在GKE集群中部署erigon主网归档节点

Question

我目前正在尝试将带有erigon docker映像的主网归档节点部署到GKE集群(thorax/erigon)。我已经成功地部署了一个具有如下类似配置的Geth节点，但是当我试图在erigon上使用相同的方法时，我没有成功。

下面是我的YAML部署文件:

从kubectl describe pod得到的结果:

因此，我的假设是我可能将SSD挂载到错误的目录。我已经尝试将--datadir标志留空并将其挂载到默认的datadirerigon目录，但我仍然遇到崩溃循环。对于我的Geth节点，我将与上面完全相同的逻辑挂载到/chaindata，节点运行良好。如果有人知道这里的问题可能是什么，任何帮助都是感激的。我是GKE的新手，所以这可能是我忽略的一个简单的解决方案。

失败:

exec: "--datadir=/mainnet"
: stat --datadir=/mainnet: no such file or directory

和erigon文档读:

使用--datadir来选择存储数据的位置

你可以用任何你想用的，但是目录/卷必须存在，这样stat /mainnet命令才不会失败。我假定您没有创建gcepersistentdisk来挂载:
https://cloud.google.com/sdk/gcloud/reference/compute/disks/create

gcloud compute disks create --size=1TB --zone=us-central1-a mainnet-data

然后声明为PD，持久磁盘:

gcePersistentDisk:
pdName: mainnet-data
fsType: ext4

ConfigvolumeClaimTemplates表示kind: StatefulSet;使用kind: Deployment。这个例子也使用Deployment的一切;它可以将整个区块链下载到--datadir.
当您查看以太坊链完全同步数据大小时，这意味着--size=1TB或2TB:

相比之下，expedition只使用以太坊EPC端点。
