Kubernetes----------------------------Rook Deploy CephCluster

Quickstart

 

Minimum Version

Kubernetes v1.17 or higher is supported by Rook.

CPU Architecture

Architectures released are amd64 / x86_64 and arm64.

Prerequisites

To make sure you have a Kubernetes cluster that is ready for Rook, you can follow these instructions.

In order to configure the Ceph storage cluster, at least one of these local storage options are required:

为了配置Ceph存储集群，至少需要以下一种本地存储选项:

• Raw devices (no partitions or formatted filesystems). 原始设备(没有分区或格式化文件系统)
• This requires lvm2 to be installed on the host. To avoid this dependency, you can create a single full-disk partition on the disk (see below)  Yum install -y lvm2 
• Raw partitions (no formatted filesystem)

注: 手动给每天个node节点新盘创建GPT header后，部署OSD正常！

  

parted /dev/sdb
mklabel gpt
mkpart primary 0 -1 新盘只分一个区 输入:  Ignore
q

 

 

 部署命令

$ git clone --single-branch --branch master https://github.com/rook/rook.git
cd rook/deploy/examples
kubectl create -f crds.yaml -f common.yaml -f operator.yaml
kubectl create -f cluster.yaml

 

创建rook-ceph-tools工具

kubectl -n rook-ceph exec -it deploy/rook-ceph-tools -- bash

Rook-ceph 修复工具

kubectl -n rook-ceph edit ConfigMap rook-config-override -o yaml

# config: |
#   [global]
#   mon clock drift allowed = 1

 访问Web Ceph Dashboard

 

 

 

1.
　　kubectl port-forward --address 0.0.0.0 service/rook-ceph-mgr-dashboard  40459:8443 -n rook-ceph 
　　#使用有端口转发，访问ceph-dashboard
2.
   cd rook/deploy/examples/ 
　　kubectl create -f dashboard-external-https.yaml

访问地址，注意是https，http会访问不成功
https://172.17.1.62:40459/#/dashboard

默认用户名为
admin

密码获取方式执行如下命令
kubectl -n rook-ceph get secret rook-ceph-dashboard-password -o jsonpath="{['data']['password']}" | base64 --decode && echo


Ceph Dashboard首页，点击首页小齿轮修改admin的密码

 

 

node节点硬盘osd.id 初始化错误处理

DISK="/dev/vdb"
sgdisk --zap-all --clear --mbrtogpt $DISK
