I’m trying to deploy my app on VPS :

When I execute the command

docker compose -f docker-compose.production.yml --env-file .env.production up --build

I have an error message :

server-1  | > [email protected] start:prod
server-1  | > node build/index.js
server-1  |
server-1  | node:internal/modules/cjs/loader:1146
server-1  |   throw err;
server-1  |   ^

It tries to start from app/build/index.js but when it builds the app I specified app/build/src/index.js.

Here is my Dockerfile.production :

FROM node:lts-alpine

RUN apk --no-cache add curl
RUN apk add make g++ python3 git
RUN npm i -g node-pre-gyp

RUN mkdir /app
WORKDIR /app

COPY package*.json ./
RUN npm i -g

COPY .env ./.env
COPY src ./src
COPY tsconfig.json ./

RUN ["npm", "run", "build"]

CMD ["npm","run","start:prod"]

And this is my scrip in package.json :

  "scripts": {
    "start": "ts-node-dev src/index.ts",
    "build": "tsc",
    "start:prod": "node build/src/index.js",
    "seed": "ts-node-dev seed.ts"
  },

When I build locally this is the result :

Thanks a lot if anyone has a clue or can help.

Docker can’t file the index.js file in the build file. Try to change the script in package.json to :

"start:prod": "node build/index.js", but same issue.
