本节包含 Backup 和 Restore 自定义资源的示例。

默认的备份存储位置是在安装或升级rancher-backup operator 时配置的。

只有 Restore 自定义资源使用与创建备份相同的加密配置 secret 时，才能还原加密的备份。

备份

本节包含 Backup 自定义资源的示例。

在默认位置进行加密备份

apiVersion: resources.cattle.io/v1
kind: Backup
metadata:
  name: default-location-encrypted-backup
spec:
  resourceSetName: rancher-resource-set
  encryptionConfigSecretName: encryptionconfig

在默认位置进行定期备份

apiVersion: resources.cattle.io/v1
kind: Backup
metadata:
  name: default-location-recurring-backup
spec:
  resourceSetName: rancher-resource-set
  schedule: "@every 1h"
  retentionCount: 10

在默认位置进行加密的定期备份

apiVersion: resources.cattle.io/v1
kind: Backup
metadata:
  name: default-enc-recurring-backup
spec:
  resourceSetName: rancher-resource-set
  encryptionConfigSecretName: encryptionconfig
  schedule: "@every 1h"
  retentionCount: 3

Minio 中的加密备份

apiVersion: resources.cattle.io/v1
kind: Backup
metadata:
  name: minio-backup
spec:
  storageLocation:
    s3:
      credentialSecretName: minio-creds
      credentialSecretNamespace: default
      bucketName: rancherbackups
      endpoint: minio.sslip.io
      endpointCA: LS0tLS1CRUdJTi3VUFNQkl5UUT.....pbEpWaVzNkRS0tLS0t
  resourceSetName: rancher-resource-set
  encryptionConfigSecretName: encryptionconfig

使用 AWS Credential Secret 在 S3 中备份

apiVersion: resources.cattle.io/v1
kind: Backup
metadata:
  name: s3-backup
spec:
  storageLocation:
    s3:
      credentialSecretName: s3-creds
      credentialSecretNamespace: default
      bucketName: rancher-backups
      folder: ecm1
      region: us-west-2
      endpoint: s3.us-west-2.amazonaws.com
  resourceSetName: rancher-resource-set
  encryptionConfigSecretName: encryptionconfig

使用 AWS Credential Secret 在 S3 中进行定期备份

apiVersion: resources.cattle.io/v1
kind: Backup
metadata:
  name: s3-recurring-backup
spec:
  storageLocation:
    s3:
      credentialSecretName: s3-creds
      credentialSecretNamespace: default
      bucketName: rancher-backups
      folder: ecm1
      region: us-west-2
      endpoint: s3.us-west-2.amazonaws.com
  resourceSetName: rancher-resource-set
  encryptionConfigSecretName: encryptionconfig
  schedule: "@every 1h"
  retentionCount: 10

从具有访问 S3 的 IAM 权限的 EC2 节点进行备份

这个例子表明，如果运行 rancher-backup 的节点拥有这些访问 S3 的权限，就不必提供 AWS 的凭证 secret 来创建备份。

apiVersion: resources.cattle.io/v1
kind: Backup
metadata:
  name: s3-iam-backup
spec:
  storageLocation:
    s3:
      bucketName: rancher-backups
      folder: ecm1
      region: us-west-2
      endpoint: s3.us-west-2.amazonaws.com
  resourceSetName: rancher-resource-set
  encryptionConfigSecretName: encryptionconfig

恢复

本节包含 Restore 自定义资源的示例。

使用默认备份文件位置还原

apiVersion: resources.cattle.io/v1
kind: Restore
metadata:
  name: restore-default
spec:
  backupFilename: default-location-recurring-backup-752ecd87-d958-4d20-8350-072f8d090045-2020-09-26T12-29-54-07-00.tar.gz
#  encryptionConfigSecretName: test-encryptionconfig

恢复 Rancher 迁移

apiVersion: resources.cattle.io/v1
kind: Restore
metadata:
  name: restore-migration
spec:
  backupFilename: backup-b0450532-cee1-4aa1-a881-f5f48a007b1c-2020-09-15T07-27-09Z.tar.gz
  prune: false
  storageLocation:
    s3:
      credentialSecretName: s3-creds
      credentialSecretNamespace: default
      bucketName: rancher-backups
      folder: ecm1
      region: us-west-2
      endpoint: s3.us-west-2.amazonaws.com

从加密的备份中恢复

apiVersion: resources.cattle.io/v1
kind: Restore
metadata:
  name: restore-encrypted
spec:
  backupFilename: default-test-s3-def-backup-c583d8f2-6daf-4648-8ead-ed826c591471-2020-08-24T20-47-05Z.tar.gz
  encryptionConfigSecretName: encryptionconfig

从 Minio 恢复加密的备份

apiVersion: resources.cattle.io/v1
kind: Restore
metadata:
  name: restore-minio
spec:
  backupFilename: default-minio-backup-demo-aa5c04b7-4dba-4c48-9ac4-ab7916812eaa-2020-08-30T13-18-17-07-00.tar.gz
  storageLocation:
    s3:
      credentialSecretName: minio-creds
      credentialSecretNamespace: default
      bucketName: rancherbackups
      endpoint: minio.sslip.io
      endpointCA: LS0tLS1CRUdJTi3VUFNQkl5UUT.....pbEpWaVzNkRS0tLS0t
  encryptionConfigSecretName: test-encryptionconfig

使用 AWS 凭证 Secre 访问 S3 从备份中还原

apiVersion: resources.cattle.io/v1
kind: Restore
metadata:
  name: restore-s3-demo
spec:
  backupFilename: test-s3-recurring-backup-752ecd87-d958-4d20-8350-072f8d090045-2020-09-26T12-49-34-07-00.tar.gz.enc
  storageLocation:
    s3:
      credentialSecretName: s3-creds
      credentialSecretNamespace: default
      bucketName: rancher-backups
      folder: ecm1
      region: us-west-2
      endpoint: s3.us-west-2.amazonaws.com
  encryptionConfigSecretName: test-encryptionconfig

从具有 IAM 权限的 EC2 节点还原以访问 S3

这个例子表明，如果运行 rancher-backup 的节点拥有这些访问 S3 的权限，就不必提供 AWS 的凭证 secret 来从备份中还原。

apiVersion: resources.cattle.io/v1
kind: Restore
metadata:
  name: restore-s3-demo
spec:
  backupFilename: default-test-s3-recurring-backup-84bf8dd8-0ef3-4240-8ad1-fc7ec308e216-2020-08-24T10#52#44-07#00.tar.gz
  storageLocation:
    s3:
      bucketName: rajashree-backup-test
      folder: ecm1
      region: us-west-2
      endpoint: s3.us-west-2.amazonaws.com
  encryptionConfigSecretName: test-encryptionconfig

在 S3 中存储备份的凭证 Secret 示例

apiVersion: v1
kind: Secret
metadata:
  name: creds
type: Opaque
data:
  accessKey: <Enter your base64-encoded access key>
  secretKey: <Enter your base64-encoded secret key>
