一、velero介绍
Velero 是由vmware公司团队研发开源工具，用于安全地备份、恢复和迁移 Kubernetes 集群和持久卷。它可以在本地和公共云中运行。Velero 由一个在您的 Kubernetes 集群中作为部署运行的服务器进程和一个命令行界面 (CLI) 组成，DevOps 团队和平台操作员可通过该界面配置计划备份、触发临时备份、执行恢复等。官网地址：https://velero.io/
Velero备份流程
整体架构
二、准备minio存储环境
1、安装minio存储
docker pull minio/minio:latest docker run -p 9000:9000 -p 9090:9090 \ --net=host \ --name minio \ -d --restart=always \ -e "MINIO_ACCESS_KEY=admin" \ -e "MINIO_SECRET_KEY=minio123" \ -v /home/minio/data:/data \ -v /home/minio/config:/root/.minio \ minio/minio server \ /data --console-address ":9090" -address ":9000"
[root@easzlab-minio-01 ~]# netstat -tnlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 127.0.0.1:40963 0.0.0.0:* LISTEN 737/containerd tcp 0 0 127.0.0.53:53 0.0.0.0:* LISTEN 669/systemd-resolve tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 830/sshd: /usr/sbin tcp 0 0 127.0.0.1:6010 0.0.0.0:* LISTEN 1437/sshd: root@pts tcp6 0 0 :::9000 :::* LISTEN 5020/minio tcp6 0 0 :::22 :::* LISTEN 830/sshd: /usr/sbin tcp6 0 0 ::1:6010 :::* LISTEN 1437/sshd: root@pts tcp6 0 0 :::9090 :::* LISTEN 5020/minio [root@easzlab-minio-01 ~]#
admin minio123
2、创建velerodata Buckets
3、在master-01节点部署velero
下载安装包 wget https://github.com/vmware-tanzu/velero/releases/download/v1.8.1/velero-v1.8.1-linux-amd64.tar.gz tar -xvzf velero-v1.8.1-linux-amd64.tar.gz mv velero /usr/local/bin
4、配置velero认证环境
mkdir /data/velero -p cd /data/velero root@easzlab-k8s-master-01:/data/velero# cat velero-auth.txt [default] aws_access_key_id = admin aws_secret_access_key = minio123
5、将velero安装到k8s集群
root@easzlab-k8s-master-01:/data/velero# kubectl create ns velero-system namespace/velero-system created root@easzlab-k8s-master-01:/data/velero# velero --kubeconfig /root/.kube/config \ > install \ > --provider aws \ > --plugins velero/velero-plugin-for-aws:v1.3.1 \ > --bucket velerodata \ > --secret-file ./velero-auth.txt \ > --use-volume-snapshots=false \ > --namespace velero-system \ > --backup-location-config region=minio,s3ForcePathStyle="true",s3Url=http://172.16.88.170:9000 CustomResourceDefinition/backups.velero.io: attempting to create resource CustomResourceDefinition/backups.velero.io: attempting to create resource client CustomResourceDefinition/backups.velero.io: created CustomResourceDefinition/backupstoragelocations.velero.io: attempting to create resource CustomResourceDefinition/backupstoragelocations.velero.io: attempting to create resource client CustomResourceDefinition/backupstoragelocations.velero.io: created CustomResourceDefinition/deletebackuprequests.velero.io: attempting to create resource CustomResourceDefinition/deletebackuprequests.velero.io: attempting to create resource client CustomResourceDefinition/deletebackuprequests.velero.io: created CustomResourceDefinition/downloadrequests.velero.io: attempting to create resource CustomResourceDefinition/downloadrequests.velero.io: attempting to create resource client CustomResourceDefinition/downloadrequests.velero.io: created CustomResourceDefinition/podvolumebackups.velero.io: attempting to create resource CustomResourceDefinition/podvolumebackups.velero.io: attempting to create resource client CustomResourceDefinition/podvolumebackups.velero.io: created CustomResourceDefinition/podvolumerestores.velero.io: attempting to create resource CustomResourceDefinition/podvolumerestores.velero.io: attempting to create resource client CustomResourceDefinition/podvolumerestores.velero.io: created CustomResourceDefinition/resticrepositories.velero.io: attempting to create resource CustomResourceDefinition/resticrepositories.velero.io: attempting to create resource client CustomResourceDefinition/resticrepositories.velero.io: created CustomResourceDefinition/restores.velero.io: attempting to create resource CustomResourceDefinition/restores.velero.io: attempting to create resource client CustomResourceDefinition/restores.velero.io: created CustomResourceDefinition/schedules.velero.io: attempting to create resource CustomResourceDefinition/schedules.velero.io: attempting to create resource client CustomResourceDefinition/schedules.velero.io: created CustomResourceDefinition/serverstatusrequests.velero.io: attempting to create resource CustomResourceDefinition/serverstatusrequests.velero.io: attempting to create resource client CustomResourceDefinition/serverstatusrequests.velero.io: created CustomResourceDefinition/volumesnapshotlocations.velero.io: attempting to create resource CustomResourceDefinition/volumesnapshotlocations.velero.io: attempting to create resource client CustomResourceDefinition/volumesnapshotlocations.velero.io: created Waiting for resources to be ready in cluster...

#!/bin/bash
NS_NAME=$(kubectl get ns |awk '{if(NR>1){print $1}}')
DATE=$(date +%Y%m%d%H%M%S)
cd /data/velero/
for i in $NS_NAME;do
/usr/local/bin/velero backup create ${i}-ns-backup-${DATE} \
--include-cluster-resources=true \
--include-namespaces ${i} \
--kubeconfig=/root/.kube/config \

三、恢复备份测试
1、删除备份pod
root@easzlab-deploy:~/pod-test# kubectl get pod -A NAMESPACE NAME READY STATUS RESTARTS AGE kube-system calico-kube-controllers-5c8bb696bb-fxbmr 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-2qtfm 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-8l78t 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-9b75m 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-k75jh 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-kmbhs 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-lxfk9 1/1 Running 1 (2d10h ago) 6d21h kube-system coredns-69548bdd5f-6df7j 1/1 Running 1 (2d10h ago) 6d9h kube-system coredns-69548bdd5f-nl5qc 1/1 Running 1 (2d10h ago) 6d9h kubernetes-dashboard dashboard-metrics-scraper-8c47d4b5d-2d275 1/1 Running 1 (2d10h ago) 6d9h kubernetes-dashboard kubernetes-dashboard-5676d8b865-6l8n8 1/1 Running 1 (2d10h ago) 6d9h linux70 linux70-tomcat-app1-deployment-5d666575cc-kbjhk 1/1 Running 1 (2d10h ago) 4d10h myserver linux70-nginx-deployment-55dc5fdcf9-58ll2 1/1 Running 1 (2d10h ago) 4d10h myserver linux70-nginx-deployment-55dc5fdcf9-6xcjk 1/1 Running 1 (2d10h ago) 4d10h myserver linux70-nginx-deployment-55dc5fdcf9-cxg5m 1/1 Running 1 (2d10h ago) 4d10h myserver linux70-nginx-deployment-55dc5fdcf9-gv2gk 1/1 Running 1 (2d10h ago) 4d10h velero-system velero-858b9459f9-5mxxx 1/1 Running 0 23m root@easzlab-deploy:~/pod-test# kubectl delete -f nginx.yaml deployment.apps "linux70-nginx-deployment" deleted service "linux70-nginx-service" deleted root@easzlab-deploy:~/pod-test# kubectl get pod -A NAMESPACE NAME READY STATUS RESTARTS AGE kube-system calico-kube-controllers-5c8bb696bb-fxbmr 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-2qtfm 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-8l78t 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-9b75m 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-k75jh 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-kmbhs 1/1 Running 1 (2d10h ago) 6d21h kube-system calico-node-lxfk9 1/1 Running 1 (2d10h ago) 6d21h kube-system coredns-69548bdd5f-6df7j 1/1 Running 1 (2d10h ago) 6d9h kube-system coredns-69548bdd5f-nl5qc 1/1 Running 1 (2d10h ago) 6d9h kubernetes-dashboard dashboard-metrics-scraper-8c47d4b5d-2d275 1/1 Running 1 (2d10h ago) 6d9h kubernetes-dashboard kubernetes-dashboard-5676d8b865-6l8n8 1/1 Running 1 (2d10h ago) 6d9h linux70 linux70-tomcat-app1-deployment-5d666575cc-kbjhk 1/1 Running 1 (2d10h ago) 4d10h velero-system velero-858b9459f9-5mxxx 1/1 Running 0 24m root@easzlab-deploy:~/pod-test#
2、使用备份数据进行恢复

3、卸载安装
