Run xk6 browser in Buildkite pipeline throws panic error

[markxk6]

Hi xk6 team,

Good day,

Anyone who tried running xk6 browser using buildkite pipeline or do we have an example of it? i tried to run using buildkite but seeing an error as below, although running with local using docker works fine and looks good. thanks. Below are the screenshots for panic error:

Sometimes, when running the build, it just throws nothing… and needs to cancel the build since it runs already long enough. Below is a screenshot of a canceled build after 15mins of running and still nothing happens.

Note: Same setup (buildkite config) in running my k6 API scripts and no errors so far. Error happens when running xk6 browser.

Hi @markxk6,

Can you send us:

1. The version of xk6-browser you are running;
2. The dockerfile/docker-compose file you are using to create the image;
3. The test file itself;
4. The BuiltKite configuration file (if there is one).

I’ve not used BuildKite before, but I’m hoping I can still be of help.

Cheers,
Ankur

Hi @ankur

Sorry for the late reply,

Here’s the sample dockerfile used for the image:

FROM golang:1.17-alpine as builder
WORKDIR "$GOPATH"/src/go.k6.io/k6

RUN apk --no-cache add git &&\
    go install -trimpath go.k6.io/xk6/cmd/xk6@latest &&\
    xk6 build --output xk6-browser --with github.com/grafana/xk6-browser &&\
    cp xk6-browser "$GOPATH"/bin/k6

FROM alpine:3.16

That is the same setup for our API k6 scripts which runs smoothly in Buildkite. The setup is working as well when we run those scripts in our local (xk6-browser). The issue happens when we build a test for xk6-browser (UI) using Buildkite.

Thanks a lot

When i re-run the scripts, it throws this error SIGILL: illegal instruction

and another error is [signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0x8]
