kustomize 模版自由的配置&&自定义kubernetes工具

kustomize 是一个可以方便我们基于模版配置，自定义kubernetes 的工具，类似kompose，但是个人觉得kompose
更灵活点，而且使用上更方便

安装

mac

brew install kustomize

基本使用

创建kustomization.yaml 文件（类似docker-compose）

touch kustomization.yaml
内容如下：
   commonLabels:
     app: hello
   resources:
   - deployment.yaml
   - configMap.yaml
   - service.yaml

如下：

resource 定义

deploy:
apiVersion: apps/v1
kind: Deployment
metadata:
  name: appdmeo
spec:
  selector:
    matchLabels:
      app: appdmeo
  template:
    metadata:
      labels:
        app: appdmeo
    spec:
      containers:
      - name: appdmeo
        image: nginx
        ports:
        - containerPort: 80
service:
kind: Service
apiVersion: v1
metadata:

spec:
  selector:
    app: appdmeo

configmap：
apiVersion: v1
kind: ConfigMap
metadata:
  name: myconfigmap
