=== Proposed Jenkins Nomad Plugin Label to Docker Image Mapping ===
 
−
Jenkins Nomad Plugin Labels can only be created via LF Service Desk requests. 
 
−
In order to test CI jobs in the Jenkins Sandbox, a different label must exist
 
−
which points to a sandbox Dockerhub repository to avoid disrupting operational
 
−
jobs during docker image testing. This is the proposed nomenclature for the
 
−
mapping of Jenkins Nomad Plugin labels and the corresponding dockerhub repositories
 
−
(production and sandbox variants).
 
−
 
−
All new docker images will first be pushed to the Dockerhub associated 'sandbox repo'
 
−
and all CI jobs utilizing the Jenkins Nomad Plugin Label will be verified in the Jenkins
 
−
Sandbox, by modifying the appropriate JJB YAML files to point to the sandbox repo.
 
−
Once all CI jobs have been verified, then the image will be pushed to the operational
 
−
dockerhub repository associated with the label.
 
−
 
−
'''NOTE''': the 'sandbox labels' should NEVER be merged into the ci-management repository.

=== Legacy Jenkins Label to Docker Image Mapping ===

Nomad Planning Wish List

This is the list of long term Nomad tasks. Please move them to the Nomad Operations Tasks and provide owner/ET information when they are being actively worked on.

  • Clean up old/unused Jenkins jobs.
  • Use Configuration as Code Jenkins Plugin to manage Jenkins configuration (including Nomad Plugin) via YAML configuration files.
  • Nomad cluster resiliency testing/hardening improvements.
  • Nomad docker image CI/CD pipeline.
  • Convert task list to use JIRA tickets/epics for tracking ongoing Nomad work.
  • Create ci-management jobs to do automated build/test/verify for CI process and weekly upgrade of docker images.
  • Add Nomad nodes to LF DNS & make the names the same as the hostname.
  • Add automated Nomad server quorum loss tests
  • Add VPP "test crash" testcase to 'make test'
  • Add VPP 'make test-debug w/ ASAN enabled' verify job
  • Investigate Jenkins Nomad-plugin security issues.
  • Convert Nomad/Jenkins/Gerrit monitoring/screen-scraping hacks into an operational monitoring system using exported gerrit & jenkins logs & nomad cli output.
  • Add a mechanism to measure/track the memory consumed by the CI jobs inside Docker images. pmikus_comment: Depends if we want ability to do live monitoring or ability of storing logs (how long?). I can make prometheus to work for us by very simple change in config.
