Question

我正在mac-docker-desktop中使用k8s。我用下面的配置部署一个mysql pod。

运行于：kubectl apply -f mysql.yaml

# secret
apiVersion: v1 
kind: Secret
metadata:
  name: mysql
type: Opaque
data:
  # root
  mysql-root-password: cm9vdAo=

        persistentVolumeClaim:
          claimName: mysql
      containers:
        - image: mysql:5.6
          name: mysql
          env:
            - name: MYSQL_ROOT_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: mysql
                  key: mysql-root-password
            - name: MYSQL_DATABASE
              valueFrom:
                configMapKeyRef:
                  name: mysql-conf
                  key: database
          ports:
            - containerPort: 3306
              name: mysql
          volumeMounts:
            - name: mysql
              mountPath: /var/lib/mysql
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql
  labels:
    app: mysql
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:

# services
apiVersion: v1
kind: Service 
metadata:
  name: mysql
  labels:
    app: mysql
spec:
  selector:
    app: mysql
  ports:
    - port: 3306  
      targetPort: 3306

之后。它显示确定。然后，我想将mysql服务器与节点ip连接，但是失败了。然后我在吊舱中执行，也失败了。

我在广告连播中执行，无法登录。

我的配置文件有问题吗？

Answer 1

可能您的base64编码密码无效。试试这个：

data:
  pass: cm9vdA==

Answer 2

正如@Vasily Angapov指出的那样，您的base64编码是错误的。

执行以下操作时，您正在编码 root \ n

的基础

echo "root" | base64

输出：

cm9vdAo =

如果要删除换行符，则应使用选项 -n ：

echo -n "root" | base64

输出：

cm9vdA ==

执行以下操作甚至更好：

echo -n "root" | base64 -w 0

这样base64不会在更长的输出中插入新行。

您还可以通过解码编码文本来验证编码是否正确：

echo "cm9vdA==" | base64 --decode

输出不应创建新行。
