Disabling Transparent Huge Pages on Splunk docker release

reallyliri — Wed, 27 Feb 2019 09:57:07 GMT

I recently learned, using SplunkAdmins app that I should disable Transparent Huge Pages on my Splunk Enterprise host.
However, I'm using the Splunk docker image, which I expect would include such a recommended configuration by default?
In any case, when trying to disable them, I'm getting an error that the file-system is readonly.
There seems to be a solution to that - namely making the file-system writeable by remounting it.
Do you think the Splunk docker image should be modified to disable THP? Should I use the blunt solution of remounting the FS?

You can (have to) disable THP in underlying VM with docker that runs your docker image. Any change in VM OS will propagate into running docker image guest host. Verified. Works.
