I think a few lock files can be removed.

Did you try with the submit sub command (https://ss64.com/mac/launchctl.html):

     submit -l label [-p executable] [-o stdout-path] [-e stderr-path] --
              command [arg0] [arg1] [...]
              A simple way of submitting a program to run without a configuration
              file. This mechanism also tells launchd to keep the program alive in the event
              of failure.

              -l label
                       What unique label to assign this job to launchd.

              -p program
                       What program to really execute, regardless of what follows
                       the -- in the submit sub-command.

              -o stdout-path
                       Where to send the stdout of the program.

              -e stderr-path
                       Where to send the stderr of the program.

I believe it will be easier to manage.

Looks good! I think it doesn't have all of the options but it probably should be enough to work.

It now works for me on my system. A weird bug I encountered is that KUBECONFIG won't be correct inside of the scripts.
It will still have the default value. For now I just used "$PWD/files/kubeconfig.yaml" instead.
