Node.js 如何在Dockerfile中编译typescript

从Dockerfile编译nodejs typescript应用程序时遇到问题。当我构建docker映像时，它完全缺少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"]

    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"]

对我的错误有什么建议吗？

据我所知，

WORKDIR

不必自己创建。 这是你的建议。

之后，您不必手动复制到特定文件夹， 因为在

WORKDIR

命令之后，copy命令将为您复制文件

因此，我建议您使用以下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"]

    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"]

作为一个小技巧：我会在我的

package.json

中使用typescript作为依赖项，然后只使用以下文件：

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

我可以看到几个问题：1。您可以将mkdir/usr/src/app和WORKDIR添加到不存在的子目录。2.在复制文件之前运行tsc，后者返回：

/bin/sh:1:tsc:notfound

@DerkJanSpeelman:因为该类型脚本必须是项目的依赖项（如我在回答中所述）。然后npm安装将为您的项目安装所有依赖项，并将找到命令tsc。我想在这个聊天室中进一步讨论我的问题：，如果您能抽出时间帮助我，我将不胜感激！
