|
description: |
|
|
Clear the knownhost cache for (default) all the units, a service, or a
|
|
single unit.
|
|
.
|
|
The default is all units. If the 'target' param has an '/' in it, then it
|
|
is assumed ot be a single unit. If no '/' is present, then all the units
|
|
in a service will be refreshed.
|
|
.
|
|
e.g. target="nova-compute/4" will just clear the nova-compute/4 unit (in
|
|
the 'nova-compute' application), whereas target='nova-compute' will refresh
|
|
all of the units in the 'nova-compute' application.
|
|
.
|
|
The action triggers a refresh resolution of the known hosts for the unit,
|
|
which then populates the cache, updates the knownhosts file for the
|
|
associated service (e.g. 'nova-compute'), and, importantly, sets the
|
|
relation data for that associated service with the new knownhosts file.
|
|
This may cause a 'cloud-compute' relation changed hook on the associated
|
|
nova-compute units if the hosts have changed.
|
|
.
|
|
This action still functions even if the 'cache-known-hosts' config value is
|
|
not set; caching of hosts occurs regardless of that setting, and so this
|
|
action can be used to force an update if DNS has changed in the system, or
|
|
for a particular host (although this scenario is unlikely).
