Hi All,
I have docker desktop installed on my windows laptop and I executed command
docker pull grafana/k6 but somehow docker image is not starting.
Hi @bharati023,
do you can send a image or part of the error?
Maybe you test using another version the K6, example:
docker pull grafana/k6:latest
docker pull grafana/k6:0.55.0
Hi, I tried above commands but still the same issue.
Just wondering, is this the case image will be in exiting mode until we execute any test.
Hi,
do we need to set any path/variable?
Thank you
Hi @bharati023
Yes, we need to set the commands to use K6. In the image maybe you need to use de Command line interface (bash, cmd or powershell).
After the execution docker pull grafana/k6:0.55.0 you execute the command docker run -i grafana/k6:0.55.0 run - <test.js, in this format works for me.
Another way is execute the command docker run --rm -v $(pwd):/scripts -w /scripts grafana/k6:0.55.0 run /scripts/test.js being that /scripts this is your directory with the code
I’m here to help, let me know if it worked
Thank you so much for quick help. it worked. Have a nice day !
docker run -i grafana/k6:0.55.0 run - <firstTest.js

That’s great that it worked! Have a nice day! 
Hi Again,
Just wondering again, why result is showing http_reqs…: 2 1.569723/s because I am checking for single user only.
hi @bharati023
Do you can send a image of the summary metrics?
Hi,
I installed another image as well (v0.54.0) but same issue exist.
Steps for installation: Open command prompt, and execute docker pull grafana/k6:0.54.0
Basic script - import http from ‘k6/http’;
import {sleep} from ‘k6’;
export default function () {
http.get(‘http://test.k6.io’);
sleep(1);
}
Command to execute my script- docker run -i grafana/k6:0.54.0 run - <script.js
Note : I am using IntelliJ as editor.
issues : I see 2 http requests instead of 1.
also my script name is not available in logs. I have attached screenshot for referance
Hi @bharati023
I understand your question, but isn’t a issue. In K6 when isn’t have options in script, the actions of the K6 is “wait” the request and response of the API. If your API performance in a default timeout, the request is sending. For you control the iteration you have use iterations as example below:
In the example I use Options in k6
import http from 'k6/http';
import { sleep } from 'k6';
export const options = {
vus: 1,
iterations: 1,
};
export default function () {
http.get('http://test.k6.io');
sleep(1)
}
really @bharati023 even running locally gives this issue. Maybe this issue is recentend in version 0.55. Try to run in change version in k6 docker, or create a issue in Github K6.
Thank you for quick help. sure I will do that. Have a nice day !
