Hi, env var SE_BIND_HOST is represent for --bind-host

[edison12a]

@VietND96
Thanks for sharing that but it does not solve the error.

The error implies that I have specified "SE_BIND_HOST" before but as you can see, its not part of my env variables.

[VietND96]

docker-selenium/Hub/start-selenium-grid-hub.sh

Line 148 in da17d89

--bind-host ${SE_BIND_HOST} \

Due to --binding-host explicitly set in command to start Hub, so the script checking with SE_OPTS could not detect it, that is reason CLI options raise error.

[edison12a]

Thanks @VietND96.

Could we make it so that if the user redefines a variable it will overwrite any defaults that the system is trying to set?

The current error message seems to imply that the user is specifying the variable more than one time.

I just added a change #2451. Will deploy a preview image for your fast trial and feedback
Regarding issue #2447, I am still checking. It seems someone assigns the arbitrary address. However, internal components could not communicate with each other by using that host, the inside container could not reach the DNS

[edison12a]

Thanks for your attention to this issue @VietND96 . I look forward to testing the preview image.

[VietND96]

It is available, update image tag to nightly, you can get it (e.g selenium/hub:nightly). It is the same for nodes images.

[VietND96]

This is fixed in #2451
