description: Deploy Python Flask applications to Railway.app with environment configuration and webhook setup

When to use this skill

Deploy Flask LINE bots to Railway.app, configure environment variables, set up webhooks, and monitor deployments.

How to use it

Required Files

Procfile:

code
web: python main.py

requirements.txt:

code
Flask==3.0.0
line-bot-sdk==3.5.0
APScheduler==3.10.4
firebase-admin==6.2.0

main.py entry point:

python
if __name__ == "__main__":
    port = int(os.getenv("PORT", 5000))
    app.run(host="0.0.0.0", port=port)

Environment Variables

Set in Railway dashboard:

  • •LINE_CHANNEL_ACCESS_TOKEN - LINE Bot token
  • •LINE_CHANNEL_SECRET - Channel secret
  • •FIREBASE_CONFIG_JSON - Complete Firebase JSON

Deployment Steps

  1. •Connect GitHub repo to Railway
  2. •Set environment variables
  3. •Get generated domain URL
  4. •Configure LINE webhook: https://your-app.up.railway.app/callback

Monitoring

Add health check:

python
@app.route("/", methods=['GET'])
def health_check():
    return "Bot is running!", 200

View logs in Railway dashboard → Deployments → View Logs

Common Issues

  • •Crashed: Check Procfile and PORT usage
  • •Webhook 400: Verify LINE_CHANNEL_SECRET
  • •Firebase failed: Check JSON format in env var
  • •No scheduled jobs: Upgrade to Hobby plan ($5/mo)
