OpenShift runs on user's choice of infrastructure and allows developers to deploy and manage applications. It uses Kubernetes to orchestrate nodes and applications across a cluster. Developers can log in and create new projects to deploy containerized applications using services like Docker images. OpenShift provides replication, easy scaling, and automated recovery of applications. It also supports linking applications to shared storage and exposing routes for external access.
The document provides an overview and cheat sheet for using the OpenShift command line interface. It defines what OpenShift is, lists common commands for login/authentication, managing projects and resources, building and deploying applications, and provides an example of creating a new project, adding users, building an application from source code and image, and checking the status of deployed resources.
Mukta Aphale presented at ChefConf 2015. She discussed her background transitioning from developer to DevOps architect. She contributed to Chef development and created several Chef knife plugins. Aphale also discussed using Docker and Chef together to automate container management and deployment. She showed how to build a Docker image using Chef recipes and push it to a registry for deployment using Chef push jobs.
Docker has changed the way Configuration Management is done. And Chef can be Docker's best friend to bake your favorite Config!
This session will cover -
- Using chef containers
- Managing docker images using Chef
- Using Chef push jobs to run docker containers on nodes
- And most importantly - why Chef is needed to manage dockers and why it all cannot be done with "simple" docker files!

Telepresence allows developers to test applications locally that are deployed to Kubernetes clusters. It creates a network proxy between a local development environment and a pod running in the cluster, enabling local development and testing that reflects the cluster environment. Key features include deploying and debugging services locally without changing code in the cluster. The document provides an overview of Telepresence and examples for installing it and using it to swap a deployment for local development of both a Python HTTP server and Docker container-based application.

Docker for developers on mac and windowsDocker, Inc.
The whole Docker ecosystem exists today because of every single developer who found ways of using Docker to improve how they build software; whether streamlining production deployments, speeding up continuous integration systems or standing up an application on your laptop to hack on. In this talk we want to take a step back and look at where Docker sits today from the software developers point of view - and then jump ahead and talk about where it might go in the future. In this talk, we’ll discuss:
* Making Docker an everyday part of the developing software on the desktop, with Docker for Windows and Docker for Mac
* Docker Compose, and the future of describing applications as code
* How Docker provides the best tools for developing applications destined to run on any Kubernetes cluster
This session should be of interest to anyone who writes software; from people who want to hack on a few personal projects, to polyglot open source programmers and to professional developers working in tightly controlled environments. Everyone deserves a better developer experience.
Kubernetes is exploding in popularity right now and has all the buzz and cargo-culting that Docker enjoyed just a few years ago. But what even is Kubernetes? How do I run my PHP apps in it? Should I run my PHP apps in it ?
This document provides an overview of containerization basics using Docker. It defines key Docker terminology like images, containers, daemons, clients, and Docker Hub. It explains how to run a static website in a container, view running containers and container logs. It also summarizes common Dockerfile commands and how to build, push and pull images from a private registry.

Architecting .NET Applications for Docker and Container Based DeploymentsBen Hall
This document discusses using Docker containers to deploy .NET applications. It covers running a basic ASP.NET application in a Docker container, linking multiple containers together, and using tools like Docker Gen and Consul for service discovery. It also explores possibilities for the future like running SQL Server and Visual Studio in containers, and how Docker can help close the gap between development and production. The overall message is that Docker is a useful tool for deploying many types of applications, including those built on .NET.
This talk is a very quick intro to Docker, Terraform, and Amazon's EC2 Container Service (ECS). In just 15 minutes, you'll see how to take two apps (a Rails frontend and a Sinatra backend), package them as Docker containers, run them using Amazon ECS, and to define all of the infrastructure-as-code using Terraform.
This document provides instructions for setting up a Ruby on Rails development environment on Cloud9 using the suspenders gem. It describes installing Ruby 2.2.3, the suspenders gem, and its dependencies. It then explains how to create a new Rails project with suspenders and replace PostgreSQL with SQLite3. The document concludes by explaining how to launch the Rails server and install the simple_form gem for forms.
Docker: A New Way to Turbocharging Your Apps Developmentmsyukor
Docker is a platform for developing, shipping, and running applications. It provides containers that package applications and dependencies together allowing them to run seamlessly on any infrastructure. The document discusses Docker concepts like containers, images, and the Docker ecosystem. It also provides examples of using Docker with various applications and frameworks like PHP, Java, .NET, Nginx, and Apache. Managing Docker containers at scale can be done with tools like Kubernetes, Docker Datacenter, Rancher, and Prometheus for monitoring.

This session will cover the development & deployment of containerized ASP.NET Core 6 apps using Docker and Azure and architectural design & implementation approaches using .NET and Docker containers. The different services to deploy on Azure like Azure Container Registry, Azure Container instance, Azure Container Apps, and Azure Kubernetes Services as an orchestrator will be reviewed. We will also create the different resources and explore the different tools and properties if attendees prefer not to use Docker-Compose.yml. Then we will deploy our application that's based on Docker images using Azure App Service. And finally, we will configure continuous deployment for our web app with a webhook that monitors changes to the Docker image.

The Tale of a Docker-based Continuous Delivery Pipeline by Rafe Colton (ModCl...Docker, Inc.
The ModCloth Platform team has been building a Docker-based continuous delivery pipeline. This presentation discusses that project and how we build containers at ModCloth. The topics include what goes into our containers; how to optimize builds to use the Docker build cache effectively; useful development workflows (including using fig); and the key decision to treat containers as processes instead of mini-vms. This presentation will also discuss (and demo!) the workflow we’ve adopted for building containers and how we’ve integrated container builds with our CI.
Robert Barr presents on Kubernetes for Java developers. He discusses Quarkus, Micronaut and Spring Boot frameworks for building cloud-native Java applications. He provides an overview of Docker and how it can package applications. Barr then explains why Kubernetes is useful for orchestrating containers at scale, describing its architecture and key concepts like pods, deployments and services. He demonstrates running a sample application on Kubernetes and integrating with its Java client.
The document discusses two serverless computing platforms that support Swift - OpenWhisk and Fn.
OpenWhisk is an open source system that is event-driven, containerized, and allows chaining of actions. It is hosted on Bluemix but can be difficult to deploy elsewhere. Fn is container-native and deploys functions as containers communicating via standard input/output. Both allow simple Swift functions to be deployed and called remotely with REST APIs or command line tools. The document provides examples of writing, deploying and calling functions on each platform.
