# # gitea-restore-database.sh Description
|
|
# This script facilitates the restoration of a database backup.
|
|
# 1. **Identify Containers**: It first identifies the service and backups containers by name, finding the appropriate container IDs.
|
|
# 2. **List Backups**: Displays all available database backups located at the specified backup path.
|
|
# 3. **Select Backup**: Prompts the user to copy and paste the desired backup name from the list to restore the database.
|
|
# 4. **Stop Service**: Temporarily stops the service to ensure data consistency during restoration.
|
|
# 5. **Restore Database**: Executes a sequence of commands to drop the current database, create a new one, and restore it from the selected compressed backup file.
|
|
# 6. **Start Service**: Restarts the service after the restoration is completed.
|
|
# To make the `gitea-restore-database.shh` script executable, run the following command:
|
|
# `chmod +x gitea-restore-database.sh`
|
|
# Usage of this script ensures a controlled and guided process to restore the database from an existing backup.
