Using Console

Sure, here are the step-by-step instructions to remediate the PubSub Lite Topic partition count misconfiguration for GCP using the GCP console:
  1. Open the GCP Console and navigate to the Pub/Sub Lite Topics page.
  2. Select the Pub/Sub Lite Topic for which you want to remediate the partition count misconfiguration.
  3. Click on the “Edit” button at the top of the page.
  4. In the “Edit topic” dialog box, scroll down to the “Partition count” section.
  5. Set the partition count to at least 1.
  6. Click on the “Save” button to save the changes.
That’s it! The Pub/Sub Lite Topic partition count misconfiguration has now been remediated for GCP using the GCP console.

​

To remediate the misconfiguration “PubSub Lite Topic Partition Count Should Be At Least 1” for GCP using GCP CLI, follow these steps:
  1. Open the Cloud Shell on GCP console.
  2. Run the following command to list all the Pub/Sub Lite topics in your project: 
gcloud pubsub lite-topics list --location=LOCATION --project=PROJECT_ID
Replace LOCATION with the location of your Pub/Sub Lite topic and PROJECT_ID with your GCP project ID.
  1. Choose the Pub/Sub Lite topic that you want to remediate and run the following command to update the partition count to at least 1:
gcloud pubsub lite-topics update TOPIC_ID --location=LOCATION --partition-count=1 --project=PROJECT_ID
Replace TOPIC_ID with the ID of the Pub/Sub Lite topic that you want to remediate, LOCATION with the location of your Pub/Sub Lite topic, and PROJECT_ID with your GCP project ID.
  1. Verify that the partition count has been updated by running the following command:
gcloud pubsub lite-topics describe TOPIC_ID --location=LOCATION --project=PROJECT_ID
Replace TOPIC_ID with the ID of the Pub/Sub Lite topic that you want to remediate, LOCATION with the location of your Pub/Sub Lite topic, and PROJECT_ID with your GCP project ID.This should remediate the misconfiguration “PubSub Lite Topic Partition Count Should Be At Least 1” for GCP using GCP CLI.
To remediate the PubSub Lite Topic Partition Count should be at least 1 for GCP, you can use the following Python code:
  1. First, you need to import the necessary libraries:
from google.cloud import pubsub_v1
from google.api_core import exceptions
  1. Then, you need to create a PublisherClient object:
publisher_client = pubsub_v1.PublisherClient()
  1. Next, you need to get the topic path:
project_id = "your-project-id"
topic_name = "your-topic-name"
topic_path = publisher_client.topic_path(project_id, topic_name)
  1. After that, you need to get the current topic configuration:
try:
    topic = publisher_client.get_topic(request={"topic": topic_path})
except exceptions.NotFound:
    print(f"Topic {topic_path} not found.")
    return
  1. Then, you need to check if the partition count is less than 1:
if topic.partition_config.count < 1:
    topic.partition_config.count = 1
  1. Finally, you need to update the topic with the new configuration:
update_mask = {"paths": ["partition_config.count"]}
try:
    publisher_client.update_topic(topic=topic, update_mask=update_mask)
    print(f"Topic {topic_path} partition count updated to {topic.partition_config.count}.")
except exceptions.GoogleAPICallError:
    print(f"Failed to update topic {topic_path}.")
The complete Python code to remediate the PubSub Lite Topic Partition Count should be at least 1 for GCP would look like this:
from google.cloud import pubsub_v1
from google.api_core import exceptions

publisher_client = pubsub_v1.PublisherClient()

project_id = "your-project-id"
topic_name = "your-topic-name"
topic_path = publisher_client.topic_path(project_id, topic_name)

try:
    topic = publisher_client.get_topic(request={"topic": topic_path})
except exceptions.NotFound:
    print(f"Topic {topic_path} not found.")
    exit()

if topic.partition_config.count < 1:
    topic.partition_config.count = 1

update_mask = {"paths": ["partition_config.count"]}
try:
    publisher_client.update_topic(topic=topic, update_mask=update_mask)
    print(f"Topic {topic_path} partition count updated to {topic.partition_config.count}.")
except exceptions.GoogleAPICallError:
    print(f"Failed to update topic {topic_path}.")
