造个轮子 - kafka镜像

说明

1. 镜像基于xiaows/debian8-jdk8-ssh:2.0
2. kafka版本2.11

安装kafka

1. 下载kafka到本地
2. 编写dockerfile 2.1 通过echo命令在dockerfile中直接写入相关配置文件 2.2 删除*.cmd,并将*.sh赋予可执行权限 2.3 在/root目录下生成一个启动kafka集群的脚本cluster-kafka.sh 2.4 拷贝当前dockerfile到镜像中

COPY ./Dockerfile-kafka211-jdk /root/

构建镜像

docker build -f Dockerfile-kafka211-jdk -t xiaows/kafka211-jdk:2.0 .

接下来就可以用之前那个启动集群镜像脚本来启动容器和集群啦~

./start-cluster.sh xiaows/kafka211-jdk:2.0 kafka ./cluster.sh start
