I-Ching
The I-Ching (a.k.a. the Book of Changes) is an ancient method of divination based on cleromancy (assigning meaning to the generation of apparently random numbers.) Six numbers between 6 and 9 are generated in order to create a hexagram, the meaning of which is contained in the I Ching book.
You can find lots of great information on the 2000+ year history of the I-Ching on Wikipedia
This app will send an I-Ching horoscope to the pre-configured mailhog instance in configurable intervalls.
This app uses the I-Ching library app https://github.com/Velfi/i-ching.git.
First Start
The app can be deployed by running:
$ kubectl apply -f ingress.yaml
$ kubectl apply -f service.yaml
$ kubectl apply -f deployment.yaml
When a pod with the app is initally started, one email will be sent to the configured receiver.
Backend Server
The backend server is running inside the pod on the address http://localhost:8090/command. If a POST is sent to this address, the server will run the main logic of this app: An E-Mail with an I-Ching horoscope (provided by the library app) will be sent to the configured email address.
The backend server can be tested from inside the pod by calling 'curl -X POST http://localhost:8090/command' from the console.
HTTP Server
The frontend server is running inside the pod on the address http://localhost:8080/iching. It provides an HTML homepage with a button. Upon pressing the button, the backend server will be called (to send an E-Mail).
