c - 如何在执行chaincode的docker中添加额外的C语言库编程环境？

Question

我想使用基于配对的加密库，但我的链代码中没有 Go 语言版本。

我已经运行了官方示例“e2e_cli”。使用命令“docker ps”，我们可以看到九个docker。

我认为名为“dev-peer0.org1.example.com-mycc-1.0”的 docker 是在节点“peer0.org1”中执行链代码的地方。

所以我需要向 Docker 添加 pbc 库编程环境，例如“dev-peer0.org1.example.com-mycc-1.0”。

但是“dev-peer0.org1.example.com-mycc-1.0”是在安装和实例化链代码时自动创建的，我找不到添加库的方法。我没有找到像“这样的卷路径”卷:'文件'docker-compose-cli.yaml'中的设置。

这是我在链代码中使用 PBC 库的部分。

Answer 1

我重新编译了镜像--hyperledger/fabric-ccenv:x86_64-1.0.0，添加了我需要的库。因为链码是在基于fabric-ccenv镜像运行的容器中编译的。
