v2.0.0-beta1

Using bzlmod with Bazel 6 or later:

1. Add common --enable_bzlmod to .bazelrc.

2. Add to your MODULE.bazel file:

bazel_dep(name = "rules_oci", version = "2.0.0-beta1")
# For testing, we also recommend https://registry.bazel.build/modules/container_structure_test

oci = use_extension("@rules_oci//oci:extensions.bzl", "oci")

# Declare external images you need to pull, for example: 
oci.pull(
    name = "distroless_base",
    # 'latest' is not reproducible, but it's convenient.
    # During the build we print a WARNING message that includes recommended 'digest' and 'platforms'
    # values which you can use here in place of 'tag' to pin for reproducibility.
    tag = "latest",
    image = "gcr.io/distroless/base",
    platforms = ["linux/amd64"],
)

# For each oci.pull call, repeat the "name" here to expose them as dependencies.
use_repo(oci, "distroless_base")

Using WORKSPACE:

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "rules_oci",
    sha256 = "f70f07f9d0d6c275d7ec7d3c7f236d9b552ba3205e8f37df9c1125031cf967cc",
    strip_prefix = "rules_oci-2.0.0-beta1",
    url = "https://github.com/bazel-contrib/rules_oci/releases/download/v2.0.0-beta1/rules_oci-v2.0.0-beta1.tar.gz",
)

load("@rules_oci//oci:dependencies.bzl", "rules_oci_dependencies")

rules_oci_dependencies()

load("@rules_oci//oci:repositories.bzl", "oci_register_toolchains")

oci_register_toolchains(name = "oci")

# You can pull your base images using oci_pull like this:
load("@rules_oci//oci:pull.bzl", "oci_pull")

oci_pull(
    name = "distroless_base",
    digest = "sha256:ccaef5ee2f1850270d453fdf700a5392534f8d1a8ca2acda391fbb6a06b81c86",
    image = "gcr.io/distroless/base",
    platforms = [
        "linux/amd64",
        "linux/arm64",
    ],
)

BREAKING CHANGES

• Uncompressed archives in the tars attribute is no longer compressed when creating the image, this might make images bigger compared to 1.x. Use pkg_tar#compression or tar#compress attribute to compress the layers beforehand.
• Digests of images created 1.x rules_oci will not match 2.x rules_oci, as we are no longer using crane to create the images. However, images should stay the same semantically. You can use diffoci to make sure they are the same semantically!
• Default output of oci_tarball is no longer a tarball, use a filegroup target to get the tarball. See #548
• Bazel 5 is no longer supported.
• oci_tarball is renamed to oci_load to better reflect it's purpose.

SIGNIFICANT CHANGES

• OCIImage action no longer spins an ephemeral registry instance to mutate images locally, making it slightly faster.
• oci_image now supports zstd compression
• Now oci_pull fetches blobs in parallel on Bazel >= 7.1

What's Changed

• fix: propagate transitive inputs by @thesayyn in #646
