Can't enable DEBUG logging in Selenium Docker

[Alexey Pavlunin]

Hello. I faced some strange bugs during tests in Selenium running in Docker. I tried to enable debug logging in containers, but they doesn't start normally after I changed docker-compose-v3.yml. Here's part of my yaml:

services:

  chrome:

    image: docker-proxy.nexus.am.int/selenium/node-chrome:4.0.0

    shm_size: 2gb

    depends_on:

      - selenium-hub

    environment:

      - SE_EVENT_BUS_HOST=selenium-hub

      - SE_EVENT_BUS_PUBLISH_PORT=4442

      - SE_EVENT_BUS_SUBSCRIBE_PORT=4443

      - SE_NODE_GRID_URL=http://localhost:4444

    ports:

      - "6900:5900"

Then I added string SE_OPTS="--log-level FINE" to environment section in compose.yml as said in docs

But after start chrome container is failing with error: Was passed main parameter '"--log-level' but no main parameter was defined in your arg class

I tried different combination of parameters, but non of them worked. Only when I changed it to SE_NODE_OPTS="--log-level FINE" container started successfully.

But there are no DEBUG messages in the log output, only INFO level. What should I do to get DEBUG messages?

And is there a way to enable it for selenium hub container?
