With the announcement of the OCI by Solomon Hykes at last summer's DockerCon, a Docker-contributed reference implementation of the OCI spec, called runC, was born. While some of you may have tried runC or have a history of poking at the OS layer integration library to Linux namespaces, cgroups and the like (known as libcontainer), many of you may not know what runC offers. In this talk Phil Estes, Docker engine maintainer who has also contributed to libcontainer and runC, will show what's possible using runC as a lightweight and fast runtime environment to experiment with lower-level features of the container runtime. Phil will introduce a conversion tool called "riddler", which can inspect and convert container configurations from Docker into the proper OCI configuration bundle for easy conversion between the two environments. He'll also demonstrate how to make custom configurations for trying out security features like user namespaces and seccomp profiles.

Nicola Paolucci, Atlassian Containers hit the collective developer mind with great force the past two years and created a space of fervent innovation. Now work is moving towards orchestration. In this session we'll cover an overview of the container orchestration landscape, give an introduction to Docker's own tools - machine, swarm and compose - and show a (semi)live demo of how they work in practice.

OSv is the revolutionary new open source technology that combines the power of virtualization and micro-services architecture. This combination allows unmodified applications deployed in a virtualized environment to outperform bare-metal deployments. Yes. You've heard it right: for the first time ever we can stop asking the question of how much performance would I lose if I virtualize. OSv lets you ask a different question: how much would my application gain in performance if I virtualize it. This talk will start by looking into the architecture of OSv and the kind of optimizations it makes possible for native, unmodified applications. We will then focus on JVM-specific optimizations and specifically on speedups available to big data management distributed applications. Finally, we will look into the relationship between OSv and Docker and how that layering can help make OSv a secret sauce for turbo-charging Cloud Foundry application deployments.

In this deck, I quickly summarize how people have dealt with logging in Docker historically and then describe a comprehensive approach to logging and monitoring in Docker, based on research and customer interviews. While Docker adds a welcome layer of abstraction to the deployment of applications, it also challenges assumptions on how those applications should be managed. I discuss a comprehensive approach for collecting logs and metrics into a centralized platform and dissect the latest additions to Docker itself (log drivers, stats).

OSv is the new open source unikernel technology that combines the power of virtualization and micro-services architecture. This combination allows unmodified applications to be packaged just like Docker containers while at the same time outperform bare-metal deployments. Yes. You've heard it right: for the first time ever we can stop asking the question of how much performance would I lose if I virtualize. OSv lets you ask a different question: how much would my application gain in performance if I virtualize it. This talk will start by looking into the architecture of OSv and the kind of optimizations it makes possible for native, unmodified applications. We will then focus on JVM-specific optimizations and specifically on speedups available to micro-service oriented applications when they are being deployed on OSv.

Virtual machines in the cloud typically run existing general-purpose operating systems such as Linux. We notice that the cloud’s hypervisor already provides some features, such as isolation and hardware abstraction, which are duplicated by traditional operating systems, and that this duplication comes at a cost. We present the design and implementation of OSv, a new guest operating system designed specifically for running a single application on a virtual machine in the cloud. It addresses the duplication issues by using a low-overhead library-OS-like design. It runs existing applications written for Linux, as well as new applications written for OSv. We demonstrate that OSv is able to efficiently run a variety of existing applications. We demonstrate its sub-second boot time, small OS image and how it makes more memory available to the application. For unmodified network-intensive applications, we demonstrate up to 25% increase in throughput and 47% decrease in latency. By using non-POSIX network APIs, we can further improve performance and demonstrate a 290% increase in Memcached throughput.

These slides are from a talk presented at the Docker Athens meetup on Thursday, May 31, 2018. They start by covering the evolution of the Docker engine of 2014/2015 into the separate components of OCI runc, (now) CNCF containerd, and the Docker client and daemon projects. Finally, various use cases for the CNCF containerd "core container runtime" project are detailed, from the Docker engine itself to serverless frameworks like OpenWhisk, to the container runtime interface (CRI) within Kubernetes.

Are you depressed? We perform this come-to-me love spell that works instantly with the aim of bringing back the victim to the person performing the magic. Have you lost your lover? We perform this come-to-me love spell that works instantly with the aim of bringing back the victim to the person performing the magic. Have you lost your lover? Do u need to solve any relationship problem? Contact the powerful spells caster chief kule with love spells that work overnight and love spells that really work. Have you found yourself infatuated with a special someone you think could be the one? Are you looking for a spell to provide them with a nudge in the right direction? Or maybe the spell you cast didn’t achieve the results you were hoping for? Whether you’re new or versed in the ways of spell casting, we’re here to help. Today we’re going to provide you with a detailed guide on the types of love spells to cast. Not only that but there’s something for those who wish to find outside advice from more advanced spell casters. We’re also going to provide you with the top sites available to help you with your dilemma. Let’s begin our journey by educating ourselves on love magic and what a real love caster looks like. Love Magic and Love Casters Love magic made its first appearance back in Ancient Egypt and has been an active practice since. This type of magic is a branch of traditional magic and can be practiced in various ways. Typically the more common use of love magic is through the work of spells, but other methods look like Charms Rituals-LOVE Potions-Dolls and even Amulets If you are interested in becoming a love caster, be prepared for what’s to come. A genuine love caster knows that the art of love casting is no easy feat and shouldn’t be done casually. You should know that not only does it require you to be gifted spiritually, but you must be ready to serve others. Someone who is considered a real love caster has experience in all manner of spells, no matter the difficulty. Training yourself in attraction, commitment, and marriage spells is an excellent place to start. But this by no means will make you a professional. Practice your craft and expand your knowledge; understand that you will possess the ability to help others in time truly. Types of Love Spells What better way to start broadening your experiences with love spells than by learning more about them? These spells work like just about any other spell. Simply apply your intention, use a medium (sigils, mantras, candles, or charm bags), and top it off with establishing the belief that you will receive what you want. So what kind of spells are available and which ones suit your needs the best? Let’s take a look at the many options you have at your disposal.

ADR, or Architecture Decision Record, is a valuable tool in software development for several reasons. It provides a centralized location for documenting and tracking architectural decisions, aiding both current and future team members. ADRs enhance communication among team members by documenting the rationale behind architectural decisions, especially beneficial during onboarding of new team members or when revisiting decisions. They serve as a knowledge base, enabling teams to learn from past decisions and refine their decision-making process. Additionally, ADRs contribute to transparency by helping stakeholders understand the reasons behind specific architectural choices. As with any other tool or process, introducing them into an organization can face several obstacles, and overcoming these challenges is crucial for successful implementation. In this talk I go through some common problems and our way of solving them.
