I have never seen the question before, besides here.
I’m not sure if you can fully disable it actually. But that mostly depends on your Docker environment and if you can prevent the healthcheck from running.
You can disable the crons/jobs by setting the following env JOB_POLL_INTERVAL_MS=0. But that will disable all those jobs, and will disable some notification and cleaning features.
But how to disable the healthcheck, i have no clue. Normally via the docker cli it would be –no-healthcheck. That is something you need to check your host system on how to stop those.
