FN Hello World应用程序8080连接问题

Question

我在这里学习Fn简介和Python教程。我在Mac Catalina 10.15.7上。

当我运行命令"；fn创建应用程序pythonapp"在我的终端中，我收到错误

Fn: Post "http://127.0.0.1:8080/v2/apps": dial tcp 127.0.0.1:8080: connect: connection refused

我试着在这里解释解决方案，但没有解决问题。

当我跑"；fn版本"；这是我的输出。

Client version is latest version: 0.6.1
Server version:  ?

如果我运行"；fn启动"；这是我的输出。

Answer 1

1. 确保Docker守护进程(Docker桌面(正在运行
2. 在一个终端中运行"fn start"。这将在localhost中启动fn服务器。您可以使用"fn list contexts"命令进行验证
3. 打开第二个终端并运行"fn版本"。它应该同时显示客户端和服务器版本

如果服务器版本丢失，则意味着您的fn服务器仍然没有运行，您将无法部署和调用您的函数。
