问题 I'm trying to run serverless LibreOffice based on this tutorial. Here is the full python lambda function: import boto3 import os s3_bucket = boto3.resource("s3").Bucket("lambda-libreoffice-demo") os.system("curl https://s3.amazonaws.com/lambda-libreoffice-demo/lo.tar.gz -o /tmp/lo.tar.gz && cd /tmp && tar -xf /tmp/lo.tar.gz") convertCommand = "instdir/program/soffice --headless --invisible --nodefault --nofirststartwizard --nolockcheck --nologo --norestore --convert-to pdf --outdir /tmp" def

问题 I am trying to build a Kibana dashboard fed with twitter data collected via AWS Kinesis firehose where data passes into an S3 bucket which triggers a Lambda function which passes the data to AWS Elastic Search and then to Kibana. I am following this blog https://aws.amazon.com/blogs/big-data/building-a-near-real-time-discovery-platform-with-aws/ The data is loading into the S3 bucket correctly but it never arrives in Kibana, I believe this is because the Lambda function is not being triggered

问题 I want to crawl data from a WebSocket data source, usually WebSocket data is an endless stream, while an AWS Lambda function has a Timout limit, the maximum allowed value is 900 seconds. If my Lambda function acts as a WebSocket client and connects to a WebSocket url, e.g., wss://ws-feed-public.sandbox.pro.coinbase.com , it starts to receive data for 900 seconds and get terminated by then. How to keep my Lamda function running forever? Thanks! Right now I'm running my crawler inside a Linux

问题 I just started using sinon, and I had some initial success stubbing out DynamoDB calls: sandbox = sinon.createSandbox() update_stub = sandbox.stub(AWS.DynamoDB.DocumentClient.prototype, 'update').returns({ promise: () => Promise.resolve(update_meeting_result) }) This works great. But I also need to stub Lambda, and the same approach isn't working: lambda_stub = sandbox.stub(AWS.Lambda.prototype, 'invoke').returns({ promise: () => Promise.resolve({lambda_invoke_result}) // }) With this, I get

问题 I am trying to define a terraform output block that returns the ARN of a Lambda function. The Lambda is defined in a sub-module. According to the documentation it seems like the lambda should just have an ARN attribute already: https://registry.terraform.io/providers/hashicorp/aws/latest/docs/data-sources/lambda_function#arn Using that as a source I thought I should be able to do the following: output "lambda_arn" { value = module.aws_lambda_function.arn } This generates the following error:

问题 I am using a python script from github to run on AWS lambda. I realized that the import boto statements are not working while running inside lambda. Is there way to instruct lambda to load boto2 as well? 回答1: OK, all I had to do was install boto using "pip install module-name -t /path/to/project-dir" per the docs: http://docs.aws.amazon.com/lambda/latest/dg/lambda-python-how-to-create-deployment-package.html Then zipped the files needed for lambda and uploaded. 来源： https://stackoverflow.com

问题 I have a table which has throttled write request at a specified time. I want to understand more about how AWS-SDK handle them. For my current understanding, DynamoDB will return an error to my Lambda. That's why I will have user errors in DynamoDB Table Metrics. However, AWS-SDK has error-handling and retry strategy which helps me to retry and write the throttled requests back to the table. Is it correct? 回答1: Every time your application sends a request that exceeds your capacity you get a

问题 I am trying to perform a document upload using an S3 pre-signed PUT url. I generated the url using java AWS SDK ( GeneratePresignedUrlRequest.java ). This url generation code sits in a lambda function behind AWS API gateway. However I am getting the following error when I copy the generated url in Postman & try to perform an upload. <Error> <Code>AccessDenied</Code> <Message> There were headers present in the request which were not signed </Message> <HeadersNotSigned>host</HeadersNotSigned>

问题 I'm running a lambda function which takes an mp4 video, and adds a watermark of a png image over the top of it in the bottom right hand corner (with a 10px margin). It then outputs that image to a temporary location. It keeps failing with Error code 1 , but that isn't very helpful. I'm using a binary version of ffmpeg that is specified in the main directory of the code. I know that ffmpeg is set up correctly due to using it in another lambda function in this way, which works. But adding an

问题 I have one lambda function within my serverless.yml . It looks somehow like this: functions: clean: handler: app.run events: - schedule: rate(2 hours) It works pretty well and out of the box lambda gets called every 2 hours. When I add new rule in AWS Console and sets the newly created lambda as a target it also works. Both AWS Console and Serverless framework creates on the background policy that events.amazonaws.com service can invoke this specific function. The policy looks somehow like
