# Helm部署Velero
|
||
|
||
[官方文档](https://velero.io/docs/) [Velero客户端下载](https://github.com/vmware-tanzu/velero/releases) [Helm仓库介绍页](https://vmware-tanzu.github.io/helm-charts/) [Helm-Github仓库](https://github.com/vmware-tanzu/helm-charts/blob/main/charts/velero/README.md)
|
||
|
||
## 开始部署
|
||
|
||
> 准备 Minio 存储
|
||
>
|
||
> 示例：
|
||
>
|
||
> - 存储地址为：192.168.1.10
|
||
> - 账户/密码：minioadmin/minioadmin
|
||
> - 存储桶：backup
|
||
|
||
1. 添加 Helm 仓库
|
||
|
||
```bash
|
||
helm repo add vmware-tanzu https://vmware-tanzu.github.io/helm-charts
|
||
helm repo update
|
||
```
|
||
|
||
2. 编辑 values.yaml
|
||
|
||
```bash
|
||
vi velero-values.yaml
|
||
```
|
||
|
||
内容如下
|
||
|
||
```yaml
|
||
cleanUpCRDs: true
|
||
|
||
snapshotsEnabled: false
|
||
|
||
initContainers:
|
||
- name: velero-plugin-for-aws
|
||
image: velero/velero-plugin-for-aws:latest
|
||
imagePullPolicy: IfNotPresent
|
||
volumeMounts:
|
||
- mountPath: /target
|
||
name: plugins
|
||
|
||
configuration:
|
||
backupStorageLocation:
|
||
- name: default
|
||
provider: aws
|
||
bucket: backup
|
||
accessMode: ReadWrite
|
||
config:
|
||
region: minio-region
|
||
s3ForcePathStyle: true
|
||
s3Url: http://192.168.1.10:9000
|
||
publicUrl: http://192.168.1.10:9000
|
||
|
||
credentials:
|
||
useSecret: true
|
||
secretContents:
|
||
cloud: |
|
||
[default]
|
||
aws_access_key_id=minioadmin
|
||
aws_secret_access_key=minioadmin
|
||
|
||
# 配置定时备份任务 disabled 改为 false 即可启动定时任务(默认关闭)
|
||
# 特别参数解释:
|
||
# useOwnerReferencesInBackup: 设置为 false，表示在备份时不使用资源的 owner references 来确定哪些关联资源应该包括在备份中。如果设置为 true，Velero 会根据 Kubernetes 的 owner references 备份会自动包括关联资源。
|
||
# ttl: 设置备份的生存时间(Time To Live)。
|
||
# storageLocation: 指定备份数据存储的位置。
|
||
# includedNamespaces: 列出要包括在备份中的命名空间。
|
||
# includedResources: 指定备份中要包括的资源类型。
|
||
# excludedResources: 指定不包括在备份中的资源类型。
|
||
schedules:
|
||
backup:
|
||
disabled: true
|
||
schedule: "*/1 * * * *"
|
||
useOwnerReferencesInBackup: false
|
||
template:
|
||
ttl: "240h"
|
||
storageLocation: default
|
||
includedNamespaces:
|
||
- default
|
||
includedResources:
|
||
- pv,pvc
|
||
excludedResources:
|
||
- pod
|
||
```
|
||
|
||
3. 安装
|
||
|
||
```bash
|
||
helm install velero vmware-tanzu/velero \
|
||
--namespace velero --create-namespace \
|
||
-f velero-values.yaml
|
||
```
|
||
|
||
4. 下载客户端
|
||
|
||
```bash
|
||
wget https://github.com/vmware-tanzu/velero/releases/download/v1.14.0/velero-v1.14.0-linux-amd64.tar.gz
|
||
```
|
||
|
||
5. 解压文件
|
||
|
||
```bash
|
||
tar -zxvf velero-v*-linux-amd64.tar.gz
|
||
```
|
||
|
||
6. 移动客户端二进制文件到可执行目录
|
||
|
||
```bash
|
||
mv velero-v*-linux-amd64/velero /usr/local/bin/
|
||
```
|
||
|
||
## 卸载
|
||
|
||
1. 卸载 velero
|
||
|
||
```bash
|
||
helm uninstall velero -n velero
|
||
```
|
||
|
||
2. 删除命名空间
|
||
|
||
```bash
|
||
kubectl delete ns velero
|
||
```
|
||
|
||
# 基础命令
|
||
|
||
- 查看所有备份
|
||
|
||
```bash
|
||
velero get backups
|
||
```
|
||
|
||
- 备份整个集群
|
||
|
||
```bash
|
||
velero backup create <backup-name>
|
||
```
|
||
|
||
**基础参数**
|
||
|
||
- 备份特定的命名空间 `--include-namespaces <namespace>`
|
||
- 备份特定的资源 `--include-resources <resources>`
|
||
- 备份多个特定的资源 `--include-resources pv,pvc`
|
||
- 排除特定资源 `--exclude-resources <resources>`
|
||
|
||
- 恢复整个备份
|
||
|
||
```
|
||
velero restore create --from-backup <backup-name>
|
||
```
|
||
|
||
- 恢复特定资源 `--include-resources <resources>`
|
||
|
||
- 恢复到特定命名空间 `--namespace-mappings old-namespace:<new-namespace>`
|
||
|
||
- 恢复时指定名称
|
||
|
||
> 这个名称有助于你后续追踪和管理这次特定的恢复操作
|
||
|
||
```bash
|
||
velero restore create <restore-name> --from-backup <backup-name>
|
||
```
|
||
|
||
- 删除备份
|
||
|
||
```bash
|
||
velero backup delete <backup-name>
|
||
```
|
||
|
||
> 删除操作时不想被提示确认，可以添加 `--confirm` 参数来直接删除
|
||
|
||
- 创建定时备份
|
||
|
||
> 使用 Cron 表达式(可用参数和 backup 一致)
|
||
|
||
```bash
|
||
velero schedule create <schedule-name> --schedule="* * * * *"
|
||
```
|
||
|
||
- 每 24 小时备份一次 `--schedule="@every 24h"`
|
||
- 每一分钟执行一次 `--schedule="1 * * * *"`
|
||
|
||
- 查看全部定时备份
|
||
|
||
```bash
|
||
velero get schedule
|
||
```
|
||
|
||
- 删除定时备份
|
||
|
||
```bash
|
||
velero schedule delete <schedule-name>
|
||
```
