Dockerhub - How to reference the packages folder during the app's docker build?

[oscarcoding]

Summary

A build in Dockerhub only runs in the context of the app's folder. So it throws a "not found" error when trying to reference packages/foo in the package.json of the my-app:

apps/my-app

• package.json has: "name": "@mine/my-app" and "dependencies": { "@mine/components": "^1.0.0" }
• Dockerfile with "RUN yarn build" - this is where it fails

packages/components

• package.json has "name": "@mine/components" and "version": "1.0.0"

It runs fine locally and the app can use the component no problem.

But when I commit to github, then Dockerhub build is triggered and fails with:

"Error: https://registry.yarnpkg.com/@mine/components: Not found"

Which makes sense - the dockerhub build runs in the context of the "my-app" folder, and cant see the "components" folder.

What is the correct way to resolve this?

I only just moved this my-app into turborepo, it has been live for a while and the Dockerfile is correct for building it when standalone.
