Ci for all
- 1. CI for ALL
- 2. Agenda ● CI - Why, What & How ● YAML file and JJB ● CI Work-flow ● Build triggers ● Parameterize the jobs ● Build jobs using JJB ● Q&A session
- 3. Why CI? ● Company Goal ● Delay in response ● Env issues & User errors ● Inefficient use of tools/resources ● Duplicate test reports ● Compromise in Quality
- 4. What does CI do? ● Automatic execution of tests ● Integrate different tools ● Latest & greatest pkgs ● Clean env ● TIER based runs ● Centralized reporting
- 5. How to setup CI? ● Jenkins Master/Slave – Install/Config/Plugin ● Requirements and project details – YAML file – JJB – Jenkins Job Builder ● Triggers ● Repo creation ● Provision & teardown ● Runtest
- 6. ● YAML file and JJB YAML file Global defaults Project vars & Jobs Jenkins vars Json file Restraint xml Builders Parameters Jobs Jenkins Jobs Trigger Repo creation Provision Runtest Teardown Build jobs from Jenkins JJB(Python script) GIT repo Jenkins Master Config file(Creds)
- 7. ● CI work-flow Brew Trigger Provision Resources Runtest Teardown Resources Brew build Redhat CI PluginYAML file Mail Notifications IRC Notifications JMS Selector Brew bus Jenkins Jobs JJB
- 8. Project variables ● jobs: - '{prefix}-{testsuite}-{arch}-provision' - '{prefix}-{testsuite}-{arch}-runtest' - '{prefix}-{testsuite}-{arch}-teardown' ● testsuite: - test1 - test2 - test3 ● Prefix: rhds ● brew-tag: rhel-7.2-candidate ● arch: x86_64
- 9. Variables contd... ● Replace variable with values: – Variable within YAML file ● '{release}' ● '{prefix}-{testsuite}-{arch}-provision' – Parameters ● $PATCH_ID ● $BUILD_ID – Jenkins env variables ● $WORKSPACE ● $JENKINS_HOME
- 10. Build triggers ● Upstream job - Trigger ● Downstream – Provision ● Triggers: - ci-trigger: jms-selector: | CI_TYPE IN ('brew-tag') AND CI_NAME IN ('389-ds-base','nss','openldap') AND tag IN '{brew-tag}'
- 11. Build triggers contd... ● Periodic build trigger ● Jenkins job trigger – Build when jobs built – Build when jobs promoted – Build based on results of multiple jobs ● Script trigger – Shell script ● Gerrit trigger – Gerrit server details – When patchset created, merged
- 12. Provision ● Beaker/Openstack – JSON File – provision_resources.sh ● Upstream job - Trigger ● Downstream job - Runtest ● Copy artifcats – Inject information to RESOURCES.txt
- 13. Provision contd... - builder: name: 'provision-resources' builders: - shell: | #!/bin/bash $WORKSPACE/ci-ops- central/bootstrap/provision_resources.sh --site=$SITE --project_defaults=dirsrv-tests/config/project_defaults --topology={topology}-$PROVISIONER --ssh_keyfile=dirsrv-tests/config/keys/idm-jenkins --name={testsuite} TR_STATUS=$?

- 15. Runtest ● Restraint xml file – Beaker task – Install, configure and execute tests ● Ansible – Ansible playbook – Install pkgs – Run your tests ● Upstream – provision – Bkr job ID, IP address & Hostname ● Downstream - teardown
- 17. ● Jenkins Job Builder builders: - shell: | JENKINS_URL=${JENKINS_URL:-"https://localhost/"} pushd $WORKSPACE/dirsrv-tests Popd cd $WORKSPACE python -m jenkins_jobs.cmd --conf $WORKSPACE/ $CONIG_FILE --flush-cache update $WORKSPACE/ $GIT_REPO/$CI_DIR Example for RHDS: python -m jenkins_jobs.cmd --conf $WORKSPACE/dirsrv-tests/jobs/config --flush-cache update $WORKSPACE/dirsrv-tests/jobs/rhel72
- 18. Parameterize jobs ● Change variable values – Troubleshooting & Manual execution ● choice: name: tag choices: - rhel-7.2-z-candidate - rhel-7.2-candidate description: "Brew tag for this build." ● string: name: REPORT_EMAIL default: redhat-list@redhat.com description: Default email id for reports
- 19. JJB with Gerrit refspec ● Add a parameter - GERRIT_REFSPEC ● Add a build step – Execute shell pushd $WORKSPACE/dirsrv-tests git pull https://code.engineering.redhat.com/gerrit/dirsrv-tests $GERRIT_REFSPEC popd ● cd $WORKSPACE ● python -m jenkins_jobs.cmd --conf $WORKSPACE/dirsrv-tests/jobs/config --flush-cache update $WORKSPACE/dirsrv-tests/jobs/ $GIT_BRANCH
