In Kubernetes, SSH access is inherently directed at individual containers within a pod, not at the pod itself or at a service.
Therefore, comparing SSH access to a pod and to a service is meaningless.
- A pod is the smallest deployable unit in Kubernetes and can contain one or more containers.
- A service is an abstraction that defines a logical set of pods and a policy by which to access them.
- SSH access is targeted at containers within a pod to execute commands
- Services manage network access to pods but do not handle SSH connections directly.
