Getting Started with VS Code

Run the app locally with minikube

1. To run your application, click on the Cloud Code status bar and select ‘Run on Kubernetes’.
   

2. Select ‘Run locally using minikube’ when prompted. Cloud Code runs your app in a local minikube cluster.
   

3. View the build progress in the OUTPUT window. Once the build has finished, click on the URL in the OUTPUT window to view your live application.
   

4. To stop the application, click the stop icon on the Debug Toolbar.

Getting Started with IntelliJ

Run the app locally with minikube

Edit run configuration

1. Click the configuration dropdown in the top taskbar and then click Edit Configurations.

   The Develop on Kubernetes configuration watches for changes, then uses skaffold to rebuild and rerun your app. You can customize your deployment by making changes to this run configuration or by creating a new Cloud Code: Kubernetes run configuration.

2. Under Run > Deployment, select 'Deploy locally to a minikube cluster'.

3. Click OK to save your configuration.

Run the app on minikube

1. Select Develop on Kubernetes from the configuration dropdown and click the run icon. Cloud Code runs your app in a local minikube cluster.
   

2. View the build process in the output window. When the deployment is successful, you're notified that new service URLs are available. Click the Service URLs tab to view the URL(s), then click the URL link to open your browser with your running application.
   

3. To stop the application, click the stop icon next to the configuration dropdown.
