The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
H: preserves hard-links
A: preserves ACLs

Установка дистрибутива на SD

Raspberry PI SD Installer OS X — простой консольный скрипт для записи любых .img или .iso образов на SD флешки. Использование на OSX или Linux:

sudo ./install ~/Downloads/raspbian.img

Нахождение Raspberry Pi в сети

Подключили ethernet кабель, вставили флешку с Raspbian и запустили, но нет лишнего HDMI монитора и клавиатуры? Выход есть и это — Adafruit Raspberry Pi Finder. Использование на OSX или Linux:

1) Создаем юзера под которым будет работать приложение, задаем пароль и переключаемся на него:

useradd -s /bin/bash <имя_пользователя>
passwd <имя_пользователя>
su <имя_пользователя>

2) Генерируем новый ключ для деплоя

ssh-keygen -t rsa -C "<имя_пользователя>@<домен_сервиса>"

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm
