Thanks, @ricardozanini . The code looks good. But it is confusing that we use new-app to create a project and delete-project to delete a project. And maybe, we can use one command delete to delete both project and service, just like how kubectl and oc work. WDYT?

Hi @xiezhang7! Thanks for reviewing it. Yes, we'll change the new-app command to new-project:
#52

I'm just waiting for this to get merged to continue the work there.

We agreed in the https://issues.jboss.org/browse/KOGITO-248 to call delete-service and delete-project to perform those operations since service means something different in OCP. 😢
