Last year I made a post on how have a chromium docker on debian. Today it’s a chromium docker on ubuntu.

Install docker on debian

First install this packages :

sudo apt-get install \
        apt-transport-https \
        ca-certificates \
        curl \
        software-properties-common

Then add the repo :

sudo add-apt-repository \
       "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
       $(lsb_release -cs) \
       stable"

Add the key to apt : curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Update package list and install docker :

1	sudo apt-get update && sudo apt-get install docker-ce

Write the docker file

This docker is based on ubuntu stable, so we just have to install chromium, add a user and configure the sound from the container.

To write the docker file, create a empty dir and create a file named Dockerfile :

FROM ubuntu:latest

SHELL ["/bin/bash", "-c"]

# Packages needed for chromium and add a conf line in pulse
RUN apt-get update && apt-get install -yq --no-install-recommends \
    chromium-browser libcurl3 libgl1-mesa-dri libcanberra-gtk-module libexif-dev pulseaudio \
    && rm -rf /tmp/* /var/{tmp,cache}/* /var/lib/{apt,dpkg}/ \
    && echo enable-shm=no >> /etc/pulse/client.conf
# Create a group and a user with same id of host user
RUN groupadd -f -g 1000 user
RUN adduser --uid 1000 --gid 1000 --disabled-login --gecos 'User' user
ENV HOME /home/user 
# Conf for sound
ENV PULSE_SERVER /run/pulse/native
# The command that run chromium with the home page
CMD ["chromium-browser","--no-sandbox", "--no-first-run","http://google.com"]

Build the docker image

1	docker build -t chromium .

Run docker

Command to run :

#!/bin/bash

USER_UID=$(id -u)
USER_GID=$(id -g)
xhost +local:docker

docker run -t --net host --rm -e DISPLAY=$DISPLAY \
  --env=USER_UID=$USER_UID \
  --env=USER_GID=$USER_GID \
  -v /tmp/.X11-unix:/tmp/.X11-unix:ro \
  -v /run/user/$USER_UID/pulse:/run/pulse:ro \
  --device /dev/snd \
  chromium

Details :
- --net host : for having network
- -e DISPLAY:$DISPLAY : for having GUI on host
- USER_(U|G)ID : for having good user and group
- /tmp/.X11-unix:/tmp/.X11-unix:ro : connecting X socket between host and container
- /run/user/$USER_UID/pulse:/run/pulse:ro and --device /dev/snd : for having sound
