本文探讨了DockerCompose如何通过YAML文件定义容器间的依赖关系，特别关注于Fabric网络环境中排序服务与Peer节点的配置。同时，文章列举了DockerCompose的常用命令，并分析了在Fabric操作中常见的权限不足错误。

Compose采用 YAML文件定义 Docker容器之间的依赖，设置环境变量和文件的持久化。我们看一个配置文件examples/e2e_cli/base/docker-compose-base.yaml的节选:

在这个节选的配置文件中，一共定义了 l 个排序服务节点 orderer.example.com 和 l 个 Peer节点 peerO.orgI.example.com。 Docker Compose 目前有 3个版本，这个配置文件采用的 version 2 的语法，配置文件的解释如表 2-2 所示

Docker Compose 的常用命令

Docker Compose 的常用命令如表 2-3 所示。

常见错误

1. 请求调用者权限不足

调用的时候设置了错误的 MSP，比如需要管理员才能执行创建通道的操作，但是设置了普通的成员 MSP，会出现 Error: Got unexpected status: BAD_REQUEST 的错误 :
