Phillip J. Fry leads a small IT at a moderately sized firm. His company has a modest data center.

Phillip wants to run application ''. In order to meet regulatory requirements he needs to run the application 'in house'. Phillip has deployed '' to a a Kubernetes cluster running with spare capacity. Phillip wants to list the container Endpoints and look at the details of what the frontend service Endpoint is connected to.

Hermes Conrad is the VP of engineering at a large corporation.

Hermes is exploring Kubernetes as a way to orchestrate containers. He has just setup a Kubernetes master, and wants to add further machines. Hermes has no deep knowledge of Kubernetes, but Docker was seemed easy to discover hands-on, and wants to do the same here. Hermes has deployed services to a Kubernetes cluster, and wants to look at all the objects it consists of.

    • Capacity: CPU, Memory, Pods
    • Status: Ready state
    • Operating system
  • Services:
    • Cluster address/port
    • Endpoint address/port
    • Status
  • Pods:
    • Containers sublisting
      • Ports/protocol
      • Volume mount names
      • State: Restart count
    • Status
    • Age
  • Replication Controllers
    • Replicas x of y

The current wireframes for this are very minimal:



  • Later: add labels and label selector, search, filtering
  • Later: Use color to highlight status
  • Later: Add other objects besides basic kube objects
