On Atomic Host, yum is not used to install software. Anything which is not in the base image needs to be deployed as container. That includes not just web applications or databases but system tools and daemons as well.
When we have such container / image, it is possible to deploy it on non-Atomic installation as well, taking advantage of the atomic command which simplifies the installation and configuration using metadata from the image. It is even possible to go back and forth between containerized and non-containerized daemon.
We will share our experience preparing SSSD for Atomic Host and how it can be tested and used in non-Atomic environment.
