SHOW TOPICS:
Topic 1 - Since you work at PagerDuty, how does PagerDuty use PagerDuty?

Topic 2 - What are some interesting uses of PagerDuty you’ve seen out in the wild?

Topic 3 - You’ve built on call rotations. You’ve got your scars. One thing I’ve noticed is discussions about alert fatigue. Do you have any suggestions around how organization can better handle on call and alerting in general? (“Fight, Flight, or Freeze - Releasing Organizational Trauma”)

Topic 4 - DevOps at 10. For me, DevOps crossing into that double-digit year number seems to have increased awareness of it and its potential for orgs not embracing it. What have you seen in terms of organizations embracing DevOps? What are Matt’s highlights of DevOps after ten years?

Topic 5 - You're writing an article on SysAdvent website called “15 Ways to Make On-Call More Fun”; It’s supposed to be published around December 3rd. Watch https://sysadvent.blogspot.com/ for this year’s stuff.

SHOW: 72

SHOW OVERVIEW: Brian talks with Joe Fernandes (@JoeFern1, VP of Product Management, Red Hat Cloud BU) about Red Hat's experience with Kubernetes, innovating upstream and integrating products, OpenShift 4 cloud-like architectural changes, allowing developers to be productive, and new ways to create a better customer experience.

SHOW NOTES:

• OpenShift Commons - http://commons.openshift.org
• OpenShift Blog (Joe Fernandes) - https://blog.openshift.com/author/joefernandes/

SHOW TOPICS:
Topic 1 - Welcome to the show. Let’s start by talking about your experience at Red Hat in managing OpenShift. 

Topic 2 - We talk a lot about Kubernetes on this show obviously.  Tell us how you and the OpenShift product team first got involved with Kubernetes.

Topic 2a - Give the audience a sense of what it takes to build (and continue to maintain) not just a commercially-supported Kubernetes distribution, but all the on-going integrations to make it a production application platform. 

Topic 2b - What are some of the things needed to evolve a platform from “just running containerized apps” to one that is intelligent enough to manage many different types of applications? 

Topic 3 - There is always some Twitter chatter that Kubernetes is too complicated and nobody should run Kubernetes except the 3 major public cloud providers. What types of things has OpenShift needed to do to be able to run “like a managed cloud platform”?

Topic 4 - When you get “above” Kubernetes, you have to start thinking about how developers will interact with the platform. This is where there are a lot of opinions, and many new innovations/projects. How does OpenShift think about “building on the platform”?

Topic 5 - Part of “the cloud experience” is being able to gather information about how the platform is used, in order to make better product decisions. The public cloud does this behind the scenes for every customer. Can OpenShift do anything to help create better customer experiences?

SHOW: 70

SHOW OVERVIEW: Brian talks with Alexis Richardson (@monadic, CEO @weaveworks) about the emerging concepts and technology behind “GitOps”. 

SHOW NOTES:

• Gitops at Weave Works
• [video] GitOps - Git push all the things
• OperatorHub

SHOW TOPICS:

Topic 1 - Welcome to the show. Tell us about your background both at Weave and your involvement in the CNCF.

Topic 2 - Weave really started evangelizing this concept of “GitOps”. For anyone that isn’t familiar, walk us through the basics building blocks.  

Topic 3 - Git becomes the CMDB (single source of truth, single source for compliance). Developers push code (Git > CI/CD). CI/CD system builds containers and deploys to Kubernetes. What assumptions does this model make about the underlying infrastructure operations? 

Topic 4 - Let’s talk about the separation of interests between the CI system and the CD system and how this impacts security. 

Topic 5 - Let’s talk about the role of Operators in a GitOps environment. Operators (today) tend to be more focused on stateful applications, so how does this link into developer code?

SHOW: 67

SHOW OVERVIEW: Brian talks with Annette Clewett (@aclewett, Senior Architect @RedHat) and Travis Nielsen (@STravisNielsen, Senior Principal Software Engineer @RedHat) about software-defined storage, managing storage with Kubernetes, and how Rook is bringing the Operator model to storage systems like Ceph.

• Deep Dive: Rook (video) - KubeCon 2018
• Ceph on OpenShift with Rook (video) - Commons Gathering 2019
• Rook Channel on Slack

SHOW TOPICS:

Topic 1 - Welcome both of you to the show. Before we get into discussing Ceph and Rook, can you tell us about your background around these projects? 

Topic 2 - One of the most frequent requests we get from listeners is to discuss how to integrate (and manage) storage into OpenShift/Kubernetes environments. Let’s talk about storage needs for OpenShift/Kubernetes infrastructure (masters, logging, monitoring, etc.) vs. storage for applications. 

Topic 3 - Help us understand the difference between a storage manager like Rook and a storage system like Ceph. Where does one start and the next one stop? 

Topic 4 - Rook now uses the Operator pattern for managing underlying storage systems. How does the Operator technology help make managing (and lifecycling) storage easier or more robust? 

Topic 5 - As you talk to users of Ceph and Rook, what are some of the best practices that you’re seeing them implement?

SHOW: 66

SHOW OVERVIEW: Brian talks with Marc Boorshtein (@mlbian, CTO at Tremolo Security) about trends in Kubernetes security, and how to think about the Kubernetes Extended Authentication Model.

SHOW NOTES:

• Try OpenShift 4 - http://try.openshift.com
• Beyond RBAC in OpenShift – Open Policy Agent
• OpenShift Commons Briefing: Securing OKD at Multiple Layers
• Kubernetes Security 

SHOW TOPICS:

Topic 1 - Welcome back to the show. Your focus is on security. What’s one new thing that’s really interesting to your right now, and what’s one “mundane” thing you’re seeing all the time that isn’t getting enough discussion? 

Topic 2 - A few weeks ago we talked with John Osbourne about “Kubernetes Policy”. This is very different than “Authentication” or “Authorization”. For people that don’t live around security, can you help us understand the difference between policy and the things that make up AAA (Authentication, Authorization and Accounting)?

Topic 3 - You and I were talking a few months ago at OpenShift Commons Gathering in London about “the Kubernetes extended authorization model”, and I wonder if you could elaborate on that a little bit. 

Topic 4 - What are some of the areas where you feel like there isn’t enough awareness, especially for production environments, between policy and AAA models (e.g. Kubernetes elements vs. user-level elements)?

Topic 5 - Give us a quick set of thoughts on how any of this changes if we start doing multi-cluster or Federation.

SHOW: 65

SHOW OVERVIEW: Brian talks with Paul Morie (@cheddarmint, Sr. Principal Software Engineer @RedHat, Reviewer/Approver of Federation v2) about the evolution of multi-cluster and Federation v2 in Kubernetes.   

SHOW NOTES:

• Try OpenShift 4 - http://try.openshift.com
• Kubernetes Federation v2 - https://github.com/kubernetes-sigs/federation-v2
• Kubernetes Federation v2 on OperatorHub - https://operatorhub.io/operator/alpha/federation.v0.0.6
• Kubernetes Federation v2 on OpenShift 3.11 - https://blog.openshift.com/kubernetes-federation-v2-on-openshift-3-11/

SHOW TOPICS:

Topic 1 - Let’s start with some basics. The differences between “Federation” and “Multi-Cluster”?

Topic 2 - What are the basic functionality that needs to be in place to federate more than 1 cluster together (authentication, registry, cluster registry, network routing, etc.)

Topic 3 - What are some of the mechanisms that help determine which cluster a container should run?

Topic 4 - Is the current design intended to handle applications that span clusters, or is the expectation that apps live in a single cluster? What about deploying the same app to multiple clusters?

Topic 5 - For more advanced capabilities, such as intelligence to know where to dynamically place an application, would that be something that’s within Kubernetes, or any external service?
