statefulset 这里采用的部署方式如下 使用自定义的 debian 镜像作为基础镜像 目的1可以塞很多排查工具进去目的2一个统一的基础镜像方便维护目的3centos 后期不维护了避免尴尬场景 通过 gfs 做数据持久化通过 pv 和 pvc 的形式将二进制文件挂载到 pod 内kafka 的二进制文件里面带有了 zookeeper这里就只使用 kafka 的二进制文件 kafka 二进制文件下载地址 构建 debian 基础镜像 FROM debian:11ENV TZAsia/Shanghai ENV LANGen_US.UTF-8RUN echo /etc/apt/sources.list \for i in stable stable-proposed-updates stable-updates;\do \echo deb

“Recommends” 部分。如果您不需要所有推荐的软件包这可以帮助保持安装的系统更加精简 构建镜像 docker build -t debian11_amd64_base:v1.0 .部署 zookeeper 配置 namespace 我的环境做了软连接下面的命令中出现的 k 表示 kubectl 命令 k create ns bigdata配置 gfs 的 endpoints 正如开头提到的我这边使用的是 gfs 来做的持久化需要通过 endpoints 来暴露给 k8s 集群内部使用相关的资料可以看我其他的文章 CentOS 7.6 部署 GlusterFS 分布式存储系统Kubernetes 集群使用 GlusterFS 作为数据持久化存储 --- apiVersion: v1 kind: Endpoints metadata:annotations:name:
