Hey resin.
I have received the ‘builder unavailable’ notice the last few days and, perhaps incorrectly, assume it’s because resin.io have only a set amount of resources available for building.
I was wondering if it’s possible to use external agents of my own to build then deploy to my devices through resin.io? I am a small hobbyist with only a couple of devices.
Hi,
We are aware of the issue and working on it. It seems to happen more frequently when building applications that contain large binary files or building multiple times in quick succession (perhaps without letting the previous build complete if the user presses ctrl+C).
Does your project contain any large binary files?
Have you been building multiple times in quick succession or cancelling builds with ctrl+C?
You could build your code locally (if needed) and then use resin sync to sync with your device, skipping out the builder completely.
I hope this helps,
Joe
It started to fail on the first build of the day but it did clear.
The other night though I did have a few quick commits, back to back so I thought that would have been the case then.
I’ll adjust my testing process to give some delay between docker builds and trial the sync process 
Thanks for following up so quickly
