Kubectl – check all the contexts
Every so ofter I get in a situation where I need to see if my configuration is still valid for every cluster in my Kubernetes config. I blogged a while back about managing multiple configs. Then, eventually, your K8s config ends up looking like this: It gets tedious to go through every config like this: […]

Use Kasten K10 to migrate K8s Volumes to Pure Storage
TL;DR – Move Kubernetes volumes from legacy storage to Pure Storage. So you have an amazing new Pure Storage array in the datacenter or in public cloud. The Container Storage Interface doesn’t provide a built in way to migrate data between backend devices. I previously blogged about a few ways to clone and migrate data […]

Hey, Don’t break EBS
TL;DR – EBS Volumes fail to mount when multipathd is installed on EKS worker nodes. AWS Elastic Kubernetes Service is a great way to dive in with managed Kubernetes in the cloud. Pure Service Orchestrator integrates EKS worker nodes into the Cloud Block Store on AWS. I created this ansible playbook to make sure the […]

As an integral part of Pure’s Kubernetes integration, Pure Service Orchestrator has the ability to load balance across a fleet of Pure storage devices. This is great for your containerized space, but I wondered […]

Upgrading K8s to 1.17.4 and PSO to 5.1.0
This morning I needed to upgrade one of my dev clusters to 1.17.4. I decided to capture the experience. Don’t worry I speed up the ansible output flying by I use Kubespray to deploy and upgrade my clusters. I didn’t do anything really to prepare. All of my clusters I can rebuild pretty easy from […]
