You can populate the pce.yaml by running workloader pce-add or copy the following template (Make sure to create your own PCE service account API key and PCE info)
Note: Make sure you are root in that directory
To populate multi-line text file from shell, use printf
Quick test for workloader (if you have some workloads in idle to run the following to print in console the output via stdout)
./workloader compatibility -i --out stdoutExpected output should look like this (depends on your workloads for sure)
