Docker Introduction at GDG DevFest 2015 Lagos
Docker is an open platform for building and running distributed applications across various environments. It allows applications to run in lightweight virtual containers that boot faster than traditional virtual machines and allow multiple containers to run on a single host. Docker provides benefits like easy distribution of applications, portability between development and production environments, and isolation that prevents applications from interfering with one another. The document then provides hands-on examples of using Docker to pull images, run containers, mount volumes, expose ports, build images, and set up automated builds.
Microservices: How loose is loosely coupled?
Microservice architecture is a popular design pattern for DevOps deployments of cloud native applications. It's single purpose, loosely coupled, bounded context design lends itself to the independent life cycle required to quickly deploy and scale in the cloud. Docker containerization of these services further aids in the zero down-time deployments of these horizontally scalable services. But how do you keep them loosely coupled? How do they communicate without knowing about each other? and how do you keep all of those containers patched from new vulnerabilities that are being discovered every day?
This talk discusses the implementation of a Container Vulnerability Remediation Services that itself is designed as a collection of loosely coupled microservices that communicate via publish/subscribe messaging model using Kafka, Cloud Functions (OpenWhisk), and REST APIs implemented in Python Flask. This design keeps each microservice independent and replaceable, while enabling expandability for new services to participate in business functions without any pre-determined knowledge of the business workflow.

Docker - Portable Deployment
Docker is a system for running applications in lightweight containers that can be deployed across machines. It allows developers to package applications with all dependencies into standardized units for software development. Docker eliminates inconsistencies in environments and allows applications to be easily deployed on virtual machines, physical servers, public clouds, private clouds, and developer laptops through the use of containers.
Introduction to Docker
This document provides an introduction to Docker, including:
- Docker allows developers to package applications with all dependencies into standardized units called containers that can run on any infrastructure.
- Docker uses namespaces and control groups to provide isolation and security between containers while allowing for more efficient use of resources than virtual machines.
- The Docker architecture includes images which are templates for creating containers, a Dockerfile to automate image builds, and Docker Hub for sharing images.
- Kubernetes is an open-source platform for automating deployment and management of containerized applications across clusters of hosts.
2 Linux Container and Docker
The Information Technology have led us into an era where the production, sharing and use of information are now part of everyday life and of which we are often unaware actors almost: it is now almost inevitable not leave a digital trail of many of the actions we do every day; for example, by digital content such as photos, videos, blog posts and everything that revolves around the social networks (Facebook and Twitter in particular). Added to this is that with the "internet of things", we see an increase in devices such as watches, bracelets, thermostats and many other items that are able to connect to the network and therefore generate large data streams. This explosion of data justifies the birth, in the world of the term Big Data: it indicates the data produced in large quantities, with remarkable speed and in different formats, which requires processing technologies and resources that go far beyond the conventional systems management and storage of data. It is immediately clear that, 1) models of data storage based on the relational model, and 2) processing systems based on stored procedures and computations on grids are not applicable in these contexts. As regards the point 1, the RDBMS, widely used for a great variety of applications, have some problems when the amount of data grows beyond certain limits. The scalability and cost of implementation are only a part of the disadvantages: very often, in fact, when there is opposite to the management of big data, also the variability, or the lack of a fixed structure, represents a significant problem. This has given a boost to the development of the NoSQL database. The website NoSQL Databases defines NoSQL databases such as "Next Generation Databases mostly addressing some of the points: being non-relational, distributed, open source and horizontally scalable." These databases are: distributed, open source, scalable horizontally, without a predetermined pattern (key-value, column-oriented, document-based and graph-based), easily replicable, devoid of the ACID and can handle large amounts of data. These databases are integrated or integrated with processing tools based on the MapReduce paradigm proposed by Google in 2009. MapReduce with the open source Hadoop framework represent the new model for distributed processing of large amounts of data that goes to supplant techniques based on stored procedures and computational grids (step 2). The relational model taught courses in basic database design, has many limitations compared to the demands posed by new applications based on Big Data and NoSQL databases that use to store data and MapReduce to process large amounts of data.

Containers and the Evolution of Computing
In recent years, Docker containers have become a key component of modern application design. Increasingly, developers are breaking their applications apart into smaller components and distributing them across a pool of compute resources. Using Docker on your local development machine is simple, but running Docker applications at scale in production can be difficult. In this session, we will discuss the difficulties of running Docker in production and how Amazon EC2 Container Service (ECS) can be used to reduce the operational burdens. We will give an overview of the core architectural principles underlying Amazon ECS., and we will walk through a number of patterns used by our customers to run their microservices platforms, to run batch jobs, and for deployments and continuous integration. We will also demonstrate how to define multi-container applications, deploy and scale them seamlessly on a cluster with Amazon ECS.

John Willis is Director of Ecosystem Development for Docker, which he joined after the company he co-founded, SocketPlane, was acquired by Docker. Previous to founding SocketPlane, he was the Chief DevOps Evangelist at Dell. He has also held past executive roles at Opscode/Chef and Canonical/Ubuntu. He is the author of 7 IBM Redbooks and is co-author of the “Devops Handbook”.
Are VMs Passé?
Ben Golub argues that while virtual machines (VMs) solved earlier problems of server consolidation, containers provide a better solution for modern application development and deployment needs. Containers offer several advantages over VMs, including faster provisioning, greater density, near bare-metal performance, and more flexibility. Golub outlines how Docker addresses earlier issues with containers by making them lightweight, standardized, interoperable and easy to automate across environments. This allows applications to be packaged and run consistently regardless of infrastructure. Golub believes containers allow for a better separation of application management from infrastructure management compared to VMs.

Microservices, Containers and Docker
This document provides an overview of microservices, containers, and Docker. It begins by defining microservices as an architectural style where applications are composed of independent, interchangeable components. It discusses benefits of the microservices style such as independent deployability, efficient scaling, and design autonomy. The document then introduces containers as a way to package applications and their dependencies to run uniformly across various environments. It compares containers to virtual machines. Finally, it describes Docker as an open source tool that automates deployment of applications into containers, providing portability and management of containers. The document concludes by discussing the need for container orchestration at scale.
Docker intro
Docker is an open-source project that allows developers to package applications into lightweight, portable containers that can run on any Linux server. Containers isolate applications from one another and the underlying infrastructure, while still sharing operating system resources to improve efficiency. Docker eliminates inconsistencies between development and production environments by allowing applications to run identically in any computing environment, from a developer's laptop to the cloud. This portability and consistency accelerates the development lifecycle and improves deployment workflows for both developers and operations teams.
