DNS01 challenger.

Before setting up we need to have the clarity of account and their functionality.

ACCOUNT-X — EKS SETUP

ACCOUNT Y — ROUTE 53

NOTE: For the same account, you can use serviceaccount to make a call through OIDC To AWS IAM Role.
