jenkins_casc_jenkins_port: 8080

HTTP port of the jenkins instance.

jenkins_casc_jenkins_url_prefix: ""

Url prefix of the jenkins instance, e.g. when running in tomcat.

jenkins_casc_config_path_configure: false

Enables / Disabling the configuration of the configuration path. When this value is set to true the JcasC path in the Jenkins instance is set to jenkins_casc_config_path. When the path differs from the previous set path the configuration is directly reloaded.

Config files/templates to upload. When the result of this step is changed the configuration will be reloaded.

jenkins_casc_config_unmanaged_delete: false

Controls if files that existing files in the 'jenkins_casc_config_path' are deleted when they are not included in the 'jenkins_casc_config_fileglobs'. Deletion will only be executed when at least one file was uploaded to the 'jenkins_casc_config_path'.

jenkins_casc_script_timeout: 60

The timeout for jenkins_script tasks in seconds.

jenkins_casc_plugins_present:
  - name: configuration-as-code

# Example:
# - id: credential-id
#   value: credential-value

List of id/value credential pairs. The id can then be referenced in jcasc with ${id} as value reference.

Dependencies

This role depends on the wcm_io_devops.jenkins_plugins role to install/uninstall the plugins.

As transitive dependency this role uses the wcm_io_devops.jenkins_facts role to retrieve the list of installed plugins from the Jenkins instance.

Example Playbook

This playbook will set the JCasC configuration path to /var/lib/jenkins/jcasc-folder and will deploy all .yml and .yaml files found below file/jcasc/my-jenkins/ to this folder.

- name: "Deploy jcasc"
  hosts: jenkins
  vars:
    jenkins_casc_config_path_configure: true
    jenkins_casc_config_path: "/var/lib/jenkins/jcasc-folder"
    jenkins_casc_config_fileglobs:
        - file/jcasc/my-jenkins/*.yml
        - file/jcasc/my-jenkins/*.yaml
  roles:
    - wcm_io_devops.jenkins_configuration_as_code
