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

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

Any changes to the git repository What is GitOps? 3 Why GitOps?

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

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

configuration is guaranteed by a set of facts instead of by a set of instructions. With your application’s declarations versioned in Git, you have a single source of truth. Your apps can then be easily driven. This trivializes rollbacks; where you can use a `Git revert` to go back to your previous application state. With Git’s excellent security guarantees, you can also use your SSH key to sign commits microservice repo and in that repo, you bundle your application code along with deployment YAML manifest files or a Helm chart that define how your application will run in your cluster. When you push that

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

realize. Created for a cloud-native world, GitOps makes developers more productive while improving application stability, security and compliance – and it does all this without the need for developers to learn from the application code itself to the underlying infrastructure and configuration – you can keep it in version control. This means the desired state and any changes of an entire application stack from code. It is this declarative nature that enables the infrastructure to be held in Git alongside application code. This built-in observability allows for fast iteration and experimentation, and allows development

characteristics and selling points, the current GitOps tools focus only on the deployment part of an application and nothing else. They solve the “I want to put in my cluster what is described in Git” problem code. But in most cases, in order to run unit tests, you need access to the source code of the application. The current crop of GitOps tools cannot run unit/integration tests. That would require visibility environments per geographical region (per continent or per country). Let’s say that my application is deployed to 10 countries and I want to promote a release to one after the other. What is the
