Setup ZTS (authoriZation Token System)


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


ZTS Server is written in Java and using embedded Jetty.

Oracle Java Platform JDK 8

While ZTS has been developed and tested with Oracle Java Platform JDK 8 it should run successfully with OpenJDK 8 as well.

Getting Software

Build the latest ZTS binary release by following the development instructions. The binary release packages will be created automatically in the assembly subdirectory. Copy the athenz-zts-X.Y-bin.tar.gz to your desired setup directory.

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


To run ZTS Server, the system administrator must generate the keys, certificates and make necessary changes to the configuration settings. Since ZMS Server is running with a self-signed certificate, we need to generate a truststore for the java http client to use when communicating with the ZMS Server. For our configuration script we need the ZMS server hostname and a copy of the server certificate file. 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 ZTS Server. For the zms-public-cert-path argument below pass the full path of the zms_cert.pem.

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

Running this setup script completes the following tasks:

  • Generate a unique private key that ZTS Server will use to sign any ZTokens it issues
  • Generate a self-signed X509 certificate for ZTS Server HTTPS support
  • Generate a truststore for secure communication with the ZMS Server
  • Registers the zts service in Athenz sys.auth domain
  • Generates an Athenz configuration file

Athenz CA X.509 Certificate Issuing

For authenticating services using X509 certificates, ZTS Servers expect the configured cert signer factory class names in its athenz.zts.cert_signer_factory_class system property. Self Cert Signer is a sample implementation of cert Signer we have for development environment.

You can use SelfCertSigner or have your implementation of Cert Signer.

Refer Certificate Signer for full details how to implement your cert signer.

Start/Stop ZTS Server

Start the ZTS Server by executing:

$ cd athenz-zts-X.Y
$ bin/zts start

Based on the sample configuration file provided, ZTS Server will be listening on port 8443.

Stop the ZTS Server by executing:

$ cd athenz-zts-X.Y
$ bin/zts stop
