For hypervisor-based container runtimes (like Kata Containers, Clear Containers
or runv) a pod will be created in a VM and then create containers within the VM.
When a runtime is requested for container commands like create and start, both
the instal "pause" container and next containers need to be added to the pod
namespace (same VM).
A runtime does not know if it needs to create/start a VM or if it needs to add a
container to an already running VM pod.
This patch adds a way to provide this information through container annotations.
When starting a container or a sandbox, 2 annotations are added:
- type (Container or Sandbox)
- sandbox name
This allow to a VM based runtime to decide if they need to create a pod VM or
container within the VM pod.
