My development Dockerfile is set up as follows:
FROM node:18-alpine
WORKDIR /app
# Installing dependencies based on the preferred package manager
COPY package.json yarn.lock* package-lock.json* pnpm-lock.yaml* ./
RUN \
if [ -f yarn.lock ]; then yarn --frozen-lockfile; \
elif [ -f package-lock.json ]; then npm ci; \
elif [ -f pnpm-lock.yaml ]; then yarn global add pnpm && pnpm i; \
else echo "Warning: Lockfile not found. It is recommended to commit lockfiles to version control." && yarn install; \
fi
COPY .
# Starting Next.js in development mode using the preferred package manager
CMD \
if [ -f yarn.lock ]; then yarn dev; \
elif [ -f package-lock.json ]; then npm run dev; \
elif [ -f pnpm-lock.yaml ]; then pnpm dev; \
else yarn dev; \
fi
In addition, here is my docker-compose.yml configuration:
services:
docker-prod:
container_name: docker-prod
build:
context: .
dockerfile: dev.Dockerfile
ports:
- "3000:3000"
volumes:
- .:/app
After running docker-compose up, I encountered the following error:
docker-prod | Error: Cannot find module '/app/node_modules/next/dist/bin/next'
docker-prod | at Module._resolveFilename (node:internal/modules/cjs/loader:1075:15)
docker-prod | at Module._load (node:internal/modules/cjs/loader:920:27)

docker-prod | requireStack: []
docker-prod | }
I have attempted various path changes and adjustments to the COPY command. What could potentially be wrong with my Dockerfile setup?
