docker git clone public仓库时出错

Question

1. dockerfile 中 git clone 时，发现即便是public的仓库，也会出错

2. 下面是我用GIT_CURL_VERBOSE=1 输出git clone的日志

Step 12/16 : RUN GIT_CURL_VERBOSE=1 git clone https://github.com/aijm/BSplineSurface.git
 ---> Running in acb027444855

The command '/bin/sh -c GIT_CURL_VERBOSE=1 git clone https://github.com/aijm/BSplineSurface.git' returned a non-zero code: 128

在本机上，输出的结果是:

# 只把关键部分放上来
aijiaming@ubuntu:~$ GIT_CURL_VERBOSE=1 git clone https://github.com/aijm/BSplineSurface.git

看着好像是SSL的问题，这部分我没太接触过，不知道为啥前一个到ALPN, offering http/1.1 就断了。

3. 我尝试搜了很多，但大部分资料都是关于ssh配置访问private仓库的，没太看到和我这个类似的问题。

求大佬帮忙看看，我应该如何解决？
谢谢了

dockerfile 里加上

ADD ~/.ssh ~/.ssh
