The term "containers" is heavily overused. Also, depending on the context, it can mean different things to different people. Traditional Linux containers are really just ordinary processes on a Linux system. These groups of processes are isolated from other groups of processes using resource constraints (control groups [cgroups]), Linux security constraints (Unix permissions, capabilities, SELinux, AppArmor, seccomp, etc.), and namespaces (PID, network, mount, etc.)

There's a new script in town that promises to let you convert the installers of various commercial Linux games to Flatpak bundles you can run conternized on a wide range of GNU/Linux distributions.

VIDEO: Linux has run on mainframes for decades. Now IBM and partners are enabling users to access z/OS using a new open-source framework, Zowe.

The tmux utility, a terminal multiplexer, lets you treat your terminal as a multi-paned window into your system. You can arrange the configuration, run different processes in each, and generally make better use of your screen. We introduced some readers to this powerful tool in this earlier article. Here are some tips that will help […]

Part I of this Deep Dive on containers introduces the idea of kernel control groups, or cgroups, and the way you can isolate, limit and monitor selected userspace applications. Here, I dive a bit deeper and focus on the next step of process isolation—that is, through containers, and more specifically, the Linux Containers (LXC) framework.

If you’ve ever worked on a large codebase with a distributed development model, you’ve probably heard people say things like “Sue just sent a patch,” or “Rajiv is checking out the diff.” Maybe those terms were new to you and you wondered what they meant. Open source has had an impact here, as the main development model of large projects from Apache web server to the Linux kernel have been “patch-based” development projects throughout their lifetime. read more

PostgreSQL is an open source RDBMS (Relational DataBase Management System), and with any databases, the need may arise to scale and provide HA (High Availability). A single system providing a service is always a possible single point of failure - and even with virtual systems, there may be a time when you can't add more resources to a single machine to cope with the ever-increasing load. There also may be a need to another copy of the database contents that can be queried for long-running analytics, that are not fit to be run on the highly transaction-intensive production database. This copy could be a simple restore from the most recent backup on another machine, but the data would be outdated as soon as it is restored.
