RBAC (Role Based Access Control) is enabled by default when you deploy a new Azure Kubernetes Service cluster, which is great. But if you are not use to that, you may have some trouble to access the Kubernetes dashboard using kubectl proxy or az aks browse command line tools (remember to never expose the dashboard over the Internet, even if RBAC is enabled!).
In this post, I will explain how you can simply configure RBAC on your cluster to solve authorization access issues.

I recently worked with a customer on hosting Python Flask web app and web jobs on Azure App Service. When it comes to monitoring, Azure Application Insights is really awesome because it allows to collect traces, requests and exceptions very easily and build analytics queries and dashboard for visualization out of the box.
Azure Application Insights comes with a Python SDK that supports direct integration with the Flask Framework. To help you to get started quickly, I have made this quick start sample available on GitHub.
The most important parts of this sample are described below.
Thanks to my colleague Clemens for the precious help.

Azure Container Service (AKS) is a new service (currently in preview) that allows to deploy a managed Kubernetes cluster into Azure. Basically, you only have to pay for the nodes (virtual machines) that run in your cluster and you do not have to deal with Kubernetes masters. Actually, you do not even see Kubernetes masters that are totally managed by the AKS service.
Azure Container Instance (ACI) is a serverless service that allows to spin up both Linux and Windows Containers, without having to deal with complex infrastructure or orchestration system. Machines that run your containers are not visible and you do not pay for them. You only pay for your containers, on a per-minute billing base.
In this blog post I will explain how it is possible to use the ACI-Connector for Kubernetes, that allows to ask Kubernetes to schedule workloads into Azure Container Instance.

Continuous deployment is essential in every software development project as it allows the applications being developed to reach the users as fast as possible, with the best quality as possible.
By automating all the steps that allow your applications to be automatically built, packaged, tested and deployed into several environments, you will drastically reduce the risk of having bugs reaching the end users.
In this article, I will explain how you can use tools like Jenkins and Helm to set up a continuous delivery pipeline of a containerized application that runs on Kubernetes.

When I discuss about Azure Container Service with customers, one of the most frequent question that they ask to me is “is it possible to deploy a cluster into an existing virtual network?”.
And since a few weeks, since the ACS Engine has been released and open sourced on GitHub, I am really happy to be able to answer “yes, and it is really easy!”.
