Hey,

Could you provide a bit more information please :

• The jmeter version you're using
• Did you try with the sample scenario ? Like I just cloned the repo and ran a test with the example in the readme source scenario/my-scenario/.env && sudo docker-compose -p jmeter up --scale jmeter-slave=${nbInjector} -d and it worked without issues.
• What is your docker and docker-compose version ?
• Maybe on which arch are you running it ? I tried on an amd64 linux and an ARM from an Apple Silicon and it's working properly
• Please, could you output the raw logs of the docker-compose output ? (no need for the monitoring stack, just jmeter-slave and jmeter-master)

Thanks

i use same command as the example in the readme
i'm not change anything .

it's still got same err

docker and docker-comporse version do i need upgrade them？

by the way
How much of a performance penalty does using jmeter in container choreography compare to deploying jmeter on a physical machine? What's the advantage? I have some vague understanding, I would like to ask

thank you so mush

Yes please try to upgrade your docker stack up to date. Because I'am not able to reproduce your error.

And, what OS are you working on ? Any specificity to know ?

[lyc10031]

it‘s ubuntu 2204 on vmware i will try upgrade my docker and docker-compose newest version

[lyc10031]

after upgrade it's worked。 Thanks a lot。
