Skyhook is a Kubernetes-aware package manager designed for cluster administrators to safely modify and maintain underlying hosts declaratively at scale. It functions like a package manager but for your entire Kubernetes cluster, with three main components: Skyhook Operator, Skyhook Custom Resource (SCR), and Packages. Skyhook is particularly useful in scenarios where updating hosts without re-imaging is necessary, managing OS image overlays, and handling workload sensitivity.

Features

• Skyhook Operator: Manages installing, updating, and removing packages within the Kubernetes environment.
• Skyhook Custom Resource (SCR): Provides declarative definitions of changes to apply.
• Packages: The actual modifications you want to implement.
• Native Kubernetes Integration: Packages are standard Kubernetes resources compatible with GitOps tools like ArgoCD, Helm, and Flux.
• Autoscaling Support: Ensures newly created nodes are properly configured before becoming schedulable.
• First-Class Upgrades: Deploys changes with minimal disruption, waiting for running workloads to complete when needed.

Benefits

• Enhanced Management: Simplifies the management and updating of Kubernetes clusters.
• Efficiency: Reduces downtime and ensures smooth updates and maintenance.
• Flexibility: Supports various Kubernetes environments, including self-managed, on-prem, and cloud.
• Scalability: Easily scales to manage large clusters with complex configurations.
• Reliability: Provides reliable and consistent updates, protecting important workloads during changes.
