terraform-provider-kops - WIP

Road to 0.0.1-alpha

• Implement kops/v1alpha2/Cluster flattening to TF state
• Implement kops_cluster resource state sync
• Implement kops/v1alpha2/InstanceGroup flattening to TF state
• Implement kops_instance_group resource state sync
• Cover flattening/expanding of state by UTs
• Fill in spec defaults using cloudup package
• Deep validate spec using cloudup package
• Run create cluster cmd

Roadmap

• Run rolling-update cluster cmd automatically
• Implement Cluster datasource
• Implement InstanceGroup datasource
• Implement Keystore datasource
• Implement Secretstore datasource
• Implement SSHSecretstore datasource
• Add e2e tests
