Exercise 16 - Useful CF Commands

In this exercise, you will go through a basic set of CF commands that are useful in the context of SAP Fiori development.

Exercise 16.0 - Preparations

After completing these steps, you will know which CF commands are available, what they do and try out a few of the available commands.

  1. Open a new terminal using Terminal | New Terminal or *[CTRL] + ~* keyboard shortcut.



  2. Double-click the terminal tab to maximize it.



Exercise 16.1 - cf help

  1. Run cf help to get the list of all available commands.



  2. To show a list of all available commands with a single line description for each command run cf help -a.



    Tip 1: Run the clear command to cealr the terminal

    Tip 2: Instead of executing cf help -a, run *cf help -a | more. the commands will be printed to the terminal one screen at a time. To see the next line press the [ENTER] button. To see the next screen press the [SPACE] button.

  3. Digging one level deeper, getting help for a spcific command, run cf help [COMMAND] e.g. cf help login.



Exercise 16.2 - cf logout

  1. In a previous exercise we saw how to log in to CF using the command palette. In the last step we saw how to log in to CF using the command line. To log out from CF use cf logout. You'll get indication of successful log out both in the terminal as well as in the status bar at the bottom left of the screen.



Exercise 16.3 - cf html5-list

  1. To get the list of SAP Fiori / SAPUI5 deployed to the CF space you're logged in to, run cf html5-list.



    You need to be logged in to your CF space to perform this command.

Exercise 16.4 - cf mtas

cf mtas lists all deployed mluti-target apps. In the context of this exercise, it provides the mta id that is needed to undeploy a multi-target app.

Exercise 16.5 - cf undeploy

Usually you should start with the deploy finctionality. However, since the appis laready deployed, you'll start with the undeploy functionality.

  1. To undeploy a multi-target applications (MTA) deployed to the CF space you're logged in to, such as the app you've just deployed, run cf undeploy [mta id] --delete-services --delete-service-keys -f. The mta id of the app you've just deployed appear in the output of the command you performed in the previous step. Therefore, if you want to undeploy the app, run cf undeploy products-inventory --delete-services --delete-service-keys -f



    In the SCP Cockpit, in the CF space, you can see that the app and all its bound sevice instances were removed.









Exercise 16.6 - cf deploy

  1. To deploy (or re-deploy) your MTA, run cf deploy MTA. For this demo the MTA resides within the mta_archives folder. Therefore, run cf deploy mta_archives/products-inventory-0.0.1.mtar.



    In the SCP Cockpit, in the CF space, you can see that the app was deployed and all its sevice instances were created and binded.





Exercise 16.7 - Run the App on CF

  1. You're welcome to test-run the app deployed on CF as you did in a previous exercise.
