Docker安装Zookeeper

1、拉取 Zookeeper 镜像：

[root@localhost ~]# docker pull zookeeper
Using default tag: latest
Trying to pull repository docker.io/library/zookeeper ... 
latest: Pulling from docker.io/library/zookeeper

Status: Downloaded newer image for docker.io/zookeeper:latest

2、创建并运行一个容器：

[root@localhost ~]# docker run --name myZookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 --restart always -d zookeeper

Zookeeper 默认暴露 2181、2888、3888 这三个端口，分别为客户端端口，集群端口，选举端口。
