Redis does not replicate configuration changes made via the
command. Nor does Sentinel. This is a small tool which is meant to
reside on a sentinel to read it's config and synchronize all monitored
slaves with their master's for a list of configuration directives.
The configuration options currently available are telling configsync
where to find the Sentinel config file and what directives to
synchronize. By default it will look to

CONFIGSYNC_SYNCABLEDIRECTIVELIST can be a single directive or
a comma separated list of directives to synchronize to the slave(s).
If you want to run it in "pretend" mode:
Generally this is expected to be put into a cron table to run perodically. It has been tested running against a sentinel with 100 monitored pods and runs in under half a second, so should be safe to run every minute if desired.
