The keynote presentation discusses the evolution of the TOC and its role in guiding technical decisions to improve the way the cloud native community is served.
  • Continuous Improvement (CI) is not a new concept and is based on continuous improvement of working practices and personal efficiency.
  • The TOC has continuously evolved to meet the scale of project adoption and provide value to the cloud native community.
  • The TOC represents 10 companies, including 3 end users, and members work in small, medium, and large companies from 4 different countries and 2 continents.
  • The TOC's mission is to take Cloud native Computing everywhere from the desktop to the data center to the edge.
  • The TOC guides technical decisions through open governance and transparency, technical evolution, and interoperability.
  • The TOC shepherds projects through the three stages of the CNCF: sandbox, incubation, and graduation.
  • The TOC created technical advisory groups (TAGs) to manage the many projects and technical areas.
  • TAGs cover a wide variety of areas, including security, storage, and disaster recovery.
  • The TAGs collaborate with projects on security reviews, supply chain security, and storage architectures.
  • The TOC is constantly looking for ways to improve processes and listens to feedback to ensure positive and sustainable growth for the future.

The Cloud Native Chasm: Building a Secure High-Impact Project
  • Cloud native projects require a guide to navigate the complex and massive landscape
  • Security is often not added on day one and needs to be considered after understanding the project's goals and environment
  • Building a secure high-impact project requires help and a security mindset from all contributors
  • Projects need to plan for changing uses and new use cases that may reveal inherent weaknesses or invalid security assumptions
  • Public discussion, clearly documented decisions, and well-defined roadmaps with clear outcomes are necessary for building and securing projects
  • Participating in security reviews and assessments and joining security-focused groups can help reframe thinking and create more secure structures

The presentation discusses the resources and services available for projects in the CNCF, including communication platforms, security assessments, and white paper assistance.
  • Projects in the CNCF have access to various resources and services, including mailing lists, meeting platforms, and security assessments.
  • The CNCF can assist with creating white papers and case studies for projects.
  • Sandbox projects can benefit from smaller assessments, such as documentation assessments.
  • Requests for resources and services can be made through the CNCF service desk.
  • Marketing for sandbox projects is limited by CNCF policy.

The presentation discusses the importance of governance in open source projects and provides guidance on how to establish clear expectations, define project scope and values, and define roles and responsibilities for contributors.
  • Governance is about alignment and collaboration within a community.
  • Setting clear expectations helps facilitate alignment.
  • Defining project scope and values is important to avoid misunderstandings.
  • Defining roles and responsibilities for contributors is crucial for effective governance.
  • The CNCF provides resources and guidance for projects to establish governance, but it is up to individual projects to build their own communities and adopters.
  • The CNCF prefers the use of Apache2 for code and Creative Commons for documentation, but exceptions can be made with approval from the governing board.

Overview of various Kubernetes-related projects and their use cases
  • Projects include Volcano, K3s, Confidential Computing, Crosslit, Cuver, Vorteil, Box, Rootless Containers, and Trial
  • Use cases range from managing Kubernetes clusters at the edge to auto-scaling based on events to creating custom operating systems for specific workloads
  • Volcano is for scheduling resource-intensive workloads, K3s is a lightweight Kubernetes distribution for the edge, and Confidential Computing provides encryption and security for running workloads without revealing information to cloud providers
  • Cuver allows for managing virtual machines with Kubernetes, Crosslit enables running web assembly modules with Kubernetes, and Vorteil creates custom operating systems for specific workloads
  • Box is a Docker container that acts like a VM, Rootless Containers allows running containers as root users without compromising the host, and Trial is a container registry with a focus on high performance and P2P distribution

The talk explains the lifecycle of Custom Resource Definitions (CRDs) and the challenges of versioning them. It provides insights on how to upgrade CRDs seamlessly, with zero downtime and backwards compatibility.
  • CRDs are used to extend Kubernetes and as projects grow, the definitions of the resource start to evolve and may completely change, requiring versioning of CRDs
  • Versioning of CRDs can be tough as end users need to be provided with seamless upgrades, zero downtime and backwards compatibility
  • There are two views of CRD versioning: server version and stored version
  • There are two conversion strategies: last mile change and full conversion
  • The conversion package simplifies conversion functions between API versions
  • The storage version migrator component bumps up existing objects to the new desired storage version
  • Lossless conversion is followed where users can roll back to the older version
  • Annotations of the field of the CR are used to store functions which lose data between versions
