Why the downvote? Simple tools always work well. If you want process isolation on Linux, LXC + rsync might as well be the simplest route.

Docker is based on LXC containers. It bundles it's own management layer that replaces the "rsync" solution you propose.

The point of Docker is the standardized container/management interface. Of course you can write your own, but then it's not too standardized is it?

What you describe is standardizing complexity where a simple solution is available. Naturally, when feasible, I prefer keeping things simple and straightforward enough that standardization is unnecessary.

Standardization for the sake of standardization is not defensible.

Anything not pro-docker usually gets downvoted by shykes and his ring of cronies.

There's definitely hype behind Docker, but this is a ridiculous accusation.

People do crazy things for money.

You have rationalized away the people who disagree with you by making them into a conspiracy. I don't know about said ring of cronies, but I guarantee that many downvoters are not associated.

My claim seems validated. Just look at both of my comments in this thread; they've both been downvoted deep into the negatives.

My downvotes because the comments were disparaging and lacked proof. My only Docker affiliation is reading a bit about it lately. I had to search the page to see who shykes is.
