[🐛 Bug]: selenium/hub:4/4.23/4.32.X and selenium/node-chrome:4/4.23/4.23.X never allow UI Access

[areis422]

What happened?

Launching a pair of containers: 1 x hub, 1 x chrome node, both containers launch successfully, but getting connection refused on tcp/4444 (Chrome/Edge error: ERR_CONNECTION_REFUSED). Rolling back to 4.22.0 works without issue

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

It is due to a clash CLI option --log-level INFO in SE_OPTS and env var SE_LOG_LEVEL. This issue will be fixed in next deployment
In the meantime, you can adjust the command to remove --log-level INFO from SE_OPTS

docker run -d -p 4442-4444:4442-4444 --net "selenium-grid" --shm-size="2g" --cpus=".75"
-v "/var/log/selenium":"/tmp/log" --restart unless-stopped --name "selenium-hub"
-e SE_OPTS="--http-logs true --plain-logs false --structured-logs
true --log-encoding ASCII --tracing true --log /tmp/log/hub.log" "selenium/hub:4";

@VietND96, I also just noticed that the TZ env var isn't being respected either. Command shows "US/Central" but docker inspect still shows utc

[VietND96]

@areis422 as I remember, there is no change on TZ env var. Do you have the last version that worked?

[areis422]

I do not. just something I just noticed during this troubleshooting exercise.

[VietND96]

@areis422, for the timezone, using a valid value from https://en.wikipedia.org/wiki/List_of_tz_database_time_zones#List set to env var TZ, time in container will update accordingly

docker run --rm --entrypoint="date" -e TZ=Asia/Ho_Chi_Minh selenium/node-chromium:latest
