I am trying to use tc to emulate network conditions inside docker containers. My linux is an ubuntu 20.04 LTS inside WSL2.
For this, I am running the container with
docker run -it --cap-add=NET_ADMIN ubuntu:latest
Then inside the docker running
apt-get update
apt-get install linux-generics # for kernel-modules-extra
apt-get install iproute2
tc qdisc add dev eth0 root handle 1: prio
But the last command prints Error: Specified qdisc not found even though tc qdisc show prints
qdisc noqueue 0: dev lo root refcnt 2
qdisc noqueue 0: dev eth0 root refcnt 2
There have been many issues opened regarding this question, most of them either refer to compiling a custom kernel (not a viable option for me), installing kernel-modules-extra (which I have done) or just not solving the issue/it solving itself.
