SAM application that serves as backend for www.awsdingler.com.
Deployment config is found in samconfig.toml. This is to run sam deploy to create your own personal developer stack. Deployments to DEV and PROD are handled automatically by the pipeline.
Examples:
sam local invoke KubernetesDashboard \
--event events/k8s.json \
--env-vars env.json
sam local invoke HelloWorldFunction \
--event events/hello.json \
--env-vars env.json
sam local invoke HelloQueueProcessor \
--event events/sqs.json \
--env-vars env.json
Pipeline creation can be found under the pipeline/cdk folder.
This is an overly complicated hello world function developed on purpose to demo different Lambda integrations. In this case, an HTTP GET request to /hello will invoke a lambda function that sends a hello world message to an SQS queue, for which another lambda function processes the message asynchronously and stores it on a DynamoDB table.
There is a Lambda function that generates the data for this dashboard: https://www.awsdingler.com/kube. It gets triggered every 5 minutes by CloudWatch Events and it pings the Auto Scaling Group of the k8s worker nodes to get information about them and generate the data needed for the dashboard which is written to S3 in a results.json file. The ReactJS app pulls this json file and renders the dashboard.
