Replace [URL_MAP_NAME] with the name of the URL map that needs to be modified, [SERVICE_NAME] with the name of the default service associated with the URL map, and [SSL_CERTIFICATE_NAME] with the name of the SSL certificate to be used for HTTPS connections.
After running the above command, the URL map will be updated to accept HTTPS connections. You can verify the changes by running the following command:
Copy
Ask AI
gcloud compute url-maps describe [URL_MAP_NAME]
This command will display the updated configuration of the URL map.
Note: Before running the above commands, make sure you have the necessary permissions to modify the URL maps in the project.
Using Python
To remediate the misconfiguration of Load Balancer Global Urlmaps not accepting HTTPS connections in GCP using Python, follow the steps below:
Import the necessary libraries:
Copy
Ask AI
from google.cloud import compute_v1from google.protobuf.json_format import MessageToDict
Loop through the URL maps and check if HTTPS is enabled:
Copy
Ask AI
for urlmap in urlmaps.get("items", []): urlmap_name = urlmap["name"] urlmap = compute_client.url_maps().get(project=project, urlMap=urlmap_name).execute() urlmap_dict = MessageToDict(urlmap, preserving_proto_field_name=True) if urlmap_dict.get("hostRules"): for host_rule in urlmap_dict["hostRules"]: if host_rule.get("pathMatcher"): path_matcher = host_rule["pathMatcher"] if path_matcher.get("defaultService"): default_service = path_matcher["defaultService"] if default_service.startswith("https://"): print(f"HTTPS is enabled for URL map {urlmap_name}") else: print(f"HTTPS is not enabled for URL map {urlmap_name}") else: print(f"No default service found for path matcher in URL map {urlmap_name}") else: print(f"No path matcher found for host rule in URL map {urlmap_name}") else: print(f"No host rules found in URL map {urlmap_name}")
If HTTPS is not enabled, update the URL map to accept HTTPS connections:
Copy
Ask AI
urlmap_name = "your-url-map-name"urlmap = compute_client.url_maps().get(project=project, urlMap=urlmap_name).execute()urlmap_dict = MessageToDict(urlmap, preserving_proto_field_name=True)if urlmap_dict.get("hostRules"): for host_rule in urlmap_dict["hostRules"]: if host_rule.get("pathMatcher"): path_matcher = host_rule["pathMatcher"] if path_matcher.get("defaultService"): default_service = path_matcher["defaultService"] if default_service.startswith("http://"): path_matcher["defaultService"] = default_service.replace("http://", "https://") urlmap_body = {"hostRules": urlmap_dict["hostRules"]} compute_client.url_maps().patch(project=project, urlMap=urlmap_name, body=urlmap_body).execute() print(f"HTTPS enabled for URL map {urlmap_name}") else: print(f"HTTPS already enabled for URL map {urlmap_name}") else: print(f"No default service found for path matcher in URL map {urlmap_name}") else: print(f"No path matcher found for host rule in URL map {urlmap_name}")else: print(f"No host rules found in URL map {urlmap_name}")
Note: Replace “your-project-id” and “your-url-map-name” with the actual project ID and URL map name in the code. Also, make sure you have the necessary permissions to update the URL map.
