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

didn't work, I got a different solution to work for me. I'd done 

apt-get update
apt-get install linux-tools

Which I realized gave me perf_4.9. A softlink later, perf now works inside a docker container. It's not the kernel specific one, but it works for what I need (so far).
