我已经安装了minio和NFS存储，并在kubernetes集群上安装了velero。我在perm上有一个主节点和两个工作节点。两个pod（minio和velero）都在运行，没有错误。当我尝试Velero backup create testbackup --include-namespaces myns --wait时，备份失败。当我检查Velero日志进行testbackup时，我看到了此日志。

An error occurred: Get "http://minio.velero.svc:9000/velero/backups/test/test-logs.gz?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=minio%2F20230203%2Fminio%2Fs3%2Faws4_request&X-Amz-Date=20230203T110817Z&X-Amz-Expires=600&X-Amz-SignedHeaders=host&X-Amz-Signature=2d932b7717a857918337ffc26f08add6": dial tcp: lookup minio.velero.svc on 127.0.0.53:53: no such host

奇怪的是，Velero正在寻找的主机不是我的主机。
我正在学习this教程，但无法找到解决方案。我也尝试了Velero的官方文档来安装Minio，发现了同样的问题。

        volumeMounts:

          mountPath: "/config"

我就是这样安装Velero的

velero install \
    --provider aws \
    --plugins velero/velero-plugin-for-aws:v1.0.0 \
    --bucket velero \
    --secret-file ./credentials-velero \
    --use-volume-snapshots=false \
    --backup-location-config region=minio,s3ForcePathStyle="true",s3Url=http://minio.velero.svc:9000

我做了什么我尝试了不同的服务类型，并尝试在velero安装过程中添加minio服务IP。我想要什么我想要执行备份并找到Valero存储备份的位置。
