一、zookeeper集群实例
1.k8s二进制安装和harbor安装参考文档： https://www.cnblogs.com/Yuanbangchen/p/17219073.html
2.下载JDK镜像，上传镜像到harbor.zzhz.com服务器,此镜像系统为：Alpine
[root@localhost7C zookeeper]# docker pull elevy/slim_java:8
[root@localhost7C zookeeper]# docker tag 0776147f4957 harbor.zzhz.com/pub-images/slim_java:8
[root@localhost7C zookeeper]# docker push harbor.zzhz.com/pub-images/slim_java:8

[root@localhost7B ]# cat /etc/exports
/data/k8sdata *(rw,no_root_squash)
[root@localhost7B ]# mkdir /data/k8sdata/magedu/zookeeper-datadir-1 -p
[root@localhost7B ]# mkdir /data/k8sdata/magedu/zookeeper-datadir-2 -p
[root@localhost7B ]# mkdir /data/k8sdata/magedu/zookeeper-datadir-3 -p
[root@localhost7B ]# systemctl restart nfs-server.service
#写数据测试
mount -t nfs 192.168.80.110:/data/k8sdata/magedu/zookeeper-datadir-1 /mnt
cp /etc/passwd /mnt
umount /mnt/

第一部分基本cnetos系统的另一种写法。
cnetos系统方式创建dockerfile镜像文件
root@master1:/dockerfile/project/zookeeper# cat Dockerfile

ENV ZK_VERSION 3.5.10

ENTRYPOINT [ "/entrypoint.sh" ]
CMD [ "zkServer.sh", "start-foreground" ]
EXPOSE 2181 2888 3888 9010
----------------------------------------
创建zookeeper生成集群配置文件脚本
root@master1:/dockerfile/project/zookeeper# cat entrypoint.sh
#!/bin/bash
echo ${MYID:-0} > /usr/local/zookeeper/data/myid
#k8s zookeeper集群service名称
