Is it possible to use docker container for the bare metal project, want to generate ARM compatible firmware?

I am using nrf52 chipset, I just want to know did anyone tried to run docker container to create ARM image? I am thinking to use Docker container as CI.

For anyone who runs into this later like I did:
The question was "run docker container to CREATE arm image" and not "run docker container ON THE TARGET HARDWARE", so the answers below seem a bit off in my opinion.

Building the firmware in a docker container is possible and personally, I do not see good reasons to install anything locally, if docker is an option.

see e.g. https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/build-ncs-application-firmware-images-using-docker.
