问题 I need to get the Details of Images AMI's from AWS Console based on their State: Available. When I tried it is getting stuck and not printing any line. Python code 1: conn = boto3.resource('ec2') image = conn.describe_images() print(image) # prints nothing for img in image: image_count.append(img) print("img count ->" + str(len(image_count))) #prints nothing Is there any exact keywords for this Image AMI's Please correct me 回答1: An important thing to realize about AMIs is that every AMI is

问题 I would like to retrieve some meta data I added (using the console x-amz-meta-my_variable) every time I upload an object to S3. I have set up lambda through the console to trigger every time an object is uploaded to my bucket I am wondering if I can use something like variable = event['Records'][0]['s3']['object']['my_variable'] to retrieve this data or if I have to connect back to S3 with the bucket and key and then call some function to retrieve it? Below is the code: from __future__ import

问题 I'm new to Amazon's Boto3 API. I created a basic diagram of my sample architecture shown below, with an ELB, 4 instances, 2 subnets and and 2 target groups in 2 different Availability Zones (2 instances in each target group). I know how to create an EC2 instance, a target group, subnets, and an ELB. But what ELB functions to use, is not clear to me. How I can attach the ELB to other components? Basically, how to add instances to the ELB? I'm not sure what next steps and functions are needed

问题 The package boto3 - Amazon's official AWS API wrapper for python - has great support for uploading items to DynamoDB in bulk. It looks like this: db = boto3.resource("dynamodb", region_name = "my_region").Table("my_table") with db.batch_writer() as batch: for item in my_items: batch.put_item(Item = item) Here my_items is a list of Python dictionaries each of which must have the table's primary key(s). The situation isn't perfect - for instance, there is no safety mechanism to prevent you from

问题 What all changes has to be done while using a function which was using boto2 earlier and how has to be changes to boto3 below is one such function example which is on boto2 and it needs to be changed to boto3 def aws(serviceName, module=boto): conn = connections.get(serviceName) if conn is None: service = getattr(module, serviceName) conn = service.connect_to_region(region) connections[serviceName] = conn return conn 回答1: That code doesn't seem to be doing much. It is simply connecting to an

问题 I'm using this script by mlapida posted here: https://gist.github.com/mlapida/1917b5db84b76b1d1d55#file-ec2-stopped-tagged-lambda-py The script by mlapida does the opposite of what I need, I'm not that familiar with Python to know how to restructure it to make this work. I need to shutdown all EC2 instances that do not have a special tag identifying them. The logic would be: 1.) Identify all running instances 2.) Strip out any instances from that list that have the special tag 3.) Process the

问题 I am trying to download a file from Amazon S3 to a predefined folder in the local machine. This is the code and it works fine. But when the file is saved, it saves with lastname of the path. How should I correct this? import boto3 import os S3_Object = boto3.client('s3', aws_access_key_id='##', aws_secret_access_key='##') BUCKET_NAME = '##' filename2 = [] Key2 = [] bucket = S3_Object.list_objects(Bucket=BUCKET_NAME)['Contents'] download_path = target_file_path = os.path.join('..', 'data', 'lz

问题 Does anybody know of a complete sample as to how to send video to a kinesis video stream, using boto3 sdk? This question was asked initially for both both GetMedia and PutMedia. Now I have got this sample code for the GetMedia part: client = boto3.client('kinesisvideo') response = client.get_data_endpoint( StreamName='my-test-stream', APIName='GET_MEDIA' ) print(response) endpoint = response.get('DataEndpoint', None) print("endpoint %s" % endpoint) if endpoint is not None: client2 = boto3

问题 I am doing a lab on the website LinuxAcademy.com. The Course name is Automating AWS with Lambda, Python, and Boto3 and the specific lab I am having trouble with is Lecture: Importing CSV Files into DynamoDB . In this lab we upload a .csv file into S3, an S3 event is generated in a specified bucket which then kicks off the Lambda function shown below. The function parses the .csv then uploads the contents into DynamoDB. I was originally having issues with Line 23: items = read_csv(download
