# 【云原生 | Kubernetes 系列】—K8S部署kafka集群

🍇 一:基础说明

Kafka和zookeeper是两种典型的有状态的应用集群服务。首先kafka和zookeeper都需要存储盘来保存有状态信息；其次kafka和zookeeper每一个实例都需要有对应的实例Id (Kafka需broker.id, zookeeper需要my.id) 来作为集群内部每个成员的标识，集群内节点之间进行内部通信时需要用到这些标识。

对于这类服务的部署，需要解决两个大的问题：一个是状态保存，另一个是集群管理 (多服务实例管理)。kubernetes中提的StatefulSet方便了有状态集群服务在上的部署和管理。通常来说，通过下面三个手段来实现有状态集群服务的部署：
  • 通过Init Container来做集群的初始化工 作。
  • 通过Headless Service来维持集群成员的稳定关系。
  • 通过Persistent Volume和Persistent Volume Claim提供网络存储来持久化数据。
因此，在K8S集群里面部署类似kafka、zookeeper这种有状态的服务，不能使用Deployment，必须使用StatefulSet来部署，有状态简单来说就是需要持久化数据，比如日志、数据库数据、服务状态等。

StatefulSet 应用场景：

  • 稳定的持久化存储，即Pod重新调度后还是能访问到相同的持久化数据，基于PVC来实现
  • 稳定的网络标志，即Pod重新调度后其PodName和HostName不变，基于Headless Service（即没有Cluster IP的Service）来实现
  • 有序部署，有序扩展，即Pod是有顺序的，在部署或者扩展的时候要依据定义的顺序依次依次进行（即从0到N-1，在下一个Pod运行之前所有之前的Pod必须都是Running和Ready状态），基于init containers来实现
  • 有序收缩，有序删除（即从N-1到0）

StatefulSet组成：

  • 用于定义网络标志（DNS domain）的Headless Service
  • 用于创建PersistentVolumes的volumeClaimTemplates
  • 定义具体应用的StatefulSet

StatefulSet中每个Pod的DNS格式为：

statefulSetName-{0..N-1}.serviceName.namespace.svc.cluster.local，其中：

  • statefulSetName为StatefulSet的名字
  • 0..N-1为Pod所在的序号，从0开始到N-1
  • serviceName为Headless Service的名字
  • namespace为服务所在的namespace，Headless Servic和StatefulSet必须在相同的namespace
  • svc.cluster.local为K8S的Cluster Domain集群根域

🍋 准备

1:准备存储,这里我用ceph,需要自己准备存储 2:下载包:kafka_2.12-2.8.2.tgz

创建KAFKA集群

这里要求能在外部访问到Kafka集群，需要配置三个外网地址，或者一个外网地址+三个端口，依次代理对应后端三个Kafka的Pod容器实例；外网连接Kafka，需要配置使用advertised.listeners监听器；

  • advertised_listeners 监听器是对外暴露的服务端口，kafka组件之间通讯用的是 listeners；
  • advertised_listeners 监听器会注册在 zookeeper 中；
  • 当我们通过对"<公网ip>:端口"请求建立连接，kafka服务器会通过 zookeeper 中注册的监听器，找到定义的公网监听器（默认监听器是PLAINTEXT、也可以自定义），然后通过listeners中找到对应的"通讯ip和端口";

1: kafka kafka_2.12-2.8.2版本的Dockerfile镜像制作

FROM openjdk:8
RUN rm -f /etc/localtime \
&& ln -sv /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \
&& echo "Asia/Shanghai" > /etc/timezone

ENV LANG en_US.UTF-8
ENV KAFKA_DATA_DIR /var/lib/kafka/data
ENV JAVA_HOME /usr/local/openjdk-8
ENV KAFKA_HOME /opt/kafka
ENV PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/kafka/bin

COPY kafka_2.12-2.8.2.tgz /opt/kafka_2.12-2.8.2.tgz
WORKDIR /opt/
RUN tar -zxvf kafka_2.12-2.8.2.tgz && rm -rf kafka_2.12-2.8.2.tgz && mv kafka_2.12-2.8.2 kafka && mkdir -p /var/lib/kafka/data
CMD ["/bin/bash"]

2:制作镜像并上传到Harbor

docker build -t 127.0.0.1/ops/kafka:v2.12-2.8.2 .
docker push 127.0.0.1/ops/kafka:v2.12-2.8.2
