  • options - a hash of supported options, depending on type
    • for s3:
      • access_key - access key for private S3 endpoints
      • secret_key - secret key for private S3 endpoints
      • role_arn - role arn for private S3 endpoints when using AssumeRole
• mirror_files - a list of mirror configurations for mirroring files (used by out)
  • destination - the mirror URI for uploading files (templated; Name, Version, SHA1, SHA256, SHA512, MD5)
  • location - the ISO3166-1 alpha-2 country code for the geographical location (embedded in the metalink)
  • priority - a priority for the file (embedded in the metalink)

Operations

check

Check for new versions in the repository.

Metadata:

• version - semantic version (e.g. 4.1.2)

in

Download and verify the referenced file(s).

• .resource/metalink.meta4 - metalink data used when downloading the file
• .resource/version - version downloaded (e.g. 4.1.2)
• * - the downloaded file(s) from the metalink

Parameters:

• include_files - a list of file globs to match when downloading files (intersects with include_files from source configuration, when present)
• skip_download - do not download blobs (only metalink.meta4 and version will be available)

out

Publish a metalink file to the repository.

Parameters:

• metalink - path to the metalink file (one of metalink or files must be configured)
• files - a list of glob paths for files to create a metalink from (one of metalink or files must be configured; requires version)
• version - path to a file with the version number (only effective with files)
• rename - publish the metalink file with a different file name (templated; Version)
• rename_from_file - path to a file whose content is the metalink file name (alternative to rename)
• options - a hash of supported options, depending on the repository type
  • for git repositories
    • author_name, author_email - the commit author
    • message - the commit message

Usage

To use this resource type, you should configure it in the resource_types section of your pipeline.

- name: metalink-repository
  type: docker-image
  source:
    repository: dpb587/metalink-repository-resource

URL Credentials

When working with authenticated URLs (for either upload or download), configure the url_handlers option of the resource:

url_handlers:
- type: s3
  options:
    access_key: AKIAA1B2C3...
    secret_key: a1b2c3d4e5...

When using multiple URLs which require different configurations, use the include or exclude options to restrict usage:

url_handlers:
- type: s3
  include:
  - s3://[^/]+/org1-bucket-name/
  options:
    access_key: AKIAA1B2C3...
    secret_key: a1b2c3d4e5...
- type: s3
  include:
  - s3://[^/]+/org2-bucket-name/
  options:
    access_key: AKIAB2C3D4...
    secret_key: b2c3d4e5f6...
	mirror_files:
- destination: s3://s3-external-1.amazonaws.com/org1-bucket-name/my-private-blobs/{{.Version}}/{{.Name}}
- destination: s3://s3-external-1.amazonaws.com/org2-bucket-name/my-private-blobs/{{.Version}}/{{.Name}}

Filters

The fileversion and repositorypath filters are supported.

filters:
- repositorypath: prefix-*.meta4
- fileversion: 27.x              # equivalent to using source version
