Container Apps scaling rules in Azure - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

Complete the code to set the minimum number of container app replicas.

💡 Hint

Common Mistakes

Setting minReplicas to a positive number prevents scaling down to zero.

Using a very high minReplicas wastes resources.

Setting minReplicas to 0 allows the container app to scale down to zero instances when idle.

Complete the code to set the maximum number of container app replicas.

Azure

maxReplicas: [1]

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

💡 Hint

Common Mistakes

Setting maxReplicas to 0 disables scaling up.

Setting maxReplicas too low limits app performance.

Setting maxReplicas to 10 limits the container app to scale up to 10 instances.

Fix the error in the CPU-based scaling rule threshold value.

Azure

cpu: [1]

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

💡 Hint

Common Mistakes

Using 0.75 instead of 75 (fraction instead of percentage) causes configuration errors.

Negative CPU values are invalid.

The CPU threshold should be a percentage between 0 and 100 representing % of CPU usage (e.g., 75).

4fill in blank

hard

Fill both blanks to configure HTTP request-based scaling with correct values.

Azure

http: {
  concurrency: [1],
  requestsPerSecond: [2]
}

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

💡 Hint

Common Mistakes

Swapping concurrency and requests per second values.

Setting concurrency too high causes overload.

Concurrency is set to 10 and requests per second to 100 for balanced scaling.

5fill in blank

hard

Fill all three blanks to define a scaling rule with CPU, memory, and HTTP triggers.

Azure

scalingRules: {
  cpuThreshold: [1],
  memoryThreshold: [2],
  httpRequests: [3]
}

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

💡 Hint

Common Mistakes

Using values greater than 100 for CPU or memory thresholds.

Confusing HTTP requests with CPU or memory thresholds.

CPU threshold is 65%, memory threshold 80%, and HTTP requests trigger at 150 requests per second.
