Question

我有一个定义5个服务的docker-compose.yaml文件：

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

命令导致：

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

我如何确定容器名称为何已经使用？

Answer 1

根据您提供的错误：

错误：for orderer.example.com无法为服务orderer.example.com创建容器：冲突。容器名称＆＃34; /orderer.example.com"已被容器使用＆＃34; d6621116cf0d1ab108277893178ba29a创建peer0.org1.example.com ...错误

错误：对于peer0.org1.example.com无法为服务peer0.org1.example.com创建容器：冲突。容器名称＆＃34; /peer0.org1.example.com"已被容器使用＆＃34; 185c6449d163fa5593001b3创建peer0.org2.example.com ...已完成

错误：对于peer0.org1.example.com无法为服务peer0.org1.example.com创建容器：冲突。容器名称＆＃34; /peer0.org1.example.com"已被容器使用   ＆＃34; 185c6449d163fa5593001b3bf9e052eee9ea365f89564a31fd84aac3c828bfbd＆＃34 ;.您必须删除（或重命名）该容器才能重用该名称。

错误：for orderer.example.com无法为服务orderer.example.com创建容器：冲突。容器名称＆＃34; /orderer.example.com"已被容器使用＆＃34; d6621116cf0d1ab108277893178ba29a05d4e50b36143d33fb6ec1dfc472eeb8＆＃34;。您必须删除（或重命名）该容器才能重用该名称。

错误：启动项目时遇到错误

我假设你已经停止了从之前的执行/试验中删除/清理过的容器，因此启动具有相同名称的新容器会导致上述错误。你能不能试试

docker ps -a

检查是否有容器名称为peer0.org1.example.com，peer0.org1.example.com等等？

无论如何，您可以尝试运行

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的列表。一张一张地删除它们：

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

无法为超级链接服务创建容器
