自定义Chart-不使用”values.yaml”

自定义Chart-不使用"values.yaml"

(1)清空Chart模板，用于自定义

rm -rf baimeilinux/templates/* 

(2)清空values文件

> baimeilinux/values.yaml

(3)自定义Chart信息

cat > baimeilinux/Chart.yaml <<'EOF'
apiVersion: v2
name: baimeilinux
description: baimei linux86 k8s tomcat demo deploy
type: application
version: "v0.1"
appVersion: "1.0"
EOF

(4)创建资源清单

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql
spec:
  replicas: 1
  selector:
    matchExpressions:
    - key: app
      operator: Exists
  template:
    metadata:
      labels:
        app: baimei-mysql
    spec:
      volumes:
       - name: data
         nfs:
           server: master231
           path: /baimei/data/kubernetes/tomcat-db
      containers:
        - name: mysql
          image: harbor.baimei.com/baimei-db/mysql:5.7
          ports:
          - containerPort: 3306
          env:
          - name: MYSQL_ROOT_PASSWORD
            value: '123456'
          volumeMounts:
          - name: data
            mountPath: /var/lib/mysql
