Environment variables to create user + password

[HariSekhon]

Would it be possible to add support for JENKINS_USER and JENKINS_PASSWORD environment variables to auto-create a user to work with at boot?

Digging out the admin password would then be unnecessary and make it easier to script deterministic usage of Jenkins in docker.

Is it currently possible to do this in any way?

I just find the admin password and start issuing commands, eg. this script:

https://github.com/HariSekhon/DevOps-Bash-tools/blob/master/jenkins/jenkins.sh#L83

which calls this script below to find the password before continuing to issue jenkins cli commands:

I also have a jenkins_cli.sh script to minimize the amount of arguments and make calls simpler (I have a lot of convenience scripts in this repo):

If you're using the default security realm, then you can consider using this init.groovy.d script:

import hudson.security.HudsonPrivateSecurityRealm
import jenkins.model.Jenkins

def jenkins = Jenkins.getInstance()

if (jenkins.getSecurityRealm() instanceof HudsonPrivateSecurityRealm) {
  // Set password, let CasC handle the rest of the configuration
  def username = System.getEnv('JENKINS_USER')
  def password = System.getEnv('JENKINS_PASSWORD')
  jenkins.getSecurityRealm().createAccount(username, password)
}

I don't think that we should implement this in the container, since it assumes the default security realm and many, many users choose other security realms like LDAP, GitHub OAuth, Google OAuth, or ...
