How can I pass --from-platforms using plain Jib CLI?

[artemptushkin]

In Gradle it's possible:

./gradlew -Djib.from.platforms="linux/amd64,linux/arm64"

But when I use CLI (I really use CLI in one of the projects):

jib ... --from-platforms="linux/amd64,linux/arm64"

this fails with

Unknown option: '--from-platforms=linux/amd64,linux/arm64'
Possible solutions: --from-credential-helper, --from-username, --from-password, --from

Looking at CommonContainerConfigCliOptions, jib-cli doesn't seem to have a command-line parameter for it.

Unfortunately, the only workaround I can think of is to use the jib build command and specify platforms in jib.yaml.

from:
  image: "ubuntu"
  # set platforms for multi architecture builds, defaults to `linux/amd64`
  platforms:
    - architecture: "arm"
      os: "linux"
    - architecture: "amd64"
      os: "darwin"

@chanseokoh thank you for the quick response, I thought so according to the documentation, and I will try the yaml approach. I will close the issue with this resolution, but I have just a question maybe you know

Do you have any defaults in jib.yaml to set? Let's say I have my CLI command with N parameters, if I set all of them as yaml fields will it be enough, or should I default something else? I could reverse but frankly, I don't have time for this

[artemptushkin]

I just realized that I use jar command and not build and the first doesn't support the jib.yaml file. So I have to either use build command or get back to the Gradle plugin here

@chanseokoh can we implement a feature in the scope of this issue to pass platforms from the CLI parameters? I see it's possible, we can replace here emptySet with a parameter
