💡 Hint

Common Mistakes

Using '256MB' instead of '256Mi'.

Omitting units like 'Mi'.

The correct memory request format in Kubernetes uses units like Mi (mebibytes). '256Mi' means 256 mebibytes.

💡 Hint

Common Mistakes

Using '512MB' which is not recognized.

Leaving out units.

Memory limits require units like 'Mi' for mebibytes. '512Mi' is the correct format.

💡 Hint

Common Mistakes

Using '128MB' instead of '128Mi'.

Omitting units.

The correct memory request must use 'Mi' units. '128Mi' is valid, '128MB' is not.

Fill both blanks to set memory requests and limits correctly.

Kubernetes

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

💡 Hint

Common Mistakes

Using 'MB' units.

Setting limits smaller than requests.

Memory requests and limits must use 'Mi' units. '256Mi' for requests and '512Mi' for limits is correct.

5fill in blank

hard

Fill all three blanks to define a container with memory requests and limits.

Kubernetes

containers:
- name: app
  resources:
    requests:
      memory: [1]
    limits:
      memory: [2]
  image: myapp:latest
  env:
    - name: ENV_VAR
      value: [3]

💡 Hint

Common Mistakes

Using memory units incorrectly.

Not quoting environment variable values.

The container requests 128Mi memory, limits 256Mi, and sets environment variable to 'production'.
