PubSub Lite Topic Retention Should Be Set

Using Console

Using CLI

To remediate the misconfiguration of PubSub Lite Topic Retention for GCP using GCP CLI, follow these steps:

Open the GCP Cloud Shell in your GCP console.
Run the following command to set the retention period for a PubSub Lite topic:
```
gcloud pubsub lite-topics update TOPIC-ID --retention-period PERIOD
```
Replace TOPIC-ID with the ID of the PubSub Lite topic that you want to update, and replace PERIOD with the number of seconds that you want to retain messages in the topic. For example, to set the retention period to 7 days (or 604800 seconds), run the following command:
```
gcloud pubsub lite-topics update my-topic --retention-period 604800
```
Verify that the retention period has been set correctly by running the following command:
```
gcloud pubsub lite-topics describe TOPIC-ID
```
Replace TOPIC-ID with the ID of the PubSub Lite topic that you updated. The output should include a “retentionConfig” section that shows the retention period that you set. For example, the output might look like this:
```
name: projects/my-project/locations/us-central1-a/topics/my-topic
partitionConfig:
  count: 1
  ...
retentionConfig:
  perPartitionBytes: 0
  period: 604800s
state: READY
```
This indicates that the retention period for the topic has been set to 7 days.
Repeat these steps for any other PubSub Lite topics that need to have their retention period set.

By following these steps, you can remediate the misconfiguration of PubSub Lite Topic Retention for GCP using GCP CLI.

Using Python

To remediate the PubSub Lite Topic Retention misconfiguration in GCP using Python, you can follow the below steps:

Install the Google Cloud Pub/Sub Lite client library for Python using pip:

pip install google-cloud-pubsublite

Import the required libraries:

from google.api_core.exceptions import NotFound
from google.cloud.pubsublite import AdminClient, SubscriptionPath, TopicPath
from google.cloud.pubsublite.types import Duration

Set the project ID and location of the Pub/Sub Lite topic:

project_id = "your-project-id"
location = "your-location"
topic_id = "your-topic-id"

Create an instance of the AdminClient class:

admin_client = AdminClient()

Use the TopicPath class to create a topic_path object:

topic_path = TopicPath(project_id, location, topic_id)

Use a try-except block to check if the topic exists:

try:
    topic = admin_client.get_topic(topic_path)
except NotFound:
    print(f"Topic '{topic_path}' not found.")
    return

Set the retention duration for the topic using the update_topic method:

retention_duration = Duration(seconds=604800) # 1 week in seconds
topic.retention_config.period = retention_duration
admin_client.update_topic(topic)

Verify that the retention duration has been set:

print(f"Retention duration set to {topic.retention_config.period.seconds} seconds.")

The complete code to remediate the PubSub Lite Topic Retention misconfiguration in GCP using Python is as follows:

from google.api_core.exceptions import NotFound
from google.cloud.pubsublite import AdminClient, SubscriptionPath, TopicPath
from google.cloud.pubsublite.types import Duration

project_id = "your-project-id"
location = "your-location"
topic_id = "your-topic-id"

admin_client = AdminClient()
topic_path = TopicPath(project_id, location, topic_id)

try:
    topic = admin_client.get_topic(topic_path)
except NotFound:
    print(f"Topic '{topic_path}' not found.")
    return

retention_duration = Duration(seconds=604800) # 1 week in seconds
topic.retention_config.period = retention_duration
admin_client.update_topic(topic)

print(f"Retention duration set to {topic.retention_config.period.seconds} seconds.")
