AttachISO task creates the user-data/meta-data cloud init files and creates cloud-init.iso file using "genisoimage" tool. It then uploads it to the datastore where the master/worker VM resides and inserts it into the cd-rom device of the master/worker VM. When the master/worker VM powers on, the cloud-init package in it runs the bootstrap script that downloads nodeup and runs it.
Also removed redundant VirtualMachineModelBuilder that does nothing.
Testing done:
1. Tested end to end that the master and worker VMs executes the cloud-init script successfully.
2, "make ci" is successful.
Implemented CreateLinkClonedVM cloud interface to create a link cloned VM from a template VM. The code checks if the template VM has a snapshot, if no it creates it before creating a link cloned VM. If snapshot already exists, it uses it to create the link cloned VM.
Testing done:
1. kops cluster create goes through fine and creates the link cloned VM for the master and worker. Verified that it creates the snapshot on the template VM if it does not exists before creating a link cloned VM. In case the snapshot exists, it uses it to create the link cloned VM.
2. "make ci" is successful.
