I have a couple of issues:

1. I think "gui" needs to be the last item on the command line

my "" bash script:


docker run \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  -h $HOSTNAME \
  -v $HOME/.Xauthority:/home/$USER/.Xauthority \

The above works for me but, I still get

Gtk-Message: Failed to load module "canberra-gtk-module"

2. This brings up Firefox, but
The FF that comes up has all of my Bookmarks, tabs, ... etc - why?
FF version 47.0 -
With Firefox, for example, you might want to see how your application
behaves with no web cache, bookmarks, or search history in a repeatable way for test-
ing purposes.

Update on firefox starting with my bookmarks ... etc

After some googling I found:
buried in the comment section I found: see DJon, Oded Arbel comments
Its a "feature" of Firefox - when you start Firefox it checks to see if there is another Firefox running that it can communicate with, which it does using the X11 protocol, and if so it creates a new window with the existing Firefox instance.

So, If I exit (all) my Firefox windows and then do a docker run I get a fresh FF.
A slight gotcha here is I am directed to FF config pages, not really what I want.

My goal is similar to your statement: "... With Firefox, ... you may want to see how your app behaves with no web cache..."
It looks like part of the solution is to use firefox command line option '-P' for profile.
I found this: see launch commands, where he is mounting my profile
in read-only mode. This is not quite what I want. I'd like to create a separate profile for testing, keep a "virgin" copy on my host
and copy it to the container.

any thoughts on how I can do this?

BTW: Jessie Frazelle is a another resource on this topic: see
see GUIs/Chrome

Here is what I did:

1) /path-to-my-container/firefox-docker

firefox -P "Tester" -profile "./profile/tester"   # creates a new profile on my host
cd profile
tar -czf tester-profile-ff.tar.gz tester/

2) changes to the Dockerfile
FROM ubuntu:14.04

RUN apt-get update \
    && apt-get install -y firefox 

RUN groupadd \
    -g 1000 tester
RUN useradd \
    -d /home/tester \
    -s /bin/bash \
    -m tester \
    -u 1000 \
    -g 1000
USER tester
ENV HOME /home/tester
RUN mkdir -p /home/tester/profile
ADD ./profile/tester-profile-ff.tar.gz /home/tester/profile
RUN chown -R tester:tester /home/tester/profile
CMD /usr/bin/firefox -new-instance -P "Tester" -profile "/home/tester/profile/tester"

build the image:
docker build -t gui .

docker run \
  --rm \
  -v /tmp/.X11-unix:/tmp/.X11-unix \
  -h $HOSTNAME \
  -v $HOME/.Xauthority:/home/$USER/.Xauthority \

power it up
 ./ &   # put it in the background, so I can run a bunch if I want to

check docker ps
docker ps

- I'm not quite sure how .Xauthority works in this case, as I am "me" on the host and "tester" on the container
- After running for a few minutes, I see a bunch of warnings from firefox on my host. I seems to be related to
the profile I copied to the container. Probably have to look more into the initialization of the profile, before
copying it. The warnings are having to do with ... updates property ...
