Specifically, continuous integration (CI) and continuous delivery (CD) tooling. My mindset at the time was, “We can do better.” We something you can buy off the shelf? Or is it just a fancy new term for DevOps [1.1], or continuous integration/continuous deployment (CI/CD) [1.2]? As a matter of fact, GitOps unifies a collection of different

Running GitOps at scale 2.7 deployments 3.2. Deployment value comes from features and not Git hashes 3.3. The new Codefresh GitOps dashboard 3.4. Argo CD Integration 3.5. CI/CD pipelines with Codefresh 3.6. Getting started with GitOps 2.0 Introduction GitOps is the practice of deploying applications by using Git Operations only (and not clicking UI buttons). The paradigm already existed in one form or another

by using Git as a source of truth for declarative infrastructure and applications. Automated CI/CD pipelines roll out changes to your infrastructure when commits are pushed and approved in Git. It also pieces together. Whatever you choose for your delivery pipeline, applying GitOps best practices with Git (or any version control) should be an integral component of your process. It will make building and 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 deployed and rolled back to and
