I have two ‘apps’ that run on Rpi zero and Rpi3 respectively (nodes and hub)
The docker containers I use for both are multi stage - but the first container that both apps use is identical. I’ve tried building this locally and pushing to docker hub - but the emulation part seems wrong and it fails when deployed to the pi’s. The images build using resin work perfectly.
Is there a way for me to tag this first image such that I can use it as a base image across both projects? I thought maybe just because they were the same resin / docker would realise and pull from cache but I guess each project has a separate image cache.
