Small project SpringBoot/Angular just for testing purpose

Goal

Deploy this small project into a Kubernetes cluster

Technologies ?

Choose what you want as long as you can go quickly (nodejs, java, golang, whatever)

Features expected

Backend

Your app need the following features for the rest of our workshop:

• can read a configuration where we can set up the following parameter: the welcome message content, application name and the version. WARNING: those parameters should be able to read from a file and/or from environment variables.
• can get the host where the app is deployed
• expose those REST endpoints:
  1. /info: a message with a payload containing the host name alongside with the version (aka: vDev running on localhost)
  2. /welcome: a message with a payload containing the welcome message content (ex: Hello world!) Optional:
  3. /whoami: a message with a payload containing only the host name (ex: localhost)
  4. /build: a message with a payload containing only the version (ex: vDev)

Frontend

Your app need the following features for the rest of our workshop:

• read a configuration file where we can set up

  1. application version,
  2. api rest endpoint,
  3. environment name
  4. featre flip a polling to our backend rest endpoint /info.

• a webpage displaying the main content:

  1. welcome message from our backend (/welcome)
  2. backend information (/info). When polling disabled, only display once /info otherwise display every 5s /info

How

1. Create backend and frontend
2. Create docker image for backend and frontend
3. Push to a docker registry
4. Write kubernetes descriptor for backend and frontend
5. Apply descriptors

Correction

You can use this repository code from step 1 to step 7 (use tags 😉)
