我看不到带有vnc的容器内部

I have a script in php that raises an image of docker (havnesvo / slimerjs) and it passes a .js since the slimer needs a js to boot. When I expose the container and try to see inside with vnc send an error: The host refuse the connection. My script look like:

bash

SCRIPT="script.js"

docker run -p 8080:8080 --rm -ti -v `pwd`:/scripts havnesvo/slimerjs bash -c "sed -i 's/640x480x8/1600x1400x8/' /usr/bin/xvfb-run && /usr/bin/slimerjs /scripts/$SCRIPT"

Any suggestion?
