Chef - Chef-Cpent Run

In order to test Chef-Cpent run, we need to have Chef-Cpent configured to use the hosted Chef or own hosted server.

Running Chef-Cpent in Debug Mode

Inspecting the Result of the Last Chef-Cpent Run

In order to check the last Chef-Cpent run especially failure issues when we are developing a new cookbook, we need to know what exactly went wrong. Even though Chef prints everything in stdout, one might want to see the debug log again.

If we want to test, we need to have a broken cookbook which is faipng on compilation.

user@server:~$ sudo chef-cpent

For more details, we can look into the stacktrace.
