hello-world

This repo provides a simple Hello World sample project for Spring Boot.

It can be deployed as a standalone web app, as a Cloud Foundy app or as a TAP workload, depending on the deployment option choosen when generating the project.

Deployment

Standalone app with embedded Tomcat server

You can build the project using Maven:

./mvnw clean package

To run the app using the embedded Tomcat server you can run this command:

./mvnw spring-boot:run

You can modify the default message "World" using an application property of app.message:

./mvnw package  
java -jar target/hello-world-0.0.1-SNAPSHOT.jar --app.message=Test

Deploying to TAP

If you make modifications to the source and push to your own Git repository, then you can update the spec.source.git information in the config/workload.yaml file.

You can deploy and use the config/workload.yaml file to set the initial message:

tanzu apps workload apply -f config/workload.yaml

If you would like deploy the code from tyour local working directory you can use the following command:

tanzu apps workload create hello-world -f config/workload.yaml \
  --local-path . \
  --source-image <REPOSITORY-PREFIX>/hello-world-source \
  --type web

Accessing the app deployed to your cluster

Determine the URL to use for the accessing the app by running:

tanzu apps workload get hello-world

To access the deployed app use the URL shown under "Workload Knative Services".

Then, use curl or some other utility to access the URL:

curl <URL>

This depends on the TAP installation having DNS configured for the Knative ingress.
