我今天刚刚下载了适用于Windows 10 64bit的Docker Toolbox.我正在阅读教程.尝试使用Dockerfile构建映像时,我收到以下错误.
脚步:
错误:$ docker build -t docker-whale.无法准备上下文:无法评估Dockerfile路径中的符号链接:GetFileAttributesEx C:\ Users\Villanueva\Test\testdocker\Dockerfile:系统找不到指定的文件.
顺便说一句:我试过几个选项@ https://github.com/docker/docker/issues/14339

通过docker-compose.yml我能够运行该应用程序.现在我们要将应用程序移动到生产环境,但我们不想使用容器数据库.那么有什么方法可以将我的本地MySQL数据库与应用程序连接使用docker-compose？
我的docker-compose.yml看起来像:
version: '3'
services:
web-app:
build:
context: .
dockerfile: web-app/Dockerfile
ports:
- 8080:8080
links:
- app-db
app-db:
build:
context: .
dockerfile: app-db/Dockerfile
environment:
- MYSQL_ROOT_PASSWORD=password
- MYSQL_DATABASE=Optimize
ports:
- 3306:3306
而不是app-db部分我只想连接到我的本地托管mysql数据库.
直到几天前，它Dockerfile都工作正常，当我今天尝试再次构建它时，它在终端中给出以下错误。我尝试使用多个 docker 基础映像，但仍然给出相同的错误。谁能帮我这个？我不认为我错过了什么。如果我错过了，它应该早先给我错误，但为什么现在呢？

但是，Dockerfile当我们使用Visual Studio构建它并开始运行而没有任何错误时，同样可以正常工作。
Docker文件如下所示：

RUN …我正在浏览一些链接以在 azure 应用程序服务上部署 React Js 应用程序。但是我在部署应用程序时遇到了一些问题。
我已经添加了所有必要的东西，比如web.config文件到public文件夹，并将构建目录添加到工作区。
使用 Visual Studio Code 将 Node.js 部署到 Azure 应用服务
遵循所有步骤，但当我尝试在 azure 应用服务上部署时出现以下错误。在部署之前，我会运行这些命令
npm run build.
