Try running arm32 test-commit jobs in containers on aarch64 hosts #2775
Comments
We had previously discussed adding some raspberry pi4 systems into the jenkins farm, but that seemed to go stale. This would probably provide a more stable, and faster, option at zero additional cost and hopefully lower maintenance overhead. |
Initial testing with a copy of the node-test-commit-linuxone job:
On the basis of this, I'm going to propose adding this into the main group of jobs that run under node-test-commit and run it alongside node-test-commit-arm-fanned for a while to see how it works out. For comparison with the above figures, node-test-binary-arm-12+ has been taking over an hour for the most recent runs (and always over half an hour) so there are significant performance avantages to be had here. This would also remove the use of a cross-compiler for this platform if we wished to do so. Questions I see with the general approach:

Great to hear it seems to be working. Would be great to be able to use docker images versus physical machines. |
We used to have some alternative armv7 machines in node-test-commit-arm, but ran into technical and maintenance difficulties and pulled the plug. So it'd be nice to have them back even if just to increase the diversity of armv7 testing. Having the Pis in the cluster though gives us some confidence of running on actual armv7 hardware (particularly some that that hobbyists are using Node.js with). There might be a point in the future where we want to entirely retire the Pi cluster, but as long as we can keep it chugging along and not holding things up too badly then it would be nice to keep it in the mix. Sadly that future date creeps closer as the test suite expands! |
I've adjusted node-test-commit-arm to have another matrix option for ubuntu2004-armv7l and it looks to be running through ok for a Node17 build |
Changes now live. Closing. |
Unlike the old ThunderX systems, the new Altra machines which we recently set up are capable of running 32-bit ARM code, so can run our armv7l releases on the hardware.
Since we are already using multiple docker containers on those systems, we can also deploy armv7l containers running the distribution of our choice, and try running a non-fanned test job on those systems in an expedient manner.
