Orderer 容器无法运行 Hyperledger Fabric 2.0

分类：编程问答

如何解决Orderer 容器无法运行 Hyperledger Fabric 2.0

我正在尝试在fabric-samples 中提供的“测试网络”之上创建我自己的网络。尽管测试网络运行良好，但当我对其进行更改（例如将 org1 和 org2 重命名为其他名称）时，所有内容都运行，但排序容器在几秒钟后停止运行，

我对 Fabric 非常陌生。我正在尝试为供应链建立一个包含 3 个组织的网络：制造商、供应商和零售商。如果有人能在这里指导我，他们的帮助将不胜感激。

我在 Ubuntu 18.04 上使用 Hyperledger Fabric 2.0。

解决方法

在@myeongkil kim 的帮助下，我解决了这个问题。解决方案是我只需要在 docker volume prune 之前删除所有 docker 卷，然后恢复网络即可解决此问题。
