Unable to start chrome on Jenkins docker container with k6-browser test

Grafana k6 k6-browser

Hello team,
I am trying to run k6-browser test on a Jenkins instance which is in docker container.
The test is failing on starting chrome step with error: /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq: No such file or directory

Here is my Dockerfile

Stage 1: Fetch base image with go

FROM JFrog

Install required packages

RUN apt-get update &&
apt-get install -y git npm sudo &&
useradd -m go &&
adduser go sudo &&
echo ā€˜%sudo ALL=(ALL) NOPASSWD:ALLā€™ >> /etc/sudoers

WORKDIR /app

Install xk6

RUN go install go.k6.io/xk6/cmd/xk6@latest

Stage 2: Build the custom k6 image with extensions

RUN xk6 build v0.53.0
ā€“with GitHub - grafana/xk6-dashboard: A k6 extension that makes k6 metrics available on a web-based dashboard.
ā€“output /usr/local/bin/k6

Here is chrome installation stage in jenkins:

stage (ā€˜Install Chromeā€™) {
when {
expression { params.executor == ā€˜ui-smoke testā€™ || params.exector == ā€˜ui-load testā€™ }
}
steps {
sh ā€˜sudo apt-get --quiet -y install wget zipā€™
// Install chrome dependencies
sh ā€˜sudo apt-get --quiet -y install fonts-liberation libappindicator3-1 xdg-utils libcurl4 libu2f-udev libasound2 libnspr4 libnss3 libvulkan1ā€™
// Install chrome
sh ā€˜sudo wget --quiet --output-document /usr/src/google-chrome.deb ā€œhttps://dl.google.com/linux/direct/google-chrome-stable_current_amd64.debā€ā€™

            sh 'sudo dpkg -i /usr/src/google-chrome.deb ;'
            sh 'sudo apt-get --quiet -y -f install'
            sh 'sudo rm -f /usr/src/google-chrome.deb'
        }
    }

Same test is working perfectly fine on my local windows.

Hi @lucky041295,

This problem is about the operating system and the Chromium version the Docker image uses. Itā€™s better to ask this problem to the operating system or Chromium forums or bug boards. I looked it up, but there is little info about this issue:

Also, make sure that youā€™re running the browser test in HEADLESS mode:

K6_BROWSER_HEADLESS=1 ...

Sorry, I couldnā€™t give the best answer, but I hope it helps.

I solved it by adding parameter K6_BROWSER_ARGS=no-sandbox.
Thanks for the help though.
