When you create a pod in Kubernetes, several components work together to make it happen. The kubelet is the primary node agent that runs on each node in your cluster. It's responsible for making sure that containers are running in a pod as expected.

The image downloading process works like this:

> First, the kube-apiserver receives your request to create a pod

> The kube-scheduler determines which node should run the pod

> Then, the kubelet on that selected node takes over

The kubelet communicates with the container runtime (which could be containerd, CRI-O, or previously Docker) to:

> Pull the requested container images from registries

> Create the containers according to pod specifications

> Monitor their health

While containerd is closely involved in this process as a container runtime, it's the kubelet that initiates the image pull requests and manages the overall pod lifecycle. The kubelet tells containerd what to do.
