Is .withNewSpec() available here?

  .withNewSpec()
     .withFrom( )
  .endSpec

[mluckam]

Yes it is. This helps reduce the nesting. Thanks for the idea.

[rohanKanojia]

Why not use ObjectReferenceBuilder here?

[mluckam]

Oversight, will update.

@mluckam : What is the use case for this change? How do you plan to use this object from openshift-model? Do you also plan to make subsequent changes in OpenShiftClient DSL ?

The DeploymentConfigRollback is utilized to rollback a DeploymentConfig via the API path "/apis/apps.openshift.io/v1/namespaces/{namespace}/deploymentconfigs/{name}/rollback", see documentation. The model DeploymentConfigRollback was not currently in this project, but available in the dependent model project.

Currently I am migrating to utilizing the kubernetes and openshift models from this project. Once the models from this project are utilized, a next step would be to transition from interacting with the API via an HTTP client, to utilizing the OpenShiftClient. This may be several months away though. Until this migration occurs, I do not have plans to update the OpenShiftClient DSL.

@mluckam : Could you please create an issue for /rollback support in OpenShiftClient DSL?
