What is balena-healthcheck-image?

I noticed that once in a while something called “balena-healthcheck-image” comes up, stays on for a few seconds and then dies off. What is that?

Hi, this is part of balena-engine’s own healthcheck.
You can inspect the image using balena inspect on device, you will find that it’s just a renamed official docker hello-world image: https://hub.docker.com/_/hello-world
