In the last two posts, I covered the native storage options on Azure Kubernetes Service, as well as Portworx as an example of a proprietary Software Defined Storage (SDS) solution. There are also a number of open-source alternative SDS solutions. Ceph has nearly a decade of history from prior to containerization, and is the most … Read moreKubernetes Storage on Azure 3 of 3 – Ceph by Rook
In the previous post, we have discussed built-in storage classes on Azure Kubernetes. Further to that, we will examine some third-party software defined storage (SDS) options that are compatible with Azure Kubernetes Service in this post. Then we take Portworx on Azure as an example. Although, these options are specific to Azure, most of the … Read moreKubernetes Storage on Azure 2 of 3 – Portworx
In the previous post, we understand that to host stateful workload, we need to manage persistent storage to the Kubernetes platform. In this post, I will explore the different storage options. These options are specific to Azure Kubernetes service. However, the principals apply to any Kubernetes platform regardless of cloud vendor. In another old post, … Read moreKubernetes Storage on Azure 1 of 3 – built-in storage and NFS
This post discusses admission control, and its implementation – the OPA Gatekeeper. I also discuss Azure Policy as a different Gatekeeper implementation. Admission Webhooks Admission controller intercepts requests to the Kubernetes API server after the request has been authenticated and authorized, and prior to persistence of the object into etcd store. There are many compiled-in … Read moreKubernetes Admission Control

In general, troubleshooting Kubernetes is tricky. That is because one has to get in and out of pods. I took two days to troubleshoot some networking issues with private AKS cluster. For the amount of of tricks I had to employ, I need to take some notes. The issue After writing the Terraform code, I … Read moreAKS Lessons Learned 1 of 2
