AKS - Default Workloads

Introduction

Default Workloads Running on AKS

• Namespace: kube-system
• Kind: Deployment

1. CoreDNS
   • CoreDNS is a DNS server that provides DNS resolution for services and pods within the Kubernetes cluster.
   • It translates service names and domain names into IP addresses, allowing pods to discover and communicate with each other and with services.
   • CoreDNS is usully configured to use a ConfigMap that defines its behavior and DNS rules.
2. CoreDNS-Autoscaler
   • CoreDNS-Autoscaler is responsible for scaling the CoreDNS deployment based on the load.
   • It typically uses the metrics provided by the CoreDNS pods to determine when to scale up or down.
3. Konnectivity-Agent
   • Konnectivity is a component used for connectivity between the control plane and the nodes in the cluster.
   • It helps facilitate communication between the API server and the nodes, especially in private clusters or clusters with advanced networking configurations.
4. Metrics Server
   • Metrics Server is a cluster-wide aggregator of resource usage data, such as CPU and memory metrics.
   • Metrics Server scrapes metrics from the kubelet on each node and provides this data to the Kubernetes API server for use in autoscaling and monitoring.
