Permission denied: '/home/mitmproxy/.mitmproxy/mitmproxy-ca.pem'

I'm trying to run mitmproxy with the following command:

docker run --rm -it -v ~/.mitmproxy:/home/mitmproxy/.mitmproxy -p 8080:8080 mitmproxy/releases

This is the output I get:

Traceback (most recent call last):
  File "/usr/bin/mitmproxy", line 11, in <module>
    sys.exit(mitmproxy())
  File "/usr/lib/python2.7/site-packages/mitmproxy/main.py", line 56, in mitmproxy
    proxy_config = process_proxy_options(parser, options)

    with open(os.path.join(path, basename + "-ca.pem"), "wb") as f:
IOError: [Errno 13] Permission denied: '/home/mitmproxy/.mitmproxy/mitmproxy-ca.pem'

How can I fix it? :)

The problem here is that the Docker container does not have permissions to write to your ~/. mitmproxy. A simple hacky workaround is to chmod a+wr your .mitmproxy folder. If you have a good - less hacky - solution, I'm happy to include that in the docs. :)
