episode 2: The good, the bad and the ugly of templating YAML in Kubernetes, with Alexander Block
In this KubeFM episode, Alexander Block delves into the intricacies of Kubernetes templating and deployment tools, sharing his journey from frustration with existing solutions to creating his tool, kluctl.
Alex also discusses the challenges and solutions in Kubernetes templating and deployment, emphasizing the need for more adaptable tools in the Kubernetes ecosystem...
Kubernetes needs a Long Term Support (LTS) release plan, with Mathew Duggan
With the rapid pace of the cloud-native ecosystem, staying current with Kubernetes updates and managing upgrades becomes a daunting task for many organizations.
In this KubeFM episode, Mat discusses the necessity of long-term support for Kubernetes and explores the intricacies of managing Kubernetes upgrades in a fast-evolving landscape...
episode 10: Clusters are cattle until you deploy ingress, with Dan Garfield
Ensuring the repeatability of your infrastructure is a crucial aspect of managing Kubernetes clusters.
This allows you to swiftly tear down and set up a new one, a practice that is quite handy.
However, there are exceptional circumstances when your cluster becomes more than a disposable tool.
Dan shared, "A Kubernetes cluster will be treated as disposable until you deploy ingress, and then it becomes a pet...
episode 9: eBPF, sidecars, and the future of the service mesh, with William Morgan
Service meshes and the community's opinion of them have changed drastically over the years.
From being perceived as unnecessary, complicated and bloated, they matured into security and observability powerhouses (while still retaining much of their complexity).
In this KubeFM episode, William deep dives into the world of service meshes and explains a few of the technical choices and trade-offs of service meshes in simple terms...
episode 8: Moving cloud operations to a Kubernetes operator, with Steven Sklar
Can you run databases on Kubernetes and survive to tell the story?
Or should you refrain from running stateful workloads as much as possible?
In this KubeFM episode, Steven argues that you should run databases on Kubernetes.
He also goes further and demonstrates how to build your custom operator to manage your database.
Listen to the episode and learn how:
You can use Kubebuilder and the Operator Framework to build your operator...
episode 7: How Structured Authentication Config changes Kubernetes auth, with Maksim Nabokikh
Structured Authentication Config is the most significant Kubernetes authentication system update in the last six years.
In this KubeFM episode, Maksim explains how this is going to affect you:
You can use multiple authentication providers simultaneously (e.g., Okta, Keycloak, GitLab) — no need for Dex.
You can change the configuration dynamically without restarting the API server...
episode 6: Surviving multi-tenancy in Kubernetes: lessons learned, with Artem Lajko
Is sharing a cluster with multiple tenants worth it?
Should you share or have a single dedicated cluster per team?
In this KubeFM episode, Artem revisits his journey into Kubernetes multi-tenancy and discusses how the landscapes (and opinions) on multi-tenancy have changed over the years.
Here's what you will learn:
The trade-offs of multi-tenancy and the tooling necessary to make it happen (e.g. vCluster, Argo CD, Kamaji, etc.)...
episode 5: Troubleshooting a validation webhook all the way down to the kernel, with Alex Movergan
How hard could it be to debug a network issue where pod connections time out?
It could take weeks if you are (un)fortunate like Alex.
But Alex and his team didn't despair and found strength in adversity while learning several Kubernetes networking and kubespray lessons.
In this KubeFM episode, you'll follow their journey and learn:
How a simple connection refused led to debugging the kernel syscalls...
episode 4: Pod topology spread constraints might not be the best solution, with Martin Humlund Clausen
Pod Topology Spread Constraints is a convenient feature to control how pods are spread across your cluster among failure domains such as regions, zones, nodes, etc.
You can also choose the pod distribution (skew), what happens when the constraint is unfulfillable (schedule anyway vs don't) and the interaction with pod affinity and taints...
episode 3: Transparently providing ARM nodes to 4000 engineers, with Thibault Jamet and Miguel Bernabeu Diaz
On average, Kubernetes nodes running on ARM instances are 20% cheaper than their AMD counterpart.
Optimising your cloud bill is tempting, but how do you seamlessly migrate existing workloads to a different architecture?
And how do you do it at scale, with more than 1500 engineers and 30 clusters in 4 regions?
In this episode of KubeFM, Thibault and Miguel explain how Adevinta built an internal platform on Kubernetes for mixed AMD and ARM workloads...
