Configure a Rails project to work with Conductor (parallel coding agents)
Set up this Rails project for Conductor, the Mac app for parallel coding agents.
Create conductor.json in the project root if it doesn't already exist:
{
"scripts": {
"setup": "bin/conductor-setup",
"run": "script/server"
}
}
Create bin/conductor-setup if it doesn't already exist:
#!/bin/bash
set -e
# Symlink .env from repo root (where secrets live, outside worktrees)
[ -f "$CONDUCTOR_ROOT_PATH/.env" ] && ln -sf "$CONDUCTOR_ROOT_PATH/.env" .env
# Symlink Rails master key
[ -f "$CONDUCTOR_ROOT_PATH/config/master.key" ] && ln -sf "$CONDUCTOR_ROOT_PATH/config/master.key" config/master.key
# Install dependencies
bundle install
npm install
Make it executable with chmod +x bin/conductor-setup.
Create the script directory if needed, then create script/server if it doesn't already exist:
#!/bin/bash
# === Port Configuration ===
export PORT=${CONDUCTOR_PORT:-3000}
export WEB_PORT=$PORT
export VITE_RUBY_PORT=$((PORT + 1000))
# === SSR Port (for Inertia SSR server) ===
export INERTIA_SSR_PORT=$((PORT + 100))
export INERTIA_SSR_URL="http://localhost:${INERTIA_SSR_PORT}"
# === Redis Isolation ===
if [ -n "$CONDUCTOR_WORKSPACE_NAME" ]; then
HASH=$(printf '%s' "$CONDUCTOR_WORKSPACE_NAME" | cksum | cut -d' ' -f1)
REDIS_DB=$((HASH % 16))
export REDIS_URL="redis://localhost:6379/${REDIS_DB}"
fi
exec bin/dev
Make it executable with chmod +x script/server.
For each of the following files, if they exist and contain Redis configuration, update them to use ENV.fetch('REDIS_URL', ...) or ENV['REDIS_URL'] with a fallback:
If this file exists and configures Redis, update it to use:
redis_url = ENV.fetch('REDIS_URL', 'redis://localhost:6379/0')
If this file exists, update the development adapter to use:
