This document provides an introduction to DevOps and Docker. It discusses that DevOps aims to increase collaboration between development and operations teams to enable faster and more frequent software deployments. DevOps uses automation techniques and requires organizational buy-in. Docker is often used to configure development and test environments, with Docker for Windows and Mac now available. Swarm mode allows combining Docker engines across multiple servers for self-organization and high availability without a single point of failure.
Introduction Docker 1.12
- 1. Introduction to DevOps DevOps practices are most powerful when applied in contexts with software delivery and IT change management. DevOps, by definition, is never a “one size fits all” remedy. DevOps uses automation techniques to increase collaboration across development and operations, enabling faster, more predictable and more frequent deployments to market. DevOps is about drilling down your organisation's specific problem and challenges and resolve them. DevOps isn’t just a set of tools, but a philosophical shift that requires a buy-in from all folks involved for it to truly succeed. DevOps teams are finding it efficient to configure dev/test environments based on Docker.
- 2. Docker for Windows and Mac Public Beta Docker for Mac does not use VirtualBox, but rather HyperKit, a lightweight OS X virtualization solution built on top of Hypervisor.framework in OS X 10.10 Yosemite and higher. Installing Docker for Mac does not affect machines you created with Docker Machine.The install offers to copy containers and images from your local default machine (if one exists) to the new Docker for Mac HyperKit VM. If chosen, content from default is copied to the new Docker for Mac HyperKit VM, and your original default machine is kept as is. The Docker for Mac application does not use docker-machine to provision that VM but rather creates and manages it directly. At installation time, Docker for Mac provisions a HyperKit VM based on Alpine Linux, running Docker Engine. It exposes docker API on a socket in /var/tmp/docker.sock. Since this is the default location where docker will look if no environment variables are set, you can start using docker and docker-compose without setting any environment variables
- 3. Install Docker for windows and docker for Mac Download docker for windows and docker for mac from below URL http://www.docker.com/products/overview After the installation you will see docker running in status bar or process status
- 5. Swarm Mode Combine your engines in swarms of any scale Self organizing Self healing No external data store required No single point of failure Infrastructure-agnostic topology
- 6. Built-in Routing Mesh Swarm-wide overlay networking Container-native load balancing DNS based service discovery No separate cluster to setup Works with your existing load balancers Rock Solid kernel-only data path with IPVS
- 7. Docker Service API Desired State reconciliation Scaling Rolling updates Advanced Scheduling Application-specified health checks Rescheduling on node failure
- 8. Whats Next Docker for AWS and Docker for Azure
