Docker错误：没有这样的文件或目录，请打开'/包。带有NestJs应用程序的json

Question

我试图在docker内运行节点映像（使用nestJS应用程序），但出现以下错误：

我已经阅读了所有与这个主题相关的帖子。但是没有运气-

我的docker文件

# Download base image
FROM node:12.22.4-alpine As development

# Define Base Directory
WORKDIR /project/sawtooth-tuna/backend

# Copy and restore packages
COPY package*.json ./

RUN npm install --only=development

# Copy all other directories
COPY . .

# Setup base command
RUN npm run build

# # second phase
FROM node:12.22.4-alpine As production

# Declaring working directory
WORKDIR /project/sawtooth-tuna/backend

COPY package*.json ./

RUN npm install --only=production

#Copy build artifacts
COPY --from=builder /project/sawtooth-tuna/backend/dist ./
COPY --from=builder /project/sawtooth-tuna/backend/config ./config

# Start the server
CMD [ "node", "main.js" ]

因为我正在使用docker-compose-

 tunachain-backend:
    build:
      context: .
      target: development
      dockerfile: ./backend/Dockerfile
    image: hyperledger/tunachain-backend
    container_name: tunachain-backend
    volumes:
      - .:/project/sawtooth-tuna/backend
      - /project/sawtooth-tuna/backend/node_modules
    command: npm run start:dev
    ports:
      - 3001:3001
      - 9229:9229

我的项目结构-

    backend -
        NestJs application code
        Dockerfile
    docker-compose

• 任何建议或提示（我应该如何调试该问题）。docker还是个新手---

Answer 1

在这里，问题是，我如何以及在何处将我的包*. json复制到目标文件夹。由于我的docker compose文件在根目录中，而我的Dockerfile在backend文件夹中。复制命令应类似于backend/pack*. json./。

此外，用于调试问题。我刚刚找到我最后一个成功的步骤图像。并尝试在该图像中运行步骤（导致问题），以获得更多见解。

希望将来有人能从中得到一些帮助。
