Image registry resource sharing among container orchestrators in a virtualized computing system

A method of managing access to a container image registry in a virtualized computing system, the container image registry managing container images for deploying containers in a host cluster, the host cluster including hosts and a virtualization layer executing on hardware platforms of the hosts, the virtualization layer supporting execution of virtual machines (VMs), the method comprising:

• creating, by a registry agent, a robot account in the container image registry;
• creating, by the registry agent, image secrets in a master server of an orchestration control plane integrated with the virtualization layer, the orchestration control plane including a master server executing in a first VM of the VMs;
• and
• providing the image secrets to a guest cluster managed by the orchestration control plane and executing in second VMs of the VMs, the image secrets enabling the guest cluster to access the container image registry through the robot account.
