GH Action Build MacOS Fails with Docker Error

[wesleyboar]

Overview

Running "TACC Docs Build" action with runs_on macos-latest fails with error:

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

The rabbit hole of research to a solution seems to never end, but might require a different action in uses.

Status

Fixed:

• fix: GH-23 support macos docker users #58

Workaround

If you need to use on macOS, then build on your macOS locally.

Important

Builds we host online are currently Ubuntu (build, commit), cuz our servers use Ubuntu.

I followed the rabbit hole of References further.

The bug was fix for macOS 13, but the fix was removed for macOS 14.

See alternative, crazy-max/ghaction-setup-docker.

[wesleyboar]

Well, bother. It seems we must:

• Hope GitHub restores support for macOS 13 or macOS 14.
• Hope crazy-max/ghaction-setup-docker begins to work on macOS ARM.
• Wait for Apple to release macOS 15.
• 🆕 add arm64 to the build

[wesleyboar]

All of my investigation seems irrelevant. The fix was setting arm64 as a platform for the build int he workflow:
