When running percona/percona-server:5.7 image and enable TokuDB it complained about transparent huge pages (THP) is enabled. However I have turned it off under: "Computer Configuration\Windows Settings\Security Settings\Local Policies\User Rights Assignment"

https://learn.microsoft.com/en-us/windows/security/threat-protection/security-policy-settings/lock-pages-in-memory

When I run the following line:

docker run --name ps -e MYSQL_ROOT_PASSWORD=root -e INIT_TOKUDB=yes  percona/percona-server:5.7

I get this error message:

Disabling transparent huge pages for the current session...
/usr/bin/ps-admin: line 708: /sys/kernel/mm/transparent_hugepage/defrag:  Read-only file system
/usr/bin/ps-admin: line 711: /sys/kernel/mm/transparent_hugepage/enabled: Read-only file system
ERROR: Failed to disable transparent huge pages for this session.

Any idea how to turn it off before starting the docker image?

I can see it is enabled in the:

bash-4.2$ cat /sys/kernel/mm/transparent_hugepage/enabled
always [madvise] never

Which docker engine are you using? Within Docker Desktop go to settings. Then under the general section it will show Use the WSL2 based engine. If this is checked then more than likely the issue is with using WSL2.

Additionally, look at your my.cnf file. If the cnf file has the thp-setting in it, mysql will try to write the setting that exists into those locations when it starts. If you comment out or remove that line in my.cnf, it should work fine.
