Feature Request: Support for pnpm in Dockerfile Generation Based on packageManager Setting in nx.json

[liam-daley]

Description:

Currently, the @nx-tools/nx-container plugin generates Dockerfiles with npm commands for package installations, regardless of the package manager set in the nx.json file. To enhance compatibility and streamline development workflows, it would be beneficial for the plugin to dynamically adjust the Dockerfile to use pnpm commands when the packageManager setting in nx.json is set to 'pnpm'.

Proposed Feature:

1. Detect packageManager Setting:

   • Modify the Dockerfile generation logic to read the packageManager setting from nx.json.

2. Conditional Command Generation:

   • If packageManager is set to 'pnpm', use pnpm commands for installing packages in the generated Dockerfile.
   • Otherwise, default to npm commands.

Example Implementation:

• Current command with npm:

  RUN npm install --omit=dev

• Desired command with pnpm:

  RUN pnpm install --prod

Thank you for considering this feature request. I believe it will significantly benefit the Nx community by providing better integration with pnpm.
