Hi @sahil1610,

Can you share with us the docker command you are using to start the container?

I can actually see in the log you posted that the parameter is being received:

appending selenium options: -enablePassThrough false

Why do say that it was not set?

[sahil1610]

I am passing these through docker compose:

environment:
- no_proxy=localhost
- TZ=Europe/London
- HUB_PORT_4444_TCP_ADDR=progrid
- HUB_PORT_4444_TCP_PORT=4444
- SE_OPTS=-enablePassThrough false

And when I check this on hub console, enablePassThrough is still true.

@diemol any help on this?

Hi @sahil1610,

I tried with this docker-compose file:

# To execute this docker-compose yml file use docker-compose -f <file_name> up
# Add the "-d" flag at the end for deattached execution
version: '2'
services:
  firefox:
    image: selenium/node-firefox:3.8.1-dubnium
    volumes:
      - /dev/shm:/dev/shm
    depends_on:
      - hub
    environment:
      - HUB_HOST=hub
      - no_proxy=localhost
      - TZ=Europe/London

  chrome:
    image: selenium/node-chrome:3.8.1-dubnium
    volumes:
      - /dev/shm:/dev/shm
    depends_on:
      - hub
    environment:
      - HUB_HOST=hub
      - no_proxy=localhost
      - TZ=Europe/London

  hub:
    image: selenium/hub:3.8.1-dubnium
    ports:
      - "4444:4444"
    environment:
      - SE_OPTS=-enablePassThrough false

and the value enablePassThrough is set to false in the hub.

If you were referring to the nodes, it seems that no matter what you set, the value will be shown as true. But according to my checks, the important value is the one set in the hub.

Additionally, I also found out that this flag will be removed in the next Selenium release, which means that "enablePassThrough=true" always.

Thanks @diemol.

This indeed is working to set enablePassThrough to false for the hub.

But this doesn't make actions library to work in firefox, which is actually working if I am NOT using selenium grid.

Any idea about this?

Hi @sahil1610,

Yesterday I found out that even if in the node it shows enablePassThrough=true when you pass SE_OPTS=-enablePassThrough false, the setting works. So please try it like that:

# To execute this docker-compose yml file use docker-compose -f <file_name> up
# Add the "-d" flag at the end for deattached execution
version: '2'
services:
  firefox:
    image: selenium/node-firefox:3.8.1-dubnium
    volumes:
      - /dev/shm:/dev/shm
    depends_on:
      - hub
    environment:
      - HUB_HOST=hub
      - no_proxy=localhost
      - TZ=Europe/London
      - SE_OPTS=-enablePassThrough false

  chrome:
    image: selenium/node-chrome:3.8.1-dubnium
    volumes:
      - /dev/shm:/dev/shm
    depends_on:
      - hub
    environment:
      - HUB_HOST=hub
      - no_proxy=localhost
      - TZ=Europe/London
      - SE_OPTS=-enablePassThrough false

  hub:
    image: selenium/hub:3.8.1-dubnium
    ports:
      - "4444:4444"
    environment:
      - SE_OPTS=-enablePassThrough false

I also saw your comment in SeleniumHQ/selenium#4665, so if after trying again, you still have the issue. I'd recommend open an issue in the main Selenium repo with a clear way to reproduce the problem.

Regarding docker-selenium, I think it is clear that it is not an issue of the images. I'll leave this issue open for a couple of days in case you have more feedback, and after that I'll go ahead and close it.
