Describe the Bug

I am running sudo docker build -t myapp . (on a GCP VM) and I get this error below:

Step 21/26 : COPY --from=builder --chown=nextjs:nodejs /app/.next/standalone ./
COPY failed: stat app/.next/standalone: file does not exist

Note: I’ve done all required step for existing projects as described here.

Expected Behavior

Build the image without error

To Reproduce

• Copy Dockerfile in the base directory of your app
• Update next.config.js like so:

// next.config.js
module.exports = {
  // ... rest of the configuration.
  output: 'standalone',
}

• Run sudo docker build -t myapp .
