Hi,
I want to build a Zeppelin docker image for my self. The docker image is
based on ubuntu:wily, and has openjdk-8-jre and python3 installed. I also
installed other packages that I need.
After started Zeppelin in the docker, I am able to access the webapp from
my local browser. I tried to execute some simple Python script, and it
works fine. But when I try to run the matplotlib example, I got error
saying that tkinter cannot find the $DISPLAY.
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python3.4/dist-packages/matplotlib/pyplot.py", line
535, in figure
**kwargs)

return new_figure_manager_given_figure(num, figure)

window = Tk.Tk()

self.tk = _tkinter.create(screenName, baseName, className, interactive,
wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable
Some people on the Internet suggested adding matplotlib.use('Agg') at the
beginning of the notebook, but it still does not work for me.
