Pubsublite topic partition count remediation

Using Console

Using CLI

To remediate the misconfiguration “PubSub Lite Topic Partition Count Should Be At Least 1” for GCP using GCP CLI, follow these steps:

Open the Cloud Shell on GCP console.
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.

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.

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.

Using Python

To remediate the PubSub Lite Topic Partition Count should be at least 1 for GCP, you can use the following Python code:

First, you need to import the necessary libraries:

from google.cloud import pubsub_v1
from google.api_core import exceptions

Then, you need to create a PublisherClient object:

publisher_client = pubsub_v1.PublisherClient()

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)

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

Then, you need to check if the partition count is less than 1:

if topic.partition_config.count < 1:
    topic.partition_config.count = 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}.")
