Documentation of local_image_targets unclear

[iursino]

What exactly do we put int local_image_targets?

My file is like this:

fake_cloudflare_api/BUILD

load("@rules_kotlin//kotlin:jvm.bzl", "kt_jvm_library")
load("@rules_java//java:defs.bzl", "java_binary")
load("@rules_oci//oci:defs.bzl", "oci_image", "oci_load")
load("@rules_pkg//pkg:tar.bzl", "pkg_tar")
load("@rules_docker_compose_test//docker_compose_test:docker_compose_test.bzl", "docker_compose_test")

kt_jvm_library(
    name = "fake_cloudflare_api",
    srcs = ["Main.kt"],
)

java_binary(
    name = "bin",
    main_class = "iursino.ddnsdaemon.bin.testing.fakecloudflareapi.MainKt",
    runtime_deps = [
        ":fake_cloudflare_api"
    ]
)

pkg_tar(
    name = "jar_layer",
    srcs = [":bin_deploy.jar"],
)

oci_image(
    name = "image",
    base = "@distroless_java",
    entrypoint = [
        "java",
        "-jar",
        "/bin_deploy.jar"
    ],
    tars = [
        ":jar_layer"
    ]
)

oci_load(
    name = "load_image",
    image = ":image",
    repo_tags = ["fake_cloudflare_api:latest"]
)

sh_binary(
    name = "docker_image_fixture",
    srcs = [":load_image"],
)

filegroup(
    name = "tarball.tar",
    visibility = ["//src/lib/adapters/cloudflare_client:__subpackages__"],
    srcs = [
            ":load_image",
            ],
    output_group = "tarball"
)

docker_compose_test(
    name = "medium_test",
    docker_compose_file = ":test-docker-compose.yml",
    docker_compose_test_container = "sut_container",
    local_image_targets = "fake_cloudflare_api:load_image",
    data = [":docker_image_fixture"],
)

But I get "no install script present for fake_cloudflare_api/load_image" when I run bazel test //src/bin/testing/fake_cloudflare_api:medium_test

Note if I run bazel cquery --output=files //src/bin/testing/fake_cloudflare_api:docker_image_fixture I get

bazel-out/k8-fastbuild/bin/src/bin/testing/fake_cloudflare_api/load_image.sh
bazel-out/k8-fastbuild/bin/src/bin/testing/fake_cloudflare_api/docker_image_fixture

Hi @iursino, it looks like you're hitting this point - https://github.com/salesforce/rules_docker_compose_test/blob/main/docker_compose_test/docker_compose_test.sh#L21-L29.

The : in local_image_targets is replaced with /.

Could you share the directory structure of your project? For me, it looks like fake_cloudflare_api dir is not at the root of your project which would cause this problem. local_image_targets needs to be the absolute path to the oci_load target. From your query, the answer to that may be src/bin/testing/fake_cloudflare_api:load_image. You're right, our docs could be clearer on this.

You're right that fixes it, but what I still can't figure out is how to use multiple images, say, one as the sut and one as the test.

Edit: nvm I was having a different problem I was just confused.
