This end-to-end vRealize Automation Cloud Assembly use case shows an example of creating infrastructure and deploying a WordPress site onto that infrastructure.
Look at the sequential setup to understand the process that brings a WordPress site to completion.
Remember that the values you see are only use case examples. You won't be able to use them letter-by-letter in your environment.
Think about where you would make your own substitutions, or extrapolate from the example values, in order to fit your own cloud infrastructure and deployment needs.
