Launching GUI Apps on the Docker Container.
Hello everyone, In this blog, I am going to tell you guys how to launch a GUI application on the Docker Containers.
The Only prerequisite is we should have a Linux OS with Docker installed on it.
To know how to install Docker on the RHEL8 Linux. Click here
So here are some steps:
STEP 1:
Start the docker services and pull CentOS Docker Image from the docker hub.
STEP 2:
Launch the Docker container, but if we launch it with the command docker run -it — name=GUIcont centos:latest , we cannot run the GUI apps. So we have to change the command.
Here comes the interesting thing, the — env flag defines a variable in our container that matches our DISPLAY variable on the host.
STEP 3:
Now we have to Run some GUI application on the container to see if it runs or fails.
For this, we are running the jupyter notebook & the jupyter notebook uses the web browser to run on it. And the web browser is a GUI app.
After running all the above commands the firefox browser will open with the jupyter notebook.
I hope you guys understand how to launch the GUI app on the container.
Thank you guys for reading,
