I'm having trouble finding the kernel options that Google's Container Optimized OS is built with. I tried looking at the usual locations like boot/config-* and /proc/config.gz, but didn't find anything. I searched the source code and didn't find anything either, but I'm probably just searching wrong.
The specific option I'm curious about is CONFIG_CFS_BANDWIDTH and whether it is enabled or not. Thanks!
You can get it via running zcat /proc/config.gz in a Container-optimized OS VM.
The kernel config is generated from the source here. However, note that the source kernel config are changed during the OS image building process. So they are not 100% the same.
