In this step, you will deploy serverless API, utilising AWS resourcesLambda Functions and API Gateway. To do so, you will use AWS SAM CLI to package, and deploy SAM CloudFormation template.
Before doing anything else, make sure you clone the repo into Cloud9 workspace
git clone https://github.com/toshke/aws-waf-demo-workshop.git
Important Set your region to us-east-2, or region where your Cloud9
runs. You can do so by exporting AWS_DEFAULT_REGION variable, e.g.
export AWS_DEFAULT_REGION=us-east-2
For the demo, I've used melbournecloudtoolsmeetups.$timestamp for bucket name, but you can really use any bucket.
export BUCKET_NAME=melbournecloudtoolsmeetup.`date +%s`
aws s3 mb s3://${BUCKET_NAME}
Remember your S3 bucket
As an AWS SAM exercise, package the template first - this will
replace all local references to application code to hardcoded ones, pointing
to code that has been uploaded to S3 bucket created in previous step.
For this you will use sam package command
$ cd step1
$ sam package --template-file=template.yaml --s3-bucket=$BUCKET_NAME --output-template=template.processed.yaml
You should see output like following
Successfully packaged artifacts and wrote output template to file template.processed.yaml.
Execute the following command to deploy the packaged template
aws cloudformation deploy --template-file /Users/nikolatosic/Development/projects/github/aws-waf-demo-workshop/step1/template.processed.yaml --stack-name <YOUR STACK NAME>
In this step you deploy serverless API
aws cloudformation deploy --template-file template.processed.yaml --stack-name CloudToolsMeetup-DEC19-API --capabilities CAPABILITY_IAM
In order to feed bees with machineguns an endpoint url in next step, you will need to read the endpoint form stack outputs first. Use command below to read your API Endpoint
ENDPOINT_URL=$(aws cloudformation describe-stacks --stack-name CloudToolsMeetup-DEC19-API --query 'Stacks[0].Outputs[0].OutputValue' --out text)
echo $ENDPOINT_URL
sudo yum -y install jq && curl -s $ENDPOINT_URL
You should see output as following, retrieving your basic API resource
$ ENDPOINT_URL=$(aws cloudformation describe-stacks --stack-name CloudToolsMeetup-DEC19-API --query 'Stacks[0].Outputs[0].OutputValue' --out text)
$ sudo yum -y install jq && curl -s $ENDPOINT_URL

Nothing to do

Congratulations, you have successfully deployed serverless API in AWS and Completed step1 of this workshop.
