I'm running selenium tests inside a docker container, with Firefox and Geckodriver. When running that container as root, everything works fine.
When running the container as non-root user (USER 1000), the driver fails to initialize :
[[1;31mERROR[m] test01_WO_default_dashboard Time elapsed: 132.6 s <<< ERROR!
org.openqa.selenium.TimeoutException:

Relevant parts of my Dockerfile :
FROM ubuntu:20.04
# install firefox
ARG FIREFOX_VERSION=latest
RUN FIREFOX_DOWNLOAD_URL=$(if [ $FIREFOX_VERSION = "latest" ] || [ $FIREFOX_VERSION = "nightly-latest" ] || [ $FIREFOX_VERSION = "devedition-latest" ] || [ $FIREFOX_VERSION = "esr-latest" ]; then echo "https://download.mozilla.org/?product=firefox-$FIREFOX_VERSION-ssl&os=linux64&lang=en-US"; else echo "https://download-installer.cdn.mozilla.net/pub/firefox/releases/$FIREFOX_VERSION/linux-x86_64/en-US/firefox-$FIREFOX_VERSION.tar.bz2"; fi) \

# install geckodriver
ARG GECKODRIVER_VERSION=latest
RUN GK_VERSION=$(if [ ${GECKODRIVER_VERSION:-latest} = "latest" ]; then echo "0.31.0"; else echo $GECKODRIVER_VERSION; fi) \
&& echo "Using GeckoDriver version: "$GK_VERSION \
&& wget --no-verbose -O /tmp/geckodriver.tar.gz https://github.com/mozilla/geckodriver/releases/download/v$GK_VERSION/geckodriver-v$GK_VERSION-linux64.tar.gz \
&& rm -rf /opt/geckodriver \
&& tar -C /opt -zxf /tmp/geckodriver.tar.gz \
&& rm /tmp/geckodriver.tar.gz \
&& mv /opt/geckodriver /opt/geckodriver-$GK_VERSION \
&& chmod 755 /opt/geckodriver-$GK_VERSION \
&& ln -fs /opt/geckodriver-$GK_VERSION /usr/bin/geckodriver \
&& geckodriver --version
I even added some chmod / chown to try and fix some permissions issues with firefox or geckodriver :
RUN chown 1000 -R /usr/bin/geckodriver \
&& chmod 775 -R /usr/bin/geckodriver \
&& chown 1000 -R /usr/bin/firefox \
&& chmod 775 -R /usr/bin/firefox
And finally the USER instruction to run the container as non-root
USER 1000
I do not manually install selenium. It's a maven dependency of the project I'm installing where my tests sources are.

According to this MR https://github.com/SeleniumHQ/docker-selenium/pull/485/files#diff-04c6e90faac2675aa89e2176d2eec7d8R43, it may be fixed by add --shm-size 2g when you start the container.
As the Selenium community provide docker image for Firefox, I think it would be a better choice to use their docker image directly, or create your own based on their dockerfile to reduce the chance of having problem like this.
CodePudding user response：
I met the same issue recently, and tried to solve it by the following Message: Failed to read marionette port
- in Dockerfile create a directory /.cache mkdir -p /.cache;\
and give write permission to /.cache directory chmod 777 /.cache;\
- if you run docker with specified user id (i.e. Jenkins id), then you need to add some username with the userid and groupid in yourcontainername:/etc/passwd echo "somename:x:1234:1235:somename:/tmp:/bin/bash" >> /tmp/passwd
