Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the HTTP probe path to "/healthz".

Kubernetes

livenessProbe:
  httpGet:
    path: "[1]"
    port: 8080

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

B/status

C/healthz

D/ready

💡 Hint

Common Mistakes

Using a path without a leading slash.

Choosing a path that does not exist in the application.

The HTTP probe path should be set to /healthz to check the health endpoint.

Complete the code to set the HTTP probe port to 8080.

Kubernetes

readinessProbe:
  httpGet:
    path: "/ready"
    port: [1]

💡 Hint

Common Mistakes

Using the wrong port number that the application does not listen on.

Confusing HTTP and HTTPS ports.

The HTTP probe port should match the application's listening port, which is 8080 here.

hard

Fix the error in the HTTP probe configuration by completing the missing field.

Kubernetes

livenessProbe:
  httpGet:
    path: "/health"
    port: 8080
  [1]: 5

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

CperiodSeconds

DinitialDelaySeconds

Attempts:

3 left

💡 Hint

Common Mistakes

Using timeoutSeconds instead of initialDelaySeconds for delay.

Omitting the delay causing probe failures on startup.

The initialDelaySeconds field specifies how long to wait before starting the probe.

4fill in blank

hard

Fill both blanks to configure the readiness probe with a 3-second timeout and a 10-second period.

Kubernetes

readinessProbe:
  httpGet:
    path: "/ready"
    port: 8080
  [1]: 3
  [2]: 10

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

CperiodSeconds

DfailureThreshold

💡 Hint

Common Mistakes

Swapping timeoutSeconds and periodSeconds values.

Using initialDelaySeconds instead of timeoutSeconds.

timeoutSeconds sets how long to wait for a response. periodSeconds sets how often to run the probe.

5fill in blank

hard

Fill all three blanks to configure a liveness probe with a 5-second initial delay, 2-second timeout, and 15-second period.

Kubernetes

livenessProbe:
  httpGet:
    path: "/healthz"
    port: 8080
  [1]: 5
  [2]: 2
  [3]: 15

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

BtimeoutSeconds

CperiodSeconds

DfailureThreshold

💡 Hint

Common Mistakes

Mixing up the timing fields.

Omitting initialDelaySeconds causing early probe failures.

initialDelaySeconds waits before starting probes, timeoutSeconds sets response wait time, and periodSeconds sets probe frequency.
