A Crash Course For Running Istio (medium.com)
Published: Wednesday, 05 June 2019.
At Namely we’ve been running with Istio for a year now. Yes, that’s pretty much when it first came out. We had a major performance regression with a Kubernetes cluster, we wanted distributed tracing, and used Istio to bootstrap Jaeger to investigate. We immediately saw the potential of a service mesh as it relates to our infrastructure and decided to make an investment in the tool.

Configure Helm TLS communication with multiple Kubernetes clusters (medium.com)
Published: Friday, 16 November 2018.  By:Maor Friedman
So, finally decided to secure your Helm installation? That`s great! Sounds easy enough, right? And as an extra, all sources seem to be telling the exact same story: “All you have to do is follow these steps, and you are good to go”. Right? Wrong. Well, not really wrong, it is a fairly simple procedure, but brace yourself for more typing. Much more. A bit more. There you are. But have no fear, the solution is here (in this post, if that was unclear).

According to the docs, in Kubernetes, ConfigMap resources “allow you to decouple configuration artifacts from image content to keep containerized applications portable.” Used with Kubernetes pods, configmaps can be used to dynamically add or change files used by containers.

Istio Routing Basics (medium.com)
Published: Friday, 02 November 2018.  By:Mete Atamel, Developer Advocate at Google
When learning a new technology like Istio, it’s always a good idea to take a look at sample apps. Istio repo has a few sample apps but they fall short in various ways. BookInfo is covered in the docs and it is a good first step. However, it is too verbose with too many services for me and the docs seem to focus on managing the BookInfo app, rather than building it from ground up. There’s a smaller helloworld sample but it’s more about autoscaling than anything else.
