CKAD — Resource Management
Resource Management
Every container in Kubernetes can be given resource requests (guaranteed minimum) and limits (maximum allowed). Getting these right is critical — too low and your app crashes, too high and you waste cluster resources.
This chapter covers the Application Environment, Configuration & Security domain (25% of the CKAD exam).
