Need Info : Running docker in cloud with Selenium Grid - which is best service ?

[Vikram]

Hi All,

Is there any cost effective way of running Selenium grid + Docker in cloud ? Which is best service for this ?

Main purpose is any developer should be able to run automation suite on her/his branch

Thanks in advance.

I've found it very easy to run Selenium Grid via an EC2 instance in Amazon's AWS.  I use docker-compose to manage the containers, which really simplifies things.  There is an existing Selenium Docker project:

https://github.com/SeleniumHQ/docker-selenium

...so you don't have to create your own images.

This blog post will give you an idea of what's involved (you can ignore the part about building your own images if you use the selenium-docker images):

Hi Jeff,

Here is some update with blocking issue


Earlier I had docker setup on MAC mini and everything works perfectly.

Now I'm trying to replicate same setup on Linux VM ( Azure cloud )  + Docker ;  but getting below error and all the test cases are failing.

java.awt.HeadlessException:
No X11 DISPLAY variable was set, but this program performed an operation which requires it.


I have installed xvbf , chrome browser and chrome driver successfully on Linux VM. Please let me know if you had encountered this issue earlier

Thanks & Regards,
Vikram

Vikram, I have not run into that particular error before, and if you're using images from the docker-selenium project, it should not be an issue, since xvfb is built in; see for example:

https://github.com/SeleniumHQ/docker-selenium/blob/master/NodeBase/Dockerfile#L35

I would suggest verifying that the Selenium Grid hub is definitely up-and-running as expected, using a URL like this:

http://<hostname>:4444/grid/console

If you see the Grid console at the URL, along with whatever browser nodes you chose to start, then you should be in business.  If you don't see the Grid console at that URL, then something has happened with the hub startup, and I'd suggest looking at the Selenium logs at that point to try and determine the source of the problem.

Hi Jeff,

Thanks for reply.

I could get the issue resolved at last , details here https://github.com/serenity-bdd/serenity-core/issues/353

Here is git repo if somebody wants to try it out with Docker setup

https://github.com/vikramvi/junit-webtests-parallel-grid-docker-jenkins-debug/tree/master/junit-webtests


Now the next challenge is to integrate this whole setup with Jenkins , so that anyone within company network can run in cloud VM.

I'll update once I get it working on Azure Linux VM

Vikram

Need help for below

1. I have installed selenium grid plugin in the Jenkins. Have created a sample node. Question - how to tun tests on the node created ?

2. Do I need to create seperate VM in azure and install selenium Hq seperately there?

3. If yes to the 2nd question, How to direct the first instance of Jenkins to talk to selenium installed in seperate VM ?
