Docker self-killing container (romeo and juliet)?

Question

linux

How to make it so that when starting containers, if one falls, then the second one stops?

Answer 1

In general, docker-type systems follow the reverse strategy - if something falls, then it is desirable to automatically raise it again, and all other containers should be ready for this.
However, you can probably make a third container, the only task of which will be to check the status of the first container and stop the second one if necessary.

Answer 2

The watchdog's function should lie on the application in a dependent container (fall when the dependency is unavailable), the containers themselves are isolated from each other.
