1、創建mysql配置文件（nfs存儲）
# mkdir mysql
# cd mysql/
# cat mysql-claim.yaml
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: mysql-claim
annotations:
volume.beta.kubernetes.io/storage-class: "managed-nfs-storage"
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: "10Gi"
2、創建mysql密碼（secret）
# cat mysql-dev-secret.yaml
apiVersion: v1
kind: Secret
metadata:
name: mysql-dev-secret
type: Opaque
data:
MYSQL_ROOT_PASSWORD: cGFzc3dvcmQ=
---
apiVersion: v1
kind: ConfigMap
metadata:
name: mysql-config
data:
my.cnf: |
[mysqld]
pid-file=/var/run/mysqld/mysqld.pid
socket=/var/run/mysqld/mysqld.sock
datadir=/var/lib/mysql
symbolic-links=0
default_storage_engine=innodb
skip_external_locking
skip_host_cache
skip_name_resolve
default_authentication_plugin=mysql_native_password
註明：
#Secret有三種類型：
#Opaque：base64編碼格式的Secret，用來存儲密碼、密鑰等；但數據也通過base64 –decode解碼得到原始數據，所有加密性很弱。
# echo -n cGFzc3dvcmQ= |base64 --decode #通過 base64 將 Value 反編碼
password
3、創建mysql service文件
# cat mysql-svc.yaml
apiVersion: v1
kind: Service
metadata:
name: mysql
spec:
selector:
k8s-app: mysql
ports:
- nodePort: 30306
protocol: TCP
port: 3306
targetPort: 3306
type: NodePort
4、創建mysql 部署文件
# cat mysql-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: mysql
namespace: default
labels:
k8s-app: mysql
spec:
replicas: 1
selector:
matchLabels:
k8s-app: mysql
template:
metadata:
labels:
k8s-app: mysql
spec:
containers:
- image: mysql:5.7.28
name: mysql
imagePullPolicy: Always
envFrom:
- secretRef:
name: mysql-dev-secret #調用密碼文件
ports:
- containerPort: 3306
name: mysql
volumeMounts:
- name: nfs-pv
mountPath: /var/lib/mysql
volumes: # 配置pv
- name: mysql-config #調用config文件
configMap:
name: mysql-config
- name: timezone
hostPath:
path: /usr/share/zoneinfo/Asia/Shanghai
- name: nfs-pv
persistentVolumeClaim:
claimName: mysql-claim #調用存儲文件
5.使用kubectl命令及以上yaml文件部署mysql
# kubectl apply -f ./
# kubectl get pods
# kubectl exec -it mysql-6c6857b4d4-8h9kz bash
# mysql -uroot -p'password'
