System logo configuration | Jems Documentation

General purpose

The purpose of this document is to provide an overview of how to manage logos in the Jems service.

Location and access

The Jems logo configuration is based on the system dependency Minio.

By default, Minio is accessible on the same host where the Jems service is running, with port number 9001.

To adapt the host name and port number for Minio, you should use docker-compose.yml or adapt the Minio startup parameters.

Please see the installation instructions for more information. Installation instructions

Please make sure that the firewall rules allow access to the Minio service.

Instructions to enable and disable access to Minio

The instructions below are related to CentOs

Enable access
sudo firewall-cmd --zone=public --permanent --add-service=http
sudo firewall-cmd --zone=public --permanent --add-port 9001/tcp
sudo firewall-cmd --reload

Don`t forget to close the firewall after you finished using the Minio service.
