AWS CodeStar – Spring Boot Microservices
AWS CodeStar is a managed service from AWS that lets us quickly develop, build & deploy various applications across development languages, such as Java, Javascript, PHP, Ruby & Python.
We begin at the CodeStar home page at https://console.aws.amazon.com/codestar/home. Create a New Project and choose the Java Spring Lambda Web Service template:
Enter project name and ID and click Next:
Review project details and create project:
Select AWS Cloud9 as our code editor and click Next:
Select your preferred instance type and click Next:
We now arrive at our Project Dashboard. Wait for the Cloud9 environment to finish creating. Once that’s done, we need a way to try out our brand new microservice.
Add the App Endpoints tile to the Dashboard:
Open the App Endpoint in a new tab to see the output:
{
"Output": "Hello World!"
}Let’s try changing this! To get to our code, switch to the IDE tab & click Open IDE:
In the IDE, open HelloWorldHandler.java and change ‘Hello World!’ to ‘Hello World 2!’
Do the same in HelloWorldHandlerTest.java:
Commit & Push these changes:
Wait a few minutes for the automated Build & Deployment to finish. Now reopen the App Endpoint to see the change we made:
{
"Output":"Hello World 2!"
}
This was a simple example demonstrating the power of CodeStar. The code can be further elaborated to create full-fledged microservices!
