Like a normal grid when we configure the Selenium grid with the Docker we have to install the hub and browser nodes into our Docker container and later, we can start the hub and nodes from that Docker container. In this tutorial, we are going to use Docker for software testing and software automation. We have completed all the steps and you can run your test now. Selenium grid helps to master the computer (hub) to distributed test cases among the slave machines (nodes). This branch Selenium WebDriver and TestNG based test cases. It is possible to record your tests running in containers by using the selenium/video:ffmpeg-4.3.1-20201208 Here I have used two nodes only (chrome node and Firefox node).

After downloading all the images into your container you can check it using the below command. Now by simply executing docker-compose up -d from the directory where the docker-compose.yaml was created, we’ve started up two containers: one hub and one node with Chrome. This window will provide you with all the information about the image (Selenium hub image) and will give you all the commands relevant to that image (Selenium hub image). Split-screen video. and it retries up to 5 times until the container is marked as unhealthy. I do also have the same issue. 2 Hours. Were you able to get the images for Windows Container , if yes could you please help me here ! idea is to have the Hub in one virtual machine, and each of the Nodes in separate and more powerful We use the Selenium grid under such occasions. You can verify whether Selenium hub has started or not by checking the following link in your browser: http://192.168.99.100:4444/grid/console, Here in this image 192.168.99.100 is your IP address.
