Not exactly the same, but you can run CI on aarch64 Linux with Drone:

Testing on ARM with Drone CI

Drone CI is a free and open-source continuous integration platform and allows running tests for Julia packages on ARM architecture. You can install a local instance of Drone or use Drone Cloud at https://cloud.drone.io/ Documentation of Drone is at https://docs.drone.io/. The .drone.yml script to add to the top-directory of your repository to run tests looks like the following: --- kind: pipeline name: linux - arm - Julia 1.0 platform: os: linux arch: arm steps: - name: build image: …

or more recent setup:

Testing Julia packages on x86_64 Alpine Linux with Drone CI

Alpine Linux is a lightweight Linux distributions, the base installation can be as little as 5-6 MiB. It’s different from most common distributions in that it’s based on the musl C library. There have already been a few official binaries of Julia for the musl C library (and so for Alpine Linux), but v1.6-rc2 is the first release where JLL packages, widely common in the ecosystem, will work properly with musl. It’s now a good time to start testing some packages, especially those calling into b…

Of course you aren’t going to catch any bugs specific to aarch64-apple-darwin, but that’s a good starting point.

For example I’m not using Drone in Measurements.jl but doing so would have caught Don't run `ccall` test on platforms that don't allow it by giordano · Pull Request #105 · JuliaPhysics/Measurements.jl · GitHub much earlier and this makes tests pass on aarch64-apple-darwin as well.
