When I’m playing with Kubernetes, I usually get a cluster from Google Kubernetes Engine (GKE) because it’s literally a single gcloud command to get a Kubernetes cluster up and running on GKE. It is sometimes useful though to have a Kubernetes cluster running locally for testing and debugging. Minikube is perfect for this.

Minikube runs a single-node Kubernetes cluster inside a VM on your laptop. There are instructions on how to install it on Linux, Mac and Windows. Unfortunately, instructions for Windows is a little lacking, so I want to document how I got Minikube up and running on my Windows 10 machine.

I don’t get to visit this many new places in this short amount of time usually but last week I got to visit 4 cities in 4 countries. The amazing thing was that I had never been to any of these cities or countries before!

My journey started in Copenhagen, Denmark on Monday. I had been in all countries around Denmark but not in Denmark itself, so I was happy to finally add Denmark to the list of visited countries. I had to work on Monday, so I paid a visit the Google office in Copenhagen. This was my the 27th Google office I ever visited 🙂

October 10 was Ada Lovelace Day, a special day to celebrate women in science, technology, engineering and maths. Unfortunately, there are not enough women in software engineering and technology in general. Programs like Women Techmakers do a good job to encourage more women participation in technology with meetups, conferences and hackathons. One of those conferences, Tech(k)now Day, happened in London on Ada Lovelace Day and I was happy that Google Cloud was a sponsor. We had a booth and I was there with other Googlers answering questions. I also gave a talk on Containers and Kubernetes to a small group of 30+ people.

In my previous post, I talked about how to deploy a containerised ASP.NET Core app to App Engine (flex) on Google Cloud. App Engine (flex) is an easy way to run containers in production: Just send your container and let Google Cloud figure out how to run it at scale. It comes with some nice default features such as versioning, traffic splitting, dashboards and autoscaling. However, it doesn’t give you much control.

I love how easy it is to deploy and run containerized ASP.NET Core apps on App Engine (flex). So much so that, I created a Cloud Minute recently to show you how, here it is.

It basically involves 3 steps:

1. Create your ASP.NET Core app using dotnet command line tool inside Cloud Shell and publish your app to get a self-contained DLL.
2. Containerize your app by creating a Dockerfile, relying on the official App Engine image and pointing to the self-contained DLL of your app.
3. Create an app.yaml file for App Engine and use gcloud to deploy to App Engine.

That’s it! If you want to go through these steps yourself, we also have a codelab for you that you can access here.

gRPC is an RPC framework developed and open-sourced by Google. There are many benefits to gRPC, such as efficient connectivity with HTTP/2, efficient data serialization with Protobuf, bi-directional streaming and more, but one of the biggest benefits is often overlooked: multi-language support.

Out of the box, gRPC supports multiple programming languages : C#, Java, Go, Node.js, Python, PHP, Ruby and more. In the new microservices world, the multi-language support provides the flexibility you need to implement services in whatever language and framework you like and let gRPC handle the low-level connectivity and data transfer between microservices in an efficient and consistent way.

Introduction

Until recently, there were two distinct camps in the software world: the Windows (A.K.A. closed) world and the Linux (A.K.A. open) world. In the Linux world, we had tools like the bash shell, Java programming language, Eclipse IDE, MySQL database, and many other open-source projects by Apache. In the Windows world, we had similar, yet distinct tools mainly developed by Microsoft, such as the C# programming language, Visual Studio IDE, SQL Server and PowerShell.

Google Developers Codelabs provide guided coding exercises to get hands-on experience with a wide range of topics such as Android Wear, Firebase and Web. Google Cloud Platform (GCP) has its own section, with codelabs for Google Compute Engine, Google App Engine, Kubernetes and many more.

We’re always working to create new content, and I’m happy to announce that we now have new codelabs for running Windows and .NET apps on GCP, with their own dedicated page. Here’s an overview to help you get started.

I remember the old days where we used to package all our modules into a single app (aka the Monolith), deployed everything all at once and called it an enterprise app. I have to admit, the first time I heard the term enterprise app, it felt special. Suddenly, my little module was not so little anymore. It was part of something bigger and more important, at least that’s what I thought. There was a lot of convention and overhead that came with working in this enterprise app model but it was a small price to pay for consistency, right?

In my previous post, I promised to talk about some good conferences I’m attending or speaking over the coming months. One of those conferences that I’m most excited about is Google Cloud Next’17: Google’s main cloud conference happening March 8–10 in San Francisco.

Last year, I attended that conference as a Noogler. There were a lot of developers and great technical content. This year’s schedule has just been published and it looks even more exciting, especially if you’re a .NET developer!
