Preparing a shared template

This page describes StackState version 4.0.

The StackState 4.0 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.0 version range to upgrade to a more recent release.

Go to the documentation for the latest StackState release.

Shared template file contains information that is going to be used across instances, like: Component Types, IdExtractor functions for components and relations, Component Template functions, Relation Template functions, or Layers. They can be derived from the exported .stj file, by exporting configuration nodes with shared in their identifiers, e.g. "identifier": "urn:stackpack:{StackPackName}:shared:relation-template-function:test-relation-template",.

Shared template file contains information that is going to be used across instances, like:

Component Types

Component Type in a template file contains an icon image that is coded in png;base64 as in the example below:

{
"_type": "ComponentType", 
"name": "exchange_server", 
"id": -147, 
"identifier": "urn:stackpack:{{StackPackName}}:shared:component-type:exchange-server", 
"iconbase64": "{{ include "./icons/icon.png" "base64" }}" 
},

Relation Types

Contains Relation name and direction.

  {
  "_type": "RelationType",
  "name": "hosted_on",
  "id": -121,
  "identifier": "urn:stackpack:{{StackPackName}}:shared:relation-type:hosted_on",
  "dependencyDirection": "ONE_WAY"
  }
