How to monitor the status of containers?

Question

Docker

Finally deployed all the containers on the virtual machine

. What are the tools so that if one of the containers falls, it will ping the admin (me)?
A dashboard is not required, a webhook is enough.

Answer 1

If without external tools with a free trial and money for use,
you can receive a live stream of events through the Docker API . Filter only those of interest in it, for example, container=<string>when the name of the container of interest is known and constant.
But in general, take a closer look at the option restart- let the container restart automatically after a fall. And maybe, at startup, it somehow sends “Good morning, admin!”

Answer 2

Write a script that checks the running time of each container in a cycle and if it is less than 5 minutes, send an email / web hook / something else, put the script in cron to execute every 4 minutes
