Kubernetes multi node cluster with Vagrant (included Kubernetes Dashboards, Grafana, Prometheus)
The following Vagrantfile code(syntax is Ruby) is creating one master node and two worker nodes for Kubernetes.
Go to Vagrantfile directory in Terminal and run the following code to create virtual machines.
The following Vagrantfile code(syntax is Ruby) is creating one master node and two worker nodes for Kubernetes.
Go to Vagrantfile directory in Terminal and run the following code to create virtual machines.

Chain of Responsibility Pattern and Aspect Oriented Programming with C#.NET
Each class contains only the business logic code, while the aspects will be responsible of intercepting the code in order to inject the cross-cutting concerns.
This is first version of example code.
This is second version. You can find MethodInfo and parameter values in the aspect classes.
