JavaOne 2016: Kubernetes introduction for Java Developers

This presentation discusses automating the deployment and upgrade of Docker applications with a single click using Rancher Labs' open source container management platform. The platform allows users to build a private container service for deploying containers across multiple hosts with a single click. A demo of the platform's capabilities for simplified deployment and upgrades of Docker applications was provided.

This document provides an introduction to Gitlab CI and continuous integration/continuous delivery (CI/CD) workflows. It discusses DevOps practices and the benefits of Gitlab CI. It then covers how to set up Gitlab runners, write a basic Gitlab CI configuration file, define jobs, stages, variables and environments. The document demonstrates concepts like Docker integration, artifacts, auto and manual deployments, and stopping deployments. It concludes with a live demo of a Gitlab CI configuration.

This document summarizes an agenda for a Basefarm Tech MeetUp on OpenShift. The agenda includes welcome remarks, presentations on DevOps, microservices, containers and OpenShift architecture from Red Hat speakers, and a live demo of a "Safely Agile" application on OpenShift. Basefarm also provides OpenShift installation and operations services to help customers implement and manage OpenShift platforms.

Continuous delivery is a powerful concept, but hard to achieve. One of the challenges is automating the setup of environments and the deployment of the Java EE applications. We have looked at and used quite some tools like for instance Chef, Puppet, Vagrant and Nolio. All tools had one thing in common: we had never used them. Why should we invest time in mastering those tools? There is a perfect alternative in Jenkins, a tool most developers are familiar with. Besides the basic Jenkins buildserver capabilities it offers quite some useful plugins like the Build Pipeline plugin. To setup environments the popular Docker project is used. Docker allows you to create containers from any application. Only some knowledge is required for the setup of the containers. The rest of the configuration is done through commands most people are quite familiar with.

This was a talk I did in Dublin at an event called Redefining the Enterprise OS Breakfast Briefing - How to meet next-generation IT demands for Linux Containers, Docker, Performance & Systems Management http://techxperts.eu/events/redefining-the-enterprise-os-breakfast-briefing/

Gerrit is a code review system that tightly integrates with Git. It provides a web-based user interface and API for reviewing changes, managing access control, and integrating with other tools like Jenkins. Key features include fast and easy code reviews, flexible integration options, and tools for managing projects, users, and access control. Gerrit supports code review workflows and allows configuring commit policies and change submission actions.

Mayank Patel from Oildex gave a presentation on Jenkins 2 Pipelines. He discussed how pipelines allow continuous delivery through features like resilience, pausability, and efficiency. Pipelines can be configured as code in source control and provide security and reusability. The presentation covered the Jenkins environment, ideal pipeline flows, important plugins, and included a demo of a sample pipeline configured with Docker.

This document provides links to blogs and presentations about DevOps and Continuous Delivery practices using Docker from various sources. It includes over 25 references to external resources on topics like Docker Universal Control Plane, Continuous Delivery, clustering Jenkins, Docker introductions, monitoring deployments, Docker in build pipelines, and deploying containers to IBM Bluemix. The document promotes a one-day DevOps conference and offers a free private Docker registry and to share additional Docker reference architectures.

n this presentation you will learn why enterprises are so excited about OpenShift, the Container Platform by Red Hat. This platform leverages open source technologies like Docker and Kubernetes, to deliver a platform ready for agile application development, while providing ops the stability they need for production deployments. In this presentation we will cover how OpenShift meets these challenges, and give you some insight in how OpenShift is working.

Presented by: Igor Seletskiy Presented at the All Things Open 2021 Raleigh, NC, USA Raleigh Convention Center Abstract: IT Teams know the drill. New security bulletins, new issues, new patches to deploy. Schedule another maintenance operation and prepare for system downtime. There is a better way to do things. Live patching has been around in the Linux Kernel for some time now, but adoption has not been ideal so far - either because of a lack of trust in the technology or just lack of awareness - or sysadmins just enjoy interrupting their workloads or users. Live patching consists of two aspects. First, there has to be a mechanism for function redirection in the kernel. As in many things, the kernel actually provides three different subset of tools that provide this functionality - kprobes, fprobes and Livepatching. Secondly, Live Patching relies on a set of tools to generate the actual patches to deploy, replacing the old code with new one. This is arguably the most involved part: you need to fit your new code in the proper space, you can’t overwrite other unrelated code and you need to maintain compatibility with other functions. If you change your parameter list, for example, its game over - something will break in the worst possible way. In this talk we’ll go over issues like Consistency model, patch generation, deployment mechanisms and identify situations that are ideal candidates for live patching instead of traditional patching operations.

Snap CI enables software teams to do Continuous Delivery (CD). When practicing CD, the goal is to automate the deployment process and build software in such a way that it can be deployed to production any time. As a deployment tool, Snap CI cannot have downtime. If it did, our users would not be able to deploy their own software. We had to change Snap CI’s architecture to ensure zero-downtime and we chose to do blue-green deployments to achieve it. In this approach, we had to maintain two instances of our system: one active instance, and one inactive instance. Based on our experiences, we will share some tricks of the trade from the numerous challenges we faced such as: making the application aware of whether it was active or inactive, handling data migrations, and babysitting long-running jobs. These are the slides from Akshay Karle and Fernando Junior's presentation on Agile Brazil 2015.

Some tools such as Chef and Jenkins are used by engineers in ops to great effect. Rarely though, a technology brings a paradigm to the masses. Docker, like cloud virtualization is of this more rare breed.

At Containers & Cloud Native Roadhow in Milan and Rome, Italy, we discussed and demonstrated CI/CD Pipelines with OpenShift Container Platform. - OpenShift 3.9 - Jenkins - Jenkins Pipeline - Maven Pipeline (Groovy) - Blue-Green, Canary Deployments

OpenShift is a DevOps platform that provides a container application platform for deploying and managing containerized applications and microservices. It uses Kubernetes for orchestration and Docker containers. OpenShift provides features for the complete application lifecycle including continuous integration/delivery (CI/CD), automated image builds, deployments, networking, authentication, and integration with external services and registries. Developers can create and deploy applications from source code, templates, or Docker images to OpenShift without needing deep knowledge of Docker or Kubernetes.

Programming is a journey. To achieve effective, clean, easy-to-read, and beautiful Java code, you have to practice programming every day. This session shares some lessons collected along 15 years of Java programming. It includes live code examples of how to write truly object-oriented code; when to make a type (and how to use it on JPA providers); how to properly use encapsulation and polymorphism in "ifless" programming; how to properly take advantage of the enum power; and how to use some very useful open source libraries such as Google Guava and Joda-Time to achieve clean Java code. Session presented at JavaOne Latin America 2012.

This document provides an agenda and summaries of key points from a presentation on integrating systems using Apache Camel. The presentation discusses how Apache Camel is an open-source integration library that uses enterprise integration patterns to connect disparate systems. It highlights features of Camel including components, data formats, and testing frameworks. Customer examples are presented that demonstrate large returns on investment and cost savings from using Camel for integration projects. The presenters argue that Camel provides flexibility, reusability and rapid development of integrations.

Using apache camel for microservices and integration then deploying and managing on Docker and Kubernetes. When we need to make changes to our app, we can use Fabric8 continuous delivery built on top of Kubernetes and OpenShift.

What are and aren't microservices? Microservices is a validation of the open-source approach to integration and service implementation and a rebuff of the committee-driven SOA approach. In this

By Clement Escoffier Sorry, there is no free lunch—distributed applications are complex. You can embrace any trends such as microservices, but developing a distributed application is a challenge. Why? Distributed systems have many reasons to fail: technically they’re complicated, and the theory behind distributed systems is also complicated. Vert.x is a toolkit for building reactive distributed applications on top of the Java Virtual Machine in Java, JavaScript, Groovy, Ruby, or Ceylon. Vert.x does not hide the complexity of distributed applications; it lets you manage it. Vert.x applications are able to manage failures, can use several protocols and interaction styles, can handle heavy loads, and can cope with most of the requirements of modern applications.
