Perhaps useful to others: jenkins_bcrypt_pw_util. This is a simple script that generates a Jenkins compatible password hash using bcrypt.
bcrypt
Starting up a Jenkins instance to get hold of such a hash for your new Jenkins deployment seemed a bit convoluted
Thanks @gavanderhoorn That looks super useful. This would be great to leverage in the deployment so we could avoid storing the intermediate values in the config and having to keep a parallel record of them.
You mean the admin password and the hash? Yes, I was thinking about that as well.
