Correct and it won't work and install by default in our classroom environment. The systems don't technically meet the minimum requirements and it does fail the installation. We provide some "switches" to ignore the system check for memory and allowing the installer to run.

Specifically, when running the setup.sh script, you must use the 

-e ignore_preflight_errors=true

option along with that command.  This will tell it to "ignore" the hardware requirements - specifically the memory. Note that this isn't recommended for production systems and should only be used for the course. It should have been highlighted in the student guide with these instructions as well as an explanation of why we are doing that.

Thank you for responding Travis! In hindsight, I realized that I had an incorrect value in the inventory file. I had to tear down my environment and re-build it. Everything is working now. Yay! My mistake.

Have a great rest of the week!

Hi Travis,

I am also facing the same issue when running the setup.sh script with -e ignore_preflight_errors=true.

Is there any other way around this?

Thanks!

There is no way around the issue other than to use the option. Ensure that you are running as the root user, you are in the correct directory with the setup.sh script and the inventory file has been configured correctly. The ignore_preflight_errors=true skips the checks on the systems and allows you to install AAP Controller (even though it doesn't meet hardware requirements for memory/CPU/etc.).
