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-rc0")
# 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 = "79e7f80df2840d14d7bc79099b5ed4553398cce8cff1f0df97289a07f7fd213c",
    strip_prefix = "rules_oci-2.0.0-rc0",
    url = "https://github.com/bazel-contrib/rules_oci/releases/download/v2.0.0-rc0/rules_oci-v2.0.0-rc0.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#extension or tar#compress attribute to compress the layers beforehand.
# For pkg_tar
pkg_tar(
  extension = "tar.gz"
)

# For tar
tar(
   compress = "gzip"
)
  • 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
  • oci_tarball is renamed to oci_load to better reflect it's purpose.
  • Bazel 5 is no longer supported, and tested by the CI, we will not be accepting fixes for it.

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

API Removals

  • oci_pull no longer has a config_path attribute, use config attribute instead. It was deprecated in 1.x.
