strategically about how they would go about building and maintaining the platform. Further, how they would build a new development culture around the platform that makes software delivery seamless. In this paper serves to deliver an outstanding developer experience. Further, we look at how GitOps is the way to build internal platforms at scale. With these key strategic initiatives in place, software delivery teams productive and deliver applications more quickly. The tools and services that developers need to build and ship applications are what make up the developer experience (DX). Crafting a seamless DX is

it was clear that Christian had developed a strong starting point for organizations looking to build their own GitOps practices. I’m really excited to see those practices summarized for the masses very linear, basing each stage on previous ones. That’s why the term commonly used for the CI/CD build/test/deploy process is a pipeline. It can provide integration, delivery, and deployment in a continuous and can also add customizations on top of them. You can also write kustomization.yaml files that build on one another (for example, a base can refer to another base). Figure 3-1 shows a typical use

developer pushes the code to Git, a continuous integration tool kicks off unit tests that eventually build the Docker container image that gets pushed to the container registry. Figure 1 BROUGHT TO YOU the code is revised and re-approved, it is merged to Git. 4. The Git merge triggers the CI and build pipeline, runs a series of tests, and then eventually builds a new image and deposits the new repository, providing your team with a secure method for creating updates.

handled by different systems. In order to create a correlation between them, developers often have to build additional cruft on top of the deployment platform and ever resort to custom low-level scripts that categories: 1. Really low-level tools that are mostly useful to developers. They are full of build logs, Git hashes, and deployments events that mean nothing to product owners or business analysts
