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}}
