We have been running oet.sandcats.io in Educloud since November 2015 and have 72 instructional designers, faculty, and technologists with 255 app instances (grains) to date.
Think of a ‘grain’ much like you would software containers and operating-system-level virtualization, but with unique features. As Sandstorm.io describes it:
The idea is simple: take your large web app and split it into small “services” running in separate containers. Services are separated by functionality: you might have an authentication service, a payment service, a search service, and so on.
Sandstorm takes a wildly different approach: It containerizes objects, where an object is primarily defined by data. We call each Sandstorm container a “grain”, because it is fine-grained.
I have been working quite a bit with the framework and working on packing opensource applications currently not available. I haven’t been writing about my work so I figured I’m overdue to start posting about how I’m using oet.sandcats.io and outlining my forays in packaging opensource applications for hosting at oet.sandcats.io.
For today’s post – how I mapped Dropbox-clone Davros (https://github.com/mnutt/davros) to a subdomain of networkeffects.ca
- Get your Davros grain open.
- Navigate to the [Publishing] area.
- Fill in your desired sub/domain
- Make your CNAME and TXT entries in your DNS Zone Editor (my CPanel views below)
- Put an empty index.html file in your Davros grain.
- Give your DNS entries some time to take hold. (mine took around 20 minutes)
- Upload a file to your Davros grain.
- Put your mapped sub/domain in front of the filename you just uploaded.
- Shared! http://files.networkeffects.ca/rick-gif.gif
Now, for any file you put in this grain, you can easily share it on the web by placing the sub/domain on the front of the filename.
Davros at oet.sandcats.io has a 2GB file upload limit. By navigating to the [Clients] area of the app you can generate values that allow you to synchronize this app to a ownCloud client desktop client. Select one or more directories on your local machine and always have access to your latest files wherever you are.
