Updating Dependencies and Code Generation

To pull in updates from openshift/api, run the following:

$ go get github.com/openshift/api@<commit or branch>
$ go mod tidy
$ go mod vendor
$ go mod verify

To update the code generation, run the following: Note: GOFLAGS=-mod=vendor needs to be set in the environment.

$ make generate

NOTE: When adding entirely new package make sure to force import it before invoking go get..., go mod tidy and go mod vendor. This will ensure that this new package will be properly picked up in the vendor tree. Only then make generate will be able to correctly create the necessary clients.

How to use it

See examples.

Compatibility

openshift/client-go is backwards compatible with prior server versions back to v3.6 when we switched to API groups. It is not compatible before that.

Keep in mind that using a newer client is generally safe, but the server will strip newer fields it doesn't understand from objects. That means that if you're trying to use a new feature on an old server, the server will do the best it can, but you still won't have the new feature.

Using an older client can be risky if you issue updates (not patches) to existing resources. The older client will remove newer fields on updates. You will not have this problem if you issue patches instead of updates.
