Supplement
- When you upgrade the
jenkins.war
in docker container, commit to another tag the Entrypoint and CMD is lost
- So can commit specific the Entrypoint and CMD
1docker commit --change='ENTRYPOINT [/usr/bin/tini", "--", "/usr/local/bin/jenkins.sh"]' --change='CMD [/usr/local/bin/jenkins.sh"]' <container_id> new_image_name
Basic settings
- Add Global credentials the Secret is kubernetes login token
- Add new cloud configure in
Manage Jenkins
–> Clouds
- Config the
Kubernetes Clouds
websocket connection, use internal jenkins URL, specific the Pod Labels, Pod Retention: On Failure, Max connections, Seconds to wait for pod
- Add Pod template settings
- Specific Namespace, Usage: Only build jobs with label expressions matching this node
- Container Template:
- jnlp: jenkins/inbound-agent:latest,
- Working directory: /home/jenkins/agent
- Command to run: /usr/local/bin/jenkins-agent
- You can specific Volumes to mount cache etc. NPM, Maven, Nuget, PIP
- You can config more for pod template, merge the raw yaml to tolerations
