This file (together with pkg/expapi/v1/types.go) contain the experimental
|
|
types in kubernetes. These API objects are experimental, meaning that the
|
|
APIs may be broken at any time by the kubernetes team.
|
|
|
|
DISCLAIMER: The implementation of the experimental API group itself is
|
|
a temporary one meant as a stopgap solution until kubernetes has proper
|
|
support for multiple API groups. The transition may require changes
|
|
beyond registration differences. In other words, experimental API group
|
|
support is experimental.
