Common Glyph

Shared utility templates used by all glyphs.

Templates

• common.name - Resource naming with prefixes/suffixes
• common.labels - Standard Kubernetes labels
• common.annotations - Standard Kubernetes annotations
• common.validation - Input validation helpers
• common.infra-labels - Infrastructure labels

Usage Pattern

Common templates are invoked differently than other glyphs:

{{- include "common.name" $root }}
{{- include "common.labels" $root | nindent 4 }}

Note: Direct context passing ($root), not list pattern.

Functions

common.name

Generates resource name with optional prefix/suffix.

Input: $root context

Output: String name

common.labels

Generates standard Kubernetes labels: - app.kubernetes.io/name - app.kubernetes.io/instance - app.kubernetes.io/version - app.kubernetes.io/managed-by - Custom labels from values

Input: $root context

Output: YAML label block

common.annotations

Generates standard annotations plus custom annotations from values.

Input: $root context

Output: YAML annotation block

Examples

Usage in Glyph Template

{{- define "myglyph.resource" -}}
apiVersion: v1
kind: ConfigMap
metadata:
  name: {{- include "common.name" $root }}
  labels:
    {{- include "common.labels" $root | nindent 4 }}
  annotations:
    {{- include "common.annotations" $root | nindent 4 }}
{{- end }}

Testing
