Selenoid-UI VNC/logs disconnected in linux environment (works in MacOS)

[Minion0313]

Hi i am using selenoid and selenoid ui in docker for running selenoium tests
everything works perfectly in Mac os... i am able to see my test executions on the selenoid UI
But the same set up does not work on the linux (My office laptop)
dont know what is the issue
getting vnc disconnected the set up is all same is mac and linux except the difference is that mac is personal system and linux is my office laptop
Please help me resolve the issue
thanks in advance

@Minion0313 take a look at browser images you are using. They should have vnc in image name. If that does not help - please take a look at browser console images.

[Minion0313]

@vania-pooh Hi thank you for the response
Initially when i installed it had vnc chrome browser
but when i deleted the cm(configuration manager) and re-installed again i am getting only these below images

Even though VNC image is not there, i am able to see my tests running on selenoid ui (this is in my personal mac)
But i dont see them running in my Linux my office laptop ( getting vnc disconncted)

and one curious question why i am not getting all the omages which i used to previously the along with vnc now ?

thanks in advance
Response is much appreciated

@Minion0313 take a look at browser images you are using. They should have vnc in image name. If that does not help - please take a look at browser console images.

How can i look at the browser console images???

[Minion0313]

@vania-pooh I updated my browers.json file and reloaded selenoid
still i am getting the same issue

This is only happening in my office laptop --- This is a linux box (Docker is installed in this linux machine)
It works perfectly well in my personal laptop ---This is a mac

[vania-pooh]

@Minion0313 console messages are usually available in browser developer toolbar. There is a section called Console there. Currently both vnc and non-vnc images contain VNC server. Previously that was not the case.

@Minion0313 It would be helpful if you could provide us selenoid and selenoid-ui logs when this disconnect happens.

[Minion0313]

@lanwen @vania-pooh
hi thank you for the response
i was not able to resolve the issue yet and here are the logs when i am running the tests, this is what it is showing on the selenoid-ui

Please let me know how could i resolve this issue?
Thanks in advance

[lanwen]

@Minion0313 thanks for sharing! I would ask you next time just copy the output and put it here as a text :) and don't forget to edit internal hosts and replace it with something like "our.company.host.com" (literally), so no internal infrastructure is exposed.

As I can see, selenoid is returning Forbidden status code - do you have any kind of auth before selenoid?

[Minion0313]

@lanwen sure lanwen i will do that , from next time
i did not do anything in particular
when i installed docker i did set up proxy thing in the config file
and also when i pull the selenoid ui image with cm command it wouldn't link properly so i had to remove the image and pull it manually and link it using the below command

docker run -d --name selenoid-ui --link selenoid -p 8080:8080 aerokube/selenoid-ui --selenoid-uri http://myhostname:4444
then only it would be properly connected

[lanwen]

@Minion0313 you then trying to reach wrong host - for the selenoid-ui selenoid-uri should be http://selenoid:4444 can you try that?

What's the issue with cm? Can I kindly ask you to report that to appropriate repo?

do u mean something linke thsi

docker run -d --name selenoid-ui --link selenoid -p 8080:8080 aerokube/selenoid-ui http://selenoid:4444 http://myhostname:4444

[Minion0313]

@lanwen so the issue with cm i am facing is, when i do
./cm start selenoid-ui
it is no automatically linking the selenoid to selenoid ui port
so i had to giv ethat additional command

[lanwen]

Not exactly - selenoid-ui doesn't care about your host.
So as stated in docs it should be

docker run -d --name selenoid-ui -p 8080:8080 aerokube/selenoid-ui --link selenoid --selenoid-uri http://selenoid:4444

[Minion0313]

Not exactly - selenoid-ui doesn't care about your host.
So as stated in docs it should be

docker run -d --name selenoid-ui -p 8080:8080 aerokube/selenoid-ui --link selenoid --selenoid-uri http://selenoid:4444

sorry for asking it again in this url "http://selenoid:4444" selenoid is the host where i am pointing to i mean is it like
ex if selenoid url is http://myhostname:4444
in the url forthe command it should be myhostname or selenoid?
because this is the url i am using to access selenoid http://myhostname:4444 or any status http://myhostname:4444/status or i am able to see when my tests run the session is created in the selenoid ui in http://myhostname:8080(with vnc disconnected issue)

[Minion0313]

I am not able to link it using the above command , i am anot able to access selenoid ui

[lanwen]

Just copy as is. selenoid is the host name for the container, not for you.

[lanwen]

sorry, my bad

docker run -d --name selenoid-ui -p 8080:8080 --link selenoid aerokube/selenoid-ui --selenoid-uri http://selenoid:4444

misplaced link arg

[Minion0313]

Just copy as is. selenoid is the host name for the container, not for you.

thank u for the reply, so what will be the url for accessing selenoid ui?
will that be the same i.e http://myhostname:8080?
correct me if i am wrong

[Minion0313]

@lanwen thank u for ur patience

[Minion0313]

@lanwen corrected and gave the above command

this is what it shows

[lanwen]

@Minion0313 please always provide all available logs.
Url for your selenoid-ui access wouldn't change.

[Minion0313]

@lanwen sorry this is what it shows

Ok, lets get back to the beginning.
Please kill and remove all containers for selenoid and selenoid-ui
then run cm commands as stated in the manual
then if it still shows this picture, provide all the outputs of the commands, docker ls, and docker inspect for the selenoid-ui

[Minion0313]

@lanwen before using the command which u have given i was using this command

docker run -d --name selenoid-ui -p 8080:8080 --link selenoid aerokube/selenoid-ui --selenoid-uri http://hostname:4444

i was atleast able to see the session created
now i am not able to see any session also

[Minion0313]

Ok, lets get back to the beginning.
Please kill and remove all containers for selenoid and selenoid-ui
then run cm commands as stated in the manual

Now you can run Selenoid with cm:
    ./cm selenoid start --vnc

[lanwen]

@Minion0313 hey, thx a lot, can you elaborate on how do you know its not linking automatically?

Selenoid-ui says its Up 21 seconds (healthy) which exactly means everything was linked fine

I mean on the actual UI it was not Connected like showing unknown error

[lanwen]

@Minion0313 okay, now I need docker logs for selenoid and selenoid-ui, as well as curl results for the /status endpoint of selenoid (right after you've done with cm)

@lanwen dev console status

[lanwen]

@Minion0313 thank you a lot, wondering why selenoid-ui gets html instead of json as a response for status.

You greatly could help to identify the issue if would launch ubuntu container same way linked to a selenoid and launch curl for the http://selenoid/status (basically repeat what selenoid-ui) is doing.

I would try to reproduce that on my side in a few days.

Thank's a lot, appreciate your help in investigations

[Minion0313]

@lanwen thank u for the help how could i fix the actual issue now

[lanwen]

@Minion0313 that still not clear for me, that's why I need further assistance from your side
