Lb global health check configurations remediation

Using Console

Using CLI

To remediate the misconfiguration of Right Health Check Configurations Should Be Used For Load Balancer Global Health Checks in GCP using GCP CLI, follow the below steps:

Open the Cloud Shell in your GCP console.
Run the following command to list all the load balancers in your project:

gcloud compute target-pools list

Choose the target pool for which you want to configure health checks.
Run the following command to configure a health check for the target pool:

gcloud compute health-checks create http [HEALTH_CHECK_NAME] --port [PORT_NUMBER] --request-path [REQUEST_PATH]

Replace [HEALTH_CHECK_NAME] with the name you want to give to the health check, [PORT_NUMBER] with the port number on which the target is listening, and [REQUEST_PATH] with the path to the health check page.

Run the following command to add the health check to the target pool:

gcloud compute target-pools add-health-checks [TARGET_POOL_NAME] --health-check [HEALTH_CHECK_NAME] --global

Replace [TARGET_POOL_NAME] with the name of the target pool you want to configure and [HEALTH_CHECK_NAME] with the name of the health check you created in step 4.

Verify the health check configuration by running the following command:

gcloud compute target-pools get-health [TARGET_POOL_NAME]

Replace [TARGET_POOL_NAME] with the name of the target pool you configured in step 5.By following these steps, you can remediate the misconfiguration of Right Health Check Configurations Should Be Used For Load Balancer Global Health Checks in GCP using GCP CLI.

Using Python

To remediate this misconfiguration for GCP using Python, you can follow these steps:

First, you need to create a health check object with the correct configurations. Here’s an example code:

from google.cloud import compute_v1

compute = compute_v1.ComputeClient()

# Define the health check configuration
health_check_config = {
    "check_interval_sec": 10,
    "timeout_sec": 5,
    "healthy_threshold": 2,
    "unhealthy_threshold": 2,
    "type": "HTTP",
    "http_health_check": {
        "port": 80,
        "request_path": "/",
        "port_name": "http"
    }
}

# Create the health check object
health_check = {
    "name": "my-http-health-check",
    "description": "Health check for HTTP load balancer",
    "check_interval_sec": health_check_config["check_interval_sec"],
    "timeout_sec": health_check_config["timeout_sec"],
    "healthy_threshold": health_check_config["healthy_threshold"],
    "unhealthy_threshold": health_check_config["unhealthy_threshold"],
    "type": health_check_config["type"],
    "http_health_check": health_check_config["http_health_check"]
}

# Create the health check
operation = compute.health_checks().insert(
    project="my-project",
    body=health_check
).execute()

# Wait for the operation to complete
operation_name = operation["name"]
operation_status = compute.zone_operations().get(
    project="my-project",
    operation=operation_name
).execute()["status"]

while operation_status != "DONE":
    operation_status = compute.zone_operations().get(
        project="my-project",
        operation=operation_name
    ).execute()["status"]

Once the health check object is created, you need to update the load balancer to use this new health check. Here’s an example code:

# Get the load balancer object
load_balancer = compute.url_maps().get(
    project="my-project",
    urlMap="my-load-balancer"
).execute()

# Update the load balancer to use the new health check
load_balancer["healthChecks"] = ["my-http-health-check"]

# Update the load balancer
operation = compute.url_maps().update(
    project="my-project",
    urlMap="my-load-balancer",
    body=load_balancer
).execute()

# Wait for the operation to complete
operation_name = operation["name"]
operation_status = compute.zone_operations().get(
    project="my-project",
    operation=operation_name
).execute()["status"]

while operation_status != "DONE":
    operation_status = compute.zone_operations().get(
        project="my-project",
        operation=operation_name
    ).execute()["status"]

These steps will create a new health check object with the correct configurations and update the load balancer to use this new health check.
