docker container linux-tools-generic package
My goal is to use perf to run performance tests on some Docker images. By default, the images I'm using don't come with perf. As such, I tried
apt-get update
apt-get install linux-tools-generic
to get perf, but I got
E: Unable to locate package linux-tools-generic
I asked on SO, and was told that my sources.list might not be set up properly, and was also sent here because my confusion better pertains to SF.
Any advice on how I can get/run perf inside various Docker containers?

apt-get -qq update && apt-get -qq install linux-tools-generic
не сработало, у меня есть другое решение.Я сделал
apt-get update
apt-get install linux-tools
, который, как я понял, дал мне perf_4.9. Позже будет мягкая ссылка, perf теперь работает внутри контейнера докеров. Это не зависит от ядра, но работает для того, что мне нужно (пока).
