Sim CLI

Sim CLI allows you to run Sim using Docker with a single command.

Installation

To install the Sim CLI globally, use:

npm install -g simstudio

Usage

To start Sim, simply run:

simstudio

Options

  • -p, --port <port>: Specify the port to run Sim on (default: 3000).
  • --no-pull: Skip pulling the latest Docker images.

Requirements

  • Docker must be installed and running on your machine.

Data and secrets

Everything lives under ~/.simstudio:

  • data/postgres — the database volume.
  • secrets.env — secrets generated for this install on first run, then reused.

Keep secrets.env. ENCRYPTION_KEY and API_ENCRYPTION_KEY decrypt data already stored in the database, so replacing them leaves that data unreadable. Back the file up alongside data/.

You can supply your own values by editing it. The format is KEY=value, one per line, with # for comments — quotes are not interpreted, so leave them off.

Key Requirement
ENCRYPTION_KEY, API_ENCRYPTION_KEY exactly 64 hex characters (openssl rand -hex 32)
BETTER_AUTH_SECRET, INTERNAL_API_SECRET at least 32 characters, otherwise free-form

A value that does not meet its requirement is regenerated on the next run. When that replaces something you had set, the CLI says so and copies the previous file to secrets.env.bak-<time>.
