Kubernetes-在Kubernetes集群上搭建HBase集群-原创手记-慕课网

创建HBase镜像

配置文件包含core-site.xml、hbase-site.xml、hdfs-site.xml和yarn-site.xml，因为我这里是基于我之前搭建和zookeeper和Hadoop环境进行的，所以配置文件里面很多地方都是根据这两套环境做的，如果要搭建高可用的HBase集群，需要另外做镜像，当前镜像的配置不支持。

core-site.xml

把这些文件放入同一级目录，然后使用命令创建镜像

docker build -t leo/hbase:1.2.6.1 .

创建成功后通过通过命令【docker images】就可以查看到镜像了
【注意】，这里有一个坑，【start-kubernetes-hbase.sh】文件的格式，如果该文件是在Windows机器上创建的，默认的格式会是doc，如果不将格式修改为unix，就会报错【/bin/bash^M: bad interpreter: No such file or directory】，导致该脚本文件在Linux上无法运行，修改的方法很简单，使用vim命令修改文件，然后按下【ESC】，输入【:set ff=unix】，然后回车，wq保存。

编写yaml文件

hbase.yaml

创建服务和POD

kubectl create -f hbase.yaml

webp

create pods

分别查看POD和service

kubectl get po -o wide

webp

pods

kubectl get svc -o wide

webp

service
