The document summarizes key points from Day 1 of DockerCon. It discusses Docker's mission to build tools for mass innovation and how they are taking an incremental approach to reinventing the programmer's toolbox. New tools like Docker, Docker Compose, Docker Machine, Docker Swarm, Docker Networking plugins and Notary were introduced to help solve problems around runtimes, packaging, service composition, machine management, clustering, networking and security. Docker is also donating runC to the Open Container Project and forming the Open Container Project to establish open standards around container formats and governance.

This document discusses Docker Registry API V2, a new model for image distribution that addresses limitations in the previous V1 API. Key changes include making layers content-addressable using cryptographic digests for identification and verification. Images are now described by manifests containing layer digests. The registry stores content in repositories and no longer exposes internal image details. Early adoption shows V2 providing significantly better performance than V1 with 80% fewer requests and 60% less bandwidth used. Future goals include improving documentation, adding features like pull-through caching, and developing the Docker distribution components to provide a foundation for more advanced distribution models.

Docker provides an open platform consisting of Docker Engine software and Docker Hub services to build, ship, and run distributed applications across any infrastructure. The platform includes tools to containerize any application and its dependencies into portable packages that can run on any infrastructure from physical and virtual machines to public and private clouds. This allows applications to be quickly and easily deployed and migrated between different computing environments.

This document summarizes the key events and announcements from Day 1 of DockerCon. It highlights the large number of attendees, keynotes from Red Hat executives, and the official launch of Docker Engine 1.0 and Docker Hub 1.0.

The solutions discussed are using Swagger to declaratively describe APIs, open sourcing tools to engage the community, and maintaining API consistency. It also addresses handling multiple release scopes by using custom fields in the Swagger specification.

The document discusses the promises and myths of new distributed computing platforms like Docker and Weave. It identifies 8 myths of how these new platforms position themselves, such as the idea that applications can be independent of the operating system or that platforms are better at designing apps than developers. The reality is that by "turning back the clock 30 years" to older distributed computing approaches, many of the skills and tools developers already use can apply when building apps on new platforms like Docker and Weave.

Lightweight virtualization uses container technology to isolate processes and their resources through namespaces and cgroups. Docker is a container management system that provides lightweight virtualization. Baidu chose Docker for its BAE platform because containers provide better isolation than sandboxes with fewer restrictions and lower costs. Docker meets BAE's needs but was improved with additional security and resource constraints for its PAAS platform.

Eric Feliksik's Slides from his DockerCon presentation: Nerdalize is a Dutch start-up that provides affordable and green computing power with an innovative approach. We heat living rooms with CPUs, as high-performance computer hardware is fit into a beautiful design radiator. While home owners heat for free, a massive distributed compute infrastructure becomes available. In this talk, we give a detailed overview of how Docker, Rancher and other tools in the ecosystem enable us to leverage such a highly distributed micro-datacenter architecture.

WaveMaker Webinar: Cloud-based App Development and Docker: Trends to watch out for in 2015 - http://www.wavemaker.com/news/webinar-cloud-app-development-and-docker-trends/ CIOs, IT planners and developers at a growing number of organizations are taking advantage of the simplicity and productivity benefits of cloud application development. With Docker technology, cloud-based app development or aPaaS (Application Platform as a Service) is only becoming more disruptive − forcing organizations to rethink how they handle innovation, time-to-market pressures, and IT workloads.

We are on the cusp of a new era of application development software: instead of bolting on operations as an after-thought to the software development process, Kubernetes promises to bring development and operations together by design.

Building large scale apps traditionally has traditionally meant building large monolithic apps to handle everything. In the new age of the cloud and on premise data centers, increasingly the world is looking to containers and microservices. This allows flexibility and agility. Individual teams can choose the tools they need and be assured they'll work in the environment they want. And it also has implications for how we do developer relations, making it easier to deploy samples without worrying about environment. This session will look at microservices and how they are changing both the enterprise, and our work in developer relations.

How to build "AutoScale and AutoHeal" systems using DevOps practices by using modern technologies.

Karthik Gaekwad gave a talk about his experience transitioning from devops to "dadops" as he prepares for the birth of his first child. He discussed how many aspects of parenting, such as learning on the job, sharing resources with other parents, automating tasks, and monitoring metrics are similar to the devops mindset of continuous learning, collaboration, automation, and measurement. He also humorously compared the challenges of on-call support for devops to being on-call as a parent.

Writing secure applications in a new language is challenging. Here are some tips to help get you started for writing secure code in golang. Presented at Lascon 2015

In this presentation, I talk about Docker and Container Management issues and solutions provided for them via StackEngine. I gave this talk at the CloudAustin meetup for the 12 Clouds of Christmas 2014.

There are many facets of devops, and we will spend our time in this presentation focusing on collecting and using metrics (business, application, system, etc.) and building a metrics driven culture in organizations. We will define how we have seen devops progress in our organizations and how we’ve realized that different teams in our organizations can find common ground when teams (who have different roles) can work well together when they use metrics as the common language. Karthik will talk about how we are using the principles from the Lean Startup to define our development cycles, sprints and using metrics to quantify how successful the products we are trying to come out with in R&D. Initially we started practicing devops on the dev and ops side of the house but realized this was still a black box to the business side of the house, so we pivoted to what our business actually understood, and that was metrics; today, we focus more on metrics (business and system level), and can fail or succeed fast to achieve our business goals faster than before. Ernest will go into detail on how a large, mature SaaS organization uses metrics in conjunction with distributed agile development and DevOps to guide their development at scale. How much a product is used, how much each feature is used, and how much value each user gets out of it are key drivers for a business strategy - and it’s all information that’s emitted by a system. He'll show how large companies have invested time in collecting and using these metrics to guide their decisions and influence their culture.

The document is recruiting for help in the "talent war" happening in Austin, Texas where there is high demand for tech talent. It promotes Austin as a great place for young entrepreneurs and notes the low cost of living where homeownerships is possible. It encourages keeping the DevOps community vibrant in Austin by attending local meetups, coworking, and using buddy systems to bring different roles together. Coffee shops, coworking spaces, and happy hours are recommended for networking.

Karthik reflects on the conferences and meetups they attended in 2013 related to cloud computing, DevOps, and Agile methodologies. They summarize key takeaways from each event, including that SXSW had too many hipsters, Velocity emphasized frontend JavaScript development, DevOpsDays discussed infrastructure as code and continuous integration, and AWS Re:Invent was worthwhile despite being a vendor event. They also highlight local Austin meetups and recommend speakers to listen to.
