Reference on Open Component Model

Component Constructor

Mon, 01 Jan 0001 00:00:00 +0000

The OCM Component Constructor defines the input format for building component versions. It describes how resources and sources are provided – either via access specifications (referencing existing artifacts) or via input specifications (providing content directly).

Component Descriptor

Mon, 01 Jan 0001 00:00:00 +0000

The OCM Component Descriptor is the central data structure of the Open Component Model. It describes a component version with its resources, sources, references, labels, and signatures.

Credential Consumer Identities

Mon, 01 Jan 0001 00:00:00 +0000

This page is the technical reference for credential consumer identities — the key-value maps OCM uses to look up credentials for a given operation. For a high-level introduction, see Credential System.

Input and Access Types

Mon, 01 Jan 0001 00:00:00 +0000

Overview

Resources in a component version are added using either an input type or an access type.

Input type — embeds content by value. The content is stored alongside the component descriptor in the target repository.
Access type — stores an access specification pointing to the content. In the constructor, this typically references an external location (e.g. an OCI registry) rather than embedding the content.

A resource must have exactly one of input or access. See the Component Constructor reference for the full YAML schema.

Resolver Configuration

Mon, 01 Jan 0001 00:00:00 +0000

This page is the technical reference for OCM resolver configuration. For a high-level introduction, see OCM Resolvers.

Configuration File

Resolvers are configured in the OCM configuration file. By default, the CLI searches for configuration in $HOME/.ocmconfig. You can also specify a configuration file explicitly with the --config flag.

Resource Repositories

Mon, 01 Jan 0001 00:00:00 +0000

This page is the technical reference for built-in resource repositories. For an introduction to what resource repositories are and why they exist, see Concept: Resource Repositories.
