Invalidation AWS CDN Using Boto3
This post describe how to remove files from CloudFront edge caches before it expires using python boto3
To invalidate files, specify either the path for individual files or a path that ends with the * wildcard, which might apply to one file or to many, as shown in the following examples:
/images/image1.jpg/images/image*/images/*
- Using python boto3 invalidatecdn_demo.py ``` import boto3 import time import sys
""" Invalidate CDN at s3://static/demo/src """ DISTRIBUTION_ID = 'A1AA1AA11A11AA'
client = boto3.client('cloudfront')
def create_invalidation(): res = client.create_invalidation( DistributionId=DISTRIBUTION_ID, InvalidationBatch={ 'Paths': { 'Quantity': 1, 'Items': [ '/demo/src/*' ] }, 'CallerReference': str(time.time()).replace(".", "") } ) invalidation_id = res['Invalidation']['Id'] return invalidation_id
def get_invalidation_status(inval_id): res = client.get_invalidation( DistributionId=DISTRIBUTION_ID, Id=inval_id ) return res['Invalidation']['Status']
def run(): the_id = create_invalidation() count = 0 while True: status = get_invalidation_status(the_id) if status == 'Completed': print("Completed, id: {}".format(the_id)) break elif count < 10: count += 1 time.sleep(30) else: print("Timeout, please check CDN") sys.exit(1)
if name == 'main': run()
