无法连接 尝试连接到本地对等方时出错：已超出上下文截止时间

Question

我正在尝试实例化多个对等方之间的链码，每个对等方都在各自的组织中。出于调试目的，我创建了一个通道testchannel，只有一个组织overseer只有一个对等peer0。我能够

• 创建频道
• 加入频道(当我使用peer channel list时，频道出现在结果中(
• 安装链码(当我使用peer chaincode list --installed时，链码出现在结果中(

但是当我使用peer chaincode instantiate -C testchannel -v v0 -n example --peerAddresses peer0.overseer.bloomberg.com:7051 -o orderer.bloomberg.com:7050 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('OverseerOrg.peer')"实例化链码时，一个新的链码容器被启动，但在几秒钟后退出，因为它无法到达对等体。

我已经确保当我实例化链码时，我设置了环境变量CORE_PEER_ADDRESS=peer0.overseer.example.com:7051

链码容器的日志为：

这是我的docker-compose.yaml设置：

peer0.overseer.example.com:
container_name: peer0.overseer.example.com
extends:
file: ./configs/base.yaml
service: peer-base
environment:
- CORE_LOGGING_LEVEL=DEBUG

这是我用于创建频道的configtx.yaml

当我在对等容器中运行docker exec -it peer0.overseer.example.com bash并运行netstat --all时，我的结果是：

如何解决此问题或进一步调试问题所在？谢谢。

Answer 1

问题是因为我在我的base.yaml文件中，我将环境变量CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE设置为过时但仍然存在的 docker 网络(在我的情况下是artifacts_default(，这就是为什么它没有在链码实例化中抛出"网络不存在"错误。当我启动 docker 容器时，它加入了从撰写文件所在的目录派生的默认网络，该网络与CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE环境变量设置的网络名称不匹配。
