Description

Adds resources specified in a resource file to a component version. So far, only component archives are supported as target.

This command accepts resource specification files describing the resources to add to a component version. Elements must follow the resource meta data description scheme of the component descriptor. Besides referential resources using the access attribute to describe the access method, it is possible to describe local resources fed by local data using the input field (see below).

The description file might contain:

a single resource
a list of resources under the key resources
a list of yaml documents with a single resource or resource list

It is possible to describe a single resource via command line options. The meta data of this element is described by the argument of option –resource, which must be a YAML or JSON string. Alternatively, the name and version can be specified with the options –name and –version. With the option –extra it is possible to add extra identity attributes. Explicitly specified options override values specified by the –resource option. (Note: Go templates are not supported for YAML-based option values. Besides this restriction, the finally composed element description is still processed by the selected template engine.)

The resource type can be specified with the option –type. Therefore, the minimal required meta data for elements can be completely specified by dedicated options and don’t need the YAML option.

To describe the content of this element one of the options –access or –input must be given. They take a YAML or JSON value describing an attribute set, also. The structure of those values is similar to the access or input fields of the description file format. Non-local resources can be indicated using the option –external.

All yaml/json defined resources can be templated. Variables are specified as regular arguments following the syntax <name>=<value>. Additionally settings can be specified by a yaml file using the –settings option. With the option –addenv environment variables are added to the binding. Values are overwritten in the order environment, settings file, command line settings.

Note: Variable names are case-sensitive.

Example:

<command> <options> -- MY_VAL=test <args>

There are several templaters that can be selected by the –templater option:

go go templating supports complex values.
```
  key:
    subkey: "abc {{.MY_VAL}}"
```
none do not do any substitution.
spiff spiff templating.
It supports complex values. the settings are accessible using the binding values.
```
  key:
    subkey: "abc (( values.MY_VAL ))"
```
subst simple value substitution with the drone/envsubst templater.
It supports string values, only. Complex settings will be json encoded.
```
  key:
    subkey: "abc ${MY_VAL}"
```

The resource specification supports the following blob input types, specified with the field type in the input field:

Input type binary
This blob type is used to provide base64 encoded binary content. The specification supports the following fields:
- data []byte
  The binary data to provide.

  This OPTIONAL property describes the media type to store with the local blob. The default media type is application/octet-stream and application/gzip if compression is enabled.

  This OPTIONAL property describes whether the content should be stored compressed or not.
Options used to configure fields: –inputCompress, –inputData, –mediaType
Input type dir
The path must denote a directory relative to the resources file, which is packed with tar and optionally compressed if the compress field is set to true. If the field preserveDir is set to true the directory itself is added to the tar. If the field followSymLinks is set to true, symbolic links are not packed but their targets files or folders. With the list fields includeFiles and excludeFiles it is possible to specify which files should be included or excluded. The values are regular expression used to match relative file paths. If no includes are specified all file not explicitly excluded are used.
This blob type specification supports the following fields:
- path string
  This REQUIRED property describes the file path to directory relative to the resource file location.
- mediaType string
  This OPTIONAL property describes the media type to store with the local blob. The default media type is application/x-tar and application/gzip if compression is enabled.

They should be built with the “buildx” command for cross platform docker builds (see https://ocm.software/docs/tutorials/best-practices/#building-multi-architecture-images). The denoted images, as well as the wrapping image index, are packed as OCI artifact set. They will contain an informational back link to the component version using the manifest annotation software.ocm/component-version.

  This OPTIONAL property can be set, if the helm chart should be loaded from a helm repository instead of the local filesystem. It describes the base URL of the chart repository. If specified, the path field must describe the name of the chart in the chart repository, and version must describe the version of the chart imported from the chart repository

The following list describes the supported access methods, their versions and specification formats. Typically there is special support for the CLI artifact add commands. The access method specification can be put below the access field. If always requires the field type describing the kind and version shown below.

Access type gitHub
This method implements the access of the content of a git commit stored in a GitHub repository.
The following versions are supported:
- Version v1
  The type specific specification fields are:
  - repoUrl string
    Repository URL with or without scheme.
  - ref (optional) string
    Original ref used to get the commit from
  - commit string
    The sha/id of the git commit
Options used to configure fields: –accessHostname, –accessRepository, –commit
Access type helm
This method implements the access of a Helm chart stored in a Helm repository.
The following versions are supported:
- Version v1
  The type specific specification fields are:
  - helmRepository string
    Helm repository URL.
  - helmChart string
    The name of the Helm chart and its version separated by a colon.
  - version string
    The version of the Helm chart if not specified as part of the chart name.
  - caCert string
    An optional TLS root certificate.
  - keyring string
    An optional keyring used to verify the chart.
  It uses the consumer identity type HelmChartRepository with the fields for a hostpath identity matcher (see ocm get credentials).
Options used to configure fields: –accessRepository, –accessVersion, –package
Access type localBlob
This method is used to store a resource blob along with the component descriptor on behalf of the hosting OCM repository.
Its implementation is specific to the implementation of OCM repository used to read the component descriptor. Every repository implementation may decide how and where local blobs are stored, but it MUST provide an implementation for this method.
Regardless of the chosen implementation the attribute specification is defined globally the same.
The following versions are supported:
- Version v1
  The type specific specification fields are:
  - localReference string
    Repository type specific location information as string. The value may encode any deep structure, but typically just an access path is sufficient.
  - mediaType string
    The media type of the blob used to store the resource. It may add format information like +tar or +gzip.
  - referenceName (optional) string
    This optional attribute may contain identity information used by other repositories to restore some global access with an identity related to the original source.
    For example, if an OCI artifact originally referenced using the access method ociArtifact is stored during some transport step as local artifact, the reference name can be set to its original repository name. An import step into an OCI based OCM repository may then decide to make this artifact available again as regular OCI artifact.
  - globalAccess (optional) access method specification
    If a resource blob is stored locally, the repository implementation may decide to provide an external access information (independent of the OCM model).
    For example, an OCI artifact stored as local blob can be additionally stored as regular OCI artifact in an OCI registry.
    This additional external access information can be added using a second external access method specification.
