Snappy ThingsJan 20, 2015
A while back, Snappy was introduced and it was great, while that was happening we were already working on the next great thing, Snappy for devices, or as everyone calls it, things.
Today that was finally announced. It’s been lots of fun working on this. Enablement aside, we also created a very minimal webdm, it is a Web Device Management snap framework provided in the store which can be easily installed on existing devices by calling
sudo snappy install webdm
On networks where it is allowed, it can be accessed by going to http://webdm.local:4200. Here’s a quick demo of it running on a BeagleBone Black
So to get this going, all you need is to follow what is mentioned in the main site and pop that sdcard into the device
wget http://cdimage.ubuntu.com/ubuntu-core/preview/ubuntu-core-WEBDM-alpha-02_armhf-bbb.img.xz unxz ubuntu-core-WEBDM-alpha-02_armhf-bbb.img.xz dd if=ubuntu-core-WEBDM-alpha-02_armhf-bbb.img of=/dev/sdXXX bs=32M
The alternative way is to use ubuntu-device-flash to create such image, you can get it easily for Ubuntu by adding our tools ppa
sudo add-apt-repository ppa:snappy-dev/beta sudo apt update sudo apt install snappy-tools
And then move on to building your image, this is what I do:
ubuntu-device-flash --verbose core --channel ubuntu-core/devel-proposed --output snappy-core.img --size 10 --developer-mode --install webdm_0.1_multi.snap --install beagleboneblack.element14_1.0_all.snap
The install option is basically an option to install
provisioning; you may notice this weird one
beagleboneblack.element14_1.0_all.snap, that is an oem snap and in summary,
it’s similar to the customization framework in Ubuntu Touch, but different.
today it’s pretty minimal and allows to just set the branding text either as
can be seen on the video or at the login prompt, where you would see something
More on the
oem part later.
