docker - Hyperledger锯齿安装问题。主机和Docker容器之间没有连接

Question

我是一名学生，试图通过linux基金会的hyperledger类(class)学习有关区块链的知识。我正在通过docker安装锯齿框架，但遇到了一些问题。我正在尝试运行以下命令来检查从主机到Docker容器的连接性:

curl http://localhost:8008/blocks

curl: (7) Failed to connect to localhost port 8008: Connection refused

有人可以帮助我打开此连接docker和主机吗？我在ubuntu上使用虚拟机，在此先多谢!

这是yaml文件:

您应该将端口从本地计算机传递到Docker容器。

尝试在运行容器时将-p 8008:8008作为参数传递

例如。 docker run -d -p 8008:8008 my_image
