Prepare instance template files
This page describes StackState version 4.2.
The StackState 4.2 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.2 version range to upgrade to a more recent release.
When preparing an instance specific template file, please keep in mind that you will use some of the identifiers that point to the shared template file. It is highly recommended to prepare your shared template first.
In this file you need to provide configuration blocks for the DataSource used by this instance, Topology information, QueryViews, etc. You can identify them in your export
.stj file by identifier with instance entry, for example "urn:stackpack:{{StackPackName}}:instance:{{instanceId}}:sync:test". However, this file also requires pointers to functions, Component templates, and Relation templates from the shared template file as in the below example:Also, in this file you need to provide mapping functions called
componentActions from the shared-template file to execute on the instance nodes:Synchronizations and componentActions mappings

After getting Synchronizations and Mappings from the shared-template into your instance-specific file, you can start looking for instance-specific blocks in the STJ export and copy them to your instance-specific template. You can quickly identify instance specific blocks, as their Identifier contains
instance:{{instanceId}} segment.DataSources
