PMG Sandbox Profiles

This directory contains built-in sandbox policies for PMG package managers.

Available Profiles

npm-restrictive

Restrictive policy for the npm ecosystem (npm, pnpm, yarn, bun).

pypi-restrictive

Restrictive policy for the PyPI ecosystem (pip, pip3, poetry, uv).

Custom Policies

You can create custom sandbox policies by:

  1. Copying one of the built-in profiles
  2. Modifying the rules to suit your needs
  3. Referencing the custom profile in your PMG config:
sandbox:
  enabled: true
  policies:
    npm:
      enabled: true
      profile: /path/to/custom-npm-policy.yml

Policy Schema

See the Policy Schema Documentation for details on the YAML structure.

Supported Variables

  • ${CWD}: Current working directory
  • ${TMPDIR}: Temporary directory
