Do Kubernetes Components Run Inside Containers?

Great question! You’re right to question this. On managed services like EKS, GKE, or AKS, the control plane components typically run outside the cluster on the provider's infrastructure. In self-managed setups, like those configured with kubeadm, they mostly run as static pods. This means they are indeed in containers, but initiated by the kubelet rather than treated as standard services. If you're diving deeper, hands-on communities can provide lots of practical examples and support, so keep exploring!

It really depends on how you set up your cluster. If you're using kubeadm (which I recommend), most components run as static pods. You can find their YAML files in /etc/kubernetes/manifests. However, the kubelet itself runs as a service. You can check if it's active by running `systemctl status kubelet`. If you go the route of building a cluster from scratch, the components typically run as services rather than pods. So, seriously, use kubeadm if you can! Also, don't always rely on AI for this. I've gotten some mixed answers from AI when asking about Kubernetes.

Just a thought: If you're going to rely on AI for learning, try to ask at least three different chatbots like Gemini, ChatGPT, or Sonnet. Everyone might give you a slightly different perspective, which can help clarify things. Also, Google can provide great resources, especially for architectures and diagrams. Sometimes I skipped the docs and jumped straight into installing Kubernetes (like using k3s) to get hands-on experience. Including keywords like 'best practices' or 'production grade' in your searches can also be super helpful!

Generally, no. The components operate as services on the control plane nodes directly rather than within containers. Some unique setups might run them as pods for a concept called kubeception, but that's a bit unconventional—most setups don't go that route.

Yes, in modern Kubernetes setups using kubeadm and similar tools, many components run as pods. These are managed via the kubelet manifests directory, so they do indeed run inside containers.

It varies. Some distributions, like Kind, run components in containers, while others like K3s have them all bundled into a single binary. The important thing is to realize that these components need to run somewhere, and you can choose where they operate based on your setup choice.
