Usage

write config

cat > test.ini <<\EOT
[readtest]
blocksize=4k
filename=/data/test_file
rw=randread
direct=1
buffered=0
ioengine=libaio
iodepth=256
runtime=120
filesize=8G
[writetest]
blocksize=4k
filename=/data/test_file
rw=randwrite
direct=1
buffered=0
ioengine=libaio
iodepth=16
runtime=120
filesize=8G
EOT

Run single test

docker run --net=host -ti --rm -v "$PWD:/config" kvaps/fio --client=10.112.0.104 /config/test.ini

Run multiple test

First you need to know all IPs for your fio pods:

kubectl get pod -l app=fio -o custom-columns=IP:.status.podIP | tail -n+2 | xargs

Then you can run massfio script with them:

# Run massfio container
docker run --net=host -ti --rm -v "$PWD:/config" -v "$PWD/results:/results" kvaps/massfio

# Run test
timeout 10m /massfio.sh /config/test.ini 10.112.0.104 10.112.0.105 10.112.0.106

# Parse results
/massfio_parse.sh /results
