led us to the Cloud Native Computing Foundation’s GitOps Working Group (and later the OpenGitOps project). By then, GitOps was a topic everyone wanted to know about. Suddenly, we were asked to spur discussions has fostered a whole new way of thinking about application deployment, because con- figuration files are used to declare the creation of container instances and dictate how the platform goes on to deploy and certification through standardized documents and code. OpenGitOps is currently a sandbox project within the CNCF. In October 2021, the GitOps Working Group released the OpenGitOps Principles [1

automation/scripting, declarative environment minimizes or eliminates this need ● Declarations are yaml files which are easily stored and managed in git OpenShift GitOps Principles ● Separate application source namespace: argocd spec: destination: namespace: argocd server: https://kubernetes.default.svc project: product-catalog source: path: manifests/app/overlays/dev-quay repoURL: https://github.co things in a specific order ○ Subscribe Operator before deploying instance ○ Create namespace/project before deploying application into it ○ Deploy required infrastructure before application (try to

CONFIGURATION DRIFT DETECTION A GitOps approach suggests that your declarative configuration files and application code should be stored together in the Git repository. This is what we call the and SRE teams are adopting GitOps so that you can store all your infrastructure configuration files as code. GitOps innately has Infrastructure as code as one of its characteristics. STRONGER below: HELM Helm is based on the parameterized templating approach where all resource definition files of applications are templated to make them customizable based on the requirement. Nowadays, it is

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 code com/microservices-demo/microservices-demo - This is the repo that stores the Kubernetes configuration files for the application. The Weave Cloud deployment agent automatically updates the front- end YAML manifest ssh URL with the path to the YAML files for the microservices-demo: SSH URL: git@github.com:/microservices-demo Path to YAML files: deploy/kubernetes/manifests

people to do commits to specific branches and include environment-specific code. ● It makes your project coupled to specific environments (instead of being generic). ● It requires extra effort to keep production as well? These kinds of questions are pretty important for most product owners and project managers and finding an answer should be as quick as possible. Currently, GitOps tools work mentioned already in ​Lack of Visibility​. Let’s say that you are using GitOps for a specific project and you know that the Git history matches your cluster history. How quickly can you answer the

internal platform is the key enabler. Weaveworks, one of the key organizations behind the OpenGitOps project, recently announced the release of Weave GitOps, a full-stack GitOps platform based on Weaveworks’ journey and you’d like to test the waters first, Weave GitOps Core is the underlying open source project that any organization can get started with. It includes many of the essential GitOps capabilities
