Brian and Tyler talk with Clayton Coleman (@smarterclayton, Lead Kubernetes Architect) and Derek Carr (@derekwaynecarr, Kubernetes Lead Engineer) about the Kubernetes development process, the role of SIGs, the process for deciding what gets included in a release, as well as an in-depth discussion about the extensibility of Kubernetes 1.8

An Overview of Project "Istio"

Topic 1 - Welcome to the show. Both of you are top contributors to Kubernetes, both also lead (or co-lead) some of the SIG/Working group. Can you give us a sense of your community involvement from a contributor and leader perspective?

Topic 2 - Derek, you're on the nomination list for the Kubernetes Steering Committee. Chris Aniszczyk mentioned it a couple weeks ago, but what does that group do that’s different than SIGs? 

Topic 3 - When there are 100s of contributors and many different focus areas, what is the process for deciding what’s included or prioritized or dropped from a specific release?

Topic 4  - Kubernetes 1.8 has a mix of Alpha, Beta and Stable features. What do you see as the key focus areas in this release? (e.g. RBAC, CRI-O, etc.)

Topic 5 - How does Kubernetes look at the explosion of “tools” around core Kubernetes (deployers, application templates, application frameworks) and when to make those parts of the project or keep them separate?

PodCTL #7 - Digging into Kubernetes 1.8

Brian and Tyler talk with Jeremy Eder (@jeremyeder, Senior Principal Software Engineer at Red Hat) about the Kubernetes Resource Management Working Group, scaling Kubernetes environments, extending Kubernetes for high-performance workloads (HPC, HFT, Animation, GPUs, etc.), testing at scale and how companies can get involved.

PodCTL #8 - Managing High Performance Workloads

Overview: Brian and Tyler talk about Kubernetes Networking and Kubernetes Storage. 

Show Notes:
- Kubernetes Network Plugins
- Kubernetes and Storage
- Container Native Storage

Topic 1 - Let’s talk about the challenges of networking with containers and some of the ways that Kubernetes addresses these challenges.

There’s lots of different ways to network containers together. 
- Kubernetes does some basic networking (by default), and then there are add-on options for more complex, secure scenarios.
- The role of DNS in Kubernetes networking (services, etc.) 
- Kubernetes network plugins (CNI: container network interface) 
- Ingress and Egress Routes, Services, Load Balancing 
- Network Policy (fine-grained traffic control)  

Topic 2 - Let’s talk about the challenges of storage with containers and some of the ways that Kubernetes addresses these challenges.

There’s definitely a misperception that containers should only be used for stateless applications. 
- Containers are (primarily) Linux, and Linux has well known concepts about how to interact with persistent storage. 
- Containers need a way to interact with persistent storage in a model where it can be dynamically allocated. 
- Kubernetes storage plugin proposal (CSI: container storage interface)

PodCTL #9 - Unclogging some Kubernetes Plumbing Issues

Overview: Brian and Tyler talk with Paul Morie (@cheddarmint, Principal Software Engineer @RedHat, Lead of Kubernetes Service Catalog SIG) about the evolution of the Open Service Broker API, integrating with external services, the role of Service Brokers, and use-cases to expand Kubernetes applications.

Open Service Broker API

Topic 1 - Welcome to the show. Before you got involved in the Service Catalog SIG, you worked on several other aspects of Kubernetes (security, etc.). Tell us about some of the things you’re been involved with?

Topic 2 - Let’s go back to when the Open Service Broker API was announced. What was the purpose and how did it evolve to where it is now?

Topic 3 - What are the basics of how the Service Broker / Service Catalog interacts with applications on Kubernetes and 3rd-party services? 
Example: How do we think about user/password/security credentials to a database?
Example: Is the Service Broker in the data path as well as the control path?
Example: Where would traffic auditing functions happen?
Topic 4 - We saw a demo of the Service Catalog/Broker at Red Hat summit during an announcement with AWS, where is showed AWS services as part of the catalog. Previously, we’ve seen the CF Service Broker interact with Google or Azure services. Is the relationship between the broker and cloud-services “cloud specific”, or will things be interchangeable at all?
Topic 5 - Beyond public cloud services, what other types of things might be interconnected or managed via the Service Broker?

PodCTL #10 - Service Catalog All the Things

Overview: Brian and Tyler talk Julius Volz (@juliusvolz, @PrometheusIO co-founder, promcon.io founder) about the challenges that Prometheus solves, how it does monitoring and interacts with other systems, how it works with Kubernetes, and common-use cases and patterns.

Topic 1 - You created Prometheus a couple years ago at SoundCloud. What were the core challenges you were trying to solve?
Topic 2 - For people new to Prometheus, what does it do (at a basic level) in terms of monitoring containers and applications?
What can it monitor?
What can it trigger other systems to do? 
Topic 3 - Prometheus is now part of CNCF. Is it a native Kubernetes service, or a sidecar application for containers, or a broad service that just runs on Kubernetes?
Topic 4 - What are the basic things that most people use Prometheus to monitor for?  What are a few complex use-cases?  (application types, application frameworks, usage-patterns, etc.)

PodCTL #11 - An Introduction to Prometheus

Brian and Tyler talk with Dan Walsh (@rhatdan, Consulting Engineer at Red Hat, container team lead) and Mrunal Patel (@mrunalp, Principal Engineer at Red Hat, OCI/runc maintainer) about the evolution of containers with Kubernetes, the creation of CRI-O, and the focus on container security and stability. We also discussed emerging projects like Skopeo, Buildah, Intel Clear Containers and Grafeas.
