Usage: $(basename "$0") <generators> <output-package> <internal-apis-package> <extensiona-apis-package> <groups-versions> ...
|
|
|
|
<generators> the generators comma separated to run (deepcopy,defaulter,conversion,client,lister,informer) or "all".
|
|
<output-package> the output package name (e.g. github.com/example/project/pkg/generated).
|
|
<int-apis-package> the internal types dir (e.g. github.com/example/project/pkg/apis).
|
|
<ext-apis-package> the external types dir (e.g. github.com/example/project/pkg/apis or githubcom/example/apis).
|
|
<groups-versions> the groups and their versions in the format "groupA:v1,v2 groupB:v1 groupC:v2", relative
|
|
to <api-package>.
|
|
... arbitrary flags passed to all generator binaries.
|
|
|
|
Examples:
|
|
$(basename "$0") all github.com/example/project/pkg/client github.com/example/project/pkg/apis github.com/example/project/pkg/apis "foo:v1 bar:v1alpha1,v1beta1"
|
|
