Node pools and auto scaling in GCP - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the minimum number of nodes in a node pool.

GCP

resource "google_container_node_pool" "primary_nodes" {
  name       = "primary-node-pool"
  cluster    = google_container_cluster.primary.name
  node_count = [1]
}

Common Mistakes

Using a negative number for node_count

Setting node_count to zero which disables the pool

The node_count sets the number of nodes in the pool. It must be a positive integer, like 3.

2fill in blank

medium

Complete the code to enable autoscaling for the node pool.

GCP

resource "google_container_node_pool" "autoscaling_pool" {
  name       = "autoscale-pool"
  cluster    = google_container_cluster.primary.name
  autoscaling {
    min_node_count = 1
    max_node_count = [1]
  }
}

💡 Hint

Common Mistakes

Setting max_node_count less than min_node_count

Using negative numbers for max_node_count

The max_node_count must be greater than or equal to min_node_count. 5 is a reasonable max.

3fill in blank

hard

Fix the error in the autoscaling block by completing the missing field.

GCP

resource "google_container_node_pool" "fixed_pool" {
  name       = "fixed-pool"
  cluster    = google_container_cluster.primary.name
  autoscaling {
    [1] = 2
    max_node_count = 5
  }
}

💡 Hint

Common Mistakes

Using node_count inside autoscaling block

Omitting min_node_count causes errors

The autoscaling block requires min_node_count to set the minimum nodes allowed.

4fill in blank

hard

Fill both blanks to configure autoscaling with a minimum of 2 nodes and a maximum of 6 nodes.

GCP

resource "google_container_node_pool" "scale_pool" {
  name       = "scale-pool"
  cluster    = google_container_cluster.primary.name
  autoscaling {
    min_node_count = [1]
    max_node_count = [2]
  }
}

💡 Hint

Common Mistakes

Swapping min and max values

Setting min higher than max

Set min_node_count to 2 and max_node_count to 6 to allow scaling between these limits.

5fill in blank

hard

Fill all three blanks to create a node pool with autoscaling enabled, minimum 1 node, maximum 4 nodes, and initial node count 2.

GCP

resource "google_container_node_pool" "full_pool" {
  name               = "full-pool"
  cluster            = google_container_cluster.primary.name
  initial_node_count  = [1]
  autoscaling {
    min_node_count = [2]
    max_node_count = [3]
  }
}

💡 Hint

Common Mistakes

Setting initial_node_count outside min-max range

Using max_node_count less than min_node_count

Set initial_node_count to 2, min_node_count to 1, and max_node_count to 4 for proper autoscaling setup.
