任何人都可以帮助我如何在超级账本网络重启之间保留数据,以免丢失数据。我已经看到有关持久化卷的帖子,但是我不确定如何利用该功能。在Fabcar演示中,我存储了Cars的数据。如果我重新启动网络,我不想丢失Car数据,以便下次查询是否应将旧数据存储在beddb中时使用。我真的很想知道我们如何进行数据持久化。

根据documentation here,您需要做的就是更改docker compose文件,以便ouchDB使用主机目录来装载其数据。
对于文件中的对等部分,添加以下两行:
volumes:
- /var/hyperledger/peer0:/var/hyperledger/production
对于Couchdb部分,添加:
volumes:
- /var/hyperledger/couchdb0:/opt/couchdb/data
现在使用更新的docker compose文件启动网络。
