Does anyone remember the 1999 science fiction action movie, The Matrix?
Well, what about retrieving the mystery and imagination? Interested?
Let's create a container simulating Neo's machine. I'm using Fedora, so if you're not, adjust your actions accordingly.
First, you have to download a package from the Fedora repository and extract the RPM file:
$ wget https://kojipkgs.fedoraproject.org//packages/cmatrix/1.2a/4.fc30/x86_64/cmatrix-1.2a-4.fc30.x86_64.rpm
$ rpm2cpio cmatrix-1.2a-4.fc30.x86_64.rpm | cpio -id
Then you pull the Red Hat Enterprise Linux 8 Universal Base Image and create the new Matrix container:
$ podman pull registry.access.redhat.com/ubi8/ubi
$ podman run --name matrix -it registry.access.redhat.com/ubi8/ubi /usr/bin/bash
# exit
Now copy the binary into the exited container, and then start and attach the container:
$ podman cp usr/bin/cmatrix matrix:/usr/bin/matrix
$ podman start matrix
$ podman attach matrix
Start the animation : # matrix
Show usage options : # matrix -h
Stop the animation : # q
Leave the container : # exit
Cool, isn't it? The same feature (running rootless podman) will be possible on RHEL soon.
