Setting Effective CPU and Memory Limits for your K8s Apps
Deploying a microservice on K8s is easy; keeping a microservice running is another story. Without your help, Kubernetes cannot know an app’s resource requirements. Unattributed apps are likely to get evicted from one node after another. This talk, from February’s San Francisco Kubernetes Meetup, delves into several techniques for effectively sizing pod resources, keeping apps…
Read MoreInstrumenting Microservices for K8s – How to Make Your Apps Optimally Operational
Microservices need an operational tune-up in order to perform their best on Kubernetes. This talk, given at the San Francisco Kubernetes Meetup in February, dives into the essential additions needed for highly-efficient microservice deployments on Kubernetes. Randy covers liveness probes, readiness probes, open metrics, logging necessities, and traceability, as well as best practices and strategies…
Read MoreHow do you handle special pod startup needs with Init Containers?
Init containers run when a pod is first initialized. Their job is to run bootstrapping tasks before a pod’s primary application container runs. Init containers are great for separating preparation steps from operations. They run in sequence, each one completing their assigned task before the next init container or any application container runs. If any…

Read MoreA Quick Review of Kubernetes etcd
So you’ve got a Kubernetes cluster, now what? etcd is the persistent key-value store that holds the state of a Kubernetes cluster.

Read MoreHow does Kubernetes Ingress work?
In this quick video, we answer the question of how Ingresses in Kubernetes work. Ingresses manage external access to services and pods within a cluster. We start with three pods in our cluster, with their IP addresses ending at .9, .17, and .22. These pods use an existing pod network with the CIDR of 10.32.x./16.…
Read MoreUsing Raw API calls to control Kubernetes
This quick video explains how you configure Kubernetes pods to control Kubernetes itself with raw API calls. Most users interact with Kubernetes using kubectl. kubectl itself is a sophisticated wrapper for “curl” and communicates with a Kubernetes cluster’s API server. Using the -v flag followed by a number tells kubectl to show the exact call…
