Dear All,
I'd like to have some confirmation about the mechanism that is going to
be used to inform Heat's clients about instance create and destroy in an
auto-scaling group. I am referring to the wiki page at
https://wiki.openstack.org/wiki/Heat/AutoScaling.
I assume, but I may be wrong, that the same eventing mechanism than the
one being used for stack creation will be used...
An instance create in an auto-scaling group will generate an IN_PROGRESS
event for the instance being created followed by CREATE_COMPLETE or
CREATE_FAILED based on the value returned by cfn-signal. Similarly, an
instance destroy will generate a DELETE_IN_PROGRESS event for the
instance being destroyed followed by a DELETE_COMPLETE or DELETE_FAILED
in case the instance can't be destroyed in the group.
Adding a group id in the event details will be helpful to figure out
what group the instance belongs to.
Thanks in advance for the clarification.
Patrick
