 - If you don’t mount volumes, all data will be lost when the container is removed.
- Certificate files will be automatically generated on first startup and persisted to the host at `/var/lib/crossdesk/certs`.
+- Certificate files will be automatically generated on first startup and persisted to the host at `/var/lib/crossdesk/certs`.As the default certificates are self-signed and cannot guarantee security, it is strongly recommended to apply for a trusted certificate from a cloud provider, deploy it to this directory, and restart the service.
