Please see the replacement repositories available for Node.js, Go, Java Liberty, Java Spring, Python Flask, Python Django, and Swift.
This repository will not be updated. The repository will be kept available in read-only mode.
We have similar applications available for Go, Java Liberty, Swift, Python Flask, and Node.
In this sample application, you will create a basic Java web application using Spring. Thisprovides a starting point for creating applications running on Spring. It contains no default application code, but comes with standard best practices, including a health check and application metric monitoring.
You can deploy this application to IBM Cloud or build it locally by cloning this repo first. Once your app is live, you can access the /health endpoint to quickly build out your cloud native application.
Use the button above to deploy this same application to IBM Cloud. This option will create a deployment pipeline, complete with a hosted Git lab project and devops toolchain. You will have the option of deploying to either CloudFoundry or a Kubernetes cluster. IBM Cloud DevOps services provides toolchains as a set of tool integrations that support development, deployment, and operations tasks inside IBM Cloud.
To get started building this application locally, you can either run the application natively or use the IBM Cloud Developer Tools for containerization and easy deployment to IBM Cloud.
- Maven
- Java 8: Any compliant JVM should work.
- Java 8 JDK from Oracle
- Java 8 JDK from IBM (AIX, Linux, z/OS, IBM i), or Download a Liberty server package that contains the IBM JDK (Windows, Linux)
To build and run an application:
mvn installjava -jar ./target/springstarter-1.0-SNAPSHOT.jar
To run an application in Docker use the Docker file called Dockerfile. If you do not want to install Maven locally you can use Dockerfile-tools to build a container with Maven installed.
Install IBM Cloud Developer Tools on your machine by using the following installation command: curl -sL https://ibm.biz/idt-installer | bash.
Your application will be compiled with Docker containers. To compile and run your app, run:
ibmcloud dev build
ibmcloud dev runThis will launch your application locally. When you are ready to deploy to IBM Cloud on CloudFoundry or Kubernetes, run one of the commands below:
ibmcloud dev deploy -t buildpack
ibmcloud dev deploy -t containerYou can build and debug your app locally with:
ibmcloud dev build --debug
ibmcloud dev debug- Learn more about augmenting your Java applications on IBM Cloud with the Java Programming Guide.
