A bit of #devops ranting. I used GitHub Actions to generate public #Docker images and upload them to registries like Docker Hub. However, for a couple of weeks, GitHub-hosted runners (using Ubuntu 24.04) stopped building #arm64 images . To my surprise, there is no major issue with locally hosted runners besides their resource consumption inconvenience. Since I keep a simple CI/CD (trigger and crons) I was wondering whether it might be worth using act ( https://github.com/nektos/act ) instead and inspecting resulting logs with CLI tools such lnav ( https://lnav.org/ ). Of course, I could always revert to Makefile or Shell scripts .
