Habitat talk at CodeMonsters Sofia, Bulgaria Nov 27 2018

Docker Swarm is an orchestration tool that manages Docker applications running across a cluster of Docker nodes. It allows deploying containers to nodes within the cluster. There are two types of nodes: manager nodes that maintain the cluster and worker nodes that receive and run tasks from the manager. The manager knows the state of workers and workers accept tasks from the manager, reporting their status back. Services deploy containers to nodes using a description file.

Deploy, manage and scale Kubernetes with Rancher - a session given in ContainerConf 2017 (7th April) in Bangalore

Elton Stoneman - Developer Advocate, Docker Legacy applications weren't designed to run in a modern distributed platform like Docker. They have their own ideas about logging, configuration and health which don't translate to the world of containers and make transformation projects hard. This session shows you how to bring your old applications into the modern world, and integrate them with Docker - without changing code. We'll cover patterns for all the core application concerns: * logging * configuration * monitoring * health * dependency management The sample applications will be in .NET and Java, and will show you how to turn your existing applications into good Docker citizens.

Jules Testard - Software Engineer, Docker Inc Since the advent of AWS Lambda in 2014, the Function as a Service (FaaS) programming paradigm has gained a lot of traction in the cloud community. Since then, interest has increased for developers and entreprises to build their own open source solutions on top of Kubernetes. A number of competing frameworks in this space have been developed. In this talk, we will look at three specific frameworks (OpenFaas, Nuclio and FN) and for each framework we will: Show how to create, deploy, and invoke a function using that framework Show how Docker images and containers are used by each framework under the hood Investigate how the frameworks leverage KNative to build, ship and run applications on Kubernetes

Slides from the presentation "CI/CD Patterns for Kubernetes with Spinnaker" at Spinnaker Summit 2018, by Andrew Phillips and Lars Wander

This document discusses monitoring Docker containers and applications. It outlines the challenges of monitoring at the container, application, and infrastructure levels. An approach is proposed that uses agents running on each host to collect data from drivers for the host, containers, and applications. The data is sent asynchronously to a central monitoring controller which aggregates, stores, analyzes and derives insights from the data. Predictions, usage patterns, and capacity planning information can be determined to help optimize container resources and performance.

This document discusses the "mushroom cloud effect" that can occur when containers fail in highly dynamic container environments. It describes how a failure in one container due to a lack of disk space on the host led to cascading failures that affected many dependent services. The failure spread as container health checks failed and orchestration rescheduled containers, eventually exhausting disk space and preventing any new containers from running. Automated monitoring is needed to pinpoint the root cause of such cascading failures in complex systems with many interdependent containers and services.

This is slides from my talk on Kharkiv IT Weekend on May 27, 2017. Here is link to my blog where you can find more information about the approaches: https://devraccoon.com/2017/05/30/hashicorp-tools-on-it-weekend-kharkiv/

Elara is a Docker volume plugin that provides a distributed volume management tool and connection between containers and shared storage providers. It supports advanced volume operations like snapshots, backups, migration, IOPS, disk quotas and extending volumes. Elara uses a key-value storage as a database to store node status remotely. It focuses on shared storage and supports multiple backend drivers like NFS, Cinder and filesystem/block devices.

Presented by: Brent Laster Presented at the All Things Open 2021 Raleigh, NC, USA Raleigh Convention Center Abstract: Containers are all the rage these days – from Docker to Kubernetes and everywhere in-between. But to get the most out of them it can be helpful to understand how containers are constructed, how they depend and interact with the operating system, and what the differences and interactions are between layers, images, and containers. Join R&D Director, Brent Laster as he does a quick, visual overview of how containers work and how applications such as Docker work with them. Topics to be discussed include: • What containers are and the benefits they provide • How containers are constructed • The differences between layers, images, and containers • What does immutability really mean • The core Linux functionalities that containers are based on • How containers reuse code • The differences between containers and VMs • What Docker really does • The Open Container Initiative • A good analogy for understanding all of this

Join engineers from ClusterHQ and Dell Storage to learn about persistent storage integration with Docker. See how Flocker enables native support for enterprise storage infrastructure use in containers, enabling you to leverage Dell storage for new workloads.

This document discusses best practices for setting up a Docker and Kubernetes environment. It covers topics like Docker storage drivers, Docker networking, Kubernetes authentication and authorization, exposing services, integrating logging and monitoring. The key recommendations are to use OverlayFS or Devicemapper storage, Calico networking, Kubernetes security policies, namespaces and RBAC, and Ingress for exposing services. ETCD backup and fault tolerance is also important.

This document discusses how Docker can transform development and deployment processes for modern applications. It outlines some of the challenges of developing and deploying applications across different environments, and how Docker addresses these challenges through containerization. The document then provides examples of how to dockerize a Rails and Python application, set up an Nginx reverse proxy with Let's Encrypt, and configure a Docker cluster for continuous integration testing.

Infrastructure as Code, tools, benefits, paradigms and more. Presentation from DigitalOnUs DevOps: Infrastructure as Code Meetup (September 20, 2018 - Monterrey Nuevo Leon MX)

This document discusses software-defined networking (SDN) and network automation using DevOps tools. It defines SDN as a programmatic framework to optimize network services delivery and management. It explains that SDN solutions can be either vendor-developed or custom-built. The document then discusses DevOps and how network engineers can integrate networks into DevOps workflows through practices like NetDevOps. It provides examples of controller-based and tool-based network abstraction using technologies like Ansible, Cisco ACI, and OpenDaylight. The rest of the document demonstrates network automation concepts and compares orchestration tools from vendors like Cisco, Ansible, Chef, and SaltStack.

Docker is not just about deploying containers to hundreds of servers. Developers need tools that help with day-to-day tasks and to do their job more effectively. Docker is a great addition to most workflows, from starting projects to writing utilities to make development less repetitive. Docker can help take care of many problems developers face during development such as “it works on my machine” as well as keeping tooling consistent between all of the people working on a project. See how easy it is to take an existing development setup and application and move it over to Docker, no matter your operating system.

The document outlines the agenda for the OpenStack Summit in November 2013. The agenda includes sessions on Docker and its ecosystem, using Docker with OpenStack and Rackspace, and a cross-cloud deployment demo. Docker is presented as a solution for developing and deploying applications across multiple environments by encapsulating code and dependencies in portable containers. It can help eliminate inconsistencies between development, testing, and production environments.

The document outlines the agenda for the OpenStack Summit in November 2013, including presentations on Docker and its ecosystem, how Docker can be used with OpenStack and Rackspace, and a demonstration of cross-cloud application deployment using Docker. Docker is presented as a solution to the "matrix from hell" of running applications across different environments by providing lightweight, portable containers that can run anywhere regardless of the operating system. The summit aims to educate attendees on Docker and showcase its integration with OpenStack for simplified and efficient application deployment and management across multiple clouds.

Mandi Walls is the Technical Community Manager for EMEA at Chef and the Habitat Community lead is Ian Henry. The document discusses how modern applications are trending toward immutability, platform agnosticism, complexity reduction, and scalability. It provides an overview of ways to work with Habitat, including using artifacts that run themselves via the supervisor, exporting to Docker, and building plans from scratch or using scaffolding.
