Provenance transform

This topic tells you about the Application Accelerator Provenance transform in Tanzu Application Platform (commonly known as TAP).

The Provenance transform is a special transform used to generate a file that provides details of the accelerator engine transform.

Syntax reference

type: Provenance
condition: <SpEL expression>

The Provenance transform is added as a child to the top-most transform, which is usually a Merge or a Chain, using a Combo.

Behavior

The Provenance transform ignores its input and outputs a single resource named accelerator-info.yaml. For example:

id: <unique GUID of invocation>
timestamp: <timestamp in RFC3339 format>
username: <captured username of user triggering the run>
source: <client environment from which accelerator was run>
accelerator:
  name: <name of registered accelerator>
  git:
    url: <git repository location>
    ref:
      branch: <branch name> or
      tag: <tag name> or
      commit: <specific requested commit>
    subPath: <optional subpath inside the repo>
    commit: <actual SHA the branch or tag pointed to>
fragments:
  - name: <name of registered fragment 1>
    git:
      url: <git repository location>
      ref:
        branch: <branch name> or
        tag: <tag name> or
        commit: <specific requested commit>
      subPath: <optional subpath inside the repo>
      commit: <actual SHA the branch or tag pointed to>
  - name: <name of registered fragment 2>
    git:
      url: <git repository location>
      ref:
        branch: <branch name> or
        tag: <tag name> or
        commit: <specific requested commit>
      subPath: <optional subpath inside the repo>
      commit: <actual SHA the branch or tag pointed to>
  - ...
options:
  - name: <option name>
