1. Login to your AWS console and navigate to the Elasticsearch service.
2. Select the Elasticsearch domain that you want to remediate.
3. Click on the “Modify” button.
4. Scroll down to the “EBS Volume” section.
5. Increase the “EBS Volume Size” to provide more storage space.
6. Click on the “Save Changes” button.
7. Wait for the Elasticsearch domain to update and the new storage space to be available.
8. Verify that the Elasticsearch domain now has free storage space by checking the Elasticsearch dashboard or running a query.

​

1. Open the AWS CLI on your local machine or use the AWS CLI in the AWS Management Console.
2. Run the following command to list all the Elasticsearch domains in your AWS account:

aws es list-domain-names

3. Identify the Elasticsearch domain that has the misconfiguration of not having free storage space.
4. Run the following command to update the Elasticsearch domain configuration and set the storage type to EBS and the EBS volume size to a value greater than the current storage usage:

aws es update-elasticsearch-domain-config --domain-name <domain-name> --ebs-options EBSEnabled=true,VolumeSize=<new-volume-size>

5. Wait for the Elasticsearch domain to be updated. This may take several minutes.
6. Run the following command to verify that the Elasticsearch domain has free storage space:

aws es describe-elasticsearch-domain --domain-name <domain-name> --query 'DomainStatus.EBSOptions.VolumeSize'

7. Repeat steps 4-6 for any other Elasticsearch domains that have the misconfiguration of not having free storage space.

1. Import the necessary Python modules:

import boto3

2. Initialize a boto3 Elasticsearch client:

es = boto3.client('es')

3. Get the Elasticsearch domain name:

domain_name = 'your_domain_name'

4. Get the Elasticsearch domain configuration:

domain_config = es.describe_elasticsearch_domain(DomainName=domain_name)

5. Get the current storage space usage:

storage_used = domain_config['DomainStatus']['EBSOptions']['VolumeSize'] - domain_config['DomainStatus']['EBSOptions']['FreeSpace']

6. Get the maximum storage space limit:

storage_limit = domain_config['DomainStatus']['EBSOptions']['VolumeSize']

7. Calculate the required free storage space:

required_free_space = int(storage_limit * 0.2) # 20% of total storage limit

8. If the current storage space usage is greater than or equal to the required free storage space, then increase the storage limit:

if storage_used >= required_free_space:
    new_storage_limit = storage_limit + required_free_space
    es.update_elasticsearch_domain_config(DomainName=domain_name, EBSOptions={'EBSEnabled': True, 'VolumeSize': new_storage_limit})

9. Print a message indicating whether the storage limit was increased:

if storage_used >= required_free_space:
    print(f"The storage limit for Elasticsearch domain {domain_name} has been increased to {new_storage_limit} GB.")
else:
    print(f"The Elasticsearch domain {domain_name} has sufficient free storage space.")
