pizza-controller

making kubernetes do what it was always meant to do: order pizza.

usage

First, create a secret with the credit card information (yeah, this is fine, trust me) to be used during payment:

kind: Secret
apiVersion: v1
metadata:
  name: credit-card
stringData:
  number: 123343132314232
  expiration: 12/02
  securityCode: 123
  zip: m5d0l2

then, create a PizzaCustomer, the representation of you, the customer:

kind: PizzaCustomer
apiVersion: ops.tips/v1alpha1
metadata:
  name: you
spec:
  firstName: barack
  lastName: obama
  email: obama@gov.gov
  phone: "31241323"
  streetNumber: "20"
  streetName: King St
  city: Toronto
  state: "ON"
  zip: m5lz8j

With the PizzaCustomer object created, we can see what's the closest store available for it:

$ kubectl get pizzacustomer
NAME              CLOSEST
you               store-123

Looking at the PizzaStore object, we can check out its menu:

$ kubectl get pizzastore store-123 -o yaml
kind: PizzaStore
metadata:
  name: store-123
spec:
  address: |
    51 Niagara St
    Toronto, ON M5V1C3
  id: "10391"
  phone: 416-364-3939
  products:
    - description: Unique Lymon (lemon-lime) flavor, clear, clean and crisp with no caffeine.
      id: 2LSPRITE
      name: Sprite
      size: 2 Litre

Knowing what's available to us, we can place the order:

kind: PizzaOrder
apiVersion: ops.tips/v1
metadata:
  name: ma-pizza
spec:
  yeahSurePlaceThisOrder: true  # otherwise, it'll just calculate the price
  storeRef: {name: store-123}
  customerRef: {name: you}
  payment:
    creditCardSecretRef: {name: cc}
  items:
    - ticker: 10SCREEN
      quantity: 1

To keep track of what's going on with your pizza, check out the order's status:

$ kubectl get pizzaorder ma-pizza
NAME    PRICE      ID                     CONDITION     AGE
order   9.030000   Wlz6HcE6BPlfQNlxDAXa   OrderPlaced   68m

what's next?

are you really into ordering pizza using kubectl?

like, really? are you sure?

here's what's missing:

• well, any .. tests 🐴
• order tracking (it's xml-based - SOAP stuff)
• being more flexible with non-canadian folks (it's currently hardcoded for Canada, but could easily be changed)

at the moment I got my pizza .. development finished 😅 maybe you'll carry it forward?

Installation

1. apply the manifest

git clone https://github.com/cirocosta/pizza-controller
cd pizza-controller

# using `kapp` - recommended :)

#
kubectl apply -f ./config/release.yaml
