I have the same issue
Next 14.2.3

.next folder in docker only includes these files and folders

cache
prerender-manifest.js
package.json
routes-manifest.json

[devhik0]

I can't see what it includes cuz it's crashing due to that build error above.

[tpdewolf]

@devhik0 You can ssh into the image by running docker run --rm -it myimage:latest sh (replace myimage:latest with your tag)

I do notice that it does work when I build the image in Github actions on ubuntu latest. When i'm building it on Mac m1 with --platform=linux/amd64 it doesnt create all files in .next

[devhik0]

@tpdewolf Yes, but it's giving same error when I run container and stopping. Weird one, same app is running in GitHub actions machine on Ubuntu, but crashing on Windows. I tried building locally via Dockerfile, but when I run it crashed again cuz of same error.

hey,
almost the same for me:

• I use Next.js 14.2.3.
• The docker image run correctly on my local env but it gets stuck when i run the image on a ubuntu server.
• I build my image FROM node:20-slim

[devhik0]

So, update: Check your Dockerfile and other files to make sure its copying all files and have right permissions.
Here i ll share what i changed and how it fixed everything.

# use the official Bun image
# see all versions at https://hub.docker.com/r/oven/bun/tags
FROM oven/bun:1 as base
WORKDIR /app

# install dependencies into temp directory
# this will cache them and speed up future builds
FROM base AS install
RUN mkdir -p /temp/dev
COPY package.json bun.lockb /temp/dev/
RUN cd /temp/dev && bun install

# install with --production (exclude devDependencies)
RUN mkdir -p /temp/prod
COPY package.json bun.lockb /temp/prod/
RUN cd /temp/prod && bun install --production

# copy node_modules from temp directory
# then copy all (non-ignored) project files into the image
FROM base AS prerelease
COPY --from=install /temp/dev/node_modules node_modules
COPY . .

ENV NODE_ENV=production
ENV NEXT_TELEMETRY_DISABLED 1

# RUN bun run test #todo: add here after adding tests
RUN bun run build

# copy production dependencies and source code into final image
FROM base AS release
WORKDIR /app

# Set correct permissions for nextjs user and don't run as root
RUN adduser crm
RUN chown crm:bun .
USER crm

COPY --from=install /temp/prod/node_modules node_modules
COPY --from=prerelease --chown=crm:bun /app/.next ./.next
COPY --from=prerelease /app/node_modules ./node_modules
COPY --from=prerelease /app/package.json ./package.json
COPY --from=prerelease /app/public ./public
CMD ["bun", "run", "build"]
# run the app
EXPOSE 3000/tcp
CMD ["bun", "start" ]
