We have a base Debian image maintained by our Platform/Security team (compliance) that we build our Flask apps off. Other than them forgetting to push an ARM compatible image when they update we haven’t ran into issues, but I don’t know what went in behind the scenes to get the image working if anything.

I would say I’m the bridge between the infra/DevOps teams and our back end team of 12 people and as far as everyone else on the team is concerned it “just works”. Still waiting for the first big time it doesn’t

Thank you so much for replying! Could you go into some details?

So how do you bake your code in your base image ?

I'm referring to the developer experience here :

1. do you develop on x86 (mac, win, linux)?

2. Where do you build the arm docker images ? On your laptop - is it even possible.

3. Which build CI do you use to cross build arm?

1) most of the team is on MBP 16 inch models. I know there is one and may be two on 13 inch models.

2 and 3 I’ll answer to the “best of my knowledge” but on the professional level it’s something my team doesn’t handle (I do wish I knew more!). Features get merged to dev/stage/main and trigger blue-green rolling deploys based on whatever is configured. The deploy is handled through AWS CodeDeploy (not my choice, also not my teams jurisdiction) which handles ticket validation/testing/deploying to whatever k8s cluster/manual deployment rollover if needed.

I believe you can build ARM images from Docker, or at least I have a vague recollection of doing so for a Raspberry Pi, on a normal x86 machine

this is super interesting. it stands to reason that CodeDeploy would support docker crossbuild.

In my team we mandate testing docker images on local dev machines before rolling to production, so i was wondering how the cross-compiles, etc would work . But this is helpful. thanks!
