Prerequisites:

• CDK CLI version : 1.95.0 >=
• Maven and NPM package manager

Checklist

• Use your own AWS CLI Credentials
• Create Secret Manager with Github token
• Add Environment variables

Workflow

Install project specific dependencies.

npm install @types/node
npm install 
npm run build

cdk bootstrap --show-template > bootstrap-template.yaml
cdk bootstrap aws://$CDK_DEFAULT_ACCOUNT/$CDK_DEFAULT_REGION --cloudformation-execution-policies arn:aws:iam::aws:policy/AdministratorAccess --template bootstrap-template.yaml

You can check diff of changes, synthesize your application stack and deploy.

cdk synth
cdk deploy
