默认已经安装好k8s环境

环境检查

# kubectl get pod  --all-namespaces
NAMESPACE         NAME                                    READY   STATUS    RESTARTS   AGE

kube-system       coredns-f9fd979d6-sb4pf                 1/1     Running   0          23h

kube-system       kube-proxy-xcqvm                        1/1     Running   0          23h
kube-system       kube-scheduler-langll-ubuntu            1/1     Running   1          23h

确定 k8s都已经启动正常

创建yaml文件

打开vim 编辑文件，

# 可以在任意目录下执行
# vim oracle.yaml

复制下面内容到 oracle.yaml中

apiVersion: v1
kind: Namespace
metadata:
  name: oracle-server
---
apiVersion: v1
kind: Service
metadata:
 name: oracle-server
 namespace: oracle-server

        ports:

        command: ['/assets/entrypoint.sh']
        env:

          value: "/opt/oracle/app/product/11.2.0/dbhome_1"
        - name: ORACLE_SID
          value: "orcl"
        volumeMounts:  #挂载持久存储卷 
        - name: oracle-volume #挂载设备的名字，与volumes[*].name 需要对应     
          mountPath: /opt/oracle/dpdump/1/dump_dir #挂载到容器的某个路径下   
          readOnly: true
      volumes: #定义一组挂载设备   
      - name: oracle-volume #定义一个挂载设备的名字   
        hostPath:   
          path: /home/langll/Documents/docker/volumes/oracle/dump_dir #挂载设备类型为hostPath，路径为宿主机下的/opt,这里设备类型支持很多种 

保存并退出

执行安装

# 需要在oracle.yaml同目录下执行
# kubectl apply -f oracle.yaml

查看启动结果

查看结果最好等待10-20分钟，因为oracle的安装过程在容器内部有多次重启。

# kubectl get pod  --all-namespaces
