拉取zookeeper镜像

语法：docker pull zookeeper
这是拉取的最新版本的官方镜像，也可以选择其它版本的镜像
示例：

[root@izbp13xko46hud9vfr5s94z /]# docker pull zookeeper 
Using default tag: latest
latest: Pulling from library/zookeeper

Status: Downloaded newer image for zookeeper:latest
[root@izbp13xko46hud9vfr5s94z /]#

启动zookeeper容器实例

语法：docker run --name zookeeper --restart always -d zookeeper
--restart always：始终重新启动zookeeper
示例：

[root@izbp13xko46hud9vfr5s94z /]# docker run --name zookeeper --restart always -d zookeeper

[root@izbp13xko46hud9vfr5s94z /]#

查看当前zookeeper容器实例的进程信息

语法：docker top zookeeper
zookeeper：表示当前zookeeper实例的名称，通过--name指定，也可以使用容器ID来替代
示例：

docker top zookeeper
UID                 PID                 PPID                C                   STIME               TTY                 TIME                CMD

[root@izbp13xko46hud9vfr5s94z /]#

也可以通过ps -ef | grep zookeeper来查看进程信息，示例如下：

[root@izbp13xko46hud9vfr5s94z /]# ps -ef | grep zookeeper

[root@izbp13xko46hud9vfr5s94z /]#

停止zookeeper实例进程

语法：docker stop zookeeper
示例：

[root@izbp13xko46hud9vfr5s94z /]# docker stop zookeeper 
zookeeper
[root@izbp13xko46hud9vfr5s94z /]#

启动、重启zookeeper实例进程

启动语法：docker start zookeeper
重启语法：docker restart zookeeper
示例：

[root@izbp13xko46hud9vfr5s94z /]# docker start zookeeper
zookeeper
[root@izbp13xko46hud9vfr5s94z /]# docker restart zookeeper 
zookeeper
[root@izbp13xko46hud9vfr5s94z /]#

查看zookeeper进程日志

语法：docker logs -f zookeeper
示例：

[root@izbp13xko46hud9vfr5s94z /]# docker logs -f zookeeper

语法：docker run -it --rm --link zookeeper:zookeeper zookeeper zkCli.sh -server zookeeper
说明：-server zookeeper是启动zkCli.sh的参数

杀死zookeeper实例进程

语法：docker kill -s KILL zookeeper
示例：

[root@izbp13xko46hud9vfr5s94z /]# docker kill -s KILL zookeeper 
zookeeper
[root@izbp13xko46hud9vfr5s94z /]#

移除zookeeper实例

语法：docker rm -f -v zookeeper
示例：

[root@izbp13xko46hud9vfr5s94z /]# docker rm -f -v zookeeper 
zookeeper
[root@izbp13xko46hud9vfr5s94z /]#

集群方式安装

集群方式选择使用docker-compose来完成。
编写配置文件，并将其命名为：docker-compose.yml（docker-compose默认配置文件名）
配置文件内容：

version: '2'
services:
    zoo1:
        image: zookeeper
        restart: always
        container_name: zoo1
        ports:
            - "2181:2181"
        environment:
            ZOO_MY_ID: 1
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

    zoo2:
        image: zookeeper
        restart: always
        container_name: zoo2
        ports:
            - "2182:2181"
        environment:
            ZOO_MY_ID: 2
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

    zoo3:
        image: zookeeper
        restart: always
        container_name: zoo3
        ports:
            - "2183:2181"
        environment:
            ZOO_MY_ID: 3
            ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

此配置文件表示，Docker需要启动三个zookeeper实例，并将2181，2182，2183三个端口号映射到容器内的2181这个端口上。
ZOO_MY_ID：表示zk服务的ID, 取值为1-255之间的整数，且必须唯一
ZOO_SERVERS：表示zk集群的主机列表

启动zookeeper集群

语法：docker-compose up -d
该命令执行需要在docker-compose配置文件的目录下执行。
示例：

[root@izbp13xko46hud9vfr5s94z conf]# pwd 
/develop/conf
[root@izbp13xko46hud9vfr5s94z conf]# ls 
docker-compose-zookeeper.yml
[root@izbp13xko46hud9vfr5s94z conf]# COMPOSE_PROJECT_NAME=zookeeper_cluster docker-compose up
-bash: docker-compose: 未找到命令
[root@izbp13xko46hud9vfr5s94z conf]#

本例在执行过程中，遇到了-bash: docker-compose: 未找到命令的错误，解决方案是下载docker-compose并安装即可。
安装命令：

curl -L https://github.com/docker/compose/releases/download/1.22.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

安装完成后，重新执行docker-compose up -d这个命令，结果如下：

[root@izbp13xko46hud9vfr5s94z conf]# docker-compose up -d 
Starting zoo1 ... done
Starting zoo2 ... done
Starting zoo3 ... done
[root@izbp13xko46hud9vfr5s94z conf]#

查看zookeeper集群实例

通过docker ps查看

[root@izbp13xko46hud9vfr5s94z ~]# docker ps 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                                        NAMES

[root@izbp13xko46hud9vfr5s94z ~]#

通过docker-compose ps查看
这个命令需要在docker-compose配置文件下执行。

[root@izbp13xko46hud9vfr5s94z conf]# docker-compose ps 
Name              Command               State                     Ports                   
------------------------------------------------------------------------------------------
zoo1   /docker-entrypoint.sh zkSe ...   Up      0.0.0.0:2181->2181/tcp, 2888/tcp, 3888/tcp
zoo2   /docker-entrypoint.sh zkSe ...   Up      0.0.0.0:2182->2181/tcp, 2888/tcp, 3888/tcp
zoo3   /docker-entrypoint.sh zkSe ...   Up      0.0.0.0:2183->2181/tcp, 2888/tcp, 3888/tcp
[root@izbp13xko46hud9vfr5s94z conf]#

停止、启动、重启docker-compose服务

示例：

[root@izbp13xko46hud9vfr5s94z conf]# docker-compose stop
Stopping zoo1 ... done
Stopping zoo2 ... done
Stopping zoo3 ... done
[root@izbp13xko46hud9vfr5s94z conf]# docker-compose start 
Starting zoo1 ... done
Starting zoo2 ... done
Starting zoo3 ... done
[root@izbp13xko46hud9vfr5s94z conf]# docker-compose restart
Restarting zoo1 ... done
Restarting zoo2 ... done
Restarting zoo3 ... done
[root@izbp13xko46hud9vfr5s94z conf]#

如何查看zookeeper集群节点主从关系

使用docker exec -it zoo1 /bin/bash这个命令进入zoo1节点中，之后输入./bin/zkServer.sh statu来查看节点主从关系
示例：

[root@izbp13xko46hud9vfr5s94z conf]# docker exec -it zoo1 /bin/bash 
bash-4.4# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
Mode: follower
bash-4.4#
