CoreOS, or How I Learned to Stop Worrying and Love SystemdRichard Lister
Ric Lister presents patterns for running Docker in production on CoreOS, including a simple homogeneous operations cluster where sidekick units announce services in etcd and a reverse proxy discovers them, an etcd and workers pattern for low-traffic sites behind a load balancer, and an immutable servers pattern without etcd for high-traffic microservices with strict change control. He also discusses logging to ship container output off hosts, various monitoring options, alternative operating systems like RancherOS and Atomic, and scheduler options like Kubernetes, Mesos, and Deis.
QEMU is an emulator that uses dynamic translation to emulate one instruction set architecture (ISA) on another host ISA. It translates guest instructions to an intermediate representation (TCG IR) code, and then compiles the IR code to native host instructions. QEMU employs techniques like translation block caching and chaining to improve the performance of dynamic translation. It also uses helper functions to offload complex operations during translation to improve efficiency.
This document discusses Linux containers and PostgreSQL in Docker containers. It begins with an overview of containers, their advantages and disadvantages compared to virtual machines. It then discusses different implementations of containers like LXC and systemd-nspawn. A large portion of the document is dedicated to Docker containers - how to install, use images and volumes, and common commands. It concludes with best practices for running PostgreSQL in Docker containers, including mounting data volumes, linking containers, checking stats and processes.
This document provides instructions on how to install a virtual machine. It begins by introducing virtual machines and their documentation. It then provides steps to install the JDK, RPM packages, and create a virtual machine host. These steps include installing KVM, QEMU, libvirt, configuring networking, and starting the libvirt daemon. The document then discusses expanding disk capacity by adding a new disk, partitioning it, and formatting the new partition. Finally, it outlines creating a load balancer and nodes by defining virtual machine configurations.
The document discusses building software for embedded systems across different architectures using QEMU. It describes native building versus cross building, and compares building directly on a system emulator versus Scratchbox. It proposes that a simpler approach is to use just the user mode of QEMU, along with chroot and binfmt_misc. An example is given of setting up a basic ARM chroot environment and building software faster using user mode QEMU instead of a full system emulator. Issues like mounting proc and networking are also addressed.
Systemd provides a more modular approach to system initialization and service management compared to SysVinit and Upstart. With systemd, various system initialization tasks and services are defined as independent "units" that have dependencies and startup ordering defined through configuration files. At boot, systemd analyzes the dependencies between units and starts them in parallel where possible to reduce startup time. It provides standardized methods for process supervision and resource management of services.
This document provides instructions for using Vagrant with VirtualBox to install and configure a virtual machine image.

LXC (Linux Containers) provides operating-system-level virtualization without the overhead of full virtualization. It isolates processes into containers using kernel namespaces and control groups. Containers can be limited in their CPU, memory, storage, and network usage. Common commands like lxc-start are used to deploy whole operating systems within containers. LXC provides many of the benefits of virtualization with less overhead since it leverages existing Linux kernel features rather than requiring a separate kernel like traditional virtualization.
While probably the most prominent, Docker is not the only tool for building and managing containers. Originally meant to be a "chroot on steroids" to help debug systemd, systemd-nspawn provides a fairly uncomplicated approach to work with containers. Being part of systemd, it is available on most recent distributions out-of-the-box and requires no additional dependencies.
This deck will introduce a few concepts involved in containers and will guide you through the steps of building a container from scratch. The payload will be a simple service, which will be automatically activated by systemd when the first request arrives.
Containerization is more than the new Virtualization: enabling separation of ...Jérôme Petazzoni
Docker offers a new, lightweight approach to application
portability. Applications are shipped using a common container format,
and managed with a high-level API. Their processes run within isolated
namespaces which abstract the operating environment, independently of
the distribution, versions, network setup, and other details of this
environment.
This "containerization" has often been nicknamed "the new
virtualization". But containers are more than lightweight virtual
machines. Beyond their smaller footprint, shorter boot times, and
higher consolidation factors, they also bring a lot of new features
and use cases which were not possible with classical virtual machines.
We will focus on one of those features: separation of operational
concerns. Specifically, we will demonstrate how some fundamental tasks
like logging, remote access, backups, and troubleshooting can be
entirely decoupled from the deployment of applications and
services. This decoupling results in independent, smaller, simpler
moving parts; just like microservice architectures break down large
monolithic apps in more manageable components.
Kdump and the kernel crash dump analysisBuland Singh
Kdump is a kernel crash dumping mechanism that uses kexec to load a separate crash kernel to capture a kernel memory dump (vmcore file) when the primary kernel crashes. It can be configured to dump the vmcore file to local storage or over the network. Testing involves triggering a kernel panic using SysRq keys which causes the crash kernel to load and dump diagnostic information to the configured target path for analysis.
This document provides guidance on setting up a minimal OpenStack cloud in one's basement for learning and experimenting purposes. It recommends starting with only the core services like Nova, Glance, and Keystone. Example steps are given to install OpenStack on a single node, create a security group to allow SSH, boot an Ubuntu image as a test server, and connect via SSH. Advanced networking with Neutron is not required initially. The document also outlines some additional OpenStack services that can be added later to expand the cloud once the core is established.
A quick introduction to OpenVZ, a virtualization platform for Linux that works like FreeBSD jails - it segments a system into different partitions, all running LInux. Each virtual system, container, can run different Linux distributions.
An overview of OpenVZ virtualization technologyOpenVZ
OpenVZ is an OS-level virtualization technology that partitions a physical server into multiple isolated virtual environments called containers. It provides strong isolation between containers and allows them to independently run their own services and applications. OpenVZ offers benefits like high density, native performance, dynamic resource allocation and easier management compared to other virtualization methods. It has been widely adopted for server consolidation, hosting, development and testing, and other use cases.
Anatomy of a Container: Namespaces, cgroups & Some Filesystem Magic - LinuxConJérôme Petazzoni
Containers are everywhere. But what exactly is a container? What are they made from? What's the difference between LXC, butts-nspawn, Docker, and the other container systems out there? And why should we bother about specific filesystems?
In this talk, Jérôme will show the individual roles and behaviors of the components making up a container: namespaces, control groups, and copy-on-write systems. Then, he will use them to assemble a container from scratch, and highlight the differences (and likelinesses) with existing container systems.
The document discusses using netlink and netlink families to enable communication between the kernel and user space processes. Netlink allows a more flexible alternative to ioctl calls by providing a socket-based interface for exchanging information. Various netlink families exist for communicating with different kernel modules, including NETLINK_ROUTE for routing functions. The document then discusses using netlink and the arpd tool to dynamically update ARP and bridge forwarding database tables in response to layer 2 and layer 3 miss events. This allows maintaining overlay networks by handling ARP requests between network namespaces.
Cgroups, namespaces, and beyond: what are containers made from? (DockerCon Eu...Jérôme Petazzoni
Linux containers are different from Solaris Zones or BSD Jails: they use discrete kernel features like cgroups, namespaces, SELinux, and more. We will describe those mechanisms in depth, as well as demo how to put them together to produce a container. We will also highlight how different container runtimes compare to each other.
This talk was delivered at DockerCon Europe 2015 in Barcelona.
QEMU is an open source machine emulator and virtualizer that can emulate various CPU architectures like x86, PowerPC, ARM, MIPS and SPARC. This document discusses extending QEMU to add support for a new I2C accelerometer hardware and simulating it in QEMU. It describes registering a new device type in QEMU to represent the accelerometer, implementing read/write callbacks to emulate the device behavior, and testing it works with a simple application both in QEMU and on a real Raspberry Pi board.
This document discusses using Btrfs and Snapper to enable full system rollbacks in Linux. It describes how snapshots are automatically created to capture the state of the system before changes. Using Snapper, administrators can rollback the entire system to a previous snapshot to undo changes or revert to a known good state. The document provides examples of rolling back packages, kernels and system configuration changes while ensuring system integrity and compliance.
This document describes setting up a high availability system using two Debian GNU/Linux virtual servers. Distributed Replicated Block Device (DRBD) will be used for data replication between the servers. Heartbeat will monitor the servers and ensure services are running on the active server. Wordpress will be installed to demonstrate that data entered on one server is immediately replicated to the other. Network, storage, and configuration details are provided to set up DRBD and Heartbeat to achieve high availability.
The document provides troubleshooting steps for resolving common problems during the installation of virtual machines. It describes solutions for errors related to mounting an NFS share, starting a domain, permissions issues preventing log files from being read, and network interfaces having duplicate MAC addresses. The solutions include installing NFS utilities, editing the /etc/hosts file, changing file ownership and permissions, restarting domains and networks, and checking firewall and Apache configurations.
