CPU requests and limits in Kubernetes - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set a CPU request of 500m in the container spec.

Kubernetes

resources:
  requests:
    cpu: [1]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using '0.5' instead of '500m' (equivalent, but task expects millicores notation).

Using '500' means 500 cores, which is too large.

CPU requests can be specified in millicores, so 500m means 0.5 CPU cores. Note: 0.5 is equivalent.

2fill in blank

medium

Complete the code to set a CPU limit of 1 core in the container spec.

Kubernetes

resources:
  limits:
    cpu: [1]

Drag options to blanks, or click blank then click option'

D0.1

💡 Hint

Common Mistakes

Using '1m' means 0.001 CPU, which is too low.

Using '0.1' is valid but not the requested 1 core.

The CPU limit can be set as 1 to mean 1 full CPU core. Note: 1000m is equivalent.

Fix the error in the CPU request value to be valid.

💡 Hint

Common Mistakes

Using '500' means 500 cores, which is too large.

Using words like 'five hundred' is invalid.

CPU requests can be specified in cores or millicores like 500m (0.5 cores). Plain numbers like '500' are valid but mean 500 cores, usually too large. Note: 0.5 is equivalent to 500m.

4fill in blank

hard

Fill both blanks to set CPU request to 250m and CPU limit to 500m.

Kubernetes

resources:
  requests:
    cpu: [1]
  limits:
    cpu: [2]

Drag options to blanks, or click blank then click option'

A250m

B500m

D100m

💡 Hint

Common Mistakes

Swapping request and limit values.

Using whole numbers instead of millicores.

CPU request is set to 250m (0.25 cores) and limit to 500m (0.5 cores).

5fill in blank

hard

Fill all three blanks to set CPU request to 100m, CPU limit to 200m, and memory limit to 512Mi.

Kubernetes

resources:
  requests:
    cpu: [1]
  limits:
    cpu: [2]
    memory: [3]

Drag options to blanks, or click blank then click option'

A100m

B200m

C512Mi

D1Gi

Attempts:

💡 Hint

Common Mistakes

Using '512M' instead of '512Mi' for memory.

Mixing CPU and memory units.

CPU request is 100m, CPU limit is 200m, and memory limit is 512Mi.
