| Usage: $(basename "$0") <generators> <output-package> <apis-package> <groups-versions> ... |
| |
| <generators> the generators comma separated to run (deepcopy,defaulter,client,lister,informer) or "all". |
| <output-package> the output package name (e.g. github.com/example/project/pkg/generated). |
| <apis-package> the external types dir (e.g. github.com/example/api or github.com/example/project/pkg/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 "foo:v1 bar:v1alpha1,v1beta1" |
| $(basename "$0") deepcopy,client github.com/example/project/pkg/client github.com/example/project/pkg/apis "foo:v1 bar:v1alpha1,v1beta1" |
