command 'tc' failed in /TargetContainer

[steppangit]

Running pumba directyl in ubuntu 20.04.

• tc is installed via iproute2 inside the TargetContainer.
• which is installed inside TargetContainer.
• docker exec -it TargetContainer which tc shows correct path.
• User in TargetContainer is root
• tried --cap-add=ALL to TargetContainer, doesn't help
• sudo pumba doesn't help

Do you have any idea what I am missing?

#159 which has been closed without a solution seems to be a similar issue.
Unfortunately I can't find any solutions.
TC does not work even with tc-image and commands from your own readme.
Could this be related to the host docker api running on windows?

[steppangit]

I found out that this is purely a windows issue.
WSL 2 currently does not support tc with sch_netem.
If you really need to get this going with windows you need to compile and provide a custom kernel for WSL 2.
Works right away with Linux as a host.
