AWS Lambda Kotlin Spring boot2 Demo

This demo referred https://github.com/awslabs/aws-serverless-java-container/tree/main/samples/springboot2/pet-store

Pre-requisites

  • AWS CLI
  • SAM CLI
  • Gradle or Maven

Deployment

In a shell, navigate to the sample's folder and use the SAM CLI to build a deployable package

$ sam build

This command compiles the application and prepares a deployment package in the .aws-sam sub-directory.

To deploy the application in your AWS account, you can use the SAM CLI's guided deployment process and follow the instructions on the screen

$ sam deploy --guided

Configuring SAM deploy
======================

        Looking for config file [samconfig.toml] :  Not found

        Setting default arguments for 'sam deploy'
        =========================================
        Stack Name [sam-app]: spring-boot2-demo-api
        AWS Region [ap-northeast-2]: 
        #Shows you resources changes to be deployed and require a 'Y' to initiate deploy
        Confirm changes before deploy [y/N]: y
        #SAM needs permission to be able to create roles to connect to the resources in your template
        Allow SAM CLI IAM role creation [Y/n]: 
        #Preserves the state of previously provisioned resources when an operation fails
        Disable rollback [y/N]: 
        DemoFunction may not have authorization defined, Is this okay? [y/N]: y
        Save arguments to configuration file [Y/n]: 
        SAM configuration file [samconfig.toml]: 
        SAM configuration environment [default]:
...
...
...
Deploy this changeset? [y/N]: y
...
...
...

Once the deployment is completed, the SAM CLI will print out the stack's outputs, including the new application URL. You can use curl or a web browser to make a call to the URL
