kimage-performance

kimage-performance is a Docker image designed for capturing test and performance data in Kubernetes environments. It provides a comprehensive set of tools for benchmarking, network performance testing, and database performance evaluation.

Features

Pre-installed tools: The image comes pre-installed with a variety of tools for performance testing, including:

  • sysbench: A versatile tool for benchmarking CPU, memory, file I/O, and database performance.
  • speedtest-cli: A command-line tool for measuring internet bandwidth.
  • fio: A high-performance I/O benchmarking tool.
  • ffmpeg: A powerful multimedia framework for encoding, decoding, and transcoding audio and video.
  • wrk: A HTTP benchmarking tool for measuring the performance of web servers.
  • iperf: A tool for measuring the maximum achievable bandwidth on IP networks.
  • apache2-utils: A collection of utilities for managing Apache web servers but here installed for ap (Apache Bench).

Easy to use: The image is easy to use and can be run with a simple kubectl run command.

Customizable: The image can be customized to meet your specific needs by adding additional tools or modifying the configuration.

Usage

To use the kimage-performance image, you can run the following command:

kubectl run performance-test-pod -ti --rm --restart=Never --image=ghcr.io/r3m1n0x/kimage -- $COMMAND

or you probably want to use ist as a manifest:

apiVersion: v1
kind: Pod
metadata:
  creationTimestamp: null
  labels:
    run: performance-pod
  name: performance-pod
  namespace: testing
spec:
  containers:
  - image: ghcr.io/r3m1n0x/kimage-performance:latest
    name: perfromance-pod
    resources:
      limits:
        memory: 2Gi
        cpu: 1000m
      requests:
        memory: 2Gi
        cpu: 1000m
    command: [ "/bin/bash", "-c", "--" ]
    args: [ "while true; do sleep 60; done;" ]
    securityContext:
      allowPrivilegeEscalation: true
    imagePullPolicy: Always
  dnsPolicy: ClusterFirst
  restartPolicy: Never
status: {}

This will start a container based on the image and you can then use the pre-installed tools to perform your tests.

Examples

For example, to run a CPU benchmark using sysbench, you can run the following command:

sysbench cpu --cpu-count 4 --threads 8 --time 60

To measure your internet bandwidth using speedtest-cli, you can run the following command:

speedtest-cli
