getProvisioningFlags(java.util.Collection<java.lang.String> tags)
Gets flags, suitable as an argument to
MachineProvisioningLocation.obtain(Map). |
void |
init()
Called by framework (in new-style instances where spec was used) after configuring etc,
but before a reference to this instance is shared.
|
MachineProvisioningLocation<MachineLocation> |
newSubLocation(java.util.Map<?,?> newFlags)
Creates a new location of the same type, but with additional creation instructions in the form of flags,
e.g.
|
MachineLocation |
obtain(java.util.Map<?,?> flags)
Obtain a machine in this location.
|
void |
release(MachineLocation machine)
Release a previously-obtained machine.

MachineProvisioningLocationMachineProvisioningLocation.obtain(Map). The tags provided give
hints about the machine required. The provisioning-location could be configured to
understand those tags.
For example, an AWS-location could be configured to understand that a particular entity
type (e.g. "TomcatServer") requires a particular AMI in that region, so would return the
required image id.getProvisioningFlags in interface MachineProvisioningLocation<MachineLocation>
