Phil Estes is a senior technical staff member at IBM who is involved in open source software including Linux, containers, and cloud technologies. He discusses his work contributing to Docker and the Open Container Initiative (OCI). The OCI is a Linux Foundation project that aims to create open standards for container runtimes and image formats. Estes helped bring features like user namespaces to Docker and helped design the multi-platform image specification. He also discusses runc, an OCI-compliant runtime that is used as the backend for Docker and CloudFoundry containers. Estes believes runc can continue to drive innovations in container features and implementations on different platforms and architectures.
OSCON: Advanced Docker developer workflows on Mac OS and WindowsDocker, Inc.
with Anil Madhavapeddy and Richard Mortier
Most developers use a Mac or Windows host to develop Docker Linux containers. This normally requires the installation of a Linux virtual machine as well as a complicated setup that includes a local networked filesystem for sharing data between the host and the Linux container, including UID mapping and case sensitivity, with inotify often being unreliable into the container; replicating Linux networking configuration locally to reflect the structure of the deployed microservices on the local laptop; and maintaining a separate Linux virtual machine and hypervisor such as VirtualBox, leading to heavyweight resource usage on a developer laptop.
Anil Madhavapeddy and Richard Mortier outline various methods to make using Docker on a Mac OS or Windows laptop as transparent as possible to the developer, including build scenarios from the conventional (Compose-based web stacks) to the deep end of systems (unikernel compilation) to the multi-CPU architecture (cross-compiling ARM containers on a normal Mac or Windows host).

1. Justin Cormack discussed using modern programming languages like Lua and Rust to build system software like networking drivers and TCP/IP stacks.
2. He argued that new high performance hardware requires rethinking system software design with microservices and libraries instead of large monolithic kernels.
3. Projects like Snabb and MirageOS are building network drivers and full TCP/IP stacks using languages like Lua and OCaml to take advantage of features like foreign function interfaces and garbage collection.
OSCON: Unikernels and Docker: From revolution to evolutionDocker, Inc.
with Richard Mortier and Anil Madhavapeddy
Unikernels are a growing technology that augment existing virtual machine and container deployments with compact, single-purpose appliances. Two main flavors exist: clean-slate unikernels, which are often language specific, such as MirageOS (OCaml) and HaLVM (Haskell), and more evolutionary unikernels that leverage existing OS technology recreated in library form, notably Rump Kernel used to build Rumprun unikernels.
The document discusses the current status of Docker on Windows. It begins with an introduction of the presenter and then provides an overview of Windows containers and how they work using lightweight virtualization and namespaces.

Clarity About Container Orchestration for a Developing MarketThe New Stack
Presenting at the April 2016 Container Camp, Alex Williams reported on the findings of a survey about container orchestration. There appears to be agreement that container orchestration includes cluster management, service discovery and scheduling functionality. Kubernetes, Docker Mesos and AWS ECS are the leading technology options. Ansible gets mentioned more than would be expected.
Container orchestration is a method for automating the deployment, scaling, and management of containers. It provides capabilities like fault tolerance, scalability, and efficient resource usage through tools that schedule container placement, update containers in batches, and manage resources. Key concepts include the cluster, control plane, data plane, orchestrator, services, tasks, and containers. Popular orchestration systems are Docker Swarm and Amazon ECS, which automate deploying applications on clusters, scaling, routing, updates, and resilience.
AtlasCamp 2015: The age of orchestration: From Docker basics to cluster manag...Atlassian
Nicola Paolucci, Atlassian
Containers hit the collective developer mind with great force the past two years and created a space of fervent innovation. Now work is moving towards orchestration. In this session we'll cover an overview of the container orchestration landscape, give an introduction to Docker's own tools - machine, swarm and compose - and show a (semi)live demo of how they work in practice.
- Docker can be integrated with CloudStack in several ways, including running Docker in CloudStack virtual machine guests, packaging CloudStack as Docker containers, and using Docker orchestrators to manage containers.
- CloudStack could potentially be re-architected to run its components in Docker containers and use Docker networking for isolation, with an orchestrator like Mesos or Kubernetes managing the CloudStack application.
- There are open questions around whether CloudStack or other orchestrators should schedule virtual machines or containers as the primary compute resource in a private cloud data center.
This document provides an overview of Kubernetes, an open-source system for automating deployment, scaling, and management of containerized applications. It describes Kubernetes' architecture including nodes, pods, replication controllers, services, and networking. It also discusses how to set up Kubernetes environments using Minikube or kubeadm and get started deploying pods and services.

Kustomize is a Kubernetes native configuration management tool that allows customizing application configurations without templating. It takes over existing application manifests and is built into the kubectl command. Kustomize introduces an overlay pattern to customize resources through a kustomization file. Other configuration tools like Helm have template languages that can be ugly due to templating and conflict with other tools, while Kpt automates editing but requires functions for transformations. Kustomize aims to provide a simpler way to customize configurations and can integrate with tools like ArgoCD. Challenges include dealing with incompatible upstream changes and difficulties reviewing pull requests.
Slides from Daniel Figucio, Field CTO at Github APAC from his talk at Wellington DevOps Group on 6 September, 2022

Adopting this modern approach to software development can be transformative—enabling collaboration and fostering the creation of high quality code. But understanding the principles, and potential challenges, is critical to success.
Many companies use the word “innersource” to describe how their engineering teams work together on code. Innersource is a development methodology where engineers build proprietary software using best practices from large-scale open source projects, like Kubernetes or Microsoft’s Visual Studio Code.
Large-scale open source projects require coordination and teamwork across thousands of contributors. The most successful ones are driven by a vision for their future, in addition to day-to-day user needs: speed, reliability, and functionality. The scale at which these operate can teach us a few lessons—and help your business build better software, faster using innersource.
An OpenShift Migration: From 3.9 to 4.5Everett Toews
The document summarizes a migration from OpenShift 3.9 to OpenShift 4.5. The plan involved building a proof of concept, building test clusters, communications, performing a cutover, validating the new clusters, and decommissioning the old clusters. There were some initial challenges around VMware and networking configurations, but the migration went smoothly overall. Going forward, the organization will focus on upgrades, new technologies like Tekton and service mesh, and ensuring a seamless experience for end users.
The document summarizes key topics from the Cloud Native Summit conference, including:
- Distributed tracing and Zipkin, which allows visibility into request paths and troubleshooting of latency issues. Zipkin is an open source distributed tracing system.
- Production ready Kubernetes clusters on Catalyst Cloud, which provides security, high availability, and scalability for containerized applications.
- Building serverless applications at scale using services like AWS Lambda, and addressing concurrency bottlenecks when autoscaling.
- Istio service mesh, which provides control of traffic policies, authentication, and observability across distributed services through its control plane and sidecar proxy architecture.
- GitOps for infrastructure as code deployments on Open
This document discusses DevOps principles and practices. It states that DevOps is not just developers and operators working together, but rather focuses on culture, automation, learning and sharing through practices like continuous integration, infrastructure as code, and monitoring. Implementing DevOps principles can increase quality, confidence, and velocity by prioritizing customer feedback and continuous delivery.
