Real World Experience of Running Docker in Development and Production

Running Docker in Development & Production (DevSum 2015)

These days applications are getting more and more complex. It's becoming quite difficult to keep track of all the different components an application needs in order to function (a database, a message queueing system, a web server, a document store, a search engine, you name it.). How many times we heard 'it worked on my machine'?. In this talk we are going to explore Docker, what it is, how it works and how much it can benefit in keeping the development environment consistent. We are going to talk about Dockerfiles, best practices, tools like fig and vagrant, and finally show an example of how it applies to a ruby on rails application.

Streamline your development environment with docker

Giacomo Bagnoli

Docker is a groundbreaking technology that will heavily influence how we will write software in the years to come: let's then have a look at: * where it comes from (Linux Containers) * how it works * how to dockerize simple apps to easily deploy them on production * how you can use Docker in local environments to simplify your development workflow Do you like Vagrant, auto-scaling or 12-factor apps? Then get ready to be mindblown.

DockerCon Open Source Summit: BuildKit Akihiro Suda, NTT Corporation Building images on Kubernetes is attractive for distributing workload across multiple nodes, typically in CI/CD pipeline. However, it had been considered dangerous due to the dependency on `securityContext.privileged`. In this talk, Akihiro will show how to use Rootless BuildKit in Kubernetes, which can be executed as a non-root user without extra `securityContext` configuration.

The perl on most linux distros is a mess. Docker makes it easier to build and packge a local perl and applications. Problem is that Docker's manuals produce a mess of their own. Distributing perl on top of Gentoo's stage3 distro, busybox, or nothing at all made good alternatives. This talk includes basics of setting up docker, building a local perl for it, and packaging perl or applications into images for use in containers.

In this tutorial we will go over setting up a standard LEMP stack for development use and learn how to modify it to mimic your production/pre-production environments as closely as possible. We will go over how to switch from Nginx to Apache, upgrade PHP versions and introduce additional storage engines such as Redis to the equation. We'll also step through how to run both unit and acceptance suites using headless Selenium images in the stack. Leave here fully confident in knowing that whatever environment you get thrown into, you can replicate it and work in it comfortably.

OpenStack ran into a challenge: how do you balance the ability to evolve a REST API, with backwards compatibility guarantees, and have it work the same across different deployments, when you have no control over when they are going to upgrade. The answer we came up with was labeled "Microversions", inspired by HTTP content negotiation. This talk will dig into the challenges of versioning REST APIs, as well as the unique challenges of versioning ones that expect to exist in interoperable public clouds. It will dive through ideas that were tried and retired in OpenStack, and describe in depth the microversion system that many OpenStack services now use. We'll look at what's been learned in 2 years of this in the field, and suggest how related approaches might be applied to other open source projects.

DevOps is gericht op het tot stand brengen van een cultuur binnen organisaties waardoor het ontwikkelen, valideren en releasen van software sneller, meer betrouwbaar en frequenter kan verlopen. Om dit te realiseren staan het automatiseren van het 'software delivery process' en de bijhorende infrastructurele veranderingen centraal. Door de opkomst van 'Microservice Architecture' neemt het belang hiervan nog verder toe.

Stijn Wijndaele

Sprekers: Stijn Van den Enden & Stijn Wijndaele (ACA IT-Solutions) DevOps is gericht op het tot stand brengen van een cultuur binnen organisaties waardoor het ontwikkelen, valideren en releasen van software sneller, meer betrouwbaar en frequenter kan verlopen. Om dit te realiseren staan het automatiseren van het 'software delivery process' en de bijhorende infrastructurele veranderingen centraal. Door de opkomst van 'Microservice Architecture' neemt het belang hiervan nog verder toe. In deze avondconferentie werd, na een korte toelichting over DevOps, nagegaan wat Docker en de Cloud kunnen betekenen voor uw business, en hoe zij als enablers kunnen dienen voor het tot stand brengen van een DevOps-cultuur. Het container-landschap waarvan tools zoals Kubernetes, Docker Swarm, ...een belangrijk onderdeel vormen, wordt toegelicht en er wordt ingegaan op de wijze waarop deze tools aangewend kunnen worden om 'development' en 'operations' efficiënt te laten samenwerken.

Why write two add-ons when you can write one and deploy it to both Server and Cloud? Charles Gutjahr from ThinkTilt shares how they brought their Connect add-on to different clouds. Learn how he packaged the add-on in a Docker container to offer it behind the firewall. Hear about the implications for installation, data storage, security, and functionality. By the end of the talk, you'll be able to decide whether Dockerization is the right choice for your add-on. Charles Gutjahr, Co-Founder and Technology Architect, ThinkTilt

microXchg 2019, Berlin: Talk by Mario-Leander Reimer (@LeanderReimer, Principal Software Architect at QAware) === Please download slides if blurred! === Abstract: Only a few years ago the move towards microservice architecture was the first big disruption in software engineering: instead of running monoliths, systems were now build, composed and run as autonomous services. But this came at the price of added development and infrastructure complexity. Serverless and FaaS seem to be the next disruption, they are the logical evolution trying to address some of the inherent technology complexity we are currently faced when building cloud native apps. FaaS frameworks are currently popping up like mushrooms: Knative, Kubeless, OpenFn, Fission, OpenFaas or Open Whisk are just a few to name. But which one of these is safe to pick and use in your next project? Let's find out. This session will start off by briefly explaining the essence of Serverless application architecture. We will then define a criteria catalog for FaaS frameworks and continue by comparing and showcasing the most promising ones.

The Challenges of Becoming Cloud Native

Ben Hall

At Adobe APIs are powering the next generation of Creative applications. Mesos makes it very easy and fun to deploy and run Robust and Scalable Microservices in the Cloud. Today's technologies offer simple solutions to create RESTfull services while Mesos brings them to life faster. As the number of microservices increase and the inter communication between them becomes more complicated, we soon realize we have new questions awaiting our answers: how do microservices authenticate ? how do we monitor who's using the APIs they expose ? How do we protect them from attacks ? How do we set throttling and rate limiting rules across a cluster of microservices ? How do we control which service allows public access and which one we want to keep private ? How about Mesos APIs and its frameworks ? Can they benefit from these features as well ? Come and learn a scalable architecture to manage microservices in Mesos by integrating an API Management layer inside your Mesos clusters. This presentation will show you what an API Management layer is, what it's composed of and how it can help you expose microservices in a secure,managed and highly-available way, even in multi-Mesos cluster setups. During this session you will also have the opportunity to learn how Adobe's API Platform solved this problem, where it is today and what it envisions do to with Mesos further. If you're working with microservices already or you're creating new ones then this presentation is for you. Come and learn how Mesos together with an API management layer will make you a microservices hero in your organisation. At Adobe APIs are powering the next generation of Creative applications.

Slides of my February 2021 talk at FOSS Backstage, https://foss-backstage.de Moving house with the help of a group of friends is an interesting exercise in collective improvisation and coordination. Everybody can help with most of the jobs at hand, so the challenge is to keep people busy in a meaningful way, to make the best use of the physical and intellectual resources available, while keeping people happy and engaged. Sounds familiar? The Moving House model does apply to other types of group projects, including software development. Adhocracy, Asynchronous Collaboration and a can-do attitude, as practiced in Open Source communities, are key elements that enable groups that have no formal structure to collaborate efficiently and smoothly - like when helping friends moving house.

Ma présentation à https://www.blendwebmix.com/ 2019 Video: https://youtu.be/eE7YhQpPdcM?t=4560 Dans un monde qui se numérise toujours plus, les logiciels libres sont partout: dans votre téléphone, votre ascenseur, votre voiture, votre banque, etc… plus que jamais, l’Open Source est au coeur de notre monde numérique. Au-delà de ces contributions très concrètes au bien-être de nos sociétés, les communautés Open Source ont aussi inventé et mis en pratique des techniques de collaboration innovantes, distribuées, asynchrones. Souvent sans chef clairement identifié, ni planification précise, ces groupes de travail informels produisent des logiciels de grande qualité, qui pour certains ont créé des marchés ou révolutionnés les pratiques numériques. Le succès de ces groupes est étonnant quand on le compare aux nombreux projets informatiques ratés dans des groupes beaucoup plus structurés, entreprises ou organismes d’Etat par exemple. L’Open Source change le monde…vraiment? Tout en gardant les choses en perspective, nous présenterons plusieurs exemples concrets où cela se vérifie, par la création d’outils partagés, la découverte de talents, la diffusion des connaissances et la création de logiciels d’infrastructure qui sont devenus des standards de l’industrie.

Slides of my talk at ApacheCon EU 2019in Berlin, Germany: Shared Neurons - the Secret Sauce of Open Source communities? See also the video recording at https://www.youtube.com/watch?v=pWG-F3vW24w Open Source communities sometimes speak of Shared Neurons when great ideas come together as if sparked by a giant collective brain. Can we take inspiration from them and foster such neuron sharing in our teams? We will describe the tools and techniques used by successful Open Source projects to "put their brains together", by communicating openly and often, exposing concrete ideas early in prototype code, collaborating asynchronously and deliberately slowing things down to take advantage of unexpected Eureka moments. Based on years of experiences in multiple Open Source projects, this talk will help you better understand what makes our communities so powerful and how to transpose this in your own teams.

The presentation of the talk "Solid Pods Vs Personal Knowledge Graphs: Similarities and Differences" that was given by the PhD researcher Eleni Ilkou, in the 2nd Solid Symposium. Abstract: Solid Pods and Personal Knowledge Graphs are pioneering constructs within the Semantic Web community, each offering unique avenues for empowering individuals in the digital realm. Solid Pods stand as decentralized bastions of data control which grant users unprecedented authority over their digital presence, ensuring ownership, privacy and portability of personal data. Personal Knowledge Graphs infuse personal data and activity with contextual relevance, facilitating the synthesis and discovery of knowledge. This presentation aims to briefly reflect on the main similarities and differences among the Solid Pods and Personal Knowledge Graphs.
