Where does the healthcheck command come from

Is this a docs issue?

• [X] My issue is about the documentation content or website

Type of issue

Information is incorrect

Description

As one might not be aware of where this command comes from the documentation fails to identify what it does and how it gets into the container as it is not part of the application being deployed into the container.

test: [ "CMD", "pg_isready" ]

Location

https://docs.docker.com/language/nodejs/develop/

Suggestion

Elaborate as to where this comes from, it would be fine to identify that it is part of an external resource and link out to it. but it really should be identified so that readers of the tutorial do not have to have advance knowledge of all the systems being illustrated in the tutorial content.
