Step 4: Deploy Your Application

1. Navigate to the ‘Deployments’ section in the Coolify dashboard.
2. Click on the ‘New Deployment’ button to initiate the deployment process.
3. Select your repository from either GitHub or GitLab. Ensure you have connected your account to Coolify beforehand.
4. Configure the build settings as required. This may include specifying the branch to deploy, environment variables, and any build commands needed.
5. Review your configuration and click on the ‘Deploy’ button to start the deployment.
6. Monitor the deployment progress in the dashboard. Check the logs for any errors or issues that may arise during the process.

Once the deployment is complete, your application should be accessible via your designated domain. Remember to test your application locally before deploying to ensure compatibility with the Coolify environment. If you encounter any errors, refer to the logs for troubleshooting.

Troubleshooting & Verification

If your application fails to deploy, check the logs for errors. Ensure that your environment variables are correctly set and that your repository is accessible. Verify that the required services are running and that your application meets all dependencies. Test the deployment locally before pushing to Coolify for smoother deployment.

Step 5: Monitor Your Application

1. Navigate to the ‘Monitoring’ section of your Coolify dashboard. This area provides a comprehensive overview of your application’s performance.

3. Set up alerts for critical metrics. This can be done by configuring thresholds for CPU and memory usage. Use the following command to set alerts:

   coolify set-alert --cpu-threshold 80 --memory-threshold 75

4. Regularly review your metrics to identify potential bottlenecks. Look for spikes in resource usage that may indicate performance issues.
5. If available, consider setting up auto-scaling to handle increased traffic. This can help maintain performance during peak times. Use the command:

   coolify enable-auto-scaling

Be cautious of high resource usage, as it may lead to performance issues. Keeping a close eye on these metrics will ensure your application runs smoothly.

Troubleshooting & Verification

If your application is not responding as expected, check the logs for errors. Ensure that all environment variables are correctly set. Use the built-in monitoring tools to track performance metrics. If issues persist, restart the application and verify network settings. Consult the documentation for specific error codes and resolutions.

Step 6: Update and Maintain Your Application

1. Push Changes to Your Repository: Whenever you make updates or changes to your application, commit those changes and push them to your version control repository. Use the following command:

   git add .

   git commit -m "Your commit message"

   git push origin main

2. Automatic Redeployment: Coolify will automatically detect the changes in your repository and redeploy your application. You can monitor the deployment status in the Coolify dashboard.
3. Regular Maintenance Checks: Schedule regular maintenance checks for your application to ensure everything is functioning correctly and to apply necessary updates.
4. Keep a Changelog: Maintain a changelog for your deployments to track changes over time. This helps in understanding what has been updated and when.

Neglecting updates can lead to security vulnerabilities, so it’s crucial to keep your application up-to-date and secure.

Troubleshooting & Verification

If you encounter issues after updating your application, check the deployment logs for errors. Ensure that all dependencies are correctly installed and compatible with the new version. Verify that environment variables are set properly. Test the application locally before redeploying to confirm that the update functions as intended.
