ONAP Jenkins Sandbox Process:

ONAP Jenkins Sandbox provides you Jenkins Job testing/experimentation environment that can be used before pushing job templates to the production Jenkins.

It is configured similar to the ONAP [ci-management] production instance; however, it cannot publish artifacts or vote in Gerrit. Be aware that this is a test environment, and as such there is a limited allotment of minions to test on before pushing code to the ONAP repos. Keep the following points in mind prior to beginning work on ONAP Jenkins Sandbox environment:

  • Jobs are automatically deleted every weekend
  • Committers can login and configure Jenkins jobs in the sandbox directly
  • Sandbox jobs CANNOT perform any upload tasks
  • Sandbox jobs CANNOT vote on Gerrit
  • Jenkins nodes are configured using ONAP openstack VMs and you can not access these VMs directly.

Before you proceed further, ensure you have a Linux Foundation ID (LFID), which is required to access Gerrit & Jenkins. Also, to extend your permissions for uploading Jenkins configurations to Sandbox environment, you must raise a ticket to Linux Foundation Help Center

To download ci-management, execute the following command to clone the ci-management repository.

git clone https://gerrit.onap.org/r/ci-management && (cd ci-management && curl -Lo \ $(git rev-parse --git-dir)/hooks/commit-msg https://gerrit.onap.org/r/tools/hooks/commit-msg; \ chmod +x $(git rev-parse --git-dir)/hooks/commit-msg)

Make sure to sync global-jjb submodule using:

git submodule update --init

Once you successfully clone the repository, next step is to install JJB (Jenkins Job Builder) in order to experiment with Jenkins jobs.

Execute the following commands to install JJB on your machine:

cd ci-management
pip install virtualenv
virtualenv onap_sandbox
source onap_sandbox/bin/activate
pip install jenkins-job-builder
jenkins-jobs --version
jenkins-jobs test --recursive jjb/

Make a copy of the example JJB config file (in the ci-management/ directory)

Backup the jenkins.ini.example to jenkins.ini

cp jenkins.ini.example ~/.config/jenkins_jobs/jenkins_jobs.ini

After copying the jenkins.ini.example, modify jenkins.ini with your Jenkins LFID username and API token

[job_builder]
ignore_cache=True
keep_descriptions=False
include_path=.
recursive=True
retain_anchors=True

[jenkins]
user=jwagantall <Provide your Jenkins Sandbox username>
password= <Refer below steps to get API token>
url=https://jenkins.onap.org/sandbox
query_plugins_info=False

How to retrieve API token?

Login to the Jenkins Sandbox, go to your user page by clicking on your username. Click Configure and then click Add new Token. After that specify a token name (optional) and click on Generate to generate and show new token. Please note down your token and store it securely.

To work on existing jobs or create new jobs, navigate to the ci-management/jjb/ directory where you will find all job templates for the project. Follow the below commands to test, update or delete jobs in your sandbox environment.

To Test a Job:

After you modify or create jobs in the above environment, it's good practice to test the job in sandbox environment before you submit this job to production CI environment.

jenkins-jobs test jjb/ <job-name>

Example: jenkins-jobs test jjb/ sdc-master-verify-java

If the job you’d like to test is a template with variables in its name, it must be manually expanded before use. For example, the commonly used template sdc-{stream}-verify-java might expand to sdc-master-verify-java.

A successful test will output the XML description of the Jenkins job described by the specified JJB job name.

Execute the following command to pipe-out to a directory:

jenkins-jobs test jjb/ <job-name> -o <directoryname>

The output directory will contain files with the XML configurations.

To Update a job:

Ensure you’ve configured your jenkins_jobs.ini and verified it by outputting valid XML descriptions of Jenkins jobs. Upon successful verification, execute the following command to update the job to the Jenkins sandbox.

jenkins-jobs update jjb/ <job-name>

Example: jenkins-jobs update jjb/ sdc-master-verify-java

Note that there will be some 403 errors along the way for failed view creation attempts even when the job creation succeeds.

Trigger jobs from Jenkins Sandbox:

Once you push the Jenkins job configuration to the ONAP Sandbox environment, run the job from Jenkins Sandbox webUI. Follow the below process to trigger the build:

Step 1: Login into the Jenkins Sandbox WebUI

Step 2: Click on the job which you want to trigger, then click Build with Parameters, and finally click Build.

Step 3: Verify the Build Executor Status bar and make sure that the build is triggered on the available executor. In Sandbox you may not see all platforms build executors and you don't find many like in production CI environment.

Once the job is triggered, click on the build number to view the job details and the console output.

To Delete a Job:

Execute the following command to Delete a job from Sandbox:

jenkins-jobs delete jjb/ <job-name>

Example: jenkins-jobs delete jjb/ sdc-master-verify-java

The above command would delete the sdc-master-verify-java job.

Modify an Existing Job:

In the ONAP Jenkins sandbox, you can directly edit or modify the job configuration by selecting the job name and clicking on the Configure button. Then, click the Apply and Save buttons to save the job.

However, it is recommended to simply modify the job in your terminal and then follow the previously described steps in To Test a Job and To Update a Job to perform your modifications.
