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

配置 velero 认证环境

mkdir /data/velero -p
cd /data/velero
cat velero-auth.txt
[default]
aws_access_key_id = admin
aws_secret_access_key = minio123

将 velero 安装到 K8s 集群

kubectl create ns velero-system

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

kubectl get pod -A

测试备份功能
