of Ops. GitOps is rapidly gaining popularity to extend the scope of DevOps further to include application infrastructure. In this article, we will have a look at GitOps and how to leverage it for delivering GitOps is a set of practices that are aimed at managing the underlying infrastructure of an application. It utilizes Git as the source code management tool for managing the infrastructure code. In other management, which both: Increases the overall visibility Reduces the management overhead of the application infrastructure GitOps allows developers or the Ops team to declare their infrastructure as code

Reflecting an Organizational Boundary Kubernetes Platform Administrator Kubernetes Application Developer Other Boundaries GitOps Repo Example Conclusion 33 Chapter 6–CI/CD likely be presented with a lot of familiar concepts that seem unrelated. Is GitOps something that application developers use? Is it for infra- structure folks or system administrators? Is it something you (CI/CD) [1.2]? As a matter of fact, GitOps unifies a collection of different topics in automation, application delivery, infrastructure management, and security. In this chapter, I will go through each aspect

Stream-aligned teams are essentially application development teams that build features and release code into production. Platform teams, on the other hand, exist to support application development teams and make make resources available to them whenever needed. Application development teams Application development teams deliver applications and products to end-users. These teams are aligned according to the organization’s organize their development teams by-product, although in some cases it can be by department. Application development teams care about moving faster and deploying new features and updates with little

over a decade, software companies have been trying to move away from the waterfall approach to application development to the DevOps approach. Instead of throwing code over a wall to a separate engineering the complexity of the steps previously handled by large teams must be adopted. The monolithic application should be split up into microservices that can each be owned by a single team. Organizational changes and updates very quickly in response to users’ feedback without taking down the whole application and improves development metrics by orders of magnitude in some cases. However, developers using

GitOps and how it solves both technology and organizational problems around CI/CD, Kubernetes application drift, and traceability through the engineering process. New: GitOps Continuous Delivery with ● Git as a system of record for the desired state of configuration ● Pull requests drive all application & infrastructure changes ● Cluster state always matches Git state ○ Tooling should understand Ready: SSO, multi-cluster, and audit trails ● Extensibility: Rich CLI, webhooks, events, and polished web UI @codefresh Argo CD A declarative GitOps continuous delivery tool for Kubernetes https://argoproj

the application. Ideally, the developer focuses mainly on delivering business value via code. Thus, to improve developer experience, GitOps emerged where infrastructure and application configuration ecosystem. The focus is entirely on keeping Git as a single source of truth for infrastructure and application configuration changes. In an ideal world, this approach allows the developer to focus on working 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 deploy both application and infrastructure

Solutions Architect https://github.com/pixeljonas 2 GitOps is when the infrastructure and/or application state is fully represented by the contents of a git repository. Any changes to the git repository What is GitOps? 3 Why GitOps? It takes weeks (or months!) to provision an environment The application behaves different in production than it did in test Environments are all manually configured A Smarter Kubernetes Platform Automated, full-stack installation from the container host to application services Seamless Kubernetes deployment to any cloud or on-premises environment Autoscaling

differences between GitOps and DevOps, and how to ensure Git is the single source of truth for your application in our free Understanding GitOps guide. DOWNLOAD NOW | 05 3 KEY ELEMENTS FOR YOUR GITOPS implementation of DevOps that uses Git as the single source of truth for declarative infrastructure and application code. In GitOps, the desired state of the system is versioned and stored in a Git repository, automates application code deployments and infrastructure management. Adhere to best practices by creating separate repos for your application code, and configs. Updates to the application repo trigger
