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!

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...
