2. 2Configure GitHub Actions to use the authenticated Docker credentials
3. 3Use `ssh` with the `-T` flag to disable interactive login and avoid TTY errors
4. 4Apply environment variables to store sensitive credentials securely
5. 5Test the deployment workflow to ensure successful authentication and deployment
