Deploy Lambda + API app with serverless, codepipeline ci in AWS

Serverless Framework: Lambda + API in codebuild in AWS

Overview

CodePipeline will create 2 Lambda apps (javascript + python3) and get a domain url via Apigateway + route53, using serverless

I used this tuto.

Deploy

Requisit

• Optional: create a certificate for this API e.g.: *.api.demo.cloudlabs.link
• You can create a new serverless template with : serverless create --template aws-nodejs
• First create the IAM user with:

cd cloudformation
nano main.yml <-- edit with your needs
aws cloudformation create-stack --stack-name serverless-demo-hello-dev-cf --template-body file://main.yml
aws cloudformation update-stack --stack-name serverless-demo-hello-dev-cf --template-body file://main.yml <-- if already created

• You will get the value from the output.

Deploy manually

• Deploy with: sls deploy --stage develop --verbose
• Deploy to prod: sls deploy --stage master --verbose

To deploy to all component another environment, in DEV, change the stack-name user:

Test with your own URL and API key (you will find the key in aws console apigateway -> apikeys):

curl -H "x-api-key: CsYjYxhWiNaKho6Bqt9EW2UbQulgd5475H947qyb" https://kl4q7u9lg3.execute-api.eu-west-1.amazonaws.com/dev/hellojs/
{"message": "hello world"}%

Deploy via CI

• Edit ci with your needs: nano .gitlab-ci.yml
• Push file

Deploy/test locally

serverless offline
curl http://localhost:3000/dev/hellojs

Check values

aws cloudformation describe-stacks --stack-name gitlabpoc --region eu-west-1
--query 'Stacks[0].Outputs[?OutputKey==ServerlessApiKey].OutputValue'
--output text

Destroy all

• Destroy using the right region: aws cloudformation delete-stack --stack-name sam-demo-develop --region eu-west-1

Todo:

• Secure with APIkey
• Dev + Prod
• Cloudformation init
• Ci create + delete stack
