本文實例講述了centos6使用docker部署kafka項目的方法。分享給大家供大家參考，具體如下：
目錄結構：
/kafka
/Dockerfile
/start.sh
/Readme
/kafka_2.11-0.10.2.1.tgz
Dockfile
FROM centos
MAINTAINER qiongtao.li hnatao@126.com
ADD ./kafka_2.11-0.10.2.1.tgz /opt
ADD ./start.sh /start.sh
ENV KAFKA_PORT=9092\
KAFKA_DIR=/opt/kafka \
KAFKA_DATA_DIR=/data/kafka
RUN echo "Asia/shanghai" > /etc/timezone \
&& cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& yum -y install java \
&& mkdir -p $KAFKA_DATA_DIR \
&& mv /opt/kafka_2.11-0.10.2.1 $KAFKA_DIR
EXPOSE $KAFKA_PORT
ENV PATH=$PATH:$KAFKA_DIR/bin
ENTRYPOINT ["sh", "/start.sh"]
start.sh
conf=$KAFKA_DIR/config/server.properties
sed -i "s|broker.id=0|broker.id=${BROKER_ID:-1}|g" $conf
sed -i "s|#delete.topic.enble=true|delete.topic.enble=true|g" $conf
sed -i "s|log.dirs=/tmp/kafka-logs|log.dirs=${KAFKA_DATA_DIR}|g" $conf
sed -i "s|#advertised.listeners=PLAINTEXT://your.host.name:9092|advertised.listeners=PLAINTEXT://${KAFKA_HOST}:${KAFKA_PORT:-9092}|g" $conf
sed -i "s|zookeeper.connect=localhost:2181|zookeeper.connect=${ZOOKEEPER_HOST}:${ZOOKEEPER_PORT:-2181}|g" $conf
sh kafka-server-start.sh $conf
Readme
docker rm -f kafka
docker rmi -f kafka
docker build -t kafka .
docker run -d \
-p 9092:9092 \
--name kafka \
-e KAFKA_HOST=101.201.111.163 \
-e ZOOKEEPER_HOST=10.171.8.236 \
-e BROKER_ID=1 \
-v /data:/data \
kafka
docker ps -a
docker logs -f kafka
說明：KAFKA_HOST=宿主機IP，其對應配置文件的advertised.listeners
測試安裝部署
cat Readme|while read line; do $line; done

希望本文所述對大家Docker容器使用有所幫助。
