Answer from AI

In Kubernetes, the Limit parameter in the context of a Pod (more specifically, a container within a Pod) sets the maximum resources that the container can use. This usually pertains to CPU and memory (RAM). If the container exceeds the specified limit, Kubernetes may restrict its resource usage or even restart the container.

For example, if a memory limit of 500Mi is set, the container cannot use more than 500 megabytes of RAM. This helps prevent a situation where one container consumes too many resources and affects the operation of others.

Example in a Pod (container) manifest:

resources:
  limits:
    memory: "500Mi"
    cpu: "1"
