Query related to VPA in the exam

Kubernetes
#1

Hi Team,

Could you please explain the following term used “lowerbound”, “target”, “uncapped” in VPA? Modules in the course doesn’t explain much on this.

recommendation:
    containerRecommendations:
    - containerName: flask-app-4
      lowerBound:
        cpu: 290m
      target:
        cpu: 548m
      uncappedTarget:
        cpu: 548m
      upperBound:
        cpu: "1"

Thanks,
Sakshi

You might get some info for all the fields in the API reference docs of the project in the GitHub repo.

The best way to know about a field would be using the kubectl explain command.
For these status fields, you can use k explain vpa.status.recommendation.containerRecommendations to get a brief description and required value type for each field.
