问题 I have websockets setup with aws api gateway, I also have an ec2 instance running with node and express and ws websockets, I am able to send a message with wscat to the apigateway wss url and it shows up in the ec2 instance, but if I send a message from the ec2 instance it doesnt show up back in the wscat. I followed this tut to setup the apigateway https://aws.amazon.com/blogs/compute/announcing-websocket-apis-in-amazon-api-gateway/ Here is the ec2 instance code. I am not quite sure what

问题 Context: I am using Circle CI's aws-ecs/deploy-service-update orb to deploy my docker container by pulling the latest image in AWS ECR and deploy it in AWS ECS with AWS EC2 instance. This container is a Machine Learning model that accepts API requests at TCP port 3000(I am using fastAPI for this) and returns the predictions. After I deployed it I couldn't send requests to the public IP of the container instance of the task that deploys the container at port 3000 (This IP is not my EC2

问题 Problem: Recently we encountered a problem with respect to maximum number of resources that you can declare in a single CloudFormation template. A template can support a maximum of 200 resources and we are very close to reach that limit. To specify more resources, we need to separate our template into multiple templates by using Nested Stacks, We are evaluating a best approach to breakdown the template. Our approach: We have created a nested stack from our main stack and removed some of the

问题 Do EC2 instances change the IP address for your instance each time you stop/start the instance? Is there a way to keep the IP address constant? 回答1: Yes , there is a way: Elastic IP Addressing. AWS instances are launched with a dynamic IP address by default, which means that the IP address changes every time the server is stopped and restarted. In many cases, this is not desired and so, users also have the option to assign the server a static IP address (also known as an “elastic IP”). 3
