构建Docker映像时如何解决JFrog配置读取错误-[错误]打开/root/.jfrog/jfrog-cli.conf：只读文件系统

Question

我正在构建docker映像并收到错误：

 => ERROR [14/36] RUN --mount=type=secret,id=jfrog-cfg,target=/root/.jfrog/jfrog-cli.conf     jfrog rt dl --flat artifact  0.7s
------

我用来构建docker镜像的命令是 DOCKER_BUILDKIT=1 docker build -t imagename . --secret id=jfrog-cfg,src=${HOME}/.jfrog/jfrog-cli.conf（jfrog配置位于${HOME}/.jfrog/jfrog-cli.conf）

JFrog正在运行，我正在下载的工件存在，因为我可以在不使用docker的情况下手动下载它。

在Linux上，docker使用root用户运行，因此${HOME}是/root而不是/home/your-user-name或您通常的主文件夹是什么。尝试使用显式完整路径名而不是env变量。
