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 on0 码力 | 8 页 | 1.35 MB | 1 年前3The Path to GitOps
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 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 the entire software infrastructure at a datacenter using configuration files that are both ma- chine-readable and human-readable. The configuration files are machine-readable in a structured format (usually0 码力 | 45 页 | 1.09 MB | 1 年前3Getting Started and Beyond: Istio Multicluster with GitOps

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 Git as the single source of truth, and all platform configuration stored in Git, platform operations can be automated with ease.

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 make crucial decisions before they deploy new features. Features or other updates like cluster configuration can be pushed to Git and then observed in real-time – and rolled back if necessary.

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 release to a previous environment (e.g. production to QA in order to examine a bug) ● has a configuration mechanism in place to define multiple version of the same environment (i.e. for different geographical0 码力 | 29 页 | 1.61 MB | 1 年前3From DevOps to GitOps with GitLab 公開版

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 resource allocations to meet the user demands. But, what happens if the deployment fails, or a configuration error causes a networking issue?
