TurnKey Linux Virtual Appliance Library

Comparing Debian vs Alpine for container & Docker apps

Background: For TurnKey 15 (codenamed TKLX) we're evaluating a change of architecture from the current generation of monolithic systems to systems as collections of container based micro-services. Essentially the service container replaces the package as the highest level system abstraction.

There are several layers to the new architecture, but the first step is to figure out the best way to create the service containers. Alon has been quietly working on this for the last couple of months and managed to slim down Debian to 12MB compressed for the base image:

v14.1 Release - Bugfixes, Maintenance and More

About seven months after the release of v14.0 we are proud to announce the updated v14.1 release.

All of the v14.1 appliances are available for immediate launch in the cloud via the Hub. Amazon MarketPlace builds are on the way too although no ETA at present. All the other builds (e.g. ISO, OVA, Xen, etc.) can be downloaded from their respective appliance pages (eg. LAMP, WordPress Node.js etc). Alternatively the entire library can be downloaded via one of our mirrors.

v14.0 stable release - Massive Community Effort!

Drum roll please... May I proudly introduce: The TurnKey Linux v14.0 release!

A long time coming...

Wow is it mid September already!? What has happened to the year?!

Marching towards v14.0 RC2

Update: v14.0 stable is available in all build types: OVA & VMDK, Proxmox, OpenNode & Docker (Proxmox build is somewhat generic LXC/OpenVZ container) and Xen & OpenStack.

As anyone who has been paying attention would realise; v14.0RC1 has been out for over a month now.

TurnKey v14.0 RC1 is LIVE! (aka we need YOU!)

Update: v14.0 stable is available in all build types: OVA & VMDK, Proxmox, OpenNode & Docker (Proxmox build is somewhat generic LXC/OpenVZ container) and Xen & OpenStack.

It is with great pleasure that I announce the release of Core v14.0RC1 and TKLDev v14.0RC1! But first a little history and context...

How to upgrade a Debian package to a newer upstream version

Duplicity issued a new stable version with a few bugfixes. I didn't want to wait for the Debian sid package to update so I updated it myself.

This was very simple as the Debian duplicity package uses dpatch to manage all the patches to the original source code. The patches go to debian/patches.

When the package is built debian/rules applies these patches:

dpatch apply-all

Creating a new dpatch is also automated::

What if all Debian/Ubuntu based dists used TKLDev?

Imagine if every Debian distribution in the world in the world was using TurnKey's build chain and collaborating with us on its development instead of limping along with various inefficient ad-hoc tools?

TurnKey currently doesn't get as many contributions back from the free software community as we'd like (our fault). I think there are two main reasons for that:

TurnKey 13 out, TKLBAM 1.4 now backup/restores any Linux system

This is really two separate announcements rolled into one:

  1. TurnKey 13 - codenamed "satisfaction guaranteed or your money back!"

    The new release celebrates 5 years since TurnKey's launch. It's based on the latest version of Debian (7.2) and includes 1400 ready-to-use images: 330GB worth of 100% open source, guru integrated, Linux system goodness in 7 build types that are optimized and pre-tested for nearly any deployment scenario: bare metal, virtual machines and hypervisors of all kinds, "headless" private and public cloud deployments, etc.

    New apps in this release include OpenVPN, Observium and Tendenci.

    We hope this new release reinforces the explosion in active 24x7 production deployments (37,521 servers worldwide) we've seen since the previous 12.1 release, which added 64-bit support and the ability to rebuild any system from scratch using TKLDev, our new self-contained build appliance (AKA "the mothership").

    To visualize active deployments world wide, I ran the archive.turnkeylinux.org access logs through GeoIPCity and overlaid the GPS coordinates on this Google map (view full screen):


  2. TKLBAM 1.4 - codenamed "give me liberty or give me death!"

    Frees TKLBAM from its shackles so it can now backup files, databases and package management state without requiring TurnKey Linux, a TurnKey Hub account or even a network connection. Having those will improve the usage experience, but the new release does its best with what you give it.

    I've created a convenience script to help you install it in a few seconds on any Debian or Ubuntu derived system:

    wget -O - -q $URL | PACKAGE=tklbam /bin/bash

    There's nothing preventing TKLBAM from working on non Debian/Ubuntu Linux systems as well, you just need to to install from source and disable APT integration with the --skip-packages option.

    Other highlights: support for PostgreSQL, MySQL views & triggers, and a major usability rehaul designed to make it easier to understand and control how everything works. Magic can be scary in a backup tool.

    Here's a TurnKey Hub screenshot I took testing TKLBAM on various versions of Ubuntu:

TurnKey 12.1 64-bit maintenance release built with new tkldev build appliance

TurnKey 12.1 is out and it's the first 64-bit maintenance release to be built with tkldev - TurnKey's shiny new open appliance build system in a box.

With 64-bit support out the door, we've also pushed out a round of updates to the Hub so that users can finally deploy TurnKey on all instance sizes.

TurnKey Core 13.0 RC (i386, amd64, wheezy)

Drumroll please... I'm thrilled to make not one, but two announcements!
