您可以将Paketo image-labels buildpack与Heroku构建包一起使用。下面是一个从pack CLI执行此操作的示例：

$ pack build --builder heroku/buildpacks:20 --buildpack paketo-buildpacks/image-labels my-app

使用CLI，您可以根据需要添加更多的--buildpack选项。
如果您想对此进行编码，您可以创建一个project.toml，并使用io.buildpacks.post.group始终在最后运行image-labels构建包。
如果您使用的是creator二进制文件，则可以为它提供group.toml https://github.com/buildpacks/spec/blob/main/platform.md#inputs-3

以下是如何实现这一目标的更详细答案：
1.创建自定义构建器映像，其中包含heroku构建包以及所需的映像标签buildpack by paketo
1.按指定顺序手动运行生命周期可执行文件
1.将图像标签buildpack的条目添加到组。toml检测器运行后
下面是一个构建自定义构建器映像的Dockerfile示例：

# paketo
FROM paketobuildpacks/builder:base as paketo

# heroku
FROM heroku/builder-classic:22

USER root

COPY --from=paketo /cnb/buildpacks/paketo-buildpacks_image-labels /cnb/buildpacks/paketo-buildpacks_image-labels

COPY group.toml /opt/group.toml

SHELL ["/bin/bash", "-c"]

USER 1000

/opt/group.toml下的文件如下所示：

[[group]]
    description = "A Cloud Native Buildpack that enables configuration of labels on the created image"
    homepage = "https://github.com/paketo-buildpacks/image-labels"
    id = "paketo-buildpacks/image-labels"
    keywords = ["image-labels", "labels"]
    name = "Paketo Image Labels Buildpack"
    version = "4.2.0"
    sbom-formats = ["application/vnd.cyclonedx+json", "application/vnd.syft+json"]
    api = "0.7"

然后，您可以按如下方式运行生命周期：

export CNB_LAYERS_DIR=${BP_LAYERS_PATH}
export CNB_GROUP_PATH=${BP_LAYERS_PATH}/group.toml

/cnb/lifecycle/detector -layers=${BP_LAYERS_PATH} -platform=${BP_PLATFORM_PATH} -app=.

# add additional logic for image-label-buildpack
[ -f /opt/group.toml ] && echo "$(cat /opt/group.toml)" >> ${CNB_GROUP_PATH}

export BP_LAST_VERSION=${BP_IMAGE_VERSION}
/cnb/lifecycle/analyzer -uid=$(id -u) -gid=0 -cache-dir=${BP_CACHE_PATH} -layers=${BP_LAYERS_PATH} -analyzed=${BP_LAYERS_PATH}/analyzed.toml ${BP_REGISTRY}/${BP_IMAGE_NAME}:${BP_LAST_VERSION}

/cnb/lifecycle/restorer -uid=$(id -u) -gid=0 -cache-dir=${BP_CACHE_PATH} -layers=${BP_LAYERS_PATH} -group=${BP_LAYERS_PATH}/group.toml

/cnb/lifecycle/builder -layers=${BP_LAYERS_PATH} -platform=${BP_PLATFORM_PATH} -app=. -group=${BP_LAYERS_PATH}/group.toml

/cnb/lifecycle/exporter -uid=$(id -u) -gid=0 -cache-dir=${BP_CACHE_PATH} -layers=${BP_LAYERS_PATH} -app=. -analyzed=${BP_LAYERS_PATH}/analyzed.toml -run-image=${BP_RUN_IMAGE} ${BP_REGISTRY}/${BP_IMAGE_NAME}:${BP_IMAGE_VERSION}

请确保使用platform spec定义的正常值填充env变量。
