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 teams can release software continuously, and with full confidence in the reliability of the system.

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 unrelated. Is GitOps something that application developers use? Is it for infra- structure folks or system administrators? Is it something you can buy off the shelf? Or is it just a fancy new term for DevOps change took down their entire hosting platform, but the DevOps engineers were able to bring back the system in about 40 minutes. When asked how they did it so quickly, they described their process, which

GitOps is significantly speed up your team’s ability to ship features. eBook 4 The Principles of GitOps The entire system is described declaratively. Kubernetes is just one example of many modern cloud native tools that reproduced. --------------- --- The canonical desired system state is versioned in Git. With the declaration of your system stored in a version control system, and serving as your canonical source of truth

• GitOps for Kubernetes Essentials • Conclusion Git is the most widely used version control system, with more than 80 percent of its market share in today’s software industry. GitOps is a methodology infrastructure definitions can be kept alongside application code in Git. Keeping your entire system in Git means that your development team uses familiar Git-based workflows and pull requests to (VCS) like Git should be the only source of truth. Whatever changes one wants to perform in the system should be declared and always committed first in Git or the GitLab repo alone. This helps to identify

what is described in Git (the desired state) with what is currently running in the clusters. Build Deploy “Immutability Firewall” Test Operate & Manage IDE Monitor GIT GitOps unifies deployment code. The system’s entire infrastructure must be described in Git. After a PR is merged, the changes are automatically applied using tools like Weave Kubernetes Platform. Once the system is described require cluster credentials or manual intervention to make a change to the system. As a segregated environment, the system can only be changed through Git, thereby reducing user error and speeding

straight-forward: ● Infrastructure as Code: Git is always the source of truth on what happens in the system ● Code changes always go through an automated process ● Deployments, tests, and rollbacks controlled at any moment. Those continuously compare the current state with the desired state to ensure the system is running like expected. The most popular GitOps tools today are ​Flux ​and ​ArgoCD​. As several GitOps has been heralded as a way to decouple CI from deployments. In the classic use of a CI/CD system, the last step in the pipeline is a deployment step. Classic pipeline With GitOps you

truth for declarative infrastructure and application code. In GitOps, the desired state of the system is versioned and stored in a Git repository, and a reconciliation loop continuously monitors and published by the GitOps Working Group: The desired state of a GitOps managed system must be: 1. Declarative A system managed by GitOps must have its desired state expressed declaratively the source. 4. Continuously reconciled Software agents continuously observe the actual system state and attempt to apply the desired state. The Philosophy of GitOps | 07 3 KEY ELEMENTS

apply when implementing and dealing with GitOps. Let’s take a look. Declarative system In the GitOps model, the complete system is configured declaratively. This declarative approach is focused on the result facilitating convenient deployments and rollbacks. The system state is versioned in Git All the declarative states are stored in the version-controlled system, which acts as the single source of truth. With With this version-controlled approach, all the system infrastructure changes are available chronologically, enabling users to identify infrastructure changes over time easily. It is also helpful in: Troubleshooting
