as the infrastructure layer managing the applications. One day there was an incident where a configuration change took down their entire hosting platform, but the DevOps engineers were able to bring back process, which Weaveworks CEO and cofounder Alexis Richardson called “GitOps.” The DevOps engineers over at Weaveworks came up with a system that allowed them to return their entire platform (not just the infrastructure stack instead of just one object. We’ve seen that the desired state is pulled from configuration information that is versioned and stored in an immutable storage system. If there is a difference

Ecosystems NINAD DESAI STAFF ENGINEER, INFRACLOUD CONTENTS • About GitOps for Kubernetes • Configuration Management in Kubernetes • GitOps for Kubernetes Essentials • Conclusion Git is the most experience. In the last few years, the number of tools and systems needed to manage version control, configuration management, Infrastructure as Code, CI/CD, and observability have drastically increased. This Thus, to improve developer experience, GitOps emerged where infrastructure and application configuration changes revolve around Git, i.e., the version control ecosystem. The focus is entirely on

platform team had to start ordering additional servers two to three months in advance, and always over provision. Very short internal deadlines for big product launches, sometimes 30 minutes or less, entire software stack through Git and treat your servers as your source code. Every change and configuration is done through a pull request and everyone has access to the application, which can be rolled you should trust the platform you are building on. With GitOps, you can make sure that each configuration change is verified by your peers and automatically tested before it is deployed. Your platform

native tools that are “declarative” and that can be treated as code. Declarative means that configuration is guaranteed by a set of facts instead of by a set of instructions. With your application’s tool becomes a high value target. If someone breaks into your CI tool, they will have total control over your production cluster, even if your production cluster is highly secure. But what happens if continuous integration environment Runs inside the production cluster Read/Write access to configuration repository Read access to image repository Read/Write access to the production cluster GitOps

and GitOps For over a decade, software companies have been trying to move away from the waterfall approach to application development to the DevOps approach. Instead of throwing code over a wall to a separate entirely on GitOps best practices, reducing complexity of configuration management for complete Kubernetes platforms. By keeping the configuration in Git, developers and operators can use WKP to easily

the largest and longest-running project of its kind, pulling together six years of data drawn from over 31,000 technology professionals worldwide. It charts the performance of engineering teams across treat everything as code – 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 ecosystem of cloud native tools are declarative, as opposed to imperative, which allows for configuration to be treated as code. It is this declarative nature that enables the infrastructure to be held

infrastructure changes are available chronologically, enabling users to identify infrastructure changes over time easily. It is also helpful in: Troubleshooting Auditing Rollbacks Changes are automatically deployments. Increased productivity The source-controlled, validated infrastructure reduces configuration errors that can occur during deployments, saving time for Ops teams to diagnose and fix those pipeline and initializes the git operator. Then the git operator will compare the states. This new configuration will identify this as a state change and automatically orchestrate the underlying infrastructure

other solutions before it, has also several shortcomings. It seems that the honeymoon period is now over, and we can finally talk about the issues of GitOps (and the current generation of GitOps tools) being generic). ● It requires extra effort to keep all branches in sync (in case of hotfixes or configuration changes). ● It puts unnecessary strain on the CI system that has to check/rebuild/unit test each environment and can quickly lead to configuration duplication or people making commits to specific environments (instead of using shared configuration). For example, if you have 20 git repositories

architecture requires a GitOps operator, or agent, to evaluate both the infrastructure and application configuration in the repository to detect when the Kubernetes cluster resources should automatically update processes or interactive configuration tools. Ultimately this means codifying your workload by defining every application and infrastructure resource as declarative configuration files, allowing for rapid deployment of both application and infrastructure components while ensuring clear separation and control over changes in each layer of the system.
