Amazon IVS + Chime Demo

Prerequisites

• Access to AWS Account with permission to create IAM role, DynamoDB, Lambda, API Gateway, S3, and Cloudformation.
• AWS CLI Version 2
• AWS SAM CLI

Deploy from your local machine

Before you start, run below command to make sure you're in the correct AWS account and configured.

aws configure

For additional help on configuring, please see https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-configure.html

1. Create an S3 bucket

• Replace <my-bucket-name> with your bucket name.
• Replace <my-region> with your region name.

aws s3api create-bucket --bucket <my-bucket-name> --region <my-region> \
--create-bucket-configuration LocationConstraint=<my-region>

2. Pack template with SAM

sam package \
--template-file template.yaml \
--output-template-file packaged.yaml \
--s3-bucket <my-bucket-name>

DO NOT run the output from above command, proceed to next step.

3. Deploy Cloudformation with SAM

Replace <my-stack-name> with your stack name.

sam deploy \
--template-file packaged.yaml \
--stack-name <my-stack-name> \
--capabilities CAPABILITY_IAM

On completion, copy the value of ApiURL and WebSocketURI as you will need it later for your client.

Example of ApiURL: https://xxxxxxxxxx.execute-api.us-west-2.amazonaws.com/Prod/
Example of WebSocketURI: wss://xxxxxxxxxx.execute-api.us-west-2.amazonaws.com/Prod

To retrieve Cloudformation stack outputs again, run below command:

aws cloudformation describe-stacks \
--stack-name <my-stack-name> --query 'Stacks[].Outputs'
