On the OCF (CZ or RZ), you may install the RealVNC client from your LLNL workstation's software catalog for MacOS or Windows and via the LLNL YUM repository on Linux.

( NOTE You *must* use the RealVNC client to connect.) All users should have accounts available on the czvnc cluster, and RZ and SCF users should also have their accounts active in those respective centers. Connections to LC machines via VNC Viewer persist even if no client is actually viewing it. Once logged into this desktop via RealVNC's VNC Viewer, users are able to open a terminal and ssh to other LC machines. You can also support me by liking and sharing this content.RealVNC is a Virtual Network Computing (VNC) server which provides a securely authenticated and encrypted way for users to create and view a virtual desktop on an LC cluster (czvnc, rzvnc, or scfvnc).

🙌🏼Ĭheck out the video below to learn more about how to execute Selenium tests in Docker and view it in VNC Viewer – Once you will run your tests, you will notice the tests can be viewable in the VNC viewer. Now it's time to run tests in Docker, make sure your tests are pointed to port 4444 as that is what we have set up for our docker container (you can check out my previous post to learn more about that). When prompted for a password, type secret and continue. To do that, open up the RealVNC client and type in the URL - 127.0.0.1:5900, and hit Enter. Now that we have a docker image running mapped to port 5900, we can open that port in VNC viewer.

-p 5900:5900 is the port for your local VNC server mapping to Docker VNC server.

-p 4444:4444 is the port for your local machine mapping to Docker Selenium server port 4444.Let's run the selenium/standalone-chrome-debug image and map the VNC port with it -ĭocker run -d -p 4444:4444 -p 5900:5900 -shm-size=2g selenium/standalone-chrome-debug:3.141.59-20210607 Run Selenium Standalone Debug Docker image Map external VNC port to the Docker VNC port (5900): when you will run the docker image you will need to map the local VNC port to Docker VNC port (5900).Any image that ends with -debug will have a VNC server installed Use Selenium Debug images: to be able to see what's going inside the Docker container, you will need to use an image that has a VNC server installed.Install a VNC client: the one I am using in this tutorial is the RealVNC.But, with the help of the VNC viewer, you get a visual representation of exactly what's going on inside Docker which makes it easier to debug your test issues.

Typically, when tests are being triggered inside Docker container, you are not able to see anything that's happening inside. However, the main reason we want to view tests in VNC viewer is to be able to debug any test issues that are happening inside the Docker. Because I thought the goal is to be able to view the tests running in VNC. Originally, when I was preparing this post, I was going to name the title 'View Selenium Tests in Docker using VNC Viewer'. Why run Selenium tests in Docker using VNC viewer? We will also learn why it's important to run tests through VNC Viewer as well. In this tutorial, we will take a look at how to integrate VNC Viewer with Docker and debug Selenium tests in Docker using VNC Viewer. In the previous post, we learned how to integrate Selenium tests with Docker.
