guestbook-ts

A simple Kubernetes example

To run this example:

$ npm install

# Transpile typescript to javascript
$ npx tsc

# Run jk on the resulting javascript
$ jk run -v guestbook.js
wrote redis-master-deployment.yaml

redis-master-deployment.yaml should have been produced:

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: redis
  name: redis-master
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
      role: master
      tier: backend
  template:

        role: master
        tier: backend
    spec:

      - image: redis
        name: master
        ports:

Visual Studio Code support

Visual Studio Code supports typescript natively. @jkcfg/kubernetes provides types for Kubernetes objects, allowing type-aware autocompletion and field validation. For example this is vscode showing autocompletion for the PodSpec object.
