Creating a Kubernetes cluster using Kops requires a top-level domain or a sub domain and setting up Route 53 hosted zones. This domain allows the worker nodes to discover the master and the master to discover all the etcd servers. This is also needed for kubectl to be able to talk directly with the master. This worked well but an additional hassle for the developers. Kops ...

Service Virtualization is a technique using to emulate the behaviour of dependencies of component-based applications.

It is a proxy which responds to HTTP(S) requests with stored responses, pretending to be it’s real counterpart. Hoverfly Java is a wrapper around Hoverfly, that let’s you use it ...

In my previous post, I looked at parsing command-line arguments in Java applications using Apache Commons CLI. In this post, I look at doing the same using a different library: args4j. args4j takes a different approach to specifying which command-line arguments the Java application should expect than that used by Commons CLI. While Commons CLI expects objects representing the options ...
