description:
- registers services and checks for an agent with a consul cluster. A service
is some process running on the agent node that should be advertised by
consul's discovery mechanism. It may optionally supply a check definition
that will be used to notify the consul cluster of the health of the service.
consul's discovery mechanism. It may optionally supply a check definition,
a periodic service test to notify the consul cluster of service's health.
Checks may also be registered per node e.g. disk usage, or cpu usage and
notify the health of the entire node to the cluster.
Service level checks do not require a check name or id as these are derived
by Consul from the Service name and id respectively by appending 'service:'.
Node level checks require a check_name and optionally a check_id Currently,
there is no complete way to retrieve the script, interval or ttl metadata for
a registered check. Without this metadata it is not possible to tell if
the data supplied with ansible represents a change to a check. As a result
this does not attempt to determine changes and will always report a changed
occurred. An api method is planned to supply this metadata so at that stage
change management will be added.
