Additional context

After saving changes in page.tsx on the PC, the .next/server/chunks/ssr on PC is updated same as page.tsx in container. However .next/server/chunks/ssr in container remains not updated.

Isn't this COPY . . only going to copy the source once, when you build up the container? https://github.com/ArtoszBart/next-issue/blob/2e6ac6b3f252f172327d0ec22d205ad46ce1df63/Dockerfile.dev#L6

I'm pretty sure that if you want "outside" changes to be reflected inside the container in real time (without rebuilding), you need to mount the directory as a volume instead of just copying it.

I'm pretty sure that if you want "outside" changes to be reflected inside the container in real time (without restarting compose), you need to mount the directory as a volume instead of just copying.

Exactly. Volume mapping is in the docker-compose.yml file.

As I said earlier:

Same problem here in nextjs 15 doesnt work wit turbopack in nextjs 14.2.5 its work

nvm after I mirrored this one it works somehow: volumes:

- ./:/app
- ./apps/web/node_modules:/app/apps/web/node_modules
- ./apps/web/.next:/app/apps/web/.next

[ArtoszBart]

Downgraded to next@14.2.16:

With:

    volumes:
      - ./:/app

After saving changes in page.tsx on the PC, the .next/server/app/page.js both on PC and container is updated same as page.tsx in container. However changes in app running inside container remains not updated in browser. After page reload i have:

Server Error

Error: Could not find the module "/app/node_modules/next/dist/client/components/app-router.js#" in the React Client Manifest. This is probably a bug in the React Server Components bundler.

The same error occurs with:

    volumes:
      - ./:/app
      - ./node_modules:/app/node_modules
      - ./.next:/app/.next

Having same issue with "next": "^15.0.0". Adding volume change is updated in docker but log never compile the new update.
