How to use Boto3 to remove tags from AWS Glue Resources

In this article, we will see how to remove tags from AWS Glue Resources.

Example

Remove tags “glue-db: tests” in AWS glue database.

 Problem Statement: Use boto3 library in Python to remove tags in AWS Glue Resources.

Approach/Algorithm to solve this problem

• Step 1: Import boto3 and botocore exceptions to handle exceptions.

• Step 2: resource_arn and tags_list are the required parameters in this function.

The format of resource_arn should be as following −

Catalog	arn:aws:glue:region:account-id:catalog
Database	arn:aws:glue:region:account-id:database/database name
Table	arn:aws:glue:region:account-id:table/database name/table name
Connection	arn:aws:glue:region:account-id:connection/connection name
Crawler	arn:aws:glue:region:account-id:crawler/crawler-name
Job	arn:aws:glue:region:account-id:job/job-name
Trigger	arn:aws:glue:region:account-id:trigger/trigger-name
Development endpoint	arn:aws:glue:region:account-id:devEndpoint/development-endpoint-name
Machine learning transform	arn:aws:glue:region:account-id:mlTransform/transform-id

tags_list should be as [“key1,key2…]

• Step 3: Create an AWS session using boto3 lib. Make sure region_name is mentioned in the default profile. If it is not mentioned, then explicitly pass the region_name while creating the session.

• Step 4: Create an AWS client for glue.

• Step 5: Now use the untag_resource function and pass the parameter resource_arn as ResourceArn and tags_list as TagsToRemove.

• Step 6: It returns the response metadata and removes tags in the resources.

• Step 7: Handle the generic exception if something went wrong while removing tags.

Example Code

Use the following code to remove tags −

import boto3
from botocore.exceptions import ClientError

def remove_tags_in_resource(resource_arn, tags_list)
   session = boto3.session.Session()
   glue_client = session.client('glue')
   try:
      response = glue_client.untag_resource(ResourceArn= resource_arn,TagsToRemove=tags_list)
      return response
   except ClientError as e:
      raise Exception("boto3 client error in remove_tags_in_resource: " + e.__str__())
   except Exception as e:
      raise Exception("Unexpected error in remove_tags_in_resource: " + e.__str__())
tags_dict = ["glue-db"]
print(remove_tags_in_resource("arn:aws:glue:us-east-1:1122225*****88:database/test- db",tags_list))

Output

{'ResponseMetadata': {'RequestId': 'c9f418b0-***************-fb96', 'HTTPStatusCode': 200, 'HTTPHeaders': {'date': 'Fri, 02 Apr 2021 08:04:54 GMT', 'content-type': 'application/x-amz-json-1.1', 'content-length': '27', 'connection': 'keep-alive', 'x-amzn-requestid': 'c9f418b0-******************-fb96'}, 'RetryAttempts': 0}}
