How to use Boto3 to get tags from an AWS Glue Resources

AWSBoto3PythonServer Side ProgrammingProgramming

In this article, we will see how the users can get the tags associated in AWS Glue Resources.

Example

Get tags “glue-db: tests” from AWS glue database.

 Problem Statement: Use boto3 library in Python to get the tags from AWS Glue Resources.

Approach/Algorithm to solve this problem

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

  • Step 2: resource_arn is the required parameter in this function.

Format of resource_arn should be as following −

Catalogarn:aws:glue:region:account-id:catalog
Databasearn:aws:glue:region:account-id:database/database name
Tablearn:aws:glue:region:account-id:table/database name/table name
Connectionarn:aws:glue:region:account-id:connection/connection name
Crawlerarn:aws:glue:region:account-id:crawler/crawler-name
Jobarn:aws:glue:region:account-id:job/job-name
Triggerarn:aws:glue:region:account-id:trigger/trigger-name
Development endpointarn:aws:glue:region:account-id:devEndpoint/development-endpoint-name
Machine learning transformarn:aws:glue:region:account-id:mlTransform/transform-id
  • 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 get_tags function and pass the parameter resource_arn as ResourceArn.

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

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

Example Code

Use the following code to get the tags −

import boto3
from botocore.exceptions import ClientError

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

Output

{'Tags': {'glue-job': 'test'}, 'ResponseMetadata': {'RequestId': 'c9f418b0-8d02-4a26-*************', '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': 'c9f418b0-8d02-4a26-**************'}, 'RetryAttempts': 0}}
