rules_containers_util

A set of rules to operate on container images, such as extracting files or directories from a container image and making them available to Bazel actions.

Installation

Add to your MODULE.bazel:

bazel_dep(name = "rules_containers_util", version = "0.0.1")

Note

Until a new release of rules_img containing flatten-image is published to the Bazel Central Registry (BCR), configure the rules_img pre-release registry in your .bazelrc:

common --registry=https://bazel-contrib.github.io/rules_img --registry=https://bcr.bazel.build

Usage

Extract a file or directory

load("@rules_containers_util//containers:defs.bzl", "image_extract")

# Extract a single file
image_extract(
    name = "extracted_tool",
    file = "/usr/local/bin/tool",
    image = ":my_image",
)

# Extract a directory
image_extract(
    name = "extracted_data",
    directory = "/opt/data",
    image = ":my_image",
)

# Extract multiple files
image_extract(
    name = "extracted_files",
    files = {
        "/etc/app/config.txt": "config.txt",
        "/usr/local/bin/helper": "helper",
    },
    image = ":my_image",
)
