[🐛 Bug]: I can't mount the volume in dynamic gird for browser node

[barkep]

What happened?

I am setting up an environment for selenium grid. I want to use selenium dynamic grid.

My test case is loading an attachment on a web page.

I tried to attach the volume in docker compose, but the attachments are only visible in node docker. Not in dynamically created browser containers.

I also tried using the configuration in config.toml and it still doesn't work:

[node] max-sessions = 2 [docker] configs = [ "selenium/standalone-chrome:4.18.0", "{"browserName": "chrome"}" ] url = "http://127.0.0.1:2375" video-image = "selenium/video:ffmpeg-6.1-20231219" volumes = ["path_on_disk:/opt/selenium/attachments"]

Command used to start Selenium Grid with Docker (or Kubernetes)

version: "3"
services:
  node-docker:
    image: selenium/node-docker:4.18.0
    volumes:
      - ./assets:/opt/selenium/assets
      - ./attachments:/opt/selenium/attachments
      - ./config.toml:/opt/bin/config.toml
      - /var/run/docker.sock:/var/run/docker.sock
    depends_on:
      - selenium-hub
    environment:
      - SE_EVENT_BUS_HOST=selenium-hub
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443
      - SE_VNC_NO_PASSWORD=1

  selenium-hub:
    image: selenium/hub:4.18.0
    container_name: selenium-hub
    ports:
      - "4442:4442"
      - "4443:4443"
      - "4444:4444"

Looks like this is the same as feat request https://github.com/SeleniumHQ/docker-selenium/issues/1642 @diemol, can you confirm?

[diemol]

Yes. It is the same.

Why do you need this?

I've already tried setting "devices" and "volumes" in toml and it doesn't work. Maybe I'm configuring something wrong. Below is an example of the code from the test and the stacktrace I get.

I don't know if you had a look at the linked issue, but it is not possible to mount volumes to the child containers.

I would like to better understand your use case. There is probably an alternative way of doing it.

This change is part of the upstream repo: https://github.com/SeleniumHQ/selenium/pull/13804, a trick can help in this case, based on a generic way to share the node-docker container HostConfig with the browser containers is dynamically provisioned, and the config key Binds is used to copy volume mappings of node-docker to browser containers inside.

The configuration looks like

config.toml

[node]
max-sessions = 2

[docker]
configs = [
"selenium/standalone-chrome:nightly", '{"browserName": "chrome"}'
]
url = "http://127.0.0.1:2375/"
video-image = "selenium/video:ffmpeg-7.0-nightly"

host-config-keys = ["Binds"]

docker-compose.yml

version: "3"
services:
  node-docker:
    image: selenium/node-docker:nightly
    volumes:
      - ./assets:/opt/selenium/assets
      - ./attachments:/opt/selenium/attachments
      - ./config.toml:/opt/bin/config.toml
      - /var/run/docker.sock:/var/run/docker.sock
    depends_on:
      - selenium-hub
    environment:
      - SE_EVENT_BUS_HOST=selenium-hub
      - SE_EVENT_BUS_PUBLISH_PORT=4442
      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443
      - SE_VNC_NO_PASSWORD=1

  selenium-hub:
    image: selenium/hub:nightly
    container_name: selenium-hub
    ports:
      - "4442:4442"
      - "4443:4443"
      - "4444:4444"

With that config, host path ./attachments can retrieve files from path /opt/selenium/attachments in container standalone-chrome or any browser containers provisioned.

With that config, host path ./attachments can retrieve files from path /opt/selenium/attachments in container standalone-chrome or any browser containers provisioned.

When i use this configuration i get a WebDriverCurlException

Curl error thrown for http POST to /session with params: {"capabilities":{"firstMatch":[{"browserName":"chrome","goog:chromeOptions":{"args":["--window-size=2560,1440"]}}]},"desiredCapabilities":{"browserName":"chrome","platform":"ANY","goog:chromeOptions":{"prefs":{"download.prompt_for_download":false,"download.default_directory":"C:\\tmp\\","profile.default_content_setting_values.automatic_downloads":1},"args":["--window-size=2560,1440"]}}}

Prior to that it usually failed after 47 secs., because it can't find the file it's looking for. Desired path is => /home/seluser/ImportDateinenSeleniumGrid/ I tried it with external volume and with local link Here is my docker compose file and the config.toml:

docker-compose.yml

version: "3.7"

services:
  chrome:
    image: selenium/node-docker:latest
    volumes:
      - "/root/docker/ImportDateinenSeleniumGrid:/home/seluser/ImportDateinenSeleniumGrid"
      - sel-imp-dat:/home/seluser/

      - "4444:4444"
volumes:
  sel-imp-dat:
    external: true

config.toml

[node]
max-sessions = 4

[docker]
configs = [
"selenium/standalone-chrome:nightly", '{"browserName": "chrome"}'
]
url = "http://127.0.0.1:2375/"

Also interesting is => I started only one Test and there are 2 nodes created At first is was only one but after 3-4 mins there is another instance created
