yarn install inside docker image with yarn workspaces

This code won't work outside of the docker vm, so it will refuse in the docker, too.

The problem is you have built a code, and copy the bundled code. The yarn workspaces is looking for a package.json that you don't have in the dist folder. The workspaces is just creating a link in a common node_modules folder to the other workspace that you are using. The source code is needed there. (BTW why don't you build code inside the docker vm? That way source code and dist would also be available.)

Here is my dockerfile. I use yarn workspaces and lerna, but without lerna should be similar. You want to build your shared libraries and then test the build works locally by running your code in your dist folder.
