Quick Look at Cockpit for Linux server management


Cockpit is a service for Linux that provides a web-based interface for managing and monitoring hosts. It can be deployed in any size organization, even a small office, and it’s a great way for home users to maintain the family IT infrastructure. I use it to manage and monitor all of the computers in my house—including Raspberry Pi. Cockpit is a free and open source software project released under the LGPL v2.1+. It is sponsored by Red Hat and included in Red Hat Enterprise Linux as the RHEL Web Console.

Set up a self-sustained set of basic Linux servers with nothing more than a system with virtualization software, a CentOS ISO, and about an hour of your time.

Good article that serves as a reminder just how easy it has become to work with Linux. Even though the article talks about CentOS the same strategy would work with Ubuntu, Debian, or just about any other flavor of Linux.

Podman and user namespaces: A marriage made in heaven | Opensource.com

User namespace allows you to specify a user identifier (UID) and group identifier (GID) mapping to run your containers. This means you can run as UID 0 inside the container and UID 100000 outside the container. If your container processes escape the container, the kernel will treat them as UID 100000. Not only that, but any file object owned by a UID that isn’t mapped into the user namespace will be treated as owned by “nobody” (65534, kernel.overflowuid), and the container process will not be allowed access unless the object is accessible by “other” (world readable/writable).
