Introduction

In the JS7 - Deployment process a Deployment Descriptor specifies

  • which JS7 products of JOC Cockpit, Controller instances and Agents should be installed,
  • where to install each JS7 product,
  • 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 products.

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 Controller objects.

Examples

Standalone Controller using HTTP Connections

The Deployment Descriptor specifies a Standalone Controller to be installed:

  • Host centostest-primary operates the Controller instance.
  • The Controller makes use of HTTP connections.

Standalone Controller using HTTPS Connections

The Deployment Descriptor specifies a Standalone Controller to be installed:

  • Host centostest-primary operates the Controller instance.
  • The Controller makes use of HTTPS connections and is equipped with a certificate.
