Question

我无法从Dockerfile编译nodejs打字稿应用程序。当我构建docker映像时，检查它完全丢失了dist文件夹。

Dockerfile：

# Template: Node.js dockerfile
# Description: Include this file in the root of the application to build a docker image.

# Enter which node build should be used. E.g.: node:argon 
FROM node:latest

# Create app directory for the docker image
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app/dist

# Install app dependencies from package.json. If modules are not included in the package.json file enter a RUN command. E.g. RUN npm install <module-name>
COPY package.json /usr/src/app/
RUN     npm install
RUN     npm install tsc -g
RUN     tsc

# Bundle app source
COPY . /usr/src/app

# Enter the command which should be used when the image starts up. E.g. CMD ["node", "app.js"]
CMD [ "node", "server.js"]

当我在本地运行映像并通过ls显示文件/文件夹时：

# ls
node_modules  package-lock.json  package.json  src

关于我要去哪里的任何建议吗？

据我所知
WORKDIR不必自己创建。这是documentation for WORKDIR。

之后，您无需手动复制到特定文件夹，因为在执行WORKDIR命令之后，复制命令将为您复制文件。

因此，我建议您使用以下Dockerfile：

    FROM node:alpine
    WORKDIR /usr/yourapplication-name
    COPY package.json .
    RUN npm install\
        && npm install tsc -g
    COPY . .
    RUN tsc
    CMD ["node", "./dist/server.js"]

一个小技巧：我将package.json中的打字稿用作依赖项，然后仅使用以下文件：

    FROM node:alpine
    WORKDIR /usr/yourapplication-name
    COPY package.json .
    RUN npm install
    COPY . .
    RUN tsc
    CMD ["node", "./dist/server.js"]
