Azure Kubernetes容器环境变量

Question

so in Docker, I can do a Docker run -e to pass in environment variables.

But how does one do that for Azure Kubernetes Pods? They aren't username/password kinds of variables but more so URLs segments we would want to use during startup.

http://webapi/august where august is what we would want to pass in, then in September, we would want to pass in september .

This aren't the best examples, but it shows what I'm looking for.

Thanks.

There is a clear example on kubernetes documentation for this - https://kubernetes.io/docs/tasks/inject-data-application/define-environment-variable-container/

Short example from there:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.7.9
        ports:
        - containerPort: 80
        env:
        - name: DEMO_GREETING
          value: "Hello from the environment"
        - name: DEMO_FAREWELL
          value: "Such a sweet sorrow"

Take a note of env

later if you want to change the variable on the fly - you can use kubectl set env -h command
