我正在使用超级账本结构 V1.4 中提供的byfn 网络编写链代码应用程序。当我添加或删除一些代码时，我关闭了 byfn 网络并删除了 docker 容器，然后重新启动了 byfn 网络，使用与以前相同的名称和版本来安装和实例化代码。我发现如果使用与以前相同的版本，更改的代码并不费力。
我认为这与我预期的不一样，因为我关闭了网络并删除了容器。我使用 docker volume ls 和 inspect 命令，发现 net_peer0.org1.example.com 下的文件在 byfn 网络关闭时被清除，因此没有现有的以前版本的代码。我想知道为什么更改后的代码不费力，以及为什么在我升级到以前未使用过的新版本后它可以工作。
docker compose 文件和 byfn 教程提供的一样：

是 hyperledger fabric 1.4 的特性还是我的操作有问题？目前我通过在代码中添加输出并在 dev_peer.org.example.com 容器中查看它们进行调试，有没有更好的方法在超级账本中开发链代码？
更新
我在 cli 容器中的 peer0.org1 和 peer0.org2 中安装了名为 master 的链代码，版本为 1.0。我从 cli 容器中实例化了 peer0.org2 中的 master。我使用docker logs peerX.orgX.example.com命令来获取每个对等容器的日志。
日志如下：
