Docker Compose by Aanand Prasad Docker, Inc.

Docker Compose allows users to define and run multi-container Docker applications with a single command (docker up). It uses a YAML file to configure the application's services and Docker to automatically build images and link containers. With Compose, complex applications can be started and stopped with a single command, rather than multiple docker run commands. It also integrates with the Docker API, allowing it to work with tools like Docker Swarm for multi-host clusters.

Docker orchestration using core os and ansible - Ansible IL 2015Leonid Mirsky

The last couple of years have seen an increasing interest in Docker and related technologies. One of these technologies is CoreOS, a new operating system built from the ground up for running Docker containers at scale. In this talk we will learn about CoreOS main concepts and tools. We will get our hands dirty as we work together toward a goal of running a CoreOS cluster on AWS (using Ansible) and running docker containers on it. The talk will conclude with a discussion on the place of Ansible (and configuration management tools in general) in the "next-generation" stack.

Docker composeFelipe Ruhland

Docker Compose allows developers to define and run multi-container Docker applications. It allows users to define services in a docker-compose.yml file that specifies images, networking, volumes, environment variables, and depends_on relationships between containers. Docker Compose then automates the creation and management of the containers by using a single command like docker-compose up. This makes it easier to develop, ship and run multi-container applications.

Docker: A New Way to Turbocharging Your Apps Developmentmsyukor

The Dockerfile Explosion and the Need for Higher Level Tools by Gareth RushgroveDocker, Inc.

Dockerfiles are great. They provide a zero-barrier-to-entry format for describing a single Docker image which is immediately clear to anyone reading them. But with that simplicity comes problems that become apparent as your adoption of Docker gathers pace. * Dockerfiles can inherit from other docker images, but images are not Dockerfiles * Dockerfile provides no built-in mechanism for creating abstractions, so as usage grows identical or similar instructions can be duplicated across many files * The Docker APi exposes a build endpoint, but the API is very course, taking Dockerfile as the transport rather than exposing the individual instructions * Dockerfiles are just that, files. So they can come from anywhere The one layer per line in a Dockerfile limitation can lead to an explosion of layers, which fail to take advantage of the promised space and performance benefits.

How analogue intelligence complements AIPaul Rowe

Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results. News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?

AI Changes Everything – Talk at Cardiff Metropolitan University, 29th April 2...Alan Dix

Talk at the final event of Data Fusion Dynamics: A Collaborative UK-Saudi Initiative in Cybersecurity and Artificial Intelligence funded by the British Council UK-Saudi Challenge Fund 2024, Cardiff Metropolitan University, 29th April 2025 https://alandix.com/academic/talks/CMet2025-AI-Changes-Everything/ Is AI just another technology, or does it fundamentally change the way we live and think? Every technology has a direct impact with micro-ethical consequences, some good, some bad. However more profound are the ways in which some technologies reshape the very fabric of society with macro-ethical impacts. The invention of the stirrup revolutionised mounted combat, but as a side effect gave rise to the feudal system, which still shapes politics today. The internal combustion engine offers personal freedom and creates pollution, but has also transformed the nature of urban planning and international trade. When we look at AI the micro-ethical issues, such as bias, are most obvious, but the macro-ethical challenges may be greater. At a micro-ethical level AI has the potential to deepen social, ethnic and gender bias, issues I have warned about since the early 1990s! It is also being used increasingly on the battlefield. However, it also offers amazing opportunities in health and educations, as the recent Nobel prizes for the developers of AlphaFold illustrate. More radically, the need to encode ethics acts as a mirror to surface essential ethical problems and conflicts. At the macro-ethical level, by the early 2000s digital technology had already begun to undermine sovereignty (e.g. gambling), market economics (through network effects and emergent monopolies), and the very meaning of money. Modern AI is the child of big data, big computation and ultimately big business, intensifying the inherent tendency of digital technology to concentrate power. AI is already unravelling the fundamentals of the social, political and economic world around us, but this is a world that needs radical reimagining to overcome the global environmental and human challenges that confront us. Our challenge is whether to let the threads fall as they may, or to use them to weave a better future.
