The trivia game application can use Amazon CloudWatch Synthetics to continuously load the webpage and APIs, and alarm when the page does not load or does not render correctly.
Create an SNS topic for notifications about the canary alarms. An email address or to a chat bot can then be subscribed to the topic to receive notifications about canary alarms.
aws sns create-topic --name reinvent-trivia-notifications --region us-east-1
Replace all references to 'reinvent-trivia.com' with your own domain name.
Ideally, use the pipelines in the "pipelines" folder to deploy the canaries. Alternatively, you can use the AWS CLI to deploy.
These instructions require an S3 bucket to store the canary source code, marked as $BUCKET_NAME below.
Package and upload the canary script:
npm install
mkdir -p nodejs/
cp -a node_modules/ nodejs/
cp canary.js nodejs/node_modules/
zip -r trivia-game-canary-code.zip nodejs/
aws s3 cp trivia-game-canary-code.zip s3://$BUCKET_NAME/
Deploy the resources for running a continuous monitoring canary against the test endpoints:
aws cloudformation deploy \
--region us-east-1 \
--template-file template.yaml \
--stack-name TriviaGameCanariesTest \
--capabilities CAPABILITY_NAMED_IAM \
--parameter-overrides Stage=test SourceBucket=$BUCKET_NAME SourceObjectKey="trivia-game-canary-code.zip" WebpageUrl="https://test.reinvent-trivia.com" ApiEndpoint="https://api-test.reinvent-trivia.com/" \
--tags project=reinvent-trivia
Deploy the resources for running a continuous monitoring canary against the production endpoints:
aws cloudformation deploy \

--parameter-overrides Stage=prod SourceBucket=$BUCKET_NAME SourceObjectKey="trivia-game-canary-code.zip" WebpageUrl="https://www.reinvent-trivia.com" ApiEndpoint="https://api.reinvent-trivia.com/" \
