Apply this guide to your situation

This answer covers “What to preserve when recreating a container”. Read it with the summary and confirm that the symptom and service match what you are experiencing. Available options can vary by plan and account setup.

  • Before changing anything, note what you expected, what happened and roughly when. Check whether the issue affects one page or the whole service.
  • Save the full error message and note recent changes. Hide passwords, access codes, personal data and keys before sharing screenshots or logs.
  • If a step requires administrator access, restarting services or editing server files, stop if you do not administer that server. Send support the service name, error and checks you have already made.

Prerequisites

  • Read access to the container configuration and a recent backup of persistent data.
  • Keep the service identifier available and do not share credentials.

Important warnings

  • Portal labels and options vary by product and provider. This guide explains the general process and does not confirm that the action is available in Anayil Panel.
  • Before confirming purchases, DNS changes, cancellations or deletions, review consequences, charges and recovery options.

Step-by-step walkthrough

1. Understand the situation

An image can be recreated, but data stored only inside the container may be lost. Before updating, identify volumes, databases, secrets and ports in use.

2. Follow the process carefully

Check the application definition and documentation to learn which paths must persist and how to export data. Back up secrets securely; do not copy them to a public repository.

3. Check the result

In a test environment, recreate the service and verify data, connectivity and logs before changing production. If there is no test environment, ask the administrator for a rollback plan.

Troubleshooting & Solutions

The expected option or status does not appear

Root cause: The service, plan, role or registrar may differ from what the guide assumes.

Resolution: Do not repeat the action. Confirm the provider, service and permissions, then contact support with the case reference.

Rollback and recovery plan

If you have not confirmed the change, go back and keep the current information. If you already confirmed it, do not make successive changes to compensate: save the confirmation and ask the provider for the recovery process for this service.
