Docker is an open platform for developing, shipping, and running applications. It allows packaging applications into standardized units for software called containers that can run on any infrastructure. The key components of Docker include images, containers, a client-server architecture using Docker Engine, and registries for storing images. Images act as templates for creating containers, which are run-time instances of images. Docker provides portability and isolation of applications using containers.

You will also see how to launch multiple docker containers using Docker Compose. Finally, it will also tell you the role Docker plays in the DevOps life-cycle. The Hands-On session is performed on an Ubuntu-64bit machine in which Docker is installed.

This document provides an overview of Docker Swarm and how to set up and use a Docker Swarm cluster. It discusses key Swarm concepts, initializing a cluster, adding nodes, deploying services, rolling updates, draining nodes, failure scenarios, and the Raft consensus algorithm used for leader election in Swarm mode. The document walks through examples of creating a Swarm, adding nodes, deploying a service, inspecting and scaling services, rolling updates, and draining nodes. It also covers failure scenarios for nodes and managers and how the Swarm handles them.

Docker is a platform that allows users to build, ship, and run applications by using containers. It solves issues like dependency conflicts, portability, and consistency across development and production. Docker uses containers- isolated environments that package code and dependencies together- to deliver software quickly and reliably. Key Docker concepts include images (read-only templates for creating containers), volumes (for persistent data), registries (for sharing images), and compose files (for defining multi-container apps). Docker also provides networking and clustering functionality to connect containers across multiple hosts.

Docker is a technology that uses lightweight containers to package applications and their dependencies in a standardized way. This allows applications to be easily deployed across different environments without changes to the installation procedure. Docker simplifies DevOps tasks by enabling a "build once, ship anywhere" model through standardized environments and images. Key benefits include faster deployments, increased utilization of resources, and easier integration with continuous delivery and cloud platforms.

Docker allows for easy deployment and management of applications by wrapping them in containers. It provides benefits like running multiple isolated environments on a single server, easily moving applications between environments, and ensuring consistency across environments. The document discusses using Docker for development, production, and monitoring containers, and outlines specific benefits like reducing deployment time from days to minutes, optimizing hardware usage, reducing transfer sizes, and enhancing productivity. Future plans mentioned include using Kubernetes for container orchestration.

This document provides an introduction to Docker. It begins by introducing the presenter and agenda. It then explains that containers are not virtual machines and discusses the differences in architecture and benefits. It covers the basic Docker workflow of building, shipping, and running containers. It discusses Docker concepts like images, containers, and registries. It demonstrates basic Docker commands. It shows how to define a Dockerfile and build an image. It discusses data persistence using volumes. It covers using Docker Compose to define and run multi-container applications and Docker Swarm for clustering. It provides recommendations for getting started with Docker at different levels.

- The document introduces Docker, explaining that it provides standardized packaging for software and dependencies to isolate applications and share the same operating system kernel. - Key aspects of Docker are discussed, including images which are layered and can be version controlled, containers which start much faster than virtual machines, and Dockerfiles which provide build instructions for images. - The document demonstrates Docker's build, ship, and run workflow through examples of building a simple image and running a container, as well as using Docker Compose to run multi-container applications like WordPress. It also introduces Docker Swarm for clustering multiple Docker hosts.

If you’re working with just a few containers, managing them isn't too complicated. But what if you have hundreds or thousands? Think about having to handle multiple upgrades for each container, keeping track of container and node state, available resources, and more. That’s where Kubernetes comes in. Kubernetes is an open source container management platform that helps you run containers at scale. This talk will cover Kubernetes components and show how to run applications on it.

Docker is a tool that allows applications to run in isolated containers to make them portable and consistent across environments. It provides benefits like easy developer onboarding, eliminating application conflicts, and consistent deployments. Docker tools include the Docker Engine, Docker Client, Docker Compose, and Docker Hub. Key concepts are images which are templates for containers, and containers which are where the code runs based on an image. The document outlines how to build custom images from Dockerfiles, communicate between containers using linking or networks, and deploy containers using Docker Compose or in the cloud.

Containers are not virtual machines - they have fundamentally different architectures and benefits. Docker allows users to build, ship, and run applications inside containers. It provides tools and a platform to manage the lifecycle of containerized applications, from development to production. Containers use layers and copy-on-write to provide efficient application isolation and delivery.

Société Générale knows that containers and the cloud are the future of the IT industry and have been using Docker EE for over a year and a half. In this talk, we will share how Docker EE fits into our global strategy and our architecture for integrating the platform to our existing IT systems. We will go over tradeoffs of how we operationalized the platform to provide a highly available CAAS to our global enterprise. Finally, we will share how we are onboarding development teams and deploying their applications to production.

Docker is a runtime for Linux Containers. It enables "separation of concern" between devs and ops, and solves the "matrix from hell" of software deployment. This presentation explains it all! It also explains the role of the storage backend and compares the various backends available. It gives multiple recipes to build Docker images, including integration with configuration management software like Chef, Puppet, Salt, Ansible. If you already watched other Docker presentations, this is an actualized version (as of mid-November 2013) of the thing!

This document discusses Gilt's strategy of using immutable infrastructure with Docker and EC2 to enable continuous delivery and minimize risk when deploying new software versions. Some key points made include: - Gilt builds Docker containers for each new application version, creates a new "stack" of infrastructure to run the container, and uses incremental rollout and automated rollback to reduce risk. - Immutable infrastructure emerges naturally with Docker since each version requires new containers and infrastructure rather than updating existing instances. - Automating deployment, rollback, and incremental rollout across new infrastructure stacks reduces probability, cost and occurrences of failures when deploying new versions. - Instant rollback is possible by moving traffic back to the previous version's infrastructure if
