A GitOps continuous delivery tool for Kubernetes
Nothing but the Truth
GitOps is a paradigm or a set of practices that empowers developers to perform tasks that typically are done by the operations team. GitOps requires code to be declarative and uses Git as the single source of truth for the system's desired state. The Git repository, in this case, becomes the core element for version control, code review, and automated deployment.
Argo CD, a project of the Cloud Native Computing Foundation (CNCF), is a declarative, GitOps continuous delivery tool for Kubernetes. It leverages the Git repository as the source of truth for Kubernetes resources and applications' desired state.
GitOps is a way of implementing continuous deployment (CD) for cloud-native applications. It focuses on a developer-centric experience when operating infrastructure with the use of tools with which developers are already familiar, including Git and continuous deployment tools.
The "Ops" in GitOps does not mean that developers become responsible for operations. It means that operational procedures are encoded in software and become part of the codebase. For some reason or another, today's GitOps are most often associated with Kubernetes, but in principle, it can be used in conjunction with any other environment.
Why Argo CD?
Argo CD is designed to solve the complexities around Kubernetes deployment. It follows the GitOps pattern of using Git repositories as the source of truth for defining the desired application state. Kubernetes manifests can be specified in several ways, such as Kustomize applications, Helm charts, Jsonnet files, plain YAML and JSON manifest directories, and any custom management tool configured as a config management plugin. As a GitOps tool, Argo CD brings several benefits to the table. It allows for easy tracking of all changes, automatic application deployments, and quick rollbacks if necessary. It also ensures consistency and stability of
