Lxc- Linux Containers
LXC (Linux Containers) allows multiple isolated Linux systems called containers to run on a single Linux host. Containers offer lightweight virtualization by running applications in isolated processes on the host operating system without needing a hypervisor. This provides better performance than virtual machines and allows containers to be deployed and migrated more easily. While still a newer technology, LXC adoption is growing rapidly due to its benefits for server isolation, workload management, and portability.
Introduction to linux containers
Linux Containers(LXC) allow running multiple isolated Linux instances (containers) on the same host.
Containers share the same kernel with anything else that is running on it, but can be constrained to only use a defined amount of resources such as CPU, memory or I/O.
A container is a way to isolate a group of processes from the others on a running Linux system.
Lxc- Introduction
LXC (Linux Containers) are lightweight virtual machines created using kernel-level virtualization rather than a hypervisor. The document discusses LXC, including that it provides operational system-level virtualization allowing multiple isolated systems to run on a single host. It also covers main LXC implementations like LXC, Docker, and OpenVZ which are written in C or Go and have stable codebases. Basic usage of LXC like creating, starting, and stopping containers is demonstrated.
LXC
This document discusses Linux containers (LXC), which provides operating system-level virtualization. It allows multiple isolated Linux systems to run on a single host. LXC offers advantages like being lightweight, providing comprehensive process and resource isolation, and allowing for rapid deployment. The document outlines basic LXC usage like creating, starting, and stopping containers. It also covers more advanced topics such as unprivileged containers, cloning and snapshots, networking configurations, and example applications for LXC.
Linux containers-namespaces(Dec 2014)
presentation held at SUSE Linux Expert Forum December 2014
Linux container history and Linux namespaces
examples include:
* Move a VPN connection to its own namespace(p 25)
* User namespaces demo(p 28)
see collection of useful articles and advanced container usecases pp 29
LXC NSAttach
The document describes the namespace attachment feature for LXC containers which allows processes to attach to the namespaces of other processes, providing de-isolation between containers and hosts. It specifies how namespace attachment works using the setns() system call and files in the /proc directory, and discusses integrating this feature into the LXC container by modifying its source code and libraries. Use cases where breaking isolation may be acceptable are also outlined.
Namespaces in Linux
This document discusses namespaces in Linux. Namespaces allow containers to have isolated resources like processes, networking, file systems, users and more. Containers share less than virtual machines but provide more isolation than regular processes. Namespaces use the clone system call to create an isolated view of various system resources for a container. Common namespaces include UTS for hostname, IPC for shared memory, PID for process IDs, network, mount and more. Tools like LXC, Docker and systemd-nspawn make it easy to create and manage containers using namespaces and cgroups.
Getting Started With K3S
K3s is a lightweight Kubernetes distribution that is highly available and optimized for resource usage, taking up less than 40MB. Service discovery in K3s allows processes and devices on the network to automatically detect each other using environment variables, DNS, or a Kubernetes service object which provides load balancing and sends traffic only to healthy backends while offering features like session affinity and label selectors.

- Linux kernel versions follow a naming convention and source code can be found at kernel.org
- Kernel source code is installed by extracting tar files and applying patches
- The kernel directory has a hierarchy and is configured, built, and installed
- Kernel modules are installed separately from the kernel
- The kernel lacks features of userspace like memory protection and floating point support due to its low-level nature and process management
Isolating an applications using LXC – Linux Containers
configuring and running an application inside the container. Dockers are built on top of LXC. In Dockers case, its advantage is that its open-source engine can be used to pack, ship, and run any application as a lightweight, portable, self-sufficient LXC container that runs virtually anywhere. It’s a packaging system for applications.
The building blocks of docker.
Docker provides a way to package applications into containers that can be run on any infrastructure. It uses namespaces and cgroups to isolate processes and share resources efficiently. The key components are images which are read-only templates for building containers, registries for storing images, and containers which combine an image with writable layers and metadata to run applications anywhere. Docker uses a client-server architecture with containers built from images and managed through commands to the Docker daemon which handles building, running, and distributing containers.

Mca ii os u-5 unix linux file system
Linux is a free, open-source operating system based on UNIX with a modular kernel. It uses processes, threads, virtual memory, and files systems. Device drivers allow access to hardware via the block I/O system. Interprocess communication includes signals, pipes, shared memory, and semaphores. Security features authentication via PAM and access controls permissions via user and group IDs.
Linux architecture
The document summarizes the architecture of the Linux operating system. It discusses the main components of Linux including the kernel, process management, memory management, file systems, device drivers, network stack, and architecture-dependent code. The kernel is at the core and acts as a resource manager. It uses a monolithic design. Process and memory management are handled via data structures like task_struct and buddy allocation. Virtual memory is implemented using page tables. File systems organize files in a hierarchy with inodes. Device drivers interface with hardware. The network stack follows a layered model. Architecture code is separated by subdirectory.
Realizing Linux Containers (LXC)
Linux containers (LXC) provide operating system-level virtualization using features of the Linux kernel such as cgroups, namespaces, and chroot. This allows for the creation of lightweight isolated environments called containers that share the kernel of the host system. Containers offer many advantages over traditional virtual machines such as near-native performance, flexibility, and lightweight resource usage. The document discusses the key building blocks and technologies that underpin LXC such as cgroups for resource control and namespaces for process isolation. It also covers the benefits of using LXC and how container images are realized on Linux.
Linux architecture
The document summarizes the architecture of the Linux operating system. It discusses that Linux is divided into the kernel space and user space. The kernel is responsible for process management, memory management, file systems, device drivers, and the network stack. It also touches on architecture-dependent code and the components of the Linux system like the kernel, user applications, and system libraries.
Linux internal
The document provides an overview of the key components of the Linux operating system, including:
1) The Linux kernel, which acts as a resource manager for processes, memory, and hardware devices.
