Cannot access port :9222

[maelp]

Hi, I tried to do a cross between your Docker base image to have VNC and the image of https://github.com/jlandure/alpine-chrome/tree/master to get a chromium that I can use with Puppeteer

for some reason, when using https://github.com/jlandure/alpine-chrome/tree/master directly, I can expose port 9222 and add --remote-debugging-address=0.0.0.0 --remote-debugging-port=9222 to the chromium-browser command and it works

but when I'm doing this from your base image, all the rest being (mostly) the same (check https://github.com/maelp/docker-vnc-chromium) I cannot connect there

perhaps there's some firewall thing somewhere that I need to adapt? do you have any idea?
