[mosquitto-dev] Implementing health check for containerized MQTT server

[Steve Prior <sprior@xxxxxxxxxxxx>]

I've written a number of server applications that perform work based on MQTT 
subscriptions and deployed those applications in Docker containers.  What I 
haven't done yet is set up container health checking for those applications.  I 
was wondering what patterns for health checking people have found effective?  
These applications don't have any interface besides the MQTT subscriptions and 
published response - no REST API.

Thanks
