centos6使用docker部署zookeeper操作示例

本文实例讲述了centos6使用docker部署zookeeper操作。分享给大家供大家参考，具体如下：

目录结构：

/zookeeper
    /Dockerfile
    /start.sh
    /Readme
    /zookeeper-3.4.10.tar.gz

Dockerfile

FROM centos
MAINTAINER qiongtao.li hnatao@126.com
ADD ./zookeeper-3.4.10.tar.gz /opt
ADD ./start.sh /start.sh
ENV ZOO_PORT=2181\
 ZOO_DIR=/opt/zookeeper \
 ZOO_DATA_DIR=/data/zookeeper/data
 ZOO_DATA_LOG_DIR=/data/zookeeper/logs
RUN echo "Asia/shanghai" > /etc/timezone \
 && cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
 && yum -y install java \
 && mkdir -p "$ZOO_DATA_DIR" \
 && mkdir -p "$ZOO_DATA_LOG_DIR" \
 && mv /opt/zookeeper-3.4.10 "$ZOO_DIR"
VOLUME ["$ZOO_DATA_DIR"]
EXPOSE $ZOO_PORT
ENV PATH=$PATH:$ZOO_DIR/bin
ENTRYPOINT ["sh", "/start.sh"]

start.sh

#!/bin/bash
CONF=${ZOO_DIR}/conf/zoo.cfg
cp -a ${ZOO_DIR}/conf/zoo_sample.cfg $CONF
sed -i "s|dataDir=/tmp/zookeeper|dataDir=${ZOO_DATA_DIR}|g" $CONF
sed -i "s|clientPort=2181|clientPort=${ZOO_PORT}|g" $CONF
echo "dataLogDir=${ZOO_DATA_LOG_DIR}" >> $CONF
for server in $ZOO_SERVERS; do
 echo "$server" >> $CONF
done
if [ ! -f "$ZOO_DATA_DIR/myid" ]; then
 echo "${ZOO_MY_ID:-1}" > "$ZOO_DATA_DIR/myid"
fi
zkServer.sh start-foreground

Readme

docker rm -f zk
docker rmi -f zk
docker build -t zk .
docker run -d \
 -p 2181:2181 \
 --name zk \
  -v /data:/data \
 zk
docker ps -a
docker logs -f zk

测试安装部署

cat Readme|while read line; do $line; done
