Our article provides an overview of these components and their roles in supporting containerized applications in a Kubernetes cluster. To properly understand this article, you should have an understanding of the Kubernetes control plane.
Container runtime is responsible for tasks like pulling images from a repository and isolating resources for containers.
Kubelet acts as the primary node agent, ensuring that containers for the pods assigned to its node are running. It interacts with the container runtime using the Container Runtime Interface (CRI) to manage containerized workloads.
Kube-proxy do handles networking by maintaining network rules for pod communication. It watches Service and Endpoint resources and updates iptables rules for packet routing within the Linux kernel.
Service Resources provide stable IP addresses for connecting to pods, facilitating communication within or outside the clusters. Services work with Endpoints resources to route client requests to the appropriate pods.
