Outdated Version of `urllib3`

[Aaron]

Nice dockerfile, thanks! For anyone else, I got the following error after running the dockerfile and then executing docker exec <hash> python3 example.py.

INFO:root:Initialized virtual display..
INFO:root:Prepared chrome options..
Traceback (most recent call last):

    **urlopen_kw)
TypeError: urlopen() got multiple values for keyword argument 'body'

This is because I had version 1.7.1 of urllib3 installed in the image (I'm guessing this is the latest one in the repository. See this stackoverflow link

I fixed this issue by adding the following line RUN pip3 install urllib3 --upgrade to line 48 of the dockerfile. Pip complains about system packages but does install the correct one (you can check by adding RUN python3 -c "import urllib3; print(urllib3.__version__)" to the last line of the docker file)

Hi @axj336 ,

I just did a clean rebuild and the urllib3==1.23 got installed.
It is possible you were using a cached version of the image and you may try rebuilding it with the --no-cache option.

[Aaron]

Huh, that didn't work for me. Strange. I wonder if I am using an old version of Ubuntu:trusty. I'm happy to close this issue if you want to.

[Gîra Dumitru]

Maybe this happens if you are using the trusty image. Now the dockerfile is based on xenial image and I have not experienced any issues.

[Aaron]

Yep, looks like xenial fixes it.
