Description

Add 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 processd by the selected templater.)

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.

    • mediaType string

      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.

    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.

      This OPTIONAL property describes regular expressions used to match files that should NOT be included in the tar file. It takes precedence over the include match.

    • includeFiles list of regex

      This OPTIONAL property describes regular expressions used to match files that should be included in the tar file. If this option is not given all files not explicitly excluded are used.

  • 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.

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}"
