Containers on It's a Binary World 2.0

SELinux and Podman

Last time I messed around with Podman, I finally got things working and had what I think was a pretty good understanding of how to go forward. But in order to get things working, I’d had to turn off SELinux. Now it was time to see what I had to do to make Podman work with SELinux. I’ve got some ideas based on some Googling and might also need to try a program called udica to create the right contexts.

Like these random container names that podman generated:

# podman ps
 CONTAINER ID  IMAGE                               COMMAND               CREATED        STATUS            PORTS                 NAMES

Makes me think perhaps there should be a list of adjectives and names that shouldn’t go together?

Another piece falls into place for Docker

Yesterday I was at a conference dedicated to DevOps and so Red Hat and Google were there to talk about containers, especially Docker and Kubernetes. While summarizing it to some of my employees today, I was asked about what I see as the benefits of Docker containers relative to Virtual Machines. I mentioned that one of the great things is that Docker containers are immutable. All of your data’s actually written to a folder that’s essentially mounted in the container.
