linux - 如何在 kubernetes 中部署 nginx.config 文件

Question

最近我开始学习 Kubernetes，现在我可以使用默认选项部署 nginx。但是我如何在 Kubernetes 中部署 nginx.conf 呢？也许有人有一个简单的例子？

为 nginx 部署创建 yaml:

kubectl run --image=nginx nginx -o yaml --dry-run

apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    run: nginx
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      run: nginx
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        run: nginx
    spec:
      containers:
      - image: nginx
        name: nginx
        resources: {}
status: {}

创建配置ConfigMap与 nginx 配置

kubectl create configmap nginx-conf --from-file=./nginx.conf

挂载文件:

apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    run: nginx
  name: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      run: nginx
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        run: nginx
    spec:
      containers:
      - image: nginx
        name: nginx
        resources: {}
        volumeMounts:
        - mountPath: /etc/nginx/nginx.conf
          name: nginx-conf
          subPath: nginx.conf
      volumes:
      - configMap:
          name: nginx-conf
        name: nginx-conf
