Docker Compose Detection Failure on Mixed Environments

[mohsinirfanpalla]

• 📖 DESCRIPTION
• ================================================================
• Universal Docker startup manager that eliminates the confusion
• between docker compose (plugin-based) and docker-compose (legacy binary).
• Automatically detects the available command, verifies Docker,
• and starts containers in detached mode.
• Features:
• • Cross-platform (macOS, Linux, Windows)
• • Auto-detects Compose flavor
• • Runs containers in detached mode
• • Safe shell execution
• • CI/CD-friendly logging
• How it works:
• 1. Checks Docker installation
• 2. Detects Compose variant
• 3. Executes up -d with correct command
• 4. Logs status and exits gracefully
• Use Cases:
• • Local development automation
• • CI pipelines
• • Open-source repos needing fast container spin-up
• Example:
• ts-node scripts/start-docker.ts
• node dist/scripts/start-docker.js
• ================================================================

}

if (!isDockerAvailable()) throw new Error("🚫 Docker is not installed or not found in PATH.");
const composeType = detectComposeType();
if (!composeType) throw new Error("🚫 Neither 'docker compose' nor 'docker-compose' is available.");
console.log("🐋 Docker detected!");
console.log(composeType === "plugin" ? "🧩 Using Docker Compose plugin..." : "⚙️ Using legacy docker-compose...");
const cmd = composeType === "plugin" ? "docker compose up -d" : "docker-compose up -d";
execSync(cmd, { stdio: "inherit", shell: true });
}

try {
console.log("🚀 Initializing Docker environment...");
startContainers();
console.log("✅ Containers started successfully!");
} catch (error) {
console.error(❌ Error: ${(error as Error).message});
process.exit(1);
}
