Hello, Im using jib core to build an image from scratch. e.g.

Jib.fromScratch()
           .addLayer(Arrays.asList(Paths.get("helloworld.sh")), AbsoluteUnixPath.get("/")) 
           .setEntrypoint("sh", "/helloworld.sh")
           .containerize(
               Containerizer.to(RegistryImage.named("hello-from-jib")
                                             .addCredential(args[0], args[1])));

I need the image to have a different architecture and os than the defaults of amd64 and linux. I can't find any methods to set these. Is there a way that Im failing to see? Thanks

Hi all, I'm wondering if anyone has confirmed that the jib-gradle-plugin actually works when building a non-linux/amd64 image?

from {
        image = "amazoncorretto:11"
        platforms {
            platform {
                architecture = 'arm64'
                os = 'linux'
            }
        }
    }

> multi-platform image building is not yet supported

https://github.com/GoogleContainerTools/jib/blob/master/jib-gradle-plugin/src/main/java/com/google/cloud/tools/jib/gradle/PlatformParametersSpec.java#L45 seems to add to a collection but https://github.com/GoogleContainerTools/jib/blob/master/jib-core/src/main/java/com/google/cloud/tools/jib/api/JibContainerBuilder.java#L597 requires exactly 1 platform in the collection.

The gradle plugin docs implies that more than 1 platform is permitted, but that is clearly not the case, so I'm wondering if this a disconnect between the two "teams".

Chanseok Oh

@chanseokoh

@jtgasper3 multi-platform image building is currently blocked until we sort out some lingering issues. However, your configuration should work, since you are defining only one platform. So I don't get how you are hitting the error.

Let me try to reproduce this locally.

I can reproduce this. It's a bug. The config currently results in two platforms "amd64" and "arm64". So that's why you're getting the error.

@jtgasper3

Thanks for confirming. I'm not a gradle internals dev, but I'm assuming this gets invoked regardless of if I try to override it in the config or not: https://github.com/GoogleContainerTools/jib/blob/master/jib-gradle-plugin/src/main/java/com/google/cloud/tools/jib/gradle/BaseImageParameters.java#L48

Hi! I'm new not Jib and google cloud. I'm following the getting started guide here https://cloud.google.com/java/getting-started it asks me to

"Build the image using Jib:
mvn package jib:build -Dimage gcr.io/PROJECT_ID/bookshelf
Replace PROJECT_ID with the Google Cloud project ID that you created."

however, I get the error "[ERROR] Unknown lifecycle phase "gcr.io/getting-started-292422/bookshelf.... [more stuff] ".

Can anyone point me in the right direction of the place to ask questions to someone who can help me understand this? Thanks! :)

Hi, probably asked many times... We have container that is created with jib which is spring boot java application. This is working perfectly. But now, we need to create another container that will execute database migration as job before deployment (as helm hook). For that I'd like to exclude all java stuff from that container to have it smaller and extend the liquibase image. Is it possible to exclude everything that is being included in /app folder inide container? This is wat I have so far

Chanseok Oh

@chanseokoh

@bilak from what I understand, Jib isn't designed for your use case (it's for containerizing Java apps as part of Maven builds). However, Jib has an extension mechanism, and we have a Jib Layer-Filter extension, with which you can remove files. (But you need to understand your workflow is not what Jib is intended for.)

Lukáš Vasek

@bilak

@chanseokoh I understand, but it would be very usefull if it basically suports this. Nowadays when there is kubernetes around each corner and we are building a lot of containers (not just java) this would be super helpful

Chanseok Oh

@chanseokoh

For the workflow like this, I think Jib CLI which we are working on releasing by EOY may be a better fit. Jib CLI is a general image building tool you can run on the command-line. But for now, perhaps you can use the extension if you want.

Lukáš Vasek

@bilak

Ok thank you very much, I'll try and come back later if I find some issue. Btw would there be also some maven wrapper for jib cli?

Chanseok Oh

@chanseokoh

I don't think we'll have any wrapper around Jib CLI. Maybe Maven already has a plugin to run an arbitrary process?

Lukáš Vasek

@bilak

@chanseokoh this works. Thanks!

Can anyone help me with examples of a Spring Boot Maven WAR built and deployed to an image, running in embedded Tomcat (or non-embedded if that's better). I've been trying for days and getting loads of errors getting it running in docker, and I'm not finding much guidance on stack overflow. BTW, seen this already. Can't get any combination of things to work. Any help would be hugely appreciated.

Chanseok Oh

@chanseokoh

@icewhite I strongly recommend going for non-WAR (hence running in embedded Tomcat or Jetty). WAR is like a legacy app in the days resources were expensive where you needed to run multiple WARs on a single application server. The model doesn't fit well with containers these days. Just remove <packaging>war from pom.xml and switch it to a JAR project.

Hey hey :wave:
We're using jib to containerize our apps and I just realized that using jib with gradle doesn't execute tasks that are not default(compileJava, classes, jar, jib). Is that right? Because gradle jib doesn't fail when tests are failing. Do I need to run gradle build before I use gradle jib to make sure that tests succeed?
I couldn't see anything like this and I wanted to confirm.

Hello, what about multistep build ...is that somehow possible with jib? I'm looking into openj9 and it's class sharing but that would require me to use openj9 on each developer machine or do some multistep build. I would rather use multi step, but don't think that's supported by jib currently. Is it?

@/all Jib 2.7.0 has been released!

Major Changes

Added an option jib.container.expandClasspathDependencies to preserve the order of loading dependencies as configured in a project. The option enumerates dependency JARs instead of using a wildcard (/app/libs/*) in the Java runtime classpath for an image entrypoint. (GoogleContainerTools/jib#1871, GoogleContainerTools/jib#1907, GoogleContainerTools/jib#2228, GoogleContainerTools/jib#2733)
- The option is also useful for AppCDS. (GoogleContainerTools/jib#2471)
- Turning on the option may result in a very long classpath string, and the OS may not support passing such a long string to JVM.
  (Gradle) - Added lazy evaluation for jib.(to|from).auth.(username|password) and jib.from.image using Gradle Property and Provider. (GoogleContainerTools/jib#2905)
Fixed NullPointerException when pulling an OCI base image whose manifest does not have mediaType information. (GoogleContainerTools/jib#2819)
Fixed build failure when using a Docker daemon base image (docker://...) that has duplicate layers. (GoogleContainerTools/jib#2829)

See CHANGELOG.md (Maven / Gradle) for more details.

Hi, I have a multi-module Gradle project written in Kotlin using Spring Boot. Is there a feasible way how to build a single Docker image using Jib?
I saw a multi-module example but it creates several images which is not what I want. I have Spring Boot application (usually run as java -jar myApp.jar), divided into Gradle subprojects for better maintainability, but it is still a single app that needs to be in a single container, not separate microservices. Thanks for all hints.
