You are done coding and have got a runnable Jar file, but then what? How does it go into the cloud?
In this talk we will explore how Java can be packaged inside a Docker image and discuss tips and common pitfalls.
We will continue with a brief introduction to Kubernetes and how it can help deploying our Docker containers.
Finally will look at a development workflow which allows local development of large micro-services apps leveraging Telepresence.
Dockerize your Symfony application - Symfony Live NYC 2014André Rømcke
With the advent of docker it is now easier then ever to make sure you develop, test and deploy using the same environment, resulting in no more issues caused by differences or missing libraries. Talk will go into the basics of containers, docker, and showcase how you might setup a basic php + mysql environment for your symfony app.

Presentation I presented at Codemotion 2015 in Rome.
It's about how to build and share reproducible, portable development environments with Vagrant and Docker
Dockerizing Symfony2 application. Why Docker is so cool And what is Docker? And what are Containers? How they works? What are the ecosystem of Docker? And how to dockerize your web application (can be based on Symfony2 framework)?
Getting instantly up and running with Docker and SymfonyAndré Rømcke
A look into how you can start to use Docker today with ready made setup with php7, nginx, redis, blackfire and so on. How you may extend it, and integrating it into your continuous integration workflow, and how you can setup a continuous deployment workflow using for instance Travis-CI.

Docker All The Things - ASP.NET 4.x and Windows Server ContainersAnthony Chu
Docker is awesome and there's been a lot of excitement over .NET Core running in Linux containers. But why do older apps have to miss out on the fun? With Windows Server 2016 and Windows Server containers, there's finally a way to dockerize .NET 4.6 apps using the same Docker tools and commands as we're used to on Linux. In this intermediate level talk, I'll give an overview of Docker and Windows Server containers. Then I'll demonstrate different ways to run existing ASP.NET Web API, MVC, and even WebForms applications inside Docker containers.

In this Cloud-Native era, it is difficult not to have heard about Kubernetes (k8s). Social media are flooded with technical articles on Kubernes and it is a popular topic at many cloud-related conferences. Major internet companies, such as Reddit or AirBnQ, have been switching their production environment to k8s. But why the fuss? What exactly is Kubernetes? What problem does it solve? Should you learn more about it? If you have asked yourself one of these questions this talk is for you.
During this talk you will:
* Understand the context and problem k8s is trying to solve
* Learn the basic building blocks and features of k8s
* Receive a list of resources to start your own journey with k8s

From Monolith to Docker Distributed ApplicationsCarlos Sanchez
Docker is revolutionizing the way people think about applications and deployments. It provides a simple way to run and distribute Linux containers for a variety of use cases, from lightweight virtual machines to complex distributed microservice architectures. But migrating an existing Java application to a distributed microservice architecture is no easy task, requiring a shift in the software development, networking, and storage to accommodate the new architecture. This presentation provides insights into the experience of the speaker and his colleagues in creating a Jenkins platform based on distributed Docker containers running on Apache Mesos and Marathon and applicable to all types of applications, especially Java- and JVM-based ones.
Why everyone is excited about Docker (and you should too...) - Carlo Bonamic...Codemotion
In less than two years Docker went from first line of code to major Open Source project with contributions from all the big names in IT. Everyone is excited, but what's in for me - as a Dev or Ops? In short, Docker makes creating Development, Test and even Production environments an order of magnitude simpler, faster and completely portable across both local and cloud infrastructure. We will start from Docker main concepts: how to create a Linux Container from base images, run your application in it, and version your runtimes as you would with source code, and finish with a concrete example.
Docker Container As A Service
X11 Linux apps on mac in a container.
In container Java development with STS or Eclipse in a container.
Docker UCP and swarm load balancing with Interlock.
The Nova driver for Docker has been maturing rapidly since its mainline removal in Icehouse. During the Juno cycle, substantial improvements have been made to the driver, and greater parity has been reached with other virtualization drivers. We will explore these improvements and what they mean to deployers. Eric will additionally showcase deployment scenarios for the deployment of OpenStack itself inside and underneath of Docker for powering traditional VM-based computing, storage, and other cloud services. Finally, users should expect a preview of the planned integration with the new OpenStack Containers Service effort to provide automation of advanced containers functionality and Docker-API semantics inside of an OpenStack cloud.
Note that the included Heat templates are NOT usable. See the linked Heat resources for viable templates and examples.
Getting started with Docker sandboxes for MariaDBMariaDB plc
MariaDB recently introduced a pair of Docker sandboxes for running MariaDB clusters. The sandboxes, using Docker Compose, make it easy to run a local MariaDB cluster for transactional and/or analytical processing. The transactional sandbox starts up a MariaDB cluster with replication and automatic failover while the analytical sandbox starts up a MariaDB AX cluster with sample data and an Apache Zeppelin notebook.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
