Dockerize next.js 13 docker-compose.yml

Quick Fix: Avoid mounting the entire /app directory as a volume. Instead, only mount the necessary files or directories. Alternatively, run npm run build after starting the container to ensure that the built artifacts are available inside the container.

The Problem:

Dockerize a Next.js 13 application using a Docker Compose configuration file (docker-compose.yml). Encountering an error with ENOENT: no such file or directory related to BUILD_ID. Want to resolve the issue and successfully run the application in a Docker container.

The Solutions:

Solution 1: Prevent Files From Being Overwritten by Mounted Volume

The error message suggests that the file /app/.next/BUILD_ID is missing when the container starts. This is because the Docker Compose volume C:\Users\user\WorkSpace\Test\Docker\app\my-app:/app mounts the entire /app directory from the host machine into the container. Consequently, the files that you copied and built in the Dockerfile are overwritten by the files from the mounted volume, which don’t include the /app/.next/BUILD_ID file.

To resolve this issue, you can prevent the Docker Compose volume from overwriting the files built in the Dockerfile. Here’s how you can do that:

Create an empty directory on the host machine that will be used as a mount point for the container’s /app directory. For example, you can create a directory named docker-next-app-data on your host machine:

mkdir ~/docker-next-app-data

Modify the volumes section in your docker-compose.yml file to mount the docker-next-app-data directory instead of the entire /app directory:

volumes:
  - ~/docker-next-app-data:/app

Run docker-compose up --build as usual.

Now, when the container starts, it will use the empty docker-next-app-data directory as its /app directory. The files that you copied and built in the Dockerfile will be preserved, and the /app/.next/BUILD_ID file will be present. This should resolve the error message that you were encountering.

Here is the updated docker-compose.yml file:

version: '3.8'

services:

  next-app:
    build:
      context: .
      dockerfile: C:\Users\user\WorkSpace\Test\Docker\app\my-app\Dockerfile
    ports:
      - '3000:3000'
    volumes:
      - ~/docker-next-app-data:/app
    environment:
      - NODE_ENV=production

Q&A

How to fix error ENOENT: no such file or directory, open ‘/app/.next/BUILD_ID’?

—

Run ‘npm run build’ after starting the container.

How to expose port 3000?

—

Use ‘ports’ in docker-compose.yml to map port 3000 inside the container to port 3000 on the host machine.
