7 SLE Micro #
See SLE Micro official documentation
SUSE Linux Enterprise Micro is a lightweight and secure operating system for the edge. It merges the enterprise-hardened components of SUSE Linux Enterprise with the features that developers want in a modern, immutable operating system. As a result, you get a reliable infrastructure platform with best-in-class compliance that is also simple to use.
7.1 How does SUSE Edge use SLE Micro? #
We use SLE Micro as the base operating system for our platform stack. This provides us with a secure, stable and minimal base for building upon.
SLE Micro is unique in its use of file system (Btrfs) snapshots to allow for easy rollbacks in case something goes wrong with an upgrade. This allows for secure remote upgrades for the entire platform even without physical access in case of issues.
7.2 Best practices #
7.2.1 Installation media #
SUSE Edge uses the Edge Image Builder (Chapter 9, Edge Image Builder) to preconfigure the SLE Micro self-install installation image.
7.2.2 Local administration #
SLE Micro comes with Cockpit to allow the local management of the host through a Web application.
This service is disabled by default but can be started by enabling the systemd service cockpit.socket.
7.3 Known issues #
There is no desktop environment available in SLE Micro at the moment but a containerized solution is in development.
