1、下载镜像

docker pull zookeeper

2、创建ZooKeeper 挂载目录（数据挂载目录、配置挂载目录和日志挂载目录）

数据挂载目录

mkdir -p /usr/local/zookeeper/data 

配置挂载目录

mkdir -p /usr/local/zookeeper/conf

日志挂载目录

mkdir -p /usr/local/zookeeper/logs

3、添加ZooKeeper配置文件

在挂载配置文件目录(/user/local/zookeeper/conf)下，新增zoo.cfg 配置文件，配置内容如下

# The number of  milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
 
## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true

4、启动ZooKeeper容器

docker run -d \
--name zookeeper \
--privileged=true \
-p 2181:2181 \
--restart=always \
-v /usr/local/zookeeper/data:/data \
-v /usr/local/zookeeper/conf:/conf \
-v /usr/local/zookeeper/logs:/datalog \
zookeeper

5、测试连接
