Wait, can someone tell me where to download this doesn't-eat-memory-like-crazy version of Chrome? Activity Monitor is showing me 2GB of Chrome processes right now and that's even with The Great Suspender having paused almost all my tabs.
The blog post is somewhat old[1] and not in sync with the version that is in Git[2], you might find a way to do this without Docker (I was using an old version of Docker and kernel that couldn't get it to work. But I need the old version of Docker for reasons.)
Chrome will aggressively consume any memory you give it (up to a point?) to "make your browsing experience better" somehow. You're not wrong. But there is modern technology that can make it better. If you have a fast SSD, then Chrome can still use Swap to make your experience better. The later version in the Dockerfile linked on Git also leverages swapaccount with the seccomp setting.
This may be one great use of Docker for people that wouldn't yet have been convinced to use Docker for any serious reason.

But won't you run into issues with child processes, of which Chrome tends to spawn a zillion? (I'm reading that each one gets its own limit under ulimit...)
And potentially get your browser killed when it hits the limit? I haven't tested this and I don't really know how ulimit works, but I think it's a less effective solution than the cgroups for at least one reason.
Or something pretty close to it.
