在kubernetes上部署zookeeper,kafka集群

本文采用网上镜像:mirrorgooglecontainers/kubernetes-zookeeper:1.0-3.4.10

准备共享存储:nfs,glusterfs,seaweed或其他,并在node节点挂载

本次采用seaweed分布式文件系统

node节点挂载:

./weed mount -filer=192.168.11.103:8801 -dir=/data/ -filer.path=/ &

 

[root@k8s-master sts]# kubectl get nodes -o wide
NAME         STATUS   ROLES    AGE   VERSION   INTERNAL-IP      EXTERNAL-IP   OS-IMAGE                KERNEL-VERSION          CONTAINER-RUNTIME

创建pv

使用本地目录创建pv, 确定node节点已经挂载共享存储..使用本地目录也可以

[root@k8s-master sts]# cat zk-pv.yaml 
kind: PersistentVolume

  name: pv-zk1
  namespace: bigdata
