Introduction
In the JS7 - Deployment process a Deployment Descriptor specifies
- which JS7 components of JOC Cockpit, Controller instances and Agents should be installed,
- where to install each JS7 component,
- which installation options to use, for example the installation directory,
- which configuration options to use, for example port usage.
Deployment Descriptors are specified from files in JSON format and include instructions, for example to deploy a larger number of Agents on target machines.
The JS7 - Deployment Packaging makes use of the Deployment Descriptor to install and to package JS7 components.
Deployment Descriptor
Deployment Descriptors are specified from .json files.
- Users are strongly encouraged to validate their .json files against the Deployment Descriptor Schema, see JS7 - Deployment Descriptor JSON Schema.
- The basic structure includes to specify an array of Agent objects.
Examples
Agents using HTTP Connections
The Deployment Descriptor specifies two Agents to be installed on two hosts:
- Host
centostest-primary and centostest-secondary each operate an Agent. - The Controller to which the Agents are registered is using the
testsuite Controller ID. - Agents make use of HTTP connections.

Agents using HTTPS Connections
The Deployment Descriptor specifies two Agents to be installed on two hosts:
- Host
centostest-primary and centostest-secondary each operate an Agent. - The Controller to which the Agents are registered is using the
testsuite Controller ID. - Agents use HTTPS connections and are equipped with certificates.
