我正在尝试使用Dockerfile为节点打字稿项目创建生产构建。
尽管，在将TS文件转换为Javascript的步骤中，出现以下错误：
error TS5057: Cannot find a tsconfig.json file at the specified directory: '.'.
error Command failed with exit code 1.
有人可以帮我解决这个问题吗？
以下是有关所使用的主要文件的信息：
FROM node:lts-stretch-slim
# Create app directory to hold the application code inside the image
WORKDIR /usr/src/app
# Install app dependencies
COPY package*.json yarn.lock ./

PS：Dockerfile和tsconfig.json都位于项目的根目录（我指的是同一级别）。而且我可以在本地（在Dockerfile外部）成功运行yarn build脚本，这反过来仅使用JS代码生成dist文件夹。
PS2：我遵循this tutorial以便为我构建一个类似的Dockerfile。

您没有将所有文件复制到容器中。您只复制其中的内容
带有COPY ./dist .
我对您的问题是，这是用于开发还是用于生产？ 如果用于开发，则可以使用
复制项目的while根目录COPY . .
现在，如果这是用于生产构建，则肯定需要一个中间构建步骤，因此您只需要将已编译的JS代码复制到容器中并运行它。

感谢提供帮助的人们，我能够根据自己的需要调整Dockerfile。
我必须在tsconfig.json文件旁边创建一个空TS文件，以消除上面我的评论中提到的错误。我还必须删除脚本部分路径前面的dist，否则会出现module not found错误。
Dockerfile现在最终像这样：
FROM node:lts-stretch-slim
# FROM node:10
# Create app directory to hold the application code inside the image
WORKDIR /usr/src/app
# Install app dependencies
COPY package*.json yarn.lock ./
COPY tsconfig.json ./
COPY .env ./
COPY emptyTs.ts ./
RUN yarn
RUN yarn build
COPY ./dist .
# COPY . .
EXPOSE 3333
COPY entrypoint.sh /
ENTRYPOINT [ "/bin/bash", "/entrypoint.sh" ]
"scripts": {
"dev": "ts-node-dev --transpileOnly --ignore-watch node_modules src/server.ts",
"start": "node src/server.js",
"build": "tsc -p ."
},
我最终为此使用了多阶段构建。在下面，您可以找到我编写的Dockerfile脚本：
FROM node:lts-stretch-slim AS build
WORKDIR /usr/src/app
COPY package*.json yarn.lock ./
COPY tsconfig.json ./
COPY .env ./
RUN yarn
COPY . .
RUN yarn build
FROM node:lts-stretch-slim
WORKDIR /usr/src/app
COPY package*.json yarn.lock ./
COPY .env ./
RUN yarn
COPY --from=build /usr/src/app/dist ./
EXPOSE 3333
COPY entrypoint.sh /
ENTRYPOINT [ "/bin/bash", "/entrypoint.sh" ]
