PodIntent for Cartographer Conventions

This reference topic describes PodIntent that you can use with Cartographer Conventions.

The conditional criteria governing the application of a convention is customizable and is based on the evaluation of a custom Kubernetes resource called PodIntent.

PodIntent applies conventions to a workload. A PodIntent is created, or updated, when a workload is run by using a Tanzu Application Platform supply chain.

The .spec.template PodTemplateSpec is enriched by the conventions and exposed as the .status.template PodTemplateSpec. A log of which sources and conventions are applied is captured with the conventions.carto.run/applied-conventions annotation on the PodTemplateSpec.

For example:

apiVersion: conventions.carto.run/v1alpha1
kind: PodIntent
metadata:
  name: sample
spec:
  template:
    spec:
      containers:
      - name: workload
        image: ubuntu
