Running your build server on Azure(continued)

I talked about running your build server on Azure before. Although this solution worked, it was a cumbersome and time consuming process. You had to install, manage, patch, etc the build machines yourself.

Last week at VS Live, Brian Harry announced and demonstrated a better solution: a new cloud based build service for Team Foundation Service on Azure. With this new service, you can just use a pool of build machines that are manage in the cloud (though you can still install and manage build machines if you like). And, of course, you can do more than just build – like with on-premises TFS, you can run a default workflow that includes, compilation, testing, etc or you can create a custom workflow that does whatever you like.

The new build service works by maintaining a pool of Azure VM roles that can expand and shrink as needed. When you start a build, a VM is allocated from the pool to run your build. Your build is run, the build output is copied off the build machine then the VM is restored and it is returned back to the pool for someone else to use.

This new build service should be enabled for all new and existing accounts on Team Foundation Service.

You can create a new build definition, queue a build, etc the same way you would if you managed the infrastructure. The one difference is that you need to pick the “Hosted Build Controller” in your build definition rather than a local build controller. And (because we don’t have UNC shares in the cloud), you configure the build output (Drop folder) to be a path in version control.

To make it work inside Visual Studio 2010, you have to install the following patch: http://www.microsoft.com/download/en/details.aspx?id=29082

Remark: While I was typing this blog post, the hosted build controller looked to be offline. So it seems there are still some issues(but of course it’s pre-release software).

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
