I’m wanting to run k6 via docker to enable the devs/qa to execute without any local dependencies.
I’m no docker expert so am struggling getting it working.
Following the guide here Running k6 I was able to get a simple script working as expected.
However, I have more complex scripts which access other modules, data and config files which are located in sub-directories.
- plugins (e.g. modules uuid.js)
- config (e.g. json files with vu, duration, etc)
- data (csv files for test execution)
I suspect I’ll be having to use the docker -v command but not sure how best to do so.
Let me try to help you!
Yes, considering the
docker -run v is the right direction.
let’s say you have a directory that contains some files:
│ └── users.json
Here the config.json is k6’s config file. The
users.json is just some data file that I will use in the tests. And the http_get.js is the test script.
If I run the command:
docker run --rm -v $(pwd):/scripts loadimpact/k6:latest run /scripts/http_get.js
It will mount the current directory (what the
pwd returns) as the
/scripts inside the container. And execute the following command inside the container.
k6 run /scripts/http_get.js
My http_get.js can use any resource located in the same directory. Just use a relative path, like:
const f = open('data/users.json');
If I want to use the config.json to run my k6, it will look like this:
docker run --rm -v $(pwd):/scripts loadimpact/k6:latest run --config /scripts/config.json /scripts/http_get.js
Let me know if that helps!
Awesome, thanks so much.
Doesn’t work that well on my windows machine as directory sharing with docker is a bit patchy but works brilliantly on my mac which is what all the developers use anyway
