Provisioners

Provisioners use builtin and third-party software to install and configure the machine image after booting. Provisioners prepare the system for use, so common use cases for provisioners include:

• installing packages
• patching the kernel
• creating users
• downloading application code

These are just a few examples, and the possibilities for provisioners are endless.
