Kubernetes dns performance test report¶
| Abstract: | This document is the report for Kubernetes DNS performance test plan |
|---|
Environment description¶
This report is collected on the hardware described in Intel-Mirantis Performance-Team Lab #1.
Software¶
Kubernetes is installed using Kargo deployment tool on Ubuntu 16.04.1.
- Node roles:
- node1: minion+master+etcd
- node2: minion+master+etcd
- node3: minion+etcd
- node4: minion
- node5: minion
- node6: minion
- Software versions:
- OS: Ubuntu 16.04.1 LTS (Xenial Xerus)
- Kernel: 4.4.0-47-generic
- Docker: 1.13.0
- Kubernetes: v1.5.1+coreos.0 and v1.5.3+coreos.0
Reports¶
Test Case #1: Performing DNS queries¶
Launched script where every next run uses parameters from previous one, but number of req/sec increases on 50.
