Change the type of TaskSpec.Steps to a Step type that embeds Container
Browse files Browse the repository at this point in the history 
- move pkg/merge into v1alpha1 to avoid circular dependency
- move pkg/substitution into v1alpha1 to avoid circular dependency
- change resource interface from Get*ContainerSpec -> *Steps
- change artifact storage interface from GetCopy*Storage*ContainerSpec -> *Steps
- removed some unnecessarily table-driven tests
- squashed whitespace and brackets where possible
