PodCTL - Enterprise Kubernetes

SEASON 2 - Trailer

ABOUT THE SHOW:
It's been a few months, but it's good to back with our Kubernetes community. Since there are so many things happening around the Kubernetes community, and many people are new, we decided to move to a "season" format. Each season will include 8-10 episodes, around 12-15 minutes, that will allow the audience to progressively learn more about a specific focus area.

In Season 2, we're going to get back to the basics of Kubernetes, both from a technology and business perspective.

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 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 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.

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?

Topic 1 - Welcome back to the show. Let?s talk about some of the architectural concepts that will exist in OpenShift 4, and why decisions were made.

Topic 2 - OpenShift has always been a flexible/composable/modular platform. How does that evolve in OpenShift 4 (e.g. Operators, Platform + OS, etc.)? 

Topic 3 - OpenShift has evolved since the early 3.x days, when a lot of necessary things weren?t ?Kubernetes embedded? (install/upgrade tools, monitoring, scanning, visualization of resources, etc.). OpenShift has been moving to adopt the Kubernetes native elements as they mature (e.g. Prometheus). Can you talk about some of the new Kubernetes native capabilities coming in OpenShift 4 that people should start looking into? (e.g. CRI-O, Cluster-Version-Operator, Machine APIs)

Topic 4 - Let?s come back to the discussion of Operators. We heard alot about Operators for applications (e.g. databases), but are there uses for Operators for things that would be considered more platform-centric (e.g. storage, logging, service mesh, etc.)?

Topic 5 - There are some things happening in the public cloud that make it easier to manage nodes and scaling of nodes. Any interesting stuff coming to OpenShift 4 to help make those elements easier to manage?

Topic 2 - We decided to discuss ?policy? in Kubernetes. Where do you usually find that discussion begins. If I were to do a Google search, the Kubernetes site highlights ?Pod Security Policies? and ?Quotas?. 

Topic 3 - What types of tools do you see in production being used to apply and track policy within Kubernetes environments? 

Topic 4 - Grafaes and Kritis are often discussed around policy for ?securing Kubernetes software supply chain?. Are these types of projects focused on Kubernetes as a platform, or applications running on Kubernetes, with more of a focus on the CI/CD and Testing pipelines?

Topic 5 - There is a newer framework that?s starting to emerge, called ?Open Policy Agent?. What are some of the things that it is focused on?

Overview: Brian and Tyler talk about how existing application developers and PlatformOps teams can map existing applications and framework services into a more distributed set of services that run in containers on Kubernetes and OpenShift. 

Show Notes: 

Why Kubernetes is the New Application Server (blog)Kubernetes: Your Next Java Application Server (video and demo from @burrsutter)

We mentioned last week that we?re moving into the 3rd Era of Kubernetes (automated ops, automated apps), with the 2nd Era being about getting a broader set of applications on Kubernetes. Today we thought we?d talk about some design patterns, especially for anyone that?s transitioning from existing applications, and how some of those concepts map to the evolving Kubernetes eco-system.

Topic 1 - At the core of this statement about ?Kubernetes is the New Application Server? is three things: 

Some explanation about why containers are a useful packaging mechanism to avoid the difference between developer environments and production environments (package dependencies, etc.)How to mentally map between the more monolithic frameworks that are widely used today, and more distributed concepts that align more with Kubernetes and containers.Even within a language like Java, there are now variants (JakartaEE, Microprofile, Node, SpringBoot, etc.) and developers might not want to embed all functionality within the application, if it can be offloaded to platform services.

Topic 2 - It walks through the 10 elements that either map to Kubernetes, an OpenShift service, or emerging functionality in Istio (or maybe Knative)

Overview: Brian and Tyler talk about how well the industry has created or evolved Kubernetes-Native platforms and services. 

Show Notes:

Topic 1 - We?re more than 3yrs into Kubernetes, and almost at the 2yr anniversary of the 1st big CloudNativeCon / KubeCon in Seattle (we?ll be back again this year). So let?s ask a big question - how has the industry evolved to actually deliver Kubernetes-Native?

Topic 2 - What is Kubernetes-Native? 

Is it specific to containers?Is it specific to Kubernetes scheduling?Is it specific to Kubernetes extensibility?

Topic 3 - Was reading a report recently that separated the concepts of DevOps from PlatformOps. We know Developers experiences and expectations are never the same and always evolving. But should the PlatformOps side of things be standardizing on something Kubernetes-native? 

Topic 4 - What are some of the common things you?ve seen in the Kubernetes community (products, platforms, services) that have gained some traction, but aren?t really aligned to Kubernetes?

Show Overview: Brian and Tyler talk about how companies rationalize a Buy (or consume) vs Build decision for a Kubernetes platform or service.

Show Notes:

This show is somewhat free form, but it ultimately started with a listener question that asked:

"We run an internal Kubernetes platform in our centralized IT group, but some other developer groups also run their own Kubernetes platform. How do we convince them, or our management team, to bring other groups onto our platform to be both more cost effective and more collaborative with developers?"

How do we rationalize having one vs multiple platforms (cost, support, feature differences)?How do we communicate to internal groups about the capabilities of an internal platform?How do we stop thinking like an IT group and start thinking like a product team?How do we measure success of the platform?

Show Overview: Brian and Tyler talk about updates to Kubernetes v1.12
 
Show Notes:

Kubernetes 1.12 Updates (Official Kubernetes blog)What?s new in Kubernetes 1.12 (Red Hat CoreOS blog)OpenShift Commons Briefing on October 4 at 9 AM PT to discuss Kubernetes 1.12Operator Framework

Topic 1 - Kubelet TLS Bootstrap moves to GA - simplify how nodes are securely added/removed into a cluster. As an add-on,  server certificate rotation functionality moves into beta, and this will be tied in with Cluster Operators and Application Operators.

Topic 2 - Azure Virtual Machine Scale Sets (VMSS) and Cluster-Autoscaler is Now Stable

Topic 3 - On the network security front, two NetworkPolicy components graduate to GA: egress and ipBlock.

Topic 4 - Multi-Tenancy: In this release comes the ability to support priority on the various resource quotas via the new ResourceQuotaScopeSelector feature. This enhances the existing priority and preemption feature that was delivered in Kubernetes 1.11.

Topic 5 - CSI now supports the notion of topology awareness and this functionality moves to beta in Kubernetes 1.12. What this means is that stateful workloads can now have a conceptual understanding of where storage resources live, whether it be a rack, datacenter, availability zone, or region.

Topic 6 - Kubectl Plugins: With kubectl plugins, developers can engineer extensions to kubectl, which accommodate their administration scenarios, while not being baked into the core kubectl codebase. This is going to allow teams to develop and deliver kubectl functionality faster and in a more consistent manner. (example: OpenShift ?oc commands?) Topic 7 - Let?s discuss the upgrading process of Kubernetes (again).

Other noteworthy features:

Snapshot / restore functionality for Kubernetes and CSI is being introduced as an alpha feature. This provides standardized APIs design (CRDs) and adds PV snapshot/restore support for CSI volume drivers. Improvements that will allow the Horizontal Pod Autoscaler to reach proper size faster are moving to beta. Vertical Scaling of Pods is now in beta, which makes it possible to vary the resource limits on a pod over its lifetime. In particular, this is valuable for pets (i.e., pods that are very costly to destroy and re-create). Encryption at rest via KMS is now in beta. This adds multiple encryption providers, including Google Cloud KMS, Azure Key Vault, AWS KMS, and Hashicorp Vault, that will encrypt data as it is stored to etcd.

Show Notes:

Spark and AnalyticsJupyter NotebooksPackaging Applications on Kubernetes (PodCTL #37)

Topic 1 - From David - Is it possible to do a show about running Spark, Jupyter notebooks and analytical workloads on k8s?

Topic 2 - From Matthew - it would be interesting to hear your thoughts for how apps will be deployed and maintained in the future of OpenShift/kubernetes (covered in Eps.37 in late May).

Topic 3 - From Will - One thing I would still like to know about is how people secure their running kubernetes deployments.  Are people generally just exposing their ingress nodes to the open internet, or is it more complicated than that? I'm familiar with Nginx/Apache and modsecurity, and saw that OpenShift recently started supporting Nginx as ingress, and would like to know if anybody is using that as a WAF.

Topic 4 - From Walid - What storage available options are available for production use cases? and what diverse use cases are out there? e.g. stateful mostly,  how about trends in machine learning/AI, Big Data workloads not the conventional K8s workloads!

Show Notes:

Kubernetes 3rd Anniversary 

Google Cloud Services Platform (GCSP) - Hybrid and Multi-cloud application development stack, built on Kubernetes and Istio - custom-configured, enterprise-hardened, and delivered by Google.

GKE On-Prem - A core component of CSP, with GKE On-Prem, customers get the Google Kubernetes Engine (GKE) experience in their data center.  The first private cloud option for deployment is vSphere 6.5 in alpha release this fall and Google will continue to look at the hardware and other virtualization environments.  In a parallel statement, Cisco Hybrid Cloud for Google Cloud will be the first GKE-certified hybrid cloud platform, although any direct relationship to GKE On-prem is unclear.

Project Knative - (Knative on Github) it provides fundamental building blocks for serverless workloads in Kubernetes, empowering the creation of modern, container-based and cloud-native applications which can be deployed anywhere on Kubernetes. OpenShift + Knative (blog).

Istio 1.0 - Istio service mesh is now version 1.0, and available as a managed add-on to GKE, as well as being integrated into Google Stackdriver. PodCTL #23 - Microservices with Istio

Google Cloud Platform Marketplace (pre-announced) - Marketplace of packaged applications to run on GCP and Google Cloud services (e.g. Kubernetes) 

GKE Serverless Containers Add-On - Similar to AWS Fargate, Google announced an early-trial serverless infrastructure option to GKE , simplifying infrastructure operations management.

Show Notes:

Cloudability ?State of Cloud (2018)?DataDog - ?Surprising Facts about Real Docker Adoption?Digital Ocean ?Currents? (June 2018)CNCF Survey (June 2018)

Topic 1 - Lots of differences between these surveys, both in methodology and results:

Does the data come from surveys or actual monitoring? How do they classify various technologies (by project, by vendor, by cloud service, by both)? Do they include usage-based details?

Topic 2 - Would you prefer to see more vendor-usage data in these reports, or is it OK to just have generic usage data? Right now it?s sort of a mixed bag

Topic 3 - It?s (usually) never clear who is running these container environments. We see some survey data targeting developers, but not all of them explain (or know) which groups are running the container environments vs. consuming services.

Topic 4 - It?s interesting that none of these surveys highlight the location of companies/customers/users, since we know that certain geographic pockets of the world have very different usage behaviors than others.
