Health checks configuration in GCP - Mini Project: Build & Apply

Health checks configuration

📖 Scenario: You are setting up a Google Cloud Platform (GCP) load balancer to distribute traffic to your web servers. To ensure traffic is only sent to healthy servers, you need to configure health checks that monitor the servers' status.

🎯 Goal: Build a health check configuration in GCP that checks the health of backend instances by sending HTTP requests to a specific path and port.

📋 What You'll Learn

Create a health check resource with a specific name

Set the health check to use HTTP protocol

Configure the health check to check a specific port and request path

Set the check interval and timeout values

💡 Why This Matters

🌍 Real World

Health checks are essential to ensure that load balancers only send traffic to servers that are working properly, improving reliability and user experience.

💼 Career

Cloud engineers and DevOps professionals regularly configure health checks to maintain high availability and fault tolerance in cloud infrastructure.

1

Create the initial health check resource dictionary

Create a dictionary called health_check with the key name set to "my-health-check".

GCP

# Create the health_check dictionary with the name key
# Your code here

Need a hint?

Use a Python dictionary with the key name and value "my-health-check".

2

Add protocol and port configuration

Add the keys type with value "HTTP" and port with value 80 to the health_check dictionary.

GCP

health_check = {
    "name": "my-health-check"
}
# Add type and port keys to health_check
# Your code here

Need a hint?

Add "type": "HTTP" and "port": 80 inside the dictionary.

3

Add request path and timing settings

Add the keys requestPath with value "/health", checkIntervalSec with value 5, and timeoutSec with value 3 to the health_check dictionary.

GCP

health_check = {
    "name": "my-health-check",
    "type": "HTTP",
    "port": 80
}
# Add requestPath, checkIntervalSec, and timeoutSec keys
# Your code here

Need a hint?

Add the keys for the request path and timing inside the dictionary.

4

Complete the health check configuration

Add the key unhealthyThreshold with value 2 and healthyThreshold with value 3 to the health_check dictionary to complete the configuration.

GCP

health_check = {
    "name": "my-health-check",
    "type": "HTTP",
    "port": 80,
    "requestPath": "/health",
    "checkIntervalSec": 5,
    "timeoutSec": 3
}
# Add unhealthyThreshold and healthyThreshold keys
# Your code here

Need a hint?

Set the thresholds for healthy and unhealthy checks.
