| # An easy way to quickly test local changes. | ||
| # | ||
| # The approach taken was to start the aws-iam-authenticator as | ||
| # a separate docker container first, with a fixed IP and in the | ||
| # kind node network. Then, generate the webhook | ||
| # config with that IP and start the kind cluster. | ||
| # | ||
| # Alternative approach: we could run the authenticator pod in | ||
| # the kind cluster. This might be a future improvement: | ||
| # pregenerate all certificates and config, start the cluster, | ||
| # load the target authenticator image, run authenticator as a | ||
| # host network pod (same as API server), and all communication | ||
| # between them is over localhost and fixed port. | ||
