Settings Memory and CPU for container

Desc:

• Basic setting for memory and CPU in container

• How basic knowledge is very important

Measurement Unit

The most important thing is that we have to know the unit of each one:

• CPU: is measure by CPU unit

• Memory: Mebibyte, Gibibyte,...

How to setting them

With CPU:

• It's a float: cpu: "0.5" or cpu: "1"

• "0.5" can represent like "500m"

With Memory:

• Mebibyte: Mi

• Gibibyte: Gi

apiVersion: v1
kind: Pod
metadata:
  name: example-pod
spec:
  containers:
  - name: example-container
    image: example-image
    resources:
      requests:
        memory: "512Mi"  # Memory request
        cpu: "250m"      # CPU request (0.25 CPU units)
      limits:
        memory: "1Gi"    # Memory limit
        cpu: "500m"      # CPU limit (0.5 CPU units)
    ports:
    - containerPort: 8080  # Specify your socket's port here

What is important here

I spend so much time on how to setting them just because of misunderstood the measurement unit and setting them incorrectly.
