Deploying Spring Boot on IBM Cloud

To deploy a Spring Boot application on IBM Cloud, follow these steps:

  1. Sign up for an IBM Cloud account or use an existing one.
  1. Create a Cloud Foundry application on IBM Cloud and configure it for your Spring Boot deployment.
  1. Build a deployable artifact of your Spring Boot application (e.g., a JAR file).
  1. Use the IBM Cloud CLI or platform-specific tools to push your application to IBM Cloud.
  1. Configure authentication and access control settings as needed.

Sample Code for Spring Boot on IBM Cloud

Here's an example of a simple Spring Boot application that can be deployed on IBM Cloud:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@SpringBootApplication
public class SpringBootApp {
    public static void main(String[] args) {
        SpringApplication.run(SpringBootApp.class, args);
    }
}
@RestController
class HelloController {
    @GetMapping("/hello")
    public String hello() {
        return "Hello, IBM Cloud!";
    }
}
