My mon-based config branch is coming together. The last bit I did was the
CLI commands to set and show config. It didn't come out quite like I
expected it would. Here's what there is:
config dump Show all configuration option(s)
config get <who> {<key>} Show configuration option(s) for an entity
config rm <who> <name> Clear a configuration option for one or more
entities
config set <who> <name> <value> Cet a configuration option for one or more
entities
config show <who> Show running configuration
The show command is the oddball here: it reports what the *daemon* reports
as the running config, which includes other inputs (conf file, overrides,
etc.), while the 'get' and 'dump' are just what the mon stores. I wonder
if there is a better command than 'show'? Maybe 'running' or 'active' or
'report' or something?
A sample from my vstart cluster (vstart is only putting some of its
options in the mon so far, so this shows both conf and mon as sources):
