云原生|kubernetes|kubernetes资源备份和集群迁移神器velero的部署和使用
2023-12-30 23:57:37
前言：
kubernetes集群需要灾备吗？kubernetes需要迁移吗？?答案肯定是需要的
那么，如何做kubernetes灾备和迁移呢？当然了，有很多的方法，例如，自己编写shell脚本，或者使用专业的灾备工具，但shell编写复杂，也可能会有所遗漏，对比其它的kubernetes专业备份软件，很多备份条件苛刻，安装部署困难，或者恢复只能一把梭，也就是备份和恢复不太灵活的那种样子，比如，Kasten K10?就部署比较麻烦（过于重），备份也不太灵光的样子。
velero?这个备份工具比较好，优点有?部署简单，快速，备份范围可定制，例如只备份deployment这样的资源，只备份某个namespace等等，也就是备份范围灵活，可控，恢复速度也是很快的，在kubernetes集群迁移方面也是基本没有缺点，只是在安全性方面可能不是特别的确定，因为velero主要是基于对象存储插件来备份的，一般是obs，oss或者minio，而这些面向对象存储的安全性无法确定的保障，关键的是该软件是go语言编写的，天生和kubernetes这样的云原生对味。
下面本文将就velero的部署和基本使用做一个介绍。
一，
示例环境介绍
VMware虚拟机，四台服务器，IP地址分别是192.168.123.11，192.168.123.12，192.168.123.13，192.168.123.14? 操作系统是centos-7.5 ，内核版本是3.10，?kubernetes集群是通过kubekey部署的，版本是1.23.16，?三个master节点，一个工作节点：

二，
velero的强依赖
前面也说了velero需要对象存储插件或者服务，这里可以是oss，obs，minio这样的常用的对象存储，本例既然是做实验，当然不会搞一个云厂商主流的oos，显然部署oos是不现实的嘛，那么，minio还是可以搞一搞的，前两天已经把部署minio分布式集群写过了，在这里就不重复了，见我的博客：

三，
velero的下载和部署
下载地址：https://github.com/vmware-tanzu/velero/releases?page=4??
本例使用的版本是velero-v1.9.4-linux-amd64.tar.gz
部署：
解压文件后，扔到/usr/bin/目录下即可，确认版本，最好是放置在kubernetes集群的管理节点，因为velero需要使用KUBECONFIG来获取备份所需的信息：
[root@node4 nginx-app]# velero version
Client:
Version: v1.9.4
Git commit: ddfc962282783cf2f0bf364c9d721f88fa4cc058
Server:
Version: v1.9.4
该命令可以像kubelet一样设置自动补全，Linux下的自动补全非常简单，前提是安装bash_complete：
velero completion bash >/etc/bash_completion.d/veleroIf you have an alias for velero, you can extend shell completion to work with that alias（如果需要简化命令和自动补全，执行下面的命令即可）:
echo 'alias v=velero' >>~/.bashrc
echo 'complete -F __start_velero v' >>~/.bashrc下面是通过命令生成部署清单文件，一般不建议直接安装，毕竟留一个安装文件也好及时调整修改嘛(--dry-run?然后输出为yaml)：
minio的console用户和密码
[root@node4 ~]# cat credentials-velero
[default]
aws_access_key_id=minioadmin
aws_secret_access_key=minioadmin
?需要注意，kubernetes集群的版本必须是1.16及以上，如果是使用minio，下面的命令不需要更改，s3url根据实际情况填写，minio登录web管理界面，创建一个桶，桶名称为velero?就可以了
velero install --use-restic --provider aws --plugins velero/velero-plugin-for-aws:v1.5.0 --bucket velero --secret-file /root/credentials-velero --use-volume-snapshots=false --backup-location-config region=minio,s3ForcePathStyle="true",s3Url=http://192.168.123.11:39111 --dry-run -o yaml > velero.yaml

"key", the operator is "In", and the values array contains

apply以上的部署清单文件，很快的就可以安装完毕了，查看如下pod，正常运行表示安装完毕：

四，
kubernetes集群全量资源备份
[root@node4 ~]# v backup create test
Backup request "test" submitted successfully.
Run `velero backup describe test` or `velero backup logs test` for more details.
查看是否备份成功（只有complete是成功的，其它的备份是不可用的）：

查看备份详情：

恢复：
计划恢复的目标是下面的这些
[root@node4 nginx-app]# k get po -n nginx-example
NAME READY STATUS RESTARTS AGE
nginx-deployment-5c844b66c8-7rrz8 1/1 Running 0 81s
nginx-deployment-5c844b66c8-szbg4 1/1 Running 0 81s
?现在先删除nginx-example这个命名空间：
[root@node4 nginx-app]# k delete ns nginx-example
namespace "nginx-example" deleted
开始恢复：
[root@node4 nginx-app]# v restore create --from-backup=test
Restore request "test-20231230204606" submitted successfully.
Run `velero restore describe test-20231230204606` or `velero restore logs test-20231230204606` for more details.
查看恢复状态：
可以看到，在执行恢复，稍等片刻
[root@node4 nginx-app]# v restore get
NAME BACKUP STATUS STARTED COMPLETED ERRORS WARNINGS CREATED SELECTOR
test-20231230204606 test InProgress 2023-12-30 20:46:06 +0800 CST <nil> 0 0 2023-12-30 20:46:06 +0800 CST <none>
[root@node4 nginx-app]# v restore get

查看恢复日志，没有输出表示恢复正常：
[root@node4 nginx-app]# v restore logs test-20231230204606 |grep error说明：velero的恢复策略是目标资源存在将会跳过，恢复的时候不会检查image版本等等过于细节的地方，也就是说不会覆盖回退，只有删除回退。
查看日志我们应该可以得出这个比较明显的结论：
[root@node4 nginx-app]# v restore logs test-20231230205200 |grep skip

五，
velero的部分资源备份和恢复：
单独备份指定的namespace
[root@node4 nginx-app]# v backup create test1 --include-namespaces=nginx-example
Backup request "test1" submitted successfully.
Run `velero backup describe test1` or `velero backup logs test1` for more details.
查看备份详情：
[root@node4 nginx-app]# v backup describe test1

使用此备份恢复，并查看恢复情况：
[root@node4 nginx-app]# k delete ns nginx-example
namespace "nginx-example" deleted
[root@node4 nginx-app]# v restore create --from-backup=test1
Restore request "test1-20231230212744" submitted successfully.
Run `velero restore describe test1-20231230212744` or `velero restore logs test1-20231230212744` for more details.
[root@node4 nginx-app]# k get po -n nginx-example

这个备份恢复迁移到其它namespace?nginx1：
[root@node4 nginx-app]# v restore create --from-backup=test1 --namespace-mappings nginx-example:nginx1
Restore request "test1-20231230220044" submitted successfully.
Run `velero restore describe test1-20231230220044` or `velero restore logs test1-20231230220044` for more details.

当然了，全备的test里也可以抽namespace出来恢复：
[root@node4 nginx-app]# v restore create --from-backup=test --namespace-mappings nginx-example:nginx3
Restore request "test-20231230220230" submitted successfully.
Run `velero restore describe test-20231230220230` or `velero restore logs test-20231230220230` for more details.
[root@node4 nginx-app]# v restore create --from-backup=test --namespace-mappings kube-system:nginx3
Restore request "test-20231230220613" submitted successfully.
Run `velero restore describe test-20231230220613` or `velero restore logs test-20231230220613` for more details.
[root@node4 nginx-app]# k get po -n nginx3

单独的pod备份就不需要使用velero了，直接kubectl?get?deploy -n?namespace -oyaml?就可以了
注意：
velero restore?恢复不会覆盖已有的资源，只恢复当前集群中不存在的资源。已有的资源不会回滚到之前的版本，如需要回滚，需在restore之前提前删除现有的资源。
?–include-resources
备份集群中的所有 deployments:? velero backup create <backup-name> --include-resources deployments
恢复集群中的所有 deployments 和 configmaps。? velero restore create <backup-name> --include-resources deployments,configmaps
在 namespace 中备份 deployments。? velero backup create <backup-name> --include-resources deployments --include-namespaces <namespace>
–selector
包括与 label selector 匹配的资源。velero backup create <backup-name> --selector <key>=<value>
Excludes
从备份中排除特定资源。通配符排除将被忽略。
–exclude-namespaces
Exclude kube-system from the cluster backup.? velero backup create <backup-name> --exclude-namespaces kube-system
还原期间排除两个 namespace。? velero restore create <backup-name> --exclude-namespaces <namespace1>,<namespace2>
–exclude-resources
从备份中排除 secrets:? velero backup create <backup-name> --exclude-resources secrets
排除 secrets 和 rolebindings:? velero backup create <backup-name> --exclude-resources secrets,rolebindings
?
自动计划备份：
这里说明一下，ttl过期时间可以免去一些备份文件的管理工作，当然普通的备份也可以指定这个过期时间
# 每日1点进行备份
velero create schedule <SCHEDULE NAME> --schedule="0 1 * * *"
# 每日1点进行备份，备份保留72小时
velero create schedule <SCHEDULE NAME> --schedule="0 1 * * *" --ttl 72h
# 每5小时进行一次备份
velero create schedule <SCHEDULE NAME> --schedule="@every 5h"
# 每日对 指定 namespace 进行一次备份 （如dev）
velero create schedule <SCHEDULE NAME> --schedule="@every 24h" --include-namespaces dev
[root@node4 nginx-app]# v create schedule test --schedule="0 0 * * *" --ttl=72h
Schedule "test" created successfully.
[root@node4 nginx-app]# v schedule get
NAME STATUS CREATED SCHEDULE BACKUP TTL LAST BACKUP SELECTOR
