Containers: four things to consider

•

Bridget Kromhout discusses four things to consider about containers: 1) They aren't new technology but are different than previous implementations, 2) They aren't just for development and can be used for production environments, 3) They require rethinking architecture to take advantage of their benefits, and 4) Containers cannot be ignored as their use continues to grow.

Docker opens the Doors for IoT

Dieter Reuter

A talk given at All Thing Open's Open Source 101 event at NC State University, Raleigh, North Carolina on Saturday, 17th February, 2018. This talk covered some interesting history lessons of the Docker open source project and inter-vendor tensions. If you were not at this talk do not read intent into these slides as this was truly an attempt at a "blame-free" post-mortem of the important topics of open source, governance, and foundations as it related to the extremely popular Docker open source project.

An Open Source Story: Open Containers & Open Communities

Phil Estes

The Moby Project is a collaborative open-source project launched by Docker, Inc. to promote software containerization. The Moby Project provides a "lego set" of components that can be assembled into custom downstream container systems such as Docker. Akihiro Suda, a maintainer of Moby, Moby BuildKit, and containerd, shows how the community has been collaborating in the Moby Project. He also shows how the Moby Project relates to Docker, OCI, and CNCF projects such as Kubernetes. http://events.linuxfoundation.org/events/open-source-forum

Kubernetes has rapidly grown to support many container runtime formats. In this talk, I'm presenting all the alternatives you have to run your applications in kubernetes, and will present CRI-O which is steadily becoming a replacement to run your Docker containers on production. And since you will no longer have a docker daemon on your hosts, how will you build now your containers? I'll talk about all the options you have in this new world of Dockerless containers.

Build and run applications in a dockerless kubernetes world - DevConf India 18

Jorge Morales

Containers have become integral to every phase in the lifecycle of application development. Production grade orchestration tools such as Kubernetes have been built to manage them and container platforms like Docker are becoming commonplace in both testing and development. Web tutorials on how to build and manage simple Docker images abound! But what are containers exactly and why have they become so essential to the DevOps ecosystem? This talk is for those curious minds who want to look below the surface and really understand the mechanics of a technique that has actually been around longer than you may think. Where did Docker come from? What about other projects in the container ecosystem - are there alternatives? What does a Docker image actually look like on the filesystem? How do Docker image layers work? What are cgroups? How are system resources allocated and managed and are there any gotchas that you should be aware of? What about security? How can JFrog Container Registry help me manage my Docker images? After this talk, you will have a solid understanding of the what, how & why of virtualized container technology.

I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

You’ve heard good data matters in Machine Learning, but does it matter for Generative AI applications? Corporate data often differs significantly from the general Internet data used to train most foundation models. Join me for a demo on building an open source RAG (Retrieval Augmented Generation) stack using Milvus vector database for Retrieval, LangChain, Llama 3 with Ollama, Ragas RAG Eval, and optional Zilliz cloud, OpenAI.
