Docker containers on Windows & Linux, also micro-services architecture (e.g. Azure Service Fabric).
Let’s look at a concrete problem: I have containers deployed in AKS Those container log into custom files I want to analyse those logs using Azure Monitor (Log Analytics) We’ll look at how to do that. We leverage Azure Monitor for containers. Custom logs in Log Analytics also is interesting. That component allows us to … More Custom Logs on AKS & Azure Monitor
Some workloads running on Azure Kubernetes Service (AKS) requires persisting state on disk. In general, I recommend to use external PaaS services, i.e. Azure Blob Storage, Azure SQL DB, Azure Cosmos DB, etc. . Those services take care of the stateful nature of the service, manages HA, backups, geo-replication, etc. . Persisting state on disks … More Dynamic disks in AKS
In this article I wanted to talk about a book I just finished reading. Although its title and scope is around distributed systems in general, Brendan Burns discussion is mostly using containers & Kubernetes. Brendan Burns is currently (as of this writing in November 2018) at Microsoft. He is a cofounder of the Kubernetes project. … More Designing Distributed Systems by Brendan Burns
Last time, I covered the ins and outs of Ingress on AKS. We looked at how to install nginx ingress controller and how the controller is deployed as a load balanced service. We did some URL based routing and domain name overloading. This was in the spirit of clarifying the magic behind Ingress Controllers. Another … More Understanding multiple Ingress in AKS
We looked at Kubernetes Ingress conceptually. We looked at different use cases: URL based routing and multiple domains. We also looked at how ingress was implemented from an AKS perspective, i.e. where traffic was routed in nodes. In this article, I wanted to get hands on. I figured we could start slowly with simple configuration: … More Understanding simple HTTP Ingress in AKS
In the last article, we authored a very simple chart. In this article I want to show how to use one of the powerful features of Helm: values. Values act as parameters to a chart. Having parameters is key for dev ops as we want to deploy the same chart to different environment with different … More Authoring a Helm Chart on Kubernetes / AKS – Parametrized values
As we discussed in our last article, Helm is a great technology. I recommend using it not only to manage third party packages but also your own custom-developed solutions. But how do you author a Helm Chart? I found that question hard to answer. The common answer is “look at existing ones”. I have two … More Authoring a Helm Chart on Kubernetes / AKS – Getting started
