6.8. Fuel Containerized Control Plane performance report during upgrade¶

Abstract: This document includes Fuel CCP control plane performance test results for various environments (from 50 to 350 nodes). All tests have been performed regarding Fuel Containerized Control Plane upgradability performance testing

6.8.1. Environment description¶

For Kubernetes pre-deployment Kargo tool was used. More information about fuel-ccp and how it can be installed can be found in official documentation.

6.8.1.1. Hardware configuration of each server¶

All servers have configuration describing in table below

6.8.1.2. Network configuration of each server¶

All servers have same network configuration:

6.8.1.3. Fuel CCP configuration¶

CCP main configuration ccp.yaml

CCP Cluster configuration configs.yaml

CCP Cluster topology topology.yaml

CCP repositories configuration repos.yaml

CCP versions configuration for Mitaka versions-mitaka.yaml

CCP versions configuration for upgrade from Mitaka to Newton versions-newton.yaml

6.8.1.4. Rally configuration and scenario¶

Rally deployment rally_deployment.json

Rally scenario create_and_delete.yaml

6.8.1.5. Upgrade and tests procedure¶

Install fuel-ccp
Rename ccp.yaml to /root/.ccp.ymal
Copy all yaml files to /root/
Rename versions-mitaka.yaml to versions.yaml
Execute ccp deploy and wait ok status for all services
Create rally deployment with rally_deployment.json
Create role for rally openstack --insecure role create member
Start rally tests rally task start --task-args 'gre_enabled: true' ./create_and_delete.yaml
Rename versions-newton.yaml to versions.yaml
Execute ccp deploy and wait ok status for all services
Wait tests results from rally

6.8.2. Test results¶

6.8.2.1. Test Case 1: Boot and delete server¶

The following set of results is dedicated to investigate how Nova installed against Kubernetes cluster via fuel-ccp tool is behaving during update from Mitaka to Newton. Upgrade started on 100 iteration and finished on the 156 iteration.

6.8.2.1.1. 149 nodes OpenStack cluster, concurrency 5, 1530 iterations¶

NovaServers.boot_and_delete_server scenario in upgrade_newton_to_mitaka.html

Boot and delete servers Rally scenario (200 nodes)

Operation	Median (sec)	90%ile (sec)	95%ile (sec)	Max (sec)	Min (sec)
boot_server	11.879	16.753	18.708	48.84	7.563
delete_server	2.593	4.754	4.898	6.829	2.313

The control plane downtime of keystone upgrades will be avoided in the feature versions of fuel-ccp
