Create a dedicated ZFS docker pool with deduplication disabled in case of dedup enabled on your system:

zfs create -o mountpoint=/var/lib/docker -o dedup=off rpool/docker

Sometimes, you don't want ZFS for docker storage. ZFS can be sadly quite painful with Docker in Docker and similar scenarios. It might be best to avoid the problem by creating a volume in your ZFS pool, formatting that volume to ext4, and having docker use "overlay2" on top of that, instead of "zfs".

zfs create -s -V 30G rpool/docker

mkfs.ext4 /dev/zvol/rpool/docker

A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".
