Raspberry Pi ESXi ARM Edition – Photon OS 4.0 & Kubernetes Cluster (K3s)

Freitag, Februar 26th, 2021

Kubernetes is a 10-letter word stylized as K8s so something half as big as Kubernetes would be a 5-letter word stylized as K3s – is a highly available certified Kubernetes distribution designed for production workloads in unattended resource-constrained remote locations or inside IoT appliances and it is packaged as a single <40MB binary that reduces the dependencies and steps needed to install run and auto-update a production Kubernetes cluster

   Photon OS – is a Linux based open source security-hardened enterprise grade appliance operating system that is purpose built for Cloud and Edge applications

VMware vSphere CSI 2.0 – with native Kubernetes to encrypt individual Persistent Volumes on vSAN

Sonntag, Juli 26th, 2020

VMware vSphere CSI 2.0 – to create a Storage Policy Based Management (SPBM) with the VM Encryption feature which can be used with vSphere CSI/CNS to create a Kubernetes Storage Class that encrypts Persistent Volumes. This feature is only available with the CSI 2.0 driver for native, upstream Kubernetes deployed on vSphere 7.0 (at the time of writing). You will also need to have a Key Management Server available to the vSphere host to create a policy that allows encryption. Finally, encrypted Persistent Volumes can only be attached to encrypted virtual machines, meaning that at least one of your Kubernetes worker nodes, deployed as a VM on vSphere, will need to be encrypted

VMware vSphere 7 – this is not just a little UI update we’ve done here we’ve fundamentally built Kubernetes into our software-defined data center
