Usage: $(basename "$0") --from FILE [options]
|
|
|
|
Restores a full database dump (produced by db-export.sh) into a MySQL instance.
|
|
Works with both the local Docker container and a remote MySQL server.
|
|
|
|
Options:
|
|
--from FILE Dump file to restore (.sql or .sql.gz) (required)
|
|
--host HOST Target MySQL host (default: 127.0.0.1)
|
|
--port PORT Target MySQL port (default: 3306)
|
|
--user USER Target MySQL user (default: root)
|
|
--password PASS Target MySQL password (default: from .env DOCKER_DB_ROOT_PASSWORD)
|
|
--dry-run Show what would happen without executing
|
|
--force Skip the confirmation prompt
|
|
-h, --help Show this help
|
|
|
|
Examples:
|
|
# Restore into local Docker container (new server, container must be running)
|
|
$(basename "$0") --from backups/2025-01-01_12-00-00.sql.gz
|
|
|
|
# Restore into a remote MySQL server
|
|
$(basename "$0") --from backups/dump.sql.gz \\
|
|
--host db.example.com --port 3306 \\
|
|
--user root --password secret
