Creating an application with a Spring Boot code sample

Note: The Spring Boot code sample uses the 8081 HTTP port.

Before you begin creating an application with this devfile code sample, it's helpful to understand the relationship between the devfile and Dockerfile and how they contribute to your build. You can find these files at the following URLs:

• Spring Boot devfile.yaml
• Spring Boot Dockerfile

1. The devfile.yaml file has an image-build component that points to your Dockerfile.
2. The docker/Dockerfile contains the instructions you need to build the code sample as a container image.
3. The devfile.yaml kubernetes-deploy component points to a deploy.yaml file that contains instructions for deploying the built container image.
4. The devfile.yaml deploy command completes the outerloop deployment phase by pointing to the image-build and kubernetes-deploy components to create your application.
