Method: OpenStack::Compute::Server#populate

Defined in:
lib/openstack/compute/server.rb

#populate(data = nil) ⇒ Object Also known as: refresh

Makes the actual API call to get information about the given server object. If you are attempting to track the status or project of a server object (for example, when rebuilding, creating, or resizing a server), you will likely call this method within a loop until the status becomes “ACTIVE” or other conditions are met.

Returns true if the API call succeeds.

=> true
