使用 Docker 直接运行，打开项目后提示“No HEAD exists and no explicit starting revision was specifiedDISMISS”

[cnxiaoby]

使用 Docker 直接运行：

docker run -d --name webide -p 8080:8080 -v /docker/webide:/root/.coding-ide --restart=always webide/webide

添加好 SSH GIT 项目后，打开项目，没有代码文件树目录，并有红色提示框提示：

No HEAD exists and no explicit starting revision was specifiedDISMISS

WebDebug 发现仅有一个连接 500 错误：

看错误描述是打开了一个没有任何提交的空仓库项目。

可以在 WebTerminal 中输入 git log，查看是否有提交？
