Hyperledger Explorer 未同步 HLF-fabric 交易

Question

我已经创建了 Kubernetes 集群。

配置：4 CPU X 16 GB 内存

在上面的 Kubernetes 集群上，我使用 Hyperledger Explorer（作为 pod）部署了一个超级账本区块链网络。区块链网络运行良好。 Hyperledger Explorer 也在工作，但仅在几个小时后才停止，既不显示错误也不显示警告，并且 Pod 也处于“运行”状态。但不同步区块链交易数据。

我创建了两个 pod，一个用于 explorer，一个用于 explorer-DB。我检查了 explorer-db pod 的日志并得到以下行

我通过 Kubernetes 边车模式找到了上述问题的解决方案。因此，每当我的主容器由于某些内存问题而重新启动时，它的边车容器也会自动重新启动。
