Setup Athenz UI


The following tools are required to be installed on hosts configured to run UI server.


UI Server is a Node.js application.

Node.js JavaScript Runtime

Verify that you have the required minimum version of node and nodemon binaries installed on your system and are included in your runtime path:

$ node --version
$ npm install -g nodemon
$ nodemon --version

Getting Software

Download latest Athenz UI release from Bintray - click on the Files tab, choose the latest version directory and then download the athenz-ui-<latest-version>-bin.tar.gz file:


$ tar xvfz athenz-ui-X.Y-bin.tar.gz
$ cd athenz-ui-X.Y


To run UI Server, the system administrator must generate the keys, certificates and make necessary changes to the configuration settings. For our configuration script we need the ZMS server hostname and a copy of the server certificate file since ZMS Server is running with a self-signed certificate. From your ZMS Server installation, copy the zms_cert.pem file from the athenz-zms-X.Y/var/zms_server/certs directory to a local directory on the host that will be running the UI Server. For the zms-public-cert-path argument below pass the full path of the zms_cert.pem.

$ cd athenz-ui-X.Y
$ bin/ <zms-hostname> <zms-public-cert-path>

Running this setup script completes the following tasks:

  • Generate a unique public/private key pair that UI Server will use to sign user's authorized service tokens. The UI has already been authorized to be allowed to carry out the users' requested operations.
  • Generate a self-signed X509 certificate for UI Server HTTPS support
  • Create a new domain called athenz and register the ui service in that domain

Start/Stop UI Server

Set the following environment variable before starting the UI Server:

$ export UI_SERVER=<ui-server-host-name> ZMS_SERVER=<zms-server-host-name>
$ cd athenz-ui-X.Y
$ bin/athenz_ui start

Based on the sample configuration file provided, Athenz UI Server will be listening on port 9443.

To stop the UI server, execute the following commands:

$ export UI_SERVER=<ui-server-host-name> ZMS_SERVER=<zms-server-host-name>
$ cd athenz-ui-X.Y
$ bin/athenz_ui stop

UI Access

To access Athenz UI in your browser, visit:


Since the development setup is using self-signed X509 certificates for Athenz ZMS and UI servers, the administrator must add exceptions when accessing Athenz UI or install the self-signed certificates for those two servers into his/her own web browser.

The administrator must first access the ZMS Server endpoint in the browser to accept the exception since the Athenz UI contacts ZMS Server to get an authorized token for the user when logging in. The administrator must access:


first and accept the certificate exception before accessing Athenz UI.

Alternatively, the administrator may decide to install the self-signed certificates for the ZMS and UI servers in their browser. For ZMS Server, the self-signed certificate is called zms_cert.pem and this file is located in the athenz-zms-X.Y/var/zms_server/certs directory. For UI Server, the self-signed certificate is called ui_cert.pem and this file is located in the athenz-ui-X.Y/keys directory.
