Containerising your applications with Docker gets more and more attraction. While managing your Docker containers on your developer machine or on a single server is not a big hassle, it can get uncomfortable very quickly when you want to deploy your containers in a cluster, no matter if in the cloud or on premises. How do you provide high availability, scaling and monitoring? Fortunately there is a rapidly growing ecosystem around docker, and there are tools available which support you with this. In this session I want to introduce you to Kubernetes, the Docker orchestration tool started and open sourced by Google. Based on the experience with their data centers, Google uses some interesting declarative concepts like pods, replication controllers and services in Kubernetes, which I will explain to you. While Kubernetes still is a quite young project, it reached its first stable version this summer, thanks to many contributions by Red Hat, Microsoft, IBM and many more.

Google has been running everything in containers for the past 15 years, but how do we orchestrate and manage all those containers? We've built and released the open source Kubernetes (http://kubernetes.io), which is based on years of running containers internally at Google. Join us for an introduction to containers and Kubernetes, followed by a hands-on workshop building and deploying your own Kubernetes cluster with multiple front end, database and caching instances. Docker containers help solve the issue of process-level reproducibility by packaging up your apps and execution environments into a number of containers. But once you have a lot of containers running, you'll need to coordinate them across a cluster of machines while keeping them healthy and making sure they can find each other. This can quickly turn into an unmanageable mess! Wouldn't it be helpful if you could declare what wanted, and then have the cluster assign the resources to get it done and to recover from failures and scale on demand? Kubernetes is here to help! Key takeaways - Gentle introduction into containers: why and how - Learn how Google manages applications using containers - Intro to Kubernetes: managing applications and services - Build and deploy your own multi-tier application using Kubernetes

Incredibly powerful and flexible, Kubernetes role-based access control (RBAC) is an essential tool to effectively manage production clusters. Yet many Ops and DevOps engineers are still facing barriers to efficiently use it at scale. These include a steep learning curve, YAML-based configuration, lack of standardized best practices, and the general complexity of this functionality at large -- it truly can be somewhat overwhelming. During this meetup Oleg, CTO at Kublr, will discuss Kubernetes RBAC concepts and objects. He'll explore different use cases ranging from simple permission management for in-cluster application accounts to integrations with external identity providers for SSO and enterprise user access management. Leveraging the Kublr Platform, Oleg will demonstrate how it simplifies the management of access and RBAC rules in a cloud native environment while staying vendor-independent and compatible with any Kubernetes distribution.

Installing Kubernetes is easy. Ensuring it complies with your organization’s enterprise governance and security requirements isn’t. How do you use the technologies while meeting enterprise security requirements? We'll summarize common prerequisites for running Kubernetes in production, and how to leverage fine-grained controls and separation of responsibilities to meet enterprise governance and security needs. This deck includes basic requirements for audit, security, authentication, authorization, integration with existing identity broker, logging, and monitoring. Additionally, we'll go into whether cloud-hosted Kubernetes cover these requirements, how to integrate a compliant Kubernetes installation with their existing cloud infrastructure and how to handle cross-team communication (network/compute/storage/security). Since on-premise Kubernetes deployments have their challenges, limitations of a bare-metal installation, interactions with vSphere’s API, achieving HA, reliability and disaster recovery, as well as handling OS upgrades, security patches, and Kubernetes upgrades are also considered.

Kubernetes gives developers a platform on which to run images and many configuration objects to control those images, but constructing a cohesive application made up of images and configuration objects is currently a challenge. Reconstructing or sharing that configuration can also be a challenge. This talk will cover the Template feature implemented in OpenShift to simplify the process of defining and repeatably deploying coordinated objects, discuss what is coming to Kubernetes with respect to this capability, and touch on several other existing projects that enable templatizing application definitions.

Whether you work alone or in a team, some sort of source control management is essential to you as a developer for things like keeping a history of your code, dealing with integrating code, managing releases and making your development workflow through different features painless. If you're coming from something like CVS or SVN, the open-source Git version control system will turn what you know of SCM on its head. In this presentation from AnDevCon 2011, EffectiveUI’s Tony Hillerson explains why Git is different, and what that difference means to you as an Android developer.

Presented at All Thing Open RTP Meetup Presented by Brent Laster Abstract: Kubernetes is the leading way to run and manage your containerized workloads across any cloud or on-premises environment. It provides an automated, reliable way to execute the services, deployments, etc. that make up your application. But what happens when running those doesn’t go as you’d expect, or the system isn’t happy with what you’re trying to get to run? How do you figure out what’s going wrong, track down the root causes, figure out a solution, and get things working again? In this hands-on three-hour workshop, we’ll look at some basic and advanced ways to debug problems that you may run into with Kubernetes. You’ll learn techniques from basic ways to zero in on root cause to log analysis to using advanced tools such as creating your own debug containers. Armed with these skills, you’ll be in a position to deal with day-to-day issues with running workloads in Kubernetes and keep them from becoming disruptions and/or show-stoppers.

While etcd was born in the cloud era, it does not really play well in a dynamic environment where nodes come and go and where IP addresses are ephemeral. Moreover, etcd is meant – with its RAFT algorithm at the core – as a consistent key-value store. It rather refuses to form or join a cluster than putting concistency at risk. As a consequence it is very conservative in implementing advanced cluster member management mechanisms – or even heuristics to make the operation of an etcd cluster more comfortable for the admin. The elastic-etcd binary experiments with those advanced member management heuristics. It is meant as a frontend to the etcd binary, applying these heuristics and then creating a matching command line for etcd itself.

We specialize in Psychic Readings, Psychic Love Spells, Binding Love Spells, Obsession Spells, Voodoo Spells, Lottery Spells, Marriage Spells, Black Magic Spells, Palm Readings & much more. 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.

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.
