[FIXED] Configure Ansible playbook to skip Jenkins Initial setup

Issue

Hello I'm new to writing Ansible Playbooks but I'm trying to have my playbook install Jenkins. It installs Jenkins just fine but the issue becomes that it wants me to do the initial unlock before installing plugins, creating jobs etc. I've seen in here a few times people saying you just need to add this to your playbook and you should be good. When I add it and then run the playbook it still has this issue even if I do it from a brand new server. Wondering what everyone has done to get by this issue. Thanks for your assistance!

Code I've seen from other posts: Gets error "Cannot get CSRF" when trying to install jenkins-plugin using ANSIBLE

- name: Jenkins Skip startUp for MI
  lineinfile:
    dest=/etc/sysconfig/jenkins
    regexp='^JENKINS_JAVA_OPTIONS='
    line='JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Djenkins.install.runSetupWizard=false"'
  register: result_skip_startup_wizard

My Playbook

---
# jenkins

- name: Create jenkins group
  group:
    name: jenkins
    state: present

- name: Create jenkins user
  user:
    name: jenkins
    group: jenkins
    state: present

- name: Import jenkins gpg key
  rpm_key:
    state: present
    key: http://pkg.jenkins.io/redhat-stable/jenkins.io.key
    validate_certs: no

- name: Download Jenkins repo
  get_url:
    url: http://get.jenkins.io/redhat-stable/jenkins-2.332.3-1.1.noarch.rpm
    dest: /etc/yum.repos.d/

- name: Install java
  yum:
    name: java-11-openjdk
    state: present

- name: Install Jenkins
  package:
    name: /etc/yum.repos.d/jenkins-2.332.3-1.1.noarch.rpm
    state: latest

- name: Jenkins Skip startUp for MI
  lineinfile:
    dest=/etc/sysconfig/jenkins
    regexp='^JENKINS_JAVA_OPTIONS='
    line='JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Djenkins.install.runSetupWizard=false"'
  register: result_skip_startup_wizard

- name: Start and Enable Jenkins
  systemd:
    name: jenkins
    state: started
    enabled: true

- name: Sleep for 30 seconds and continue with Jenkins buildout
  wait_for: timeout=30

For reference this is what I see in the server when I check the file and then when I just grep for the process. jenkins 8474 1 34 18:29 ? 00:00:20 /usr/bin/java -Djava.awt.headless=true -jar /usr/share/java/jenkins.war --webroot=/var/cache/jenkins/war --httpPort=8080

You can see the changes though do get put in the file as mentioned from above. Which makes me think even after restarting the service its not seeing the new option. I even manually stopped jenkins and then started but it still did not pick it up.

JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Djenkins.install.runSetupWizard=false"

Solution

A little late here but I figured I'd leave a comment in here as well as I discovered when I was testing that the setup depended on the version of Jenkins you were attempting to install. Versions I tested are the comment lines above the code. On the latest line it is just an assumption on my part not a guarantee.

# testing for jenkins 2.319.1
- name: Jenkins Skip startUp for MI
  lineinfile:
    dest=/etc/sysconfig/jenkins
    regexp='^JENKINS_JAVA_OPTIONS='
    line='JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Djenkins.install.runSetupWizard=false"'
  register: result_skip_startup_wizard

# below works for 2.332.1 or latest
- name: Jenkins Skip startUp for MI
  lineinfile:
    dest=/usr/lib/systemd/system/jenkins.service
    regexp='^Environment="JAVA_OPTS=-Djava.awt.headless=true'
    line='Environment="JAVA_OPTS=-Djava.awt.headless=true -Djenkins.install.runSetupWizard=false"'
  register: result_skip_startup_wizard
