Installing Ruby Gems when sitting behind the firewall

For a customer project, I had to use some Ruby tools. To include some external libraries I opened up gem, the package manager of Ruby.

So I opened a command prompt and triggered the installation of the package I needed:

gem install ‘svn2git’

But no matter what I tried, it always failed with the following error message:

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    too many connection resets (http://rubygems.org/latest_specs.4.8.gz)

I figured out that it was caused by the proxy script that was used on the customer’s pc I was using. As the environment was well secured, I couldn’t do anything to bypass the proxy.

Luckily there is a workaround(isn’t there always one? Knipogende emoticon)

  • Search for the gem that you are interested in.
  • On the gem page, you’ll find  a download button. Click it to download the gem directly and save it to the directory of your choice.

  • To install the downloaded gem, browse to the location where you saved it and execute the following command:

gem install svn2git-2.2.2.gem

  • That’s it!

.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...
