@galvesribeiro I assume the machine you are building on is a linux base VM on Azure? I think you are missing `binfmt_misc` set up as mentioned here [Creating custom base images](https://forums.balena.io/t/creating-custom-base-images/1641/2) . You also might want to have a read through the original blog post for this feature here: [https://www.balena.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/](https://www.balena.io/blog/building-arm-containers-on-any-x86-machine-even-dockerhub/)
