Nomad clusters are hosted on dedicated servers in the FD.io lab and used to manage Docker container based executors for FD.io project CI jobs.

Physical Lab Infrastructure

Nomad Operational Status

TBD - add description or link to Nomad architecture / configuration

  • TBD - Add links to Nomad monitoring status / data

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.
  • Nomad docker image CI/CD pipeline.
  • Nomad cluster resiliency testing/hardening improvements.
  • 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
  • Convert Jenkins Nomad-plugin configuration spreadsheet to JJB managed YAML configuration files.
  • 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.
