Docker错误：没有这样的文件或目录，使用NestJs应用程序打开'/package.json'

Question

我试图在docker内运行一个节点图像(与nestJS应用程序)，但我有这个错误:

我已经阅读了所有与这个主题相关的帖子。但运气不好-

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" ]

当我使用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

• 任何建议或任何提示(我应该如何调试这个问题)。docker -

Answer 1

这里的问题是，我如何以及在哪里复制我的包*。Json到目标文件夹。因为我的docker compose文件在根目录下，我的Dockerfile在backend文件夹下。复制命令看起来应该像backend/package*.json ./。

也用于调试问题。我刚刚找到了我最后一张成功的照片。和sh进入它，并试图在该图像中运行步骤(导致问题)，以获得更多的见解。

希望将来有人能从中得到一些帮助。
