The big news out of Dockercon this year was the the Docker 1.12 update, providing an integrated swarm-mode container orchestration system directly into Docker. As a 
somewhat cautious person when it comes to running new stuff in production, I always wait for the .x.y update (in this case a .1) before running new stuff on systems I really care about.
Aside from a solid number of bug fixes that actually make swarm-mode very stable, there is a big update in the 1.2.1 update with an official ARM update that brings an easy installation to Raspberry Pi devices.
The git pull to look at for this is 24815“Adding support in install.sh to install the Docker Engine on a standard Raspberry Pi running a raspbian/jessie OS,” developer Dieter Reuter wrote.
In a message to me Reuter provided some additional color:
With the new Docker 1.12.1 release we’ve now reached a major milestone because you can now install Docker with a single command on every ever built Raspberry Pi, more than 8 million devices out in the world! Because with 1.12.1 there is the first ARM Debian package official available from Docker to install it on a standard Raspbian/Jessie OS. The only thing you need is, to login into a Raspberry Pi which is connected to the internet and type “curl -sSL get.docker.com | sh” – yeah, it’s just so easy right now!
We also just released our own new HypriotOS 1.0.0 for the Raspberry Pi a few hours ago – it’s way smaller than before and it already includes the Docker 1.12.1 official build for ARM.
So what are you waiting for? I know what I’m doing this weekend…
