Kafka+Zookeeper+Storm的docker化
因为项目需要，需要把kafka、zookeeper、storm等服务组件docker化，在借鉴相关的开源dockerfile文件后，终于完成，以此记录。
1.首先是建立基础的Linux镜像，针对本项目做了定制。

· 其中jq需要从网上下载放在同一目录下。
2.进行kafka的环境安装[参考github项目->https://github.com/wurstmeister/kafka-docker] ``` FROM centos ARG kafka_version=1.0.0 ARG scala_version=2.12 ARG glibc_version=2.27-r0 ENV KAFKA_VERSION=$kafka_version \ SCALA_VERSION=$scala_version \ KAFKA_HOME=/opt/kafka \ GLIBC_VERSION=$glibc_version ENV PATH=${PATH}:${KAFKA_HOME}/bin COPY download-kafka.sh start-kafka.sh broker-list.sh create-topics.sh /tmp/ RUN chmod a+x /tmp/*.sh \ && mv /tmp/start-kafka.sh /tmp/broker-list.sh /tmp/create-topics.sh /usr/bin \ && sync && /tmp/download-kafka.sh \ && tar xfz /tmp/kafka_${SCALA_VERSION}-${KAFKA_VERSION}.tgz -C /opt \ && rm /tmp/kafka_${SCALA_VERSION}-${KAFKA_VERSION}.tgz \ && ln -s /opt/kafka_${SCALA_VERSION}-${KAFKA_VERSION} /opt/kafka \ && rm /tmp/* -rf VOLUME ["/kafka"] CMD ["start-kafka.sh"] ``` - 相关脚本请去github下载【本dockerfile也是参考该开源项目->https://github.com/wurstmeister/kafka-docker】 3.zookeeper->[参考项目->https://github.com/wurstmeister/zookeeper-docker] ``` FROM centos ENV ZOOKEEPER_VERSION 3.4.12 RUN wget -q http://mirrors.tuna.tsinghua.edu.cn/apache/zookeeper/zookeeper-${ZOOKEEPER_VERSION}/zookeeper-${ZOOKEEPER_VERSION}.tar.gz && \ wget -q https://www.apache.org/dist/zookeeper/KEYS && \ wget -q https://www.apache.org/dist/zookeeper/zookeeper-${ZOOKEEPER_VERSION}/zookeeper-${ZOOKEEPER_VERSION}.tar.gz.asc && \ wget -q https://www.apache.org/dist/zookeeper/zookeeper-${ZOOKEEPER_VERSION}/zookeeper-${ZOOKEEPER_VERSION}.tar.gz.md5 RUN md5sum -c zookeeper-${ZOOKEEPER_VERSION}.tar.gz.md5 && \ gpg --import KEYS && \ gpg --verify zookeeper-${ZOOKEEPER_VERSION}.tar.gz.asc RUN tar -xzf zookeeper-${ZOOKEEPER_VERSION}.tar.gz -C /opt RUN cp /opt/zookeeper-${ZOOKEEPER_VERSION}/conf/zoo_sample.cfg /opt/zookeeper-${ZOOKEEPER_VERSION}/conf/zoo.cfg ENV JAVA_HOME $JAVA_HOME ENV ZK_HOME /opt/zookeeper-${ZOOKEEPER_VERSION} RUN sed -i "s|/tmp/zookeeper|$ZK_HOME/data|g" $ZK_HOME/conf/zoo.cfg; mkdir $ZK_HOME/data EXPOSE 2181 2888 3888 WORKDIR /opt/zookeeper-${ZOOKEEPER_VERSION} VOLUME ["/opt/zookeeper-${ZOOKEEPER_VERSION}/conf", "/opt/zookeeper-${ZOOKEEPER_VERSION}/data"] CMD /usr/sbin/sshd && sed -i -r 's|#(log4j.appender.ROLLINGFILE.MaxBackupIndex.*)|\1|g' $ZK_HOME/conf/log4j.properties && \ sed -i -r 's|#autopurge|autopurge|g' $ZK_HOME/conf/zoo.cfg && \ /opt/zookeeper-${ZOOKEEPER_VERSION}/bin/zkServer.sh start-foreground ``` 4.storm ->[参考项目-> https://github.com/wurstmeister/storm-docker] ``` FROM centos RUN wget -q -O - https://zcc2018.oss-cn-beijing.aliyuncs.com/apache-storm-1.2.1.tar.gz | tar -xzf - -C /opt ENV STORM_HOME /opt/apache-storm-1.2.1 RUN groupadd storm; useradd --gid storm --home-dir /home/storm --create-home --shell /bin/bash storm; chown -R storm:storm $STORM_HOME; mkdir /var/log/storm ; chown -R storm:storm /var/log/storm RUN ln -s $STORM_HOME/bin/storm /usr/bin/storm ADD storm.yaml $STORM_HOME/conf/storm.yaml ADD cluster.xml $STORM_HOME/logback/cluster.xml ADD config-supervisord.sh /usr/bin/config-supervisord.sh ADD start-supervisor.sh /usr/bin/start-supervisor.sh RUN chmod a+x /usr/bin/config-supervisord.sh && \ chmod a+x /usr/bin/start-supervisor.sh RUN mkdir /etc/supervisor/conf.d/ -p ``` 5.Docker-compose.yml【仅供参考】 ``` version: '3' services: #zookeeper zookeeper: image: zookeeper ports: - "2181:2181" - "10122:22" networks: - analyser_cluster #kafka kafka: image: kafka ports: - "9092:9092" environment: KAFKA_ADVERTISED_HOST_NAME: "kafka" KAFKA_ADVERTISED_PORT: "9092" KAFKA_ZOOKEEPER_CONNECT: "zk:2181" volumes: - /var/run/docker.sock:/var/run/docker.sock links: - zookeeper:zk depends_on: - zookeeper networks: - analyser_cluster #storm ->nimbus nimbus: image: storm_nimbus ports: - "13773:3773" - "13772:3772" - "16627:6627" - "10322:22" links: - zookeeper:zk depends_on: - zookeeper networks: - analyser_cluster #storm ->supervisor supervisor: image: storm_supervisor ports: - "8000:8000" - "10422:22" links: - nimbus:nimbus - zookeeper:zk depends_on: - zookeeper networks: - analyser_cluster #storm -> ui ui: image: storm_ui ports: - "18080:8080" - "10522:22" links: - nimbus:nimbus - zookeeper:zk depends_on: - zookeeper networks: - analyser_cluster networks: analyser_cluster: ``` > 主要是针对开源项目做了针对自己项目需求的定制，以及将一些软件源替换为国内源。还有针对docker过程中一些无法运行的地方进行了修改， > 其实本项目还有elk集群，redis，mysql等与上述kafka、storm的链接，但是因为时间有限、所以没有发出来，等后续有时间再补上吧。
