Description

Node Performance Benchmark

Progress Tracker

• Before Alpha: Initially proposed at Increase maximum pods per node kubernetes#23349 (comment)
  • Write and maintain draft quality doc:
    • Initial doc: https://drive.google.com/file/d/0B5b9gVHyDCGPa2dISk1xa1lmOTQ/view

  • Design Approval: @dchen1107
    • Identify shepherd: @dchen1107
    • Identify secondary/backup contact point: @Random-Liu
  • Write (code + tests + docs) then get them merged.
    • Performance related node e2e tests (density test and resource usage tests):
      • Add density (batch pods creation latency and resource) and resource performance tests to `test-e2e-node' kubernetes#29764
      • Add density (batch pods creation latency and resource) and resource performance tests to `test-e2e-node' built for Linux only kubernetes#30026
      • Add Time Series Data and Labels in Node density test kubernetes#30333
      • Add tag [benchmark] to node-e2e-test where performance limits are not verified kubernetes#30568
      • Add logging time series to benchmark test kubernetes#30786
      • add throughput in perf data and disable --cgroups-per-qos kubernetes#31185
    • Test Infrastructure (benchmark jenkins ci job):
      • WIP: Support benchmark in run_e2e.go and jenkins kubernetes#30425
      • Add benchmark to jenkins kubernetes#31039
      • Add job config for kubelet benchmark ci test test-infra#426
      • skip benchmark in jenkins serial test kubernetes#31164
    • Kubelet tracing:
      • WIP: add operation tracing in kubelet for performance analysis kubernetes#31280 (pending)

FEATURE_STATUS: IN_DEVELOPMENT

Docs

• Write user docs and get them merged in: https://github.com/kubernetes/contrib/blob/master/node-perf-dash/README.md
• User docs go into https://github.com/kubernetes/kubernetes.github.io.
• When the feature has user docs, please add a comment mentioning @kubernetes/docs.
• When you get LGTM, you can check this checkbox, and the reviewer will apply the "docs-complete" label.

Next step:

• Finishing performance tracing
• Publish the link to access the node performance test
• Enable the release process to generate the node performance benchmark

Do we need docs for this task?

[jaredbhatti]

Ping on docs. Any docs needs for this feature?

@dchen1107 Another ping on docs. Any PRs you can point me to?

This is apparently getting publicized in two places:

• A blog post here: https://docs.google.com/document/d/16RiXzmYBBcz1gcdxYi_GA5S9jdc37UZJb624U08O41w/edit
• and via a readme: https://github.com/coufon/contrib/blob/b065e60a23dd1ca630e26ebfeba010ad0b1cf851/node-perf-dash/README.md

We should also add this to our list of internal tools.
