[🐛 Bug]: Grid can't create a session in Dynamic mode

[ekadov]

What happened?

Selenium Grid has been installed on a separate machine via docker-compose.
The node is created, I see it in log.
UI works and the node is visible there.
When I try to start a Selenium session from my Java code, it gives SessionNotCreatedException.

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

docker-compose.yml

Hi.
Can anybody help with the issue?
I'll be really appreciated)

[pietrygamat]

It looks like the problem described in this section or README:

/opt/selenium/config.toml is the default path for the config file in all images. Once volumes config is shared to node browser containers, its config.toml could be overwritten by node-docker container config file.

In this case, mount your config.toml file to /opt/selenium/docker.toml in node-docker container. And set the environment variable SE_NODE_DOCKER_CONFIG_FILENAME=docker.toml to specify that config file name for the startup script.

services:
  node-docker:
    image: selenium/node-docker:4.30.0-20250323
    volumes:
      - ./assets:/opt/selenium/assets
      - ./config.toml:/opt/selenium/docker.toml
      - /var/run/docker.sock:/var/run/docker.sock
    depends_on:
      - selenium-hub
    environment:
      - SE_EVENT_BUS_HOST=selenium-hub
      - SE_NODE_DOCKER_CONFIG_FILENAME=docker.toml
