Resource Requirement

---

• Resource Requirements tells how much CPU and memory your container needs.
• There are two parts:
  • requests → Minimum needed. Scheduler uses this to find a node.
  • limits → Maximum allowed. Container can’t use more than this.

apiVersion: v1
kind: Pod
metadata:
  name: mypod
spec:
  containers:
  - name: myapp
    image: nginx
    resources:
      requests:
        memory: "64Mi"
        cpu: "250m"
      limits:
        memory: "128Mi"
        cpu: "500m"

• This means:
  • Container needs at least 64Mi of RAM and 0.25 CPU cores
  • It can use up to 128Mi RAM and 0.5 CPU cores
