Rds clusters parameters pending reboot remediation

Using Console

Using CLI

To remediate the RDS Cluster Parameter Groups Pending Reboot, you need to restart your RDS instances for the changes to take effect. Here are the steps to do it using AWS CLI:

Identify the RDS Instances that need rebooting: The first step is to identify which RDS instances are in the pending reboot state. This can be done by looking at the RDS dashboard in the AWS Management Console or by running the following AWS CLI command:
```
aws rds describe-db-instances --query "DBInstances[?DBParameterGroups[?PendingRebootDBParameterChanges!=`null`]].DBInstanceIdentifier"
```
Reboot the RDS Instances: Once you have identified the RDS instances that need rebooting, you can reboot them using the following AWS CLI command:
```
aws rds reboot-db-instance --db-instance-identifier your-db-instance-identifier
```
Replace ‘your-db-instance-identifier’ with the actual identifier of your RDS instance.
Verify the Changes: After the RDS instances have been rebooted, you can verify that the parameter group changes have taken effect by running the following AWS CLI command:
```
aws rds describe-db-instances --query "DBInstances[?DBParameterGroups[?PendingRebootDBParameterChanges==`null`]].DBInstanceIdentifier"
```
This command will return the identifiers of all RDS instances that do not have any pending parameter group changes.
Repeat the Process: If you have multiple RDS instances that need rebooting, you will need to repeat steps 2 and 3 for each one.

Remember, rebooting an RDS instance can cause a brief outage for your database, so you should plan to do this during a maintenance window or a time when the impact on your users will be minimal.

Using Python

To remediate the “RDS Cluster Parameter Groups Pending Reboot” issue in AWS, you can use the AWS SDK for Python, known as Boto3. Here’s a step-by-step guide:

First, you need to install the AWS SDK for Python (Boto3). Open your terminal and type the following command:
```
pip install boto3
```

Import the necessary libraries in your Python script:

import boto3
from botocore.exceptions import NoCredentialsError

Create a session using your AWS credentials. Replace ‘your_access_key’, ‘your_secret_key’, and ‘your_region’ with your actual AWS credentials.
```
session = boto3.Session(
    aws_access_key_id='your_access_key',
    aws_secret_access_key='your_secret_key',
    region_name='your_region'
)
```
Create a client for RDS:
```
rds = session.client('rds')
```

Now, get a list of all DB instances:

try:
    response = rds.describe_db_instances()
except NoCredentialsError:
    print("No AWS credentials found")

Iterate over the DB instances and reboot the ones with pending parameter changes:

for instance in response['DBInstances']:
    if instance['PendingModifiedValues']:
        try:
            rds.reboot_db_instance(DBInstanceIdentifier=instance['DBInstanceIdentifier'])
            print(f"Reboot initiated for {instance['DBInstanceIdentifier']}")
        except Exception as e:
            print(f"Error rebooting {instance['DBInstanceIdentifier']}: {e}")

Please remember that rebooting a DB instance results in a momentary outage, during which the DB instance status is set to rebooting.Also, ensure that you have the necessary permissions to perform these actions, and always follow the principle of least privilege. You should only grant the permissions necessary to perform a task.
