Rook is an open source cloud-native storage orchestrator, providing the platform, framework, and support for Ceph storage to natively integrate with cloud-native environments.1. 說明
因香橙派和樹莓派資源所限，轉移到基于VirtualBox建立的VMs繼續(xù)實踐。
虛擬機環(huán)境列表:
| Host Name | IP | 配置 | 備注 |
| k8s-c0-master0 | 10.0.3.6 | Ubuntu 22.04.3 LTS 8核32G, 200G(sda) + 100G(sdb) | 虛擬機 |
| k8s-c0-node0 | 10.0.3.7 | Ubuntu 22.04.3 LTS 4核8G, 200G(sda) + 100G(sdb) | ... |
| k8s-c0-node1 | 10.0.3.8 | Ubuntu 22.04.3 LTS 4核8G, 200G(sda) + 100G(sdb) | ... |
2.?準備工作
- 下載 ubuntu-22.04.2-live-server-amd64.iso，并映射到啟動光盤
- 虛擬機設置雙網(wǎng)卡，1作橋接(同網(wǎng)訪問)，1作NAT網(wǎng)絡（K8s內(nèi)網(wǎng)）
- 安裝時選擇鏡像（重要）https://mirrors.aliyun.com/ubuntu
- 初始化K8s環(huán)境
- 為避免CTR拉取鏡像失敗，設置容器代理，編輯 /lib/systemd/system/containerd.service
[Service] Environment="HTTP_PROXY=http://192.168.0.108:1081" Environment="HTTPS_PROXY=http://192.168.0.108:1081" Environment="NO_PROXY=aliyun.com,aliyuncs.com,huaweicloud.com,k8s-master-0,k8s-master-1,k8s-worker-0,localhost,127.0.0.1,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16"systemctl daemon-reload && systemctl restart containerd
3. 方案及安裝步驟
3.1 Rook
Rook is an open source cloud-native storage orchestrator, providing the platform, framework, and support for Ceph storage to natively integrate with cloud-native environments.
3.2 安裝要求
- Raw devices (no partitions or formatted filesystems)
- Raw partitions (no formatted filesystem)?
- LVM Logical Volumes (no formatted filesystem)
- Persistent Volumes available from a storage class in?
block?mode
一句話：有個裸盤 （100G /dev/sdb）
保證至少3個節(jié)點，去掉污點
kubectl taint nodes --all node-role.kubernetes.io/control-plane-3.3 安裝步驟
1. 獲取rook倉庫到安裝路徑，如：/k8s_apps/rook
git clone --single-branch --branch v1.12.6 https://github.com/rook/rook.git2. 編寫安裝腳本，/k8s_apps/scripts/k8s-rook-ceph.sh
#!/bin/bash
kubectl apply -f /k8s_apps/rook/deploy/examples/crds.yaml
kubectl apply -f /k8s_apps/rook/deploy/examples/common.yaml
kubectl apply -f /k8s_apps/rook/deploy/examples/operator.yaml
kubectl -n rook-ceph get pod
kubectl apply -f /k8s_apps/rook/deploy/examples/cluster.yaml
3. 編寫刪除腳本，/k8s_apps/scripts/rook-ceph-delete.sh
#!/bin/bash
kubectl delete -f /k8s_apps/rook/deploy/examples/wordpress.yaml
kubectl delete -f /k8s_apps/rook/deploy/examples/mysql.yaml
kubectl delete -n rook-ceph cephblockpool replicapool
kubectl delete storageclass rook-ceph-block
kubectl delete -f /k8s_apps/rook/deploy/examples/csi/cephfs/kube-registry.yaml
kubectl delete storageclass csi-cephfs
kubectl -n rook-ceph patch cephcluster rook-ceph --type merge -p '{"spec":{"cleanupPolicy":{"confirmation":"yes-really-destroy-data"}}}'
kubectl -n rook-ceph delete cephcluster rook-ceph
kubectl -n rook-ceph get cephcluster
kubectl delete -f /k8s_apps/rook/deploy/examples/operator.yaml
kubectl delete -f /k8s_apps/rook/deploy/examples/common.yaml
kubectl delete -f /k8s_apps/rook/deploy/examples/crds.yaml4. 執(zhí)行安裝，一切正常的話，如下圖，不正常的話，執(zhí)行刪除腳本，排除問題后重來。文章來源：http://www.zghlxwxcb.cn/news/detail-720766.html
