Deploy the Sample App: 

1. Download the app with git:
   git clone https://github.com/cloudfoundry-samples/cf-sample-app-spring.git
2. Navigate to the app directory: cd cf-sample-app-spring
3. Sign in to PWS: cf login -a https://api.run.pivotal.io
4. Push the app to PWS: cf push my_app

View the Logs: 

1. View a snapshot of recent logs: cf logs cf-spring --recent 
2. Stream live logs: cf logs cf-spring 

Adding a Service/Connect a Database:

1. List the available ElephantSQL plans: cf marketplace -s elephantsql
2. Create a service instance with the free plan: cf create-service elephantsql turtle cf-spring-db
3. Bind the newly created service to the app: cf bind-service cf-spring cf-spring-db
   NotE: Once a service is bound to an app, environment variables are stored that allow the app to connect to the service after a push, restage, or restart command.
4. Restart the app: cf restart cf-spring
5. Verify the new service is bound to the app: cf services 

Create/Delete user-provided service:

1. Create Eureka Server as eureka-service : cf cups eureka-service -p '{"uri":"https://eureka007.cfapps.io/"}'
2. Delete eureka-service : cf delete-service eureka-service

 Scale the App: 

1. Increase the number of app instances to two: cf scale cf-spring -i 2
2. Check the status of the app and verify there are two instances running: cf app cf-spring
   NotE: Scaling your app vertically changes the disk space limit or memory limit for each app instance.
3. Increase the memory limit for each app instance: cf scale cf-spring -m 1G
4. Increase the disk limit for each app instance: cf scale cf-spring -k 512M
