无法为超级账本服务创建容器

Question

我有一个 docker-compose.yaml 文件定义了 5 个服务：

orderer.example.com
peer0.org1.example.com
peer1.org1.example.com
peer0.org2.example.com
peer1.org2.example.com

运行

docker-compose -f docker-compose.yaml up -d

命令结果：

Creating network "hlf_byfn" with the default driver

Creating peer0.org2.example.com ...

Creating orderer.example.com ...

Creating peer0.org2.example.com

所以无法创建orderer.example.com和peer0.org1.example.com。 docker ps 的输出：

我如何确定哪里出了问题，为什么容器名称已被使用？

Answer 1

根据您提供的错误：

ERROR: for orderer.example.com Cannot create container for service orderer.example.com: Conflict. The container name "/orderer.example.com" is already in use by container "d6621116cf0d1ab108277893178ba29aCreating peer0.org1.example.com ... error

ERROR: for peer0.org1.example.com Cannot create container for service peer0.org1.example.com: Conflict. The container name "/peer0.org1.example.com" is already in use by container "185c6449d163fa5593001b3Creating peer0.org2.example.com ... done

ERROR: for peer0.org1.example.com Cannot create container for service peer0.org1.example.com: Conflict.

You have to remove (or rename) that container to be able to reuse that name.

我假设您已经停止了与之前的 executions/trials 相比 removed/cleaned 更高的容器，因此启动具有相同名称的新容器会导致上述错误。你能试试运行

docker ps -a

检查是否有容器名称：peer0.org1.example.com、peer0.org1.example.com 等等...?

无论如何你都可以尝试运行

docker ps -qa | xargs docker rm

然后再次尝试启动您的网络：

docker-compose -f docker-compose.yaml up -d

Answer 2

您需要停止容器

docker ps -qa | xargs docker stop

Answer 3

该示例适用于存储库的 FirstNetwork 示例：

这对我有用：清理环境：

docker ps -aq

^ 这将为您提供容器 ID 列表。将它们一一删除：

docker rm -rf containerIds

执行向下命令：

./byfn.sh -m down

然后执行向上命令：

./byfn.sh -m up
