Display status information for Deployments in Application Explorer tree

[datho7561]

It would be nice to report status information for deployments. For example, we can include:

• The number of available replicas
• The number of configured replicas
• If the Deployment is in CrashLoopBackoff
• Some way to indicate any other errors the Deployment has run into

For the last two, maybe we could do some sort of warning/error icon, with hover text that gives the specific error message.

As an example of a "Successful" deployment:

...and a "Failing" deployment:

Not sure if I correctly get on how can I detect a "Failed" deployment, as I'm not sure if Pods statuses are really replicated to the according Deployment's element.status.conditions array... A Deployment conditions array looks more like a log of events, like:

  conditions: [
    {
      lastTransitionTime: "2024-05-16T18:42:14Z",
      lastUpdateTime: "2024-05-16T18:42:14Z",
      message: "Deployment has minimum availability.",
      reason: "MinimumReplicasAvailable",
      status: "True",
      type: "Available",
    },
    {
      lastTransitionTime: "2024-05-16T18:41:59Z",
      lastUpdateTime: "2024-05-16T18:42:14Z",
      message: "ReplicaSet \"my-deployment-6b7d4f4794\" has successfully progressed.",
      reason: "NewReplicaSetAvailable",
      status: "True",
      type: "Progressing",
    },
  ],

CrashLoopBackOff status is surely can be find as a Pod status - so we probably should enumerate the available Pods statuses in order to detect its presence, shouldn't we?

@datho7561 WDYT?

I think you might need to list the pods in order to collect this information.
