Object Creator
Overview
Expert guidance for creating Infrahub object (data) files. Objects are YAML files that populate schema nodes with actual infrastructure data -- devices, locations, organizations, modules, and more.
Project Context
Existing schema files: !find . -name ".yml" -path "/schemas/" -o -name "schema" -name ".yml" 2>/dev/null | head -10
Existing object files: !find . -name ".yml" -path "/objects/*" 2>/dev/null | head -20
If invoked with arguments (e.g., /infrahub:managing-objects DcimDevice spine-01), use the first argument as the kind and remaining arguments as object details.
When to Use
- Creating new data files for infrastructure objects
- Populating devices, locations, organizations, or other schema nodes
- Setting up hierarchical data (location trees, tenant groups)
- Referencing related objects across files
- Managing component children (interfaces, modules)
- Organizing object files for correct load order
Rule Categories
| Priority | Category | Prefix | Description |
|---|---|---|---|
| CRITICAL | Branch-First Loading | workflow- |
Load onto a branch, not the default branch |
| CRITICAL | File Format | format- |
apiVersion, kind, spec structure |
| CRITICAL | Value Mapping | value- |
Attributes, dropdowns, references |
| HIGH | Children | children- |
Hierarchy/component nesting |
| MEDIUM | Range | range- |
Sequential interface expansion |
| MEDIUM | Organization | organization- |
Naming, load order, multi-doc |
| LOW | Patterns | patterns- |
Flat lists, devices, git repos |
Schema Features This Skill Depends On
Object files reference schema-defined shapes; missing schema setup turns into "object failed to load" or "reference not found" errors at sync time. Before populating data, verify the schema upstream:
| If the object... | The schema must... | See |
|---|---|---|
| References another object across files | Define humanfriendlyid on the target node (the shape determines scalar-vs-list reference) |
[../infrahub-managing-schemas/rules/display-human-friendly-id.md](../infrahub-managing-schemas/rules/display-human-friendly-id.md) |
| Sits in a location/parent tree | Use a hierarchical generic with parent/children and full-kind peer references |
[../infrahub-managing-schemas/rules/hierarchy-setup.md](../infrahub-managing-schemas/rules/hierarchy-setup.md) |
| Sets a Dropdown attribute value | Declare the dropdown choices as objects with name (not bare strings); the object references the choice name |
[../infrahub-managing-schemas/rules/attribute-defaults-and-types.md](../infrahub-managing-schemas/rules/attribute-defaults-and-types.md) |
| Owns Component children inline | The parent's Component relationship and child's Parent relationship must share an identifier and the child needs optional: false |
[../infrahub-managing-schemas/rules/relationship-component-parent.md](../infrahub-managing-schemas/rules/relationship-component-parent.md) |
| Will be the target of an artifact pipeline | The concrete node must inherit_from: CoreArtifactTarget (set on the node, not on a generic) |
[../infrahub-managing-schemas/rules/extension-artifact-target.md](../infrahub-managing-schemas/rules/extension-artifact-target.md) |
If any of these is missing, the schema needs an update before the objects can load — that's a schema migration, not an object fix.
Object File Basics
---
apiVersion: infrahub.app/v1
kind: Object
spec:
kind: <NodeKind> # Schema node kind (e.g., DcimDellServer)
data:
- <attribute>: <value> # List of object instances
apiVersion, kind: Object, spec.kind, and spec.data are always required. Each spec block targets a single node kind.
Workflow
Follow these steps when creating object data files:
- Plan to load onto a branch, not the default branch —
Decide the dedicated branch this data will load onto before writing the files, and surface it when you hand off the load commands. Loading into the default branch (the target when no --branch is given — main by convention, but it can be renamed) writes unreviewed data to the source of truth, and a bad bulk load there means deleting objects one by one instead of discarding a branch. Read [rules/workflow-branch-first.md](./rules/workflow-branch-first.md). The default branch is only reasonable on a local throwaway instance.
- Read the schema — Identify the target node kind,
its attributes, relationships, and whether it has component children or hierarchy parents.
- Plan the file structure — Read
[rules/format-structure.md](./rules/format-structure.md) for the required YAML structure and [rules/organization-load-order.md](./rules/organization-load-order.md) for file naming and load order conventions.
- Map attribute values — Set each attribute using
the correct value format. Read [rules/value-attributes.md](./rules/value-attributes.md) for attribute mapping and [rules/value-relationships.md](./rules/value-relationships.md) for relationship references. If the object should inherit shared defaults from a Profile or be created from an Object Template, read [rules/value-profiles-templates.md](./rules/value-profiles-templates.md). To stamp lineage or lock a value, write it as a value + metadata mapping — see [../infrahub-common/metadata-lineage.md](../infrahub-common/metadata-lineage.md) (remember source is lineage only; locking needs owner + is_protected).
- Handle children — If the node has component
children or hierarchy nesting, read [rules/children-components.md](./rules/children-components.md) and [rules/children-hierarchy.md](./rules/children-hierarchy.md).
- Validate and load on the branch — Check YAML syntax,
ensure referenced objects exist or are defined in earlier load-order files, then validate and load against your branch (--branch). See [validation.md](./validation.md) for the commands and pre-load checklist.
