Describe the Bug

env.local is not copied in the runner phase. You will encounter issue if you use secret variables (non NEXT_PUBLIC env variables):

Expected Behavior

Add COPY --from=builder /app/.env.local .env.local in the runner phase to fix this issue

(PLEASE, challenge me if I’m wrong!)

Hello,

Why did you need to copy the .env.local file into the docker image?

If you want to pass the variables in the node.js context, you can just add the “environment” vars when you launch your images from the cli (with the -e option) or with the environment key in a docker-compose.yml.

Also, for the non-node.js context, the NEXT_PUBLIC_**** vars needs to be passed as build args only at the build time.

In the docs there is a note:

Note: similar to Default Environment Variables, .env.test file should be included in your repository, but .env.test.local shouldn’t, as .env*.local are intended to be ignored through .gitignore.

So If you have for example a Github action that builds your docker image at every new release, you simply can’t do the .env copy because you don’t have it in the repository.
