kubeapiserver: rename `--experimental-bootstrap-token-auth` to `--enable-bootstrap-token-auth`. #51198

mattmoyer · 2017-08-23T15:00:39Z

#What this PR does / why we need it:
This change renames the API server --experimental-bootstrap-token-auth flag to --enable-bootstrap-token-auth. The old flag is accepted but generates a warning.

In 1.9, we will drop support for --experimental-bootstrap-token-auth entirely.

Example of the warning log:

$ kube-apiserver --experimental-bootstrap-token-auth --etcd-servers https://127.0.0.1:1234 --service-cluster-ip-range 10.0.1.0/24
Flag --experimental-bootstrap-token-auth has been deprecated, use --enable-bootstrap-token-auth instead.
[...]

Which issue this PR fixes fixes #50613

Release note:

Renamed the API server flag `--experimental-bootstrap-token-auth` to `--enable-bootstrap-token-auth`. The old value is accepted with a warning in 1.8 and will be removed in 1.9.

nit: Enable and DeprecatedEnableExperimental or something?

Yeah, that sounds good. Will fix.

don't spread flag-specific things into the options structs... keep the single bool, bind two flags to it, and use fs.MarkDeprecated on the old flag

Thanks, I was looking for something like fs.MarkDeprecated but didn't find it. This is much better.

This flag was replaced by `--enable-bootstrap-token-auth` in 1.8 (kubernetes#51198).

Drop --experimental-bootstrap-token-auth flag. **What this PR does / why we need it**: Drops support for the `--experimental-bootstrap-token-auth` flag for the API server.
