Show Overview: Brian and Tyler talk about the core capabilities of container registries, how they interact with Kubernetes and CI/CD pipelines, and some design and security considerations for architects.
 
Show Notes:

• Twistlock $33M in Funding - Container Security
• Project Clair - Vulnerability Scanning
• Quay Container Registry
• Red Hat OpenShift Registry

Topic 1 - Let’s start with the basics. What does a container registry do? Is it just a glorified FTP server?

• Serves and stores container images 
• Has a storage backend that should be replicated (somewhere) - usually Object or NFS 
• May have the ability to scan images for vulnerabilities or digitally sign image

Topic 2 - What are the typical interactions that a container registry has with elements of Kubernetes (e.g. Deployments, Kubernetes masters) and elements around Kubernetes (e.g. CI/CD pipeline)?

Topic 3 - How do things like scanning and signing fit into container registries? Or should that function reside somewhere else?

Topic 4 - What sort of design considerations should architects consider for the container registry?

• Where is it physically located? 
• How to handle redundancy or replication? 
• How to scope out performance? 
• Multi-Tenancy or Groups?

Show Overview: Brian and Tyler talk about how Kubernetes has evolved over the last three years, from the community to the technology to new things coming down the road.

Show Notes:

Kubernetes 3rd Anniversary

Topic 1 - Let’s start with people and community. How have you seen the Kubernetes community evolve over the past 3 years? What’s working well, and where have there been struggles?
Topic 2 - Technology-wise, where would you place the highlights for Kubernetes? This could be the technology itself, or how it’s been adopted, or maybe just the overall architecture.
Topic 3 - Technology-wise, where would you place the challenges for Kubernetes? This could be the technology itself, or how it’s been adopted, or maybe just the overall architecture.
Topic 4 - There seems to be a new chorus of pushback on Kubernetes, around the complexity of managing complex environments (e.g. DR for Stateful apps) and the serverless fans. Do you see this as a problem, a distraction, or valid criticisms?
Topic 5 - What do you see making a lot of headlines vs. being the important things for end-users to focus on for the next year?

Show Overview: Brian and Tyler talk about Kubernetes 3rd Anniversary, Istio, Knative, and the Kubernetes-related announcements from GoogleNEXT2018.

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 Overview: Brian and Tyler talk about the new Kubernetes 1.11 release, the new features and capabilities.
 
Show Notes:

• Kubernetes 1.11 Release
• Kubernetes 1.11 - Custom Resources, Pod Priority & Preemption, and more
• Kubernetes Ramps Up Custom Resource Definitions

Topic 1 - Let’s review for anybody that’s a new listener how the Kubernetes community identifies the maturity level of features and how they should consider interpreting those classifications.

Topic 2 - Kubernetes release usually have a few new GA features, and then lots of Beta or Tech Preview features. What were the highlights of this release for you, or some of the core areas you suggest people focus on?

Topic 3 - Let’s walk through some of the most mentioned capabilities:

• IPVS-Based In-Cluster Service Load Balancing Graduates to General Availability 
• CoreDNS Promoted to General Availability
• Dynamic Kubelet Configuration Moves to Beta 
• Custom Resource Definitions Can Now Define Multiple Versions 
• Resizing Persistent Volumes using Kubernetes

Show Overview: Brian and Tyler talk about a number of data surveys that have recently been published about container usage, Kubernetes usage, and several other cloud trends.

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.

Show Overview: Brian and Tyler talk some of the basics, lessons learned and other things people could use to “fast-track” what they need to be successful with Kubernetes.
 
Show Notes:

• Learn Kubernetes
• Learn OpenShift
• Learn Containers (with Docker)
• Learn Containers (without Docker)
• Learn Prometheus

Show Premise:
Kubernetes community now has 10 releases (2.5yrs) of software and experience. We just finished KubeCon and Red Hat Summit and we heard lots of companies talk about their deployments and journeys. But many of them took a while (12-18) months to get to where they are today. This feels like the “early adopters” and we’re beginning to get to the “crossing the chasm” part of the market. So thought we’d discuss some of the basics, lessons learned and other things people could use to “fast-track” what they need to be successful with Kubernetes.
 
Topic 1 - What are the core skills needed for a team that manages/runs/interacts with a Kubernetes environment?

• Ops Skills 
• Dev Skills 
• Compliance Skills / Security Skills

Topic 2 - What has significantly changed in the Kubernetes world since 2015/16 to today that people should consider taking advantage of?

• Persistence 
• Immutability 
• Operators 
• Native tools vs. Config Mgmt tools 
• Storage

Topic 3 - What do you consider “still hard” and should probably justify more early effort?

• Security? 
• Storage? 
• Monitoring? 
• Being overly precise about capacity planning?

Topic 4 - What patterns have you seen from successful deployments and customer behaviors?
