Use docker to make a zookeeper image

Install docker and set up the environment

yum install -y docker

systemctl enable docker

service docker start

A management interface for docker

docker run -d -p 9000:9000 --privileged -v /var/run/docker.sock:/var/run/docker.sock uifd/ui-for-docker

Set up Dockerfile

#The command to execute when starting the container
#Container entry, turn the zookeeper container into a zookeeper server
#docker run -p 2181:2181 --name docker-zookeeper xiaofancn/zookeeper print-cmd
ENTRYPOINT ["/root/zookeeper-3.4.11/bin/zkServer.sh"]
#Running in the foreground, if this is not set, if zookeeper runs in the background, the container will automatically close and enter the Exited state
#Parameters followed when the container starts = docker run -p 2181:2181 --name docker-zookeeper xiaofancn/zookeeper start-foreground
#Append parameters such as print-cmd when starting, which will override the default parameters
#start-foreground output logs, the output of logs is kept in the container, and the docker keeps the up state.
CMD ["start-foreground"]

#exposed ports
EXPOSE 2181 2888 3888

build image

docker build -t="xiaofancn/zookeeper" .

Clean up before startup

docker stop docker-zookeeper && docker rm docker-zookeeper

docker run -d -p 2181:2181 --name docker-zookeeper xiaofancn/zookeeper

docker inspect docker-zookeeper

zk for linked container

./zookeeper-3.4.11//bin/zkCli.sh -server localhost:2181

Create a new set of subnets

docker network create --subnet=172.18.0.0/16 shadownet

Bind ip to start zk

docker run --network=shadownet --ip=172.18.0.10 -d -p 2181:2181 --name docker-zookeeper_1 xiaofancn/zookeeper

docker run --network=shadownet --ip=172.18.0.11 -d -p 2182:2181 --name docker-zookeeper_2 xiaofancn/zookeeper

开两个控制台分别执行

docker run -it --network=shadownet --ip=172.18.0.12 centos:6.8 /bin/bash

docker run -it --network=shadownet --ip=172.18.0.13 centos:6.8 /bin/bash

修改镜像（由于centos没有ping工具包，在基础包上安装后，提交成一个版本）

docker run -it --network=shadownet --ip=172.18.0.12 centos:6.8 /bin/bash

[root@e2bdf95d0658 /]# yum install iputils -y && exit

修改的镜像历史为 e2bdf95d0658 并提交成centos:6.8.v1 版本

docker commit -m "Added ping " -a "Docker Centosping" e2bdf95d0658 centos:6.8.v1

从提交版再进入

docker run -it --network=shadownet --ip=172.18.0.12 centos:6.8.v1 /bin/bash

[root@56ddbd3270b2 /]# ping www.baidu.com
