  1. Backup CoreOS's data volumes

    Yaron made a great Docker image for creating backups using Duplicity. It's designed to make backups of host directories, but what I wanted is to backup other container's volumes. You can do this with this CoreOS unit file: [Unit] Description=Backup After=docker.service Requires=docker.service [Service] User=core…

  2. Copy data from one data volume to another

    Recently I've played around with Docker and CoreOS I made some mistakes in the beginning. When I discovered that my data volume is based on the same image as the container which is supposed to use it (therefore wasting disk space) I wanted to move my data from the old…

  6. Running Django on Arduino Yún

    Arduino Yún is awesome device for many reasons but one is my favorite: it's running small Linux with Python. And when I hear Python, I think Django. You can make simple webserver in C and ATmega32u4 but it won't be easy. There are two problems with Yún and Django: Even…
