How to use the container-images extension to add custom labels to an image

[etsauer]

I've got an app created with:

quarkus create app org.acme:kubernetes-quickstart \
    --extension='resteasy-reactive,kubernetes,jib'

Following this guide:

https://quarkus.io/guides/container-image

I'm building my app and pushing my container image with the following command:

quarkus build -Dquarkus.container-image.build=true --native

I am trying to figure out how to add a custom label to the resulting image. I've tried using the property (documented below) as follows:

quarkus.container-image.labels=io.openshift.build.commit.id=bc0ec63a3b1f053fc95dd2f037958c84866773b8

https://quarkus.io/guides/container-image#quarkus-container-image_quarkus.container-image.labels-labels

When I build I see this warning in the build log:

[WARNING] [io.quarkus.config] Unrecognized configuration key "quarkus.container-image.labels" was provided; it will be ignored; verify that the dependency extension for this configuration is set or that you did not make a typo

And as a result, I do not see my custom label when i inspect the built image:

$ podman images 6e3936b572d9 --format json | jq .[0].Labels
{
  "architecture": "x86_64",
  "build-date": "2023-09-13T15:45:34",

  "vcs-type": "git",
  "vendor": "Red Hat, Inc.",
  "version": "8.8"
}

Did I miss a step?

You would use it like so:

quarkus.container-image.labels."io.openshift.build.commit.id"=bc0ec63a3b1f053fc95dd2f037958c84866773b8
