  • Kubernetes volume-mounts with subPath and inotify. Bah humbug

    Kubernetes volume-mounts with subPath and inotify. Bah humbug

    So. I’ve been working on this tool ‘fluent-bit‘. You know the drill. Compile, curse, change, pull-request, repeat. And one of the features I added was to auto-watch its config file and restart on change.
