0.18.0

🌟 Features

• Support to build layers with docker for easier migration of existing images (for example with RUN apt install ... commands)

ℹ️ Miscellaneous

• Updated dependencies

0.17.0

🌟 Features

• Better modeling of OCI variant and their attributes that fits better with both the OCI model and the Gradle model
  • Only 1 OCI variant for each platform instead of 2 of which one was internal previously
  • Differentiation between an OCI image variant (with layers) and an OCI image index variant
    The io.github.sgtsilvio.gradle.distributiontype attribute can have the value oci-image-index in addition to oci-image
  • The io.github.sgtsilvio.gradle.platform attribute does not have weird non-platform values universal and multi anymore
    universal is modeled by not setting the attribute which fits well to the semantics of Gradle attributes
    multi is handled via the oci-image-index distribution type
  • The new model allows for a more robust image dependency resolution. The previous model was a bit hacky and required some workarounds.
• Support Gradle 8.11
  • Support requireFeature new in Gradle 8.11 (https://docs.gradle.org/8.11/release-notes.html#api-for-selecting-variants-by-feature-name)
  • Avoid deprecation warnings

✨ Improvements

• Changed OciImageDefinition.capabilities to a SetProperty<Capability>

ℹ️ Miscellaneous

• Require Gradle 7.6.4 or 8.3 or higher (instead of 7.4 or higher)
• Updated dependencies

0.16.0

🌟 Features

• New and improved extension of test suites and test tasks: OciTestExtension
  (accessible via OciExtension.of(TestSuite/TaskProvider<Test>))
  Example of old version:

  ociImageDependencies.forTest(tasks.test) {
      runtime("foo:bar:1.2.3")
      val scope2Runtime = runtimeScope("scope2")
      scope2Runtime("foo:bar:2.3.4")
  }
  tasks.named("testOciRegistryData", oci.imagesTaskClass) {
      platformSelector = oci.platformSelector(oci.platform("linux", "amd64"))
  }

  Example of new version:

  oci.of(tasks.test) {
      imageDependencies {
          runtime("foo:bar:1.2.3")
      }
      imageDependencies("scope2") {
          runtime("foo:bar:2.3.4")
      }
      platformSelector = platformSelector(platform("linux", "amd64"))
  }

  • Added platformSelector property
  • Improved declaration of multiple image dependency scopes: imageDependencies, imageDependencies(scope)
  • Allow configuration on test suite and individual test tasks at the same time
    This allows to restrict platforms on different test suite targets

✨ Improvements

• Improve recognizability of parent images as dependencies inside an image definition
  Example of old version:

  //imageDefinition.register("main") {
      //allPlatforms {
          parentImages {
              add("foo:bar:1.2.3")
          }

  Example of new version:

  //imageDefinition.register("main") {
      //allPlatforms {
          dependencies {
              runtime("foo:bar:1.2.3")
          }
  

ℹ️ Miscellaneous

• Updated dependencies

0.15.1

🐞 Bug fixes

• Removed unnecessary print statement

0.15.0

🐞 Bug fixes

• Fixed resolving images from registries where one variant contains the same layer multiple times by duplicating these files

0.14.0

🌟 Features

• Added OciExtension.imagesTaskClass and pushSingleTaskClass to avoid importing task classes in build scripts
• Enable registry content filtering without the need to access the underlying repository:
  • Added OciRegistries.exclusiveContent(Action<in InclusiveRepositoryContentDescriptor>)
  • Added OciRegistry.content(Action<in RepositoryContentDescriptor>)

🐞 Bug fixes

• Fixed resolving images from an empty configuration
• Fixed resolving images where one variant contains the same layer artifact file multiple times

0.13.0

🌟 Features

• Support the GitHub Container Registry
  • Add OciRegistries.gitHubContainerRegistry {} convenience function
  • Support registry tokens that are not JWTs
  • Remove authentication challenge validation because the GitHub Container Registry creates unexpected authentication challenges

✨ Improvements

• Support duplicate manifest descriptors in image index

0.12.0

🐞 Bug fixes

• Fixed resolving image inputs where 2 (or more) variants share the same layer artifact file

ℹ️ Miscellaneous

• Updated dependencies

0.11.0

🌟 Features

• Fine-grained variants for each platform (more detailed information will be added later)
• Enable selection of a subset of platforms via PlatformSelector
• Allow configuring the same layer via multiple scopes (allPlatforms, platformsMatching, specificPlatform)

✨ Improvements

• Improved handling of unexpected manifest, config and layer media types by filtering out the corresponding image (that is actually not a real container image, rather a different artifact)
• Improved registry URL encoding/escaping in repository URL for better readability

🐞 Bug fixes

• Fixed delayed creation of the destination directory of an OciCopySpec

ℹ️ Miscellaneous

• Updated dependencies

0.10.0

🌟 Features

• Enable reuse of OciCopySpec similar to org.gradle.api.file.CopySpec
  • Added OciExtension.copySpec() and OciExtension.copySpec(Action<in OciCopySpec>) factory methods
  • Added OciCopySpec.with(OciCopySpec)
• New features for layer creation in OciLayerTask:
  • Enable configuration of digest algorithm via digestAlgorithm property of type OciDigestAlgorithm with options SHA_256 (default) and SHA_512
  • Enable configuration of layer compression via compression property of type OciLayerCompression with options NONE and GZIP (default)
  • Added mediaType provider of type String derived from compression
  • Added extension property of type String with convention derived from compression (tar for NONE, tgz for GZIP)
  • Replaced digestFile with digest provider of type OciDigest
  • Replaced diffIdFile with diffId provider of type OciDigest
  • Added size provider of type Long
• Enable access to the org.gradle.api.artifacts.Configuration that belongs to an image definition via OciImageDefinition.configuration
• Enable use of providers for capabilities via OciImageDefinition.Capabilities.add(Provider<String>)

✨ Improvements

• More robust detection of component and layer files in resolved OCI image dependencies
  • Allows different layer artifacts with the same digest
  • Allows different variants to reference the same layer artifact
• Added normalization of some platform variants to support images produced with containerd normalization (related issue: docker-library/official-images#16859):
  • The default variant for the architecture arm64 is v8, so for example linux/arm64 is the same as linux/arm64/v8
  • The default variant for the architecture arm is v7, so for example linux/arm is the same as linux/arm/v7
• The destination directory of an OciCopySpec is only created if there are source files
• Simplified build output of layers
  • Removed one subfolder level: oci/images/$imageDefName/$layerName => oci/images/$imageDefName
  • Replaced .diffId and .digest files with a single .properties file
• Improved naming of layers downloaded from a registry
  • Include the layer digest (truncated) into the filename instead of a counter so the name is not dependent on the order of layers
  • Include file extension derived from the media type
• Transformation of image from a registry to an OCI component is now also deterministic in the edge case of duplicate platforms in the image index
• Renamed OciLayerTask.tarFile to file
• Renamed OciComponentTask.componentFile to file
• Renamed OciDigestAlgorithm.ociPrefix to id
• Renamed OciDigestAlgorithm.algorithmName to standardName

🐞 Bug fixes

• The default capability for image definitions with a name other than main is now added to the Gradle configuration and not only to the OCI component
