问题 I am trying to install airflow on an AWS EC2 instance. The process seems to be pretty well documented by various sources on the web, however, I have run into a problem after I 'pip install' airflow; I get the below error when I execute the command 'airflow initdb': [2019-09-25 13:22:02,329] {__init__.py:51} INFO - Using executor SequentialExecutor Traceback (most recent call last): File "/home/cloud-user/.local/bin/airflow", line 22, in <module> from airflow.bin.cli import CLIFactory File "

问题 In the CloudFormation template I am deploying, I am running a few commands in the UserData block. One of these commands starts up a session for NICE DCV: https://aws.amazon.com/hpc/dcv/ It looks as follows: "UserData": { "Fn::Base64" : { "Fn::Join" : [ "", [ dcv create-session --type virtual ", " --owner ubuntu", " --user ubuntu", " my-session, "\n", "while ! (dcv list-sessions | grep -q 'my-session'); do sleep 1; done\n" ] ] } } First, I create a session with command: $ dcv create-session -

问题 I found this link that talks about separating static data and a web api into a static s3 web server and a bean stalk application for an api and an ec2 web server to create a website. The answer from Charles is accurate, CORS is how you address the problem with moving between the two domains. How to use S3 as static web page and EC2 as REST API for it together? (AWS) The question I have is why you would do this? Some of my thoughts are: Advantage - We use node as the web server for the api and

问题 I am newish to AWS Elastic Beanstalk and this is the first time I have encountered this issue. I tried deploying a new version via zip upload of my app to an instance and the updated completed with errors: "Completed but with Command Line Timeouts", I increased the timeout in the config file and redeployed, after which I got this message. During an aborted deployment, some instances may have deployed the new application version. To ensure all instances are running the same version, re-deploy

问题 I have a function which perform some mathematical operations and need a 16gb GPU system, But this function will not be triggered always and rest of time my system will not be in use. I came to know about AWS Lambda. Can I run GPU based algorithm on Lambda?? So that whenever I need GPU, I will get the system on cloud. I need a little description about it. 回答1: You can't specify the runtime environment for AWS Lambda functions, so no, you can't require the presence of a GPU (in fact the

问题 I'm not a developer so maybe the answer is out there for a different solution but I can't really translate it from python or something else. I'm trying to use the AWS .NET SDK to find an instance and then get the instance's tags. I've gotten as far as being able to determine if an instance is up and running or not. I also see how I can create and delete tags (not in code example below). But I don't see an easy way to actually check if a tag exists and get the value of the tag if it does exist
