Answer from AI
The term "vanilla Kubernetes" refers to Kubernetes without additional overlays, extensions, or specialized distributions. Essentially, it is a pure, "out-of-the-box" version that complies with the upstream Kubernetes project specifications.
Main characteristics of vanilla Kubernetes:
- No vendor lock-in: Not tied to a specific cloud provider or vendor.
- Basic set of components: Includes only key components such as kube-apiserver, etcd, kube-controller-manager, kube-scheduler, kubelet, and kube-proxy.
- Standard integrations: Uses standard interfaces, such as Container Network Interface (CNI), Container Storage Interface (CSI), and Container Runtime Interface (CRI).
- Manual installation and configuration: Often requires a deeper understanding of internal workings for deployment and management compared to managed services.
- Maximum flexibility: Allows fine-tuning every aspect of the cluster.
Examples of "non-vanilla" Kubernetes include:
- Managed cloud provider services (AKS, EKS, GKE).
- Distributions with their own build or additional tools (OpenShift, Rancher).
- Clusters deployed using third-party tools that add significant abstractions or automation on top of basic Kubernetes.
Choosing vanilla Kubernetes is justified when maximum control over the cluster is required, when avoiding vendor lock-in is necessary, or when there are specific requirements that are difficult to implement in ready-made distributions. However, it requires more time and resources for deployment, maintenance, and security.
