Running and building ARM Docker containers in x86

We already covered how Linux executes files and how to run ARM binaries “natively” in Linux in the last two posts. We ended up running a whole ARM root filesystem transparently in a chroot jail using QEMU user mode and binfmt_misc support. Now that we have that covered, nothing prevents us from applying that to …

Building Armbian images faster using Docker

The people at the Armbian team have been doing an impressive work at optimizing and generating Debian images for many ARM boards.

It is layered on top of my minidebian container, and I usually expand it further depending on the project. See this example. Features GCC 6 ccache for fast …

NextCloudPi, a ready to use NextCloud image for Raspberry Pi

IMPORTANT: The contents of this blog post are a detailed explanation of NextCloudPi. However, the main landing page of the project is now nextcloudpi.com and that is the place where information will be kept up to date. I would like to introduce NextCloudPi, ready to use Raspbian 9 image with the latest Nextcloud 13. NextCloudPi …
