Docker-Compose配置zookeeper+KaFka+CMAK简单集群

1. 本地DNS解析管理

# 编辑hosts文件
sudo nano /etc/hosts
# 添加以下三个主机IP
192.168.186.77 zoo1 k1
192.168.186.18 zoo2 k2
192.168.186.216 zoo3 k3

注：zoo1是192.168.186.77的别名，zoo2是192.168.186.18的别名，zoo3是192.168.186.126的别名，IP自行修改即可，其他配置可以直接使用。

2. 项目结构

注：本文将宿主机的当前目录下的data目录挂载到容器的/data目录，data目录是需要自己创建且跟docker-compose.yml是平级关系，读者可以根据需求自行调整配置文件。

3. docker-compose.yml (Zookeeper集群)

4.4 标红代码的作用

docker-compose up -d命令会启动docker-compose.yml文件中定义的所有服务。如果服务所依赖的镜像尚未被下载，Docker Compose会自动从Docker Hub或指定的镜像仓库拉取，-d 参数确保容器在后台运行。docker-compose logs查看正在运行的服务的日志。docker-compose ps查看容器的状态。docker-compose exec zookeeper zkServer.sh status获取 Zookeeper 实例的当前状态和角色信息
