I want to VNC into a running firefox_grid image. I use the Safari browser and vnc://localhost:5900. Apple Screen Sharing shows me a dialog saying "Screen Sharing requires a password to sign in to "localhost"". I get the same result using vnc://0.0.0.0:5900 An empty password does not result in a connection. The system password does not result in a connection.

Note that with the docker-compose file below I can go to http://127.0.0.1:6080 and see the running image by way of noVNC. I need actual VNC in order to manipulate the Firefox browser instance preferences in ways that can not be automated.

This is my docker-compose.yml section describing the image:

firefox:
    image: elgalu/selenium
    depends_on:
      - hub
   # volumes:
   #   - /dev/shm:/dev/shm
    ports:
     # VNC: See what's going on by connecting your VNC client to 0.0.0.0:5900
      - 5900:25900
      # noVNC: See what's going on by hitting http://0.0.0.0:6080 in your browser
      #        Important: http://127.0.0.1:6080 works but http://localhost:6080 doesn't

@chrismcmahon have you checked the readme?
https://github.com/elgalu/docker-selenium#vnc

[chrismcmahon]

The README says "When you don't specify a VNC password, the new default VNC_PASSWORD=no will make it VNC passwordless accessible."

I reported the issue because this seems not to be true. My experience is that a password is required, and I have no password that works.

Ok, then let's wait for @elgalu

[chrismcmahon]

aha, in docker-compose.yml I can specify "VNC_PASSWORD=foo" and get in that way, so there is a workaround if this is a bug

Hi all! from now on I will only be able to give support to project contributors or to users that click and follow the Sponsor button thanks in advance for your support <3

I saw the same issue, and It seems to be a limitation of the default VNC client of OSX, which requires password input. Password-less access works fine from Linux.
