概念​

概念这篇文档介绍Pelicon内部使用或创造的概念,及其解释.

软件架构​

软件架构这篇文档简单介绍Pelicon的软件架构.

安装​

  1. Clone repo
git clone https://gitlab.daocloud.cn/ndx/engineering/storage/uds.git && cd uds
  1. 安装
kubectl apply -f deploy/crds
kubectl apply -f deploy
  1. 创建[StorageProvider](/cn/docs/concept#StorageProvider CRD)接入支持的存储系统(支持列表)
ls deploy/sp

kubectl apply -f xxx.yaml

或接入暂不支持的存储

使用​

  1. 自动扩容

  2. 定时快照

  3. 备份

自动扩容​

  1. 创建自动扩容Policy
apiVersion: uds.dce.daocloud.io/v1alpha1
kind: ResizePolicy
metadata:
  name: resize-when-reach-50percent
  namespace: default
spec:
  expansionCapacityBytes: 1073741824
  resizePolicyName: resize1
  threshold: 50
  1. PVC绑定Policy
kubectl annotate pvc <your-pvc-name> uds.dce.daocloud.io/policy-pvc='{"resizePolicies":{"resize-when-reach-50percens":null}}'

定时快照​

  1. 创建快照Policy
apiVersion: uds.dce.daocloud.io/v1alpha1
kind: SnapshotPolicy
metadata:
  name: scheduled-snap-01
  namespace: default
spec:
  retain: 10
  schedule: 0 42 14 * * 6
  1. PVC绑定Policy
kubectl annotate pvc <your-pvc-name> uds.dce.daocloud.io/policy-pvc='{"snapshotPolicies":{"scheduled-snap-01":null}}'

备份​

备份端配置​

  1. 备份到NFS
apiVersion: v1
kind: ConfigMap
metadata:
  labels:
    backend-storage-type: NFS
  name: nfs-target
  namespace: default
data:
  nfs.config: '{"nfsServer":"10.6.234.2","nfsExportPath":"/nfs","nfsBackupRootDir":"/backup"}'
  1. 备份到S3
apiVersion: v1
kind: ConfigMap
metadata:
  annotations:
    uds.dce.daocloud.io/backup-target-config: '{"s3ConfName":"dce-uds-backup-remote-s3","s3BackupBucket":"uds-backup"}'
  name: s3-target
  namespace: default
data:
  rclone.conf: |-
    [dce-uds-backup-remote-s3]
    type = s3
    provider = Minio
    env_auth = false
    access_key_id = Access KEY
    secret_access_key = Secret KEY
    endpoint = 10.7.209.49:9000
    location-constraint = us-east-1
    acl = private

创建自动备份policy​

apiVersion: uds.dce.daocloud.io/v1alpha1
kind: BackupPolicy
metadata:
  name: backup01
  namespace: default
spec:
  backupTargetType: S3
  backupType: full
  configMapName: s3-target
  configMapNamespace: default
  retain: 10
  schedule: 0 36 14 * * 5
status:
  phase: Running

PVC绑定Policy​

kubectl annotate pvc <your-pvc-name> uds.dce.daocloud.io/policy-pvc='{"backupPolicies":{"backup01":null}}'
