jibDockerBuild:multi-platform image building not supported when pushing to Docker engine

[machaleb]

Environment:

• com.google.cloud.tools.jib: 3.2.1
• Gradle 7.3.3
• OS: Linux 4.18.0-348.23.1.el8_5.x86_64 amd64
• JVM: 17.0.3 (Azul Systems, Inc. 17.0.3+7-LTS

Description of the issue:
When trying to build multi-arch image for amd64 and s390x platform using jibDockerBuild it gives error as below

* What went wrong:
Execution failed for task ':jibDockerBuild'.
> com.google.cloud.tools.jib.plugins.common.BuildStepsExecutionException: multi-platform image building not supported when pushing to Docker engine

Expected behavior:
It should build the image using command ./gradlew jibDockerBuild

Steps to reproduce:

jib-maven-plugin Configuration:

PASTE YOUR pom.xml CONFIGURATION HERE

jib-gradle-plugin Configuration:

[root@flexible1 helloworld]# cat build.gradle
plugins {
  id 'java'
  id 'com.google.cloud.tools.jib' version '3.2.1'
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
  mavenCentral()
}

dependencies {
  implementation 'com.google.guava:guava:23.6-jre'
}

jib.from {
  image = 'nginx'
  platforms {
    platform {
      architecture = 'amd64'
      os = 'linux'
    }
    platform {
      architecture = 's390x'
      os = 'linux'
    }
  }
}

jib.to {
  image = 'bhagyashrimachale/helloworld:v2'
  auth {
    username = 'bhagyashrimachale'
    password = '*********************'
  }
}

Log output:

Starting a Gradle Daemon (subsequent builds will be faster)

Additional Information:
I am able to build the image using ./gradlew jib but my requirement is to build it using ./gradlew jibDockerBuild

This is a duplicate of #2743. And it's unclear if the Docker daemon supports storing images of different architectures.

@chanseokoh I saw the issue which you referred but it is bit unclear. with docker buildx we can build mutli-platform image using docker buildx build --platform linux/amd64,linux/s390x . How we can do using jibDockerBuild ?
jibDockerBuild is not having same feature as docker buildx?

[chanseokoh]

According to the following comments

• Where did the built multi-platform image go? docker/buildx#166 (comment)
• Where did the built multi-platform image go? docker/buildx#166 (comment)
• Where did the built multi-platform image go? docker/buildx#166 (comment),

docker buildx build --platform (with multiple platforms specified) doesn't seem to support pushing to a Docker engine either, which is the same situation with jibDockerBuild.

And your feature request is #2743, so I assure you this is a dup.

[elefeint]

Closing as duplicate.

[machaleb]

Closing this issue as docker engine doesn't support multiplatform manifest when pushing to it.
@chanseokoh thanks for explanation .

use jib:build instand of jib:dockerBuild

auth

solved it for me. thanks. seems like jibDockerBuild only builds a local docker image out of the spring boot app. but jib builds the image and pushes to docker hub, and also somehow works on multi platform.

[clembo590]

use jib:build instand of jib:dockerBuild

this is not a good option as it will build and push the images

[alexanderankin]

this has been fixed, see #2743 (comment)

in the sense that you can use the jib docker task while multiplatform configuration exists, it picks the correct local platform and uses it.
