FIO | openEuler

Current FIO docker images are built on the openEuler. This repository is free to use and exempted from per-user rate limits.

FIO was originally written to save me the hassle of writing special test case programs when I wanted to test a specific workload, either for performance reasons or to find/reproduce a bug. The process of writing such a test app can be tiresome, especially if you have to do it often. Hence I needed a tool that would be able to simulate a given I/O workload without resorting to writing a tailored test case again and again.

Supported tags and respective Dockerfile links

The tag of each fio docker image is consist of the version of fio and the version of basic image. The details are as follows

Usage

In this usage, users can select the corresponding {Tag} based on their requirements.

• Run with an interactive shell

  To perform a simple disk I/O benchmark using FIO inside a Docker container:

  docker run -it --rm --privileged openeuler/fio:{Tag} bash
  

• Basic random read test

  Run this minimal FIO test inside the container:

  fio --name=quick_test \
  --rw=randread \       # Random read pattern
  --size=100M \         # Test file size (reduced to 100MB)
  --bs=4k \             # 4KB block size
  --numjobs=1 \         # Single thread (simplified test)
  --runtime=10s \       # Test duration (reduced to 10 seconds)
  --filename=/data/testfile \  # Test file location
  --ioengine=libaio \   # Asynchronous I/O engine
  --group_reporting     # Consolidated output
