将erigon mainnet存档节点部署到GKE集群
我目前正在尝试将带有erigon停靠映像的mainnet存档节点部署到GKE集群(thorax/erigon)。我已经成功地部署了一个具有类似配置的Geth节点，但当尝试对erigon使用相同的方法时，我没有成功。
下面是我的YAML部署文件：

它失败了，因为：
exec: "--datadir=/mainnet"
: stat --datadir=/mainnet: no such file or directoryerigon文档内容如下：
使用
--datadir选择存储数据的位置。
因此，您可以任意使用，但是目录/卷必须存在，这样命令stat /mainnet就不会失败。我假设您还没有创建一个要挂载的gcepersistentdisk：
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: ext4Config volumeClaimTemplates的意思是kind: StatefulSet；使用kind: Deployment。这个示例还对所有东西都使用Deployment；它可以将整个区块链下载到--datadir中。
当您查看Ethereum链全同步数据大小时，这意味着--size=1TB或2TB

与之相比，expedition只使用Ethereum端点。
