| == Koji Content Generator Metadata Proposal ==
| | This document has moved to the [https://docs.pagure.org/koji/ Koji Documentation]. The new location is: |
|
| |
|
| This document describes the proposed Koji Content Generator Metadata Format (version 0). This is the metadata that should be provided by a Content Generator in order for the content to be imported and managed by Koji. If you have further questions about [[Koji/ContentGenerators|Content Generators]], please email koji-devel@lists.fedorahosted.org.

| == Format ==
| | You can submit changes to Koji's docs in [https://pagure.io/koji Pagure] |
| Content Generator Metadata for a single build is provided as a JSON map. The map has four top-level entries:
| |
| | |
| * metadata_version: The version of the metadata format used. Currently must be 0.
| |
| * build: A map containing information about the build.
| |
| * buildroots: A list of maps, one for each environment in which build output was generated, containing information about that environment.
| |
| * output: A list of maps, one map for each file that will be imported and managed by Brew.
| |
| | |
| === metadata_version ===
| |
| This is an integer which indicates the version of the metadata format contained in this file. It will start at 0 and be incremented as the metadata format evolves.
| |
| | |
| === build ===
| |
| The build map contains the following entries:
| |
| | |
| * name: The name of the build.
| |
| * version: The version of the build.
| |
| * release: The release of the build.
| |
| * source: The SCM URL of the sources used in the build.
| |
| * start_time: The time the build started, in seconds since the epoch.
| |
| * end_time: The time the build was completed, in seconds since the epoch.
| |
| | |
| === buildroots ===
| |
| Each map in the buildroots list contains the following entries:
| |
| | |
| * host: Map containing information about the host where the build was run.
| |
| ** os: The operating system that was running on the host.
| |
| ** arch: The processor architecture of the host.
| |
| * content_generator: Map containing information about the Content Generator which ran the build.
| |
| ** name: The short name of the Content Generator.
| |
| ** version: The version of the Content Generator.
| |
| * container: Map containing information about the container in which the build was run.
| |
| ** type: The type of container that was used, eg. none, directory, chroot, mock-chroot, kvm, docker
| |
| ** arch: The architecture of the container. May be different than the architecture of the host, eg. i686 container on x86_64 host.
| |
| * tools: List of maps containing information about the tools used to run the build. Each map contains:
| |
| ** name: Name of the tool used.
| |
| ** version: Version of the tool used.
| |
| * components: List of maps containing information about content installed in the build environment (if any). Each map is guaranteed to contain a '''type''' field, which determines what other fields are present in the map. For maps where '''type = rpm''', the following fields will be present:
| |
| ** name: The rpm name.
| |
| ** version: The rpm version.
| |
| ** release: The rpm release.
| |
| ** epoch: The rpm epoch.
| |
| ** arch: The rpm arch.
| |
| ** sigmd5: The SIGMD5 tag from the rpm header.
| |
| ** signature: The signature used to sign the rpm (if any).
| |
| * For maps where '''type = file''', the following fields will be present:
| |
| ** filename: The name of the file.
| |
| ** filesize: The size of the file.
| |
| ** checksum: The checksum of the file.
| |
| ** checksum_type: The checksum type used.
| |
| * The format may be extended with other types in the future.
| |
| * extra: A map containing information specific to the Content Generator that produced the files to import. For OSBS, the extra map should contain a osbs entry, which is a map with the following fields:
| |
| ** build_id: The ID of the build in OSBS.
| |
| ** builder_image_id: The ID of the image in OSBS that was used to run the build.
| |
| | |
| | |
| === output ===
| |
| Each map in the output list contains the following entries:
| |
| | |
| * filename: The name of the file.
| |
| * filesize: The size of the file.
| |
| * arch: The architecture of the file (if applicable).
| |
| * checksum: The checksum of the file.
| |
| * checksum_type: The checksum type used.
| |
| * type: The type of the file. Log files should use "log".
| |
| * components: If the output file is composed from other units, those should be listed here. The format is the same as the '''components''' field of a buildroot map.
| |
| * extra: Free-form, but should contain IDs that allow tracking the output back to the system in which it was generated (if that system retains a record of output). For docker, the extra map should contain a docker entry, which is a map with the following fields:
| |
| ** id: The ID of the docker image produced in the repo used by the build tool
| |
| ** parent_id: The parent ID of the docker image produced (if applicable).
| |
| ** destination_repo: The destination repo of the docker image was delivered to.
| |
| ** tag: The tag applied to the docker image in the destination repo.
