Docker allows applications to be packaged with their dependencies and libraries into standardized units called containers that can run on any infrastructure regardless of the underlying operating system. Containers isolate applications from each other and the underlying host, providing a lightweight and portable way to deploy software that increases efficiency and reduces costs of development, testing, and operations compared to traditional virtual machines. Docker images containing pre-built application containers can be stored in shared public or private repositories like Docker Hub, enabling applications and their dependencies to be easily distributed, updated, and run anywhere.

Lors de cette présentation, nous allons dans un premier temps rappeler la spécificité de docker par rapport à une VM (PID, cgroups, etc) parler du système de layer et de la différence entre images et instances puis nous présenterons succinctement kubernetes. Ensuite, nous présenterons un processus « standard » de propagation d’une version CI/CD (développement, préproduction, production) à travers les tags docker. Enfin, nous parlerons des différents composants constituant une application docker (base-image, tooling, librairie, code). Une fois cette introduction réalisée, nous parlerons du cycle de vie d’une application à travers ses phases de développement, BAU pour mettre en avant que les failles de sécurité en période de développement sont rapidement corrigées par de nouvelles releases, mais pas nécessairement en BAU où les releases sont plus rares. Nous parlerons des diverses solutions (jfrog Xray, clair, …) pour le suivie des automatique des CVE et l’automatisation des mises à jour. Enfin, nous ferons un bref retour d’expérience pour parler des difficultés rencontrées et des propositions d’organisation mises en oeuvre. Cette présentation bien qu’illustrée par des implémentations techniques est principalement organisationnelle.

Swarm 2 Go - Build A Portable Multi-Arch Data Center with Pi and UP Nodes

Stefan Scherer

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.

A talk given at DevOps Pro Vilnius on March 15, 2018 about container security. In this talk we discussed the core topics around the container ecosystem (host, runtime, image) applicable to both Docker and Kubernetes, as well as discussing usable security/secure by default, and defense in depth principles. Also discussed were security futures like Project Grafeas, libentitlement, LinuxKit concepts, and trusted/untrusted container runtimes in Kubernetes.

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.

You want a man who is honest, hardworking, and loyal – not a complainer or a weakling or a self-centred man. You are a strong, independent, sensual, caring, loving woman. And you don’t think it’s asking too much to want to be with a loving, intelligent man with a good sense of humour and daring, an upright and confident man – who knows who he is. No one wants a chauvinistic and macho man, but you do want someone who will be willing to protect and care for you. Who loves you for you and not some kind of imaginary. You have no doubt that when the right guy appears on your doorstep, you’ll never let him go. But sometimes a man doesn’t realize he has that good woman.
