Docker 使用 GitBash / Cmder - 路径问题

Question

Docker 终端命令

\n尝试使用 docker 教程 [https://docs.docker.com/get-started/06_bind_mounts/][1]\n

docker run -dp 3000:3000 -w /app -v "$(pwd):/app" node:12-alpine sh -c "yarn install && yarn run dev"\n

\n

我对上面的代码行有疑问。我在 Cmder、GitBash 和 Windows 10 PowerShell 终端中运行此行。

\n

控制台 1 - Cmder - 错误：

\n

docker: Error response from daemon: create $(pwd): "$(pwd)" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intended to pass a host directory, use absolute path.\nSee \'docker run --help\'.\n

\n

控制台 2 - GitBash - `错误`：

\n

docker: Error response from daemon: the working directory \'C:/Program Files/Git/app\' is invalid, it needs to be an absolute path.\nSee \'docker run --help\'.\n

\n

以前有人让它在 GitBash 或 Cmder 中工作吗？或者这是我的 Env 问题？猜测大多数人会在 Mack 操作系统或 Linux 发行版上运行它。也许 vegrant + docker 是正确的选择？你在 Windows 上的设置是什么？

因此，针对上述问题，我修改了添加附加“/”的行（How to stop MinGW and MSYS from mangling path names Give at the command line）

现在我们有......错误Couldn\'t find a package.json file in "/app"有人能解决 gitbash 中的问题吗？

Answer 1

控制台 2 - GITBASH - 解决方案

根据如何阻止 MinGW 和 MSYS 从命令行给出的修改路径名，MSYS_NO_PATHCONV=1我们可以通过在实际命令之前运行来使其在 Git bash 上工作。这将禁用该命令的路径转换。还有一种方法可以全局关闭路径转换，但因为我不知道确切的后果，所以我选择在每个命令之前添加此位。

控制台 2 - GitBash - 确定

MSYS_NO_PATHCONV=1 docker run -dp 3000:3000 -w /app -v "$(pwd):/app" node:12-alpine sh -c "yarn install && yarn run dev"

控制台 1 - CMDER - 未找到 /app - 容器已创建但未运行

为了让这个命令在 cmndr 终端中工作，我必须在 `$(pwd)` 之前添加 `/`，如下所示：

docker run -dp 3000:3000 -w /app -v /$(pwd):/app node:12-alpine sh -c "yarn install && yarn run dev"

不幸的是，这并没有完全奏效。这次运行没有报错，但是没有找到/app路径下的文件。DOcker 容器已创建，但未显示在下面docker ps

error Couldn't find a package.json file in "/app"
