requires tools that developers know and understand. GitOps is our name for how we use developer tooling to drive operations. GitOps is a way to do Continuous Delivery. More specifically, it is an operating approach, your CI tooling pushes and deploys images to the cluster.

approach, your CI tooling pushes and deploys images to the cluster. For the CI system to apply the changes to a cluster, you have to share your API credentials with the CI tooling. That means your CI you're using GitOps. GITOPS DEPLOYMENT WORKFLOW OVERVIEW The GitOps core machinery is in its CI/CD tooling, with the critical piece being continuous deployment (CD) that supports Git-cluster synchronization cluster, CI and CD tooling, and the container repository, providing your team with a secure method for creating updates.

application code, and configs. Updates to the application repo trigger processes with your CI/CD tooling to update the config repo. The config changes are then pushed/pulled to the deployment environment as Code (IaC) One very common practice teams adopt for their GitOps strategy is implementing IaC tooling and best practices. The process involves managing and provisioning infrastructure resources using files, allowing for rapid, repeatable, and error-free provisioning of infrastructure. Popular tooling to support IaC includes Terraform, Pulumi, Ansible, Salt, and Puppet. These tools provide the necessary

the solution to those issues and what we expect from GitOps 2.0 – the next generation of GitOps tooling. Visibility into the whole software lifecycle The current generation of GitOps tools focuses environments should be considered an integral part of any deployment solution. In the case of GitOps tooling, we can handle the promotion mechanism in a different number of ways, such as introducing an automation

requests drive all application & infrastructure changes ● Cluster state always matches Git state ○ Tooling should understand and monitor for configuration drift ● Deployments & rollbacks should be painless

Kubernetes and is certified Kubernetes conformant meaning it leverages all the benefits of open source tooling from the community and enables migration from standard Kubernetes applications without code refactoring

already been leveraging Git for collaboration, have a CI/CD pipeline in place, and use open source tooling across your pipeline, you may see quicker adoption time. However, for many organizations, it can
