This HowTo describes how to add the monitor stack to your software release in the context of html5as-base software release.

Here is the commit introducing this functionality to html5as software release: commit diff.

Services that are not running will be started automatically at the end of an instanciation.

If a monitored Service exit, the signal will trigger an alert to the local SlapOS master forcing the reprocessing of the instance and all its dependecies in order to get back to an expected state. The -on-watch postfix is added to the service name in supervisord in order to mark this service as monitored.

Change the executable launcher from ${basedirectory:script} to ${basedirectory:service}

[html5as]
...
# Executables
bin_launcher = ${basedirectory:service}/launcher
