Hi, just encountered this and it is still broken. @mpeddada1 here is the reproducer Given a sample Gradle application generated with plugins {
id 'application'
id 'com.google.cloud.tools.jib' version '3.4.2'
}
repositories {
mavenCentral()
}
dependencies {
testImplementation libs.junit.jupiter
testRuntimeOnly 'org.junit.platform:junit-platform-launcher'
implementation libs.guava
}
java {
toolchain {
languageVersion = JavaLanguageVersion.of(21)
}
}
application {
mainClass = 'org.example.App'
}
tasks.named('test') {
useJUnitPlatform()
}
jib {
from {
image = 'docker://jib-podman-test-base'
}
to {
image = 'jib-podman-test'
}
}
tasks.named('jibDockerBuild').configure {
doFirst {
exec {
workingDir project.projectDir
commandLine 'podman', 'build', '-t', 'jib-podman-test-base', '.'
}
}
}And an Then run The problem is that Jib reads the Digest from the wrong place: This is the What you need to read is the This makes jib unusable for this use case on machines with podman only. |

Hm, it seems that docker does not have the Here is the Podman doc for So you could just prepend Also if here: You could somehow detect this and instead of |

Environment:
Description of the issue:
When using a URI like
docker://ubuntu:latestfor the base image, the build fails with the following exception when using podman (v4.7.1) asjib.dockerClient.executable:The problem seems to be that in https://github.com/GoogleContainerTools/jib/blob/440bd4897c6c427cc9a491128aa76c72378d605b/jib-core/src/main/java/com/google/cloud/tools/jib/docker/CliDockerClient.java#L70C17-L70C17 the value of the
"Id"property is used as the "digest". The json output for "inspect" differs slightly between podman and docker:podman inspect -f "{{json .}}" --type image ubuntu:latest:docker inspect -f "{{json .}}" --type image ubuntu:latestSo it seems that in the output of podman we would have to use the value of the "Digest" property instead.
Would you consider adjusting the logic here a bit so that building images from the local cache with podman can also work?
