Hi @webdawg. Thanks for your PR.

I'm waiting for a etcd-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

@webdawg

1. To pass the DCO check, you have to signoff your commit off all your commit to always include Signed-off-by: Author Name [email protected] in every commit message.
   You can also do this automatically by using the -s flag (i.e., git commit -s).

2. Could you please elaborate on the testing you have done to achive a successful execution of thi script and add it to the PR description ?

[jberkus]

Also: this is the version of the script to create a config file. The one that belongs in /website should be the version that generates the output for configuration.md. They'd both be pretty similar -- or even one script with switches -- but that's what we need in this location.
