Oliver Pomeroy, Docker & Laura Tacho, Cloudbees Enterprises often want to provide automation and standardisation on top of their container platform, using a pipeline to build and deploy their containerized applications. However this opens up new challenges; Do I have to build a new CI/CD Stack? Can I build my CI/CD pipeline with Kubernetes orchestration? What should my build agents look like? How do I integrate my pipeline into my enterprise container registry? In this session full of examples and how-to's, Olly and Laura will guide you through common situations and decisions related to your pipelines. We'll cover building minimal images, scanning and signing images, and give examples on how to enforce compliance standards and best practices across your teams.

Open-source machine learning can be transformative, but without the proper tools in place, enterprises struggle to balance the IT security and governance requirements with the need to deliver these powerpoint tools into the hands of their developers and modelers. How can organizations get the latest technology from the open-source brain trust, while ensuring enterprise-grade management and security? In this webinar, we will discuss how Anaconda Team Edition, available on RedHat Marketplace, enables IT departments to mirror a curated set of packages into their organization in a safe and governed way. Join Michael Grant, VP of services at Anaconda, to discuss: How IT organizations are using Anaconda Team Edition to curate, govern and secure Python and R packages Tips for how development and data science teams can get the most out of Team Edition, from uploading your own packages to building custom channels for groups or projects How to distribute conda environments to desktops, servers and clusters: GUI-based installers for desktop users “Conda packs” for automated delivery to remote servers and distributed computing clusters Conda-enabled Docker containers for application deployment

Kubernetes adoption is straight forward when starting from scratch or in public clouds, but what the journey looks like when your starting point is a legacy infrastructure with high-traffic? In this talk we present our experience that begun almost 1 year ago and challenged everything inside our organisation. Developer teams changed the way they work, product owners benefit from the new speed achieved and the need of new roles emerged in IT department. We will explain our lessons learnt and the way to get the best out of this solution.

Brian Christner, 56k + Docker Captain - In this session, we will unlock the full potential of using Microsoft Visual Studio Code (VS Code) and Docker Desktop to turn you into a Docker Power User. When we expand and utilize the VS Code Docker plugin, we can take our projects and Docker skills to the next level. In addition to using VS Code, we streamline our Docker Desktop development workflow with less context switching and built-in shortcuts. You will learn how to bootstrap new projects, quickly write Dockerfiles utilizing templates, build, run, and interact with containers all from VS Code.

Mohammed Aboullaite, xHub Nowadays, containers are more than a cool new tool to play with - they've revolutionized the way we develop, architect and ship software and have become part of our day-to-day operations. On the other hand, Java has been around for more than 2 decades, dominating the entreprise world. Both advocate the "RUN anywhere" principal, but, is it that easy? No! Your perfect working local container will most probably fail on production because of MEMORY &/or CPU issues, since jvm apps assume they OWN the server they are running on. This session will look at the gotchas of running JVM apps in containers & how to avoid costly pitfalls. We will cover: _ what updates Java 10 brought to the table to improve container awareness and the issues related to prior versions, including how to address each one of them to avoid the mess. - tips and tricks to obtain smaller images & best practices while writing your DockerFiles - some plugins to helps non-containers experts integrate docker in their development process; and - the concept of "Distroless" Docker Images and how to benefit from it.

Kubernetes is a powerful, operational platform for containerized applications. However, the developer workflow on Kubernetes – how you code, deploy, update, and monitor your services – is much less mature. How should you lay out your Git repo? How do you create loosely coupled services? How do you support deploying your service at any time? In this talk, we’ll talk about these questions and more. We’ll discuss the journey towards a rapid development workflow, discuss best practices, and, talk about the process we followed to get to a rapid development workflow. DevOps Days Boston 2017

>>> View this presentation online at http://github-service-universe.kimminich.de/ <<< PDF version of the slide deck for my JavaLand 2015 talk "All-round careful Software Development with GitHub Services" Tools for unit testing, building applications, analyzing software quality and planning release scopes are an essential aspect of modern software development. With GitHub and "pluggable" external services there are lots of options to move these aspects into "the Cloud". For open source projects this is a viable alternative to on-premise solutions. In this talk I will present and demonstrate the CI lifecycle of some of my recent projects hosted on GitHub where I tried to integrate modern tools (e.g. Gradle, npm, bower) and external services (e.g. Travis-CI, Code Climate, Coveralls, HuBoard, AmazonSNS, NMA). The benefits and limitations of those services will be honestly illuminated. I am not affiliated with any of the providers mentioned, so this talk will not end up as a marketing show! Instead, the audience is supposed go out of this talk with some new things to try out with their own GitHub projects while hopefully being able to avoid some of the ramp-up difficulties.

In a productive cloud-native development workflow, individual teams can build and ship software independently from each other. But with a rapidly evolving Cloud Native Landscape, creating an effective developer workflow on Kubernetes can be challenging. We are all creating software to support the delivery of value to our customers and to the business, and therefore, the developer experience from idea generation to running (and observing) in production must be fast, reliable, and provide good feedback. In this webinar, we’ll discuss: - Why an efficient development workflow is so important - The role of Kubernetes, Envoy, Prometheus, and other popular cloud-native tools in your workflow - Key considerations in implementing a cloud-native workflow

Feeling overwhelmed while getting started with containers? Have you been tasked to figure out how to train everyone back at your organization? There's just so much to learn and teach! In this talk, we'll start with a tiny bit of history to motivate the "why" and quickly move into the "what" by explaining what container and images actually are (they're not just magical black boxes!). We'll talk about how volumes help with data persistence and include an overview of Docker Compose and even orchestration. There will be plenty of live demos and fun!

Talk at Dev Days Riga 2018: Kubernetes has rapidly grown to support many container runtime formats. In this talk, I'm presenting all the alternatives you have to run your applications in kubernetes, and will present CRI-O which is steadily becoming a replacement to run your Docker containers on production. And since you will no longer have Docker, how will you build now your Docker containers? Buildah is a project that facilitates building Docker containers in a Dockerless world.

Modeling languages are generally applied for developing systems and software – both internally, with domain-specific languages, and with standardized languages targeting a general purpose and a wide audience. Way too often these languages are weakly created and defined leading to poor quality: Language definitions tend to contain errors and inconsistencies; notations do not recognize the communication and problem-solving needs of humans; standardization organizations push exchange formats that do not fully work and offer certificates that do not measure mastery of the language. We describe common problems in language development and point them out with examples from known cases. To overcome these problems, we suggest several solutions to improve language development, including using modeling languages specifically designed to define modeling languages, continuous testing and prototyping, and keeping language users in the loop.
