# Ansible Role: Jenkins CI



[![CI](https://github.com/geerlingguy/ansible-role-jenkins/workflows/CI/badge.svg?event=push)](https://github.com/geerlingguy/ansible-role-jenkins/actions?query=workflow%3ACI)



Installs Jenkins CI on RHEL/CentOS and Debian/Ubuntu servers.



## Requirements



Requires `curl` to be installed on the server. Also, newer versions of Jenkins require Java 8+ (see the test playbooks inside the `molecule/default` directory for an example of how to use newer versions of Java for your OS).



## Role Variables



Available variables are listed below, along with default values (see `defaults/main.yml`):



    jenkins_package_state: present



The state of the `jenkins` package install. By default this role installs Jenkins but will not upgrade Jenkins (when using package-based installs). If you want to always update to the latest version, change this to `latest`.



    jenkins_hostname: localhost



The system hostname; usually `localhost` works fine. This will be used during setup to communicate with the running Jenkins instance via HTTP requests.



    jenkins_home: /var/lib/jenkins



The Jenkins home directory which, amongst others, is being used for storing artifacts, workspaces and plugins. This variable allows you to override the default `/var/lib/jenkins` location.



    jenkins_http_port: 8080



The HTTP port for Jenkins' web interface.



    jenkins_admin_username: admin

    jenkins_admin_password: admin



Default admin account credentials which will be created the first time Jenkins is installed.



    jenkins_admin_password_file: ""



Default admin password file which will be created the first time Jenkins is installed as /var/lib/jenkins/secrets/initialAdminPassword



    jenkins_jar_location: /opt/jenkins-cli.jar



The location at which the `jenkins-cli.jar` jarfile will be kept. This is used for communicating with Jenkins via the CLI.



    jenkins_plugins:

      - blueocean

      - name: influxdb

        version: "1.12.1"



Jenkins plugins to be installed automatically during provisioning. Defaults to empty list (`[]`). Items can use name or dictionary with `name` and `version` keys to pin specific version of a plugin.



    jenkins_plugins_install_dependencies: true



Whether Jenkins plugins to be installed should also install any plugin dependencies.



    jenkins_plugins_state: present



Use `latest` to ensure all plugins are running the most up-to-date version. For any plugin that has a specific version set in `jenkins_plugins` list, state `present` will be used instead of `jenkins_plugins_state` value.



    jenkins_plugin_updates_expiration: 86400



Number of seconds after which a new copy of the update-center.json file is downloaded. Set it to 0 if no cache file should be used.



    jenkins_updates_url: "https://updates.jenkins.io"



The URL to use for Jenkins plugin updates and update-center information.



    jenkins_plugin_timeout: 30



The server connection timeout, in seconds, when installing Jenkins plugins.



    jenkins_version: "2.346"

    jenkins_pkg_url: "http://www.example.com"



(Optional) Then Jenkins version can be pinned to any version available on `http://pkg.jenkins-ci.org/debian/` (Debian/Ubuntu) or `http://pkg.jenkins-ci.org/redhat/` (RHEL/CentOS). If the Jenkins version you need is not available in the default package URLs, you can override the URL with your own; set `jenkins_pkg_url` (_Note_: the role depends on the same naming convention that `http://pkg.jenkins-ci.org/` uses).



    jenkins_url_prefix: ""



Used for setting a URL prefix for your Jenkins installation. The option is added as `--prefix={{ jenkins_url_prefix }}` to the Jenkins initialization `java` invocation, so you can access the installation at a path like `http://www.example.com{{ jenkins_url_prefix }}`. Make sure you start the prefix with a `/` (e.g. `/jenkins`).



    jenkins_connection_delay: 5

    jenkins_connection_retries: 60



Amount of time and number of times to wait when connecting to Jenkins after initial startup, to verify that Jenkins is running. Total time to wait = `delay` * `retries`, so by default this role will wait up to 300 seconds before timing out.



    jenkins_prefer_lts: false



By default, this role will install the latest version of Jenkins using the official repositories according to the platform. You can install the current LTS version instead by setting this to `false`.



The default repositories (listed below) can be overridden as well.



    # For RedHat/CentOS:

    jenkins_repo_url: https://pkg.jenkins.io/redhat{{ '-stable' if (jenkins_prefer_lts | bool) else '' }}/jenkins.repo

    jenkins_repo_key_url: https://pkg.jenkins.io/redhat{{ '-stable' if (jenkins_prefer_lts | bool) else '' }}/jenkins.io.key

    

    # For Debian/Ubuntu:

    jenkins_repo_url: deb https://pkg.jenkins.io/debian{{ '-stable' if (jenkins_prefer_lts | bool) else '' }} binary/

    jenkins_repo_key_url: https://pkg.jenkins.io/debian{{ '-stable' if (jenkins_prefer_lts | bool) else '' }}/jenkins.io.key



It is also possible to prevent the repo file from being added by setting  `jenkins_repo_url: ''`. This is useful if, for example, you sign your own packages or run internal package management (e.g. Spacewalk).



    jenkins_options: ""



Extra options (e.g. setting the HTTP keep alive timeout) to pass to Jenkins on startup via `JENKINS_OPTS` in the systemd override.conf file can be configured using the var `jenkins_options`. By default, no options are specified.



    jenkins_java_options: "-Djenkins.install.runSetupWizard=false"



Extra Java options for the Jenkins launch command configured via `JENKINS_JAVA_OPTS` in the systemd override.conf file can be set with the var `jenkins_java_options`. For example, if you want to configure the timezone Jenkins uses, add `-Dorg.apache.commons.jelly.tags.fmt.timeZone=America/New_York`. By default, the option to disable the Jenkins 2.0 setup wizard is added.



    jenkins_init_changes:

      - option: "JENKINS_OPTS"

        value: "{{ jenkins_options }}"

      - option: "JAVA_OPTS"

        value: "{{ jenkins_java_options }}"

      - option: "JENKINS_HOME"

        value: "{{ jenkins_home }}"

      - option: "JENKINS_PREFIX"

        value: "{{ jenkins_url_prefix }}"

      - option: "JENKINS_PORT"

        value: "{{ jenkins_http_port }}"



Changes made to the Jenkins systemd override.conf file; the default set of changes set the configured URL prefix, Jenkins home directory, Jenkins port and adds the configured Jenkins and Java options for Jenkins' startup. You can add other option/value pairs if you need to set other options for the Jenkins systemd override.conf file.



    jenkins_proxy_host: ""

    jenkins_proxy_port: ""

    jenkins_proxy_noproxy:

      - "127.0.0.1"

      - "localhost"



If you are running Jenkins behind a proxy server, configure these options appropriately. Otherwise Jenkins will be configured with a direct Internet connection.



## Dependencies



None.



## Example Playbook



```yaml

- hosts: jenkins

  become: true

  

  vars:

    jenkins_hostname: jenkins.example.com

    java_packages:

      - openjdk-8-jdk



  roles:

    - role: geerlingguy.java

    - role: geerlingguy.jenkins

```



Note that `java_packages` may need different versions depending on your distro (e.g. `openjdk-11-jdk` for Debian 10, or `java-1.8.0-openjdk` for RHEL 7 or 8).
