    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?

    Hi, I created a springboot war in such a way it is also possible to run it using java -jar. Is it now possible to create a jib image that doesn't use an application server? I have the war plugin enabled.

    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.

    When I rebuild my project without making any code changes I'm ending up with a new digest for the created OCI with jib - my base image has a digest rather than tag so that shouldn't be it -- what else should I check?

    Hi, is it possible to extend jibdockerbuild task such as task customtask(type: DockerBuildTask) etc.
    this works fine if anyone needs it. if you have better solution please let me know.

    Hi folks,

    Is there anyway I can make Jib preserve the timestamps of files when I add layers?
    The reason I am interested in this is because I am trying to automate the generation of AppCDS (Application Class Data Sharing) in Quarkus when a container image build is requested via Jib.
    Everything works fine until the point where the JDK checks the timestamps of the jars are on the classpath (to ensure that what is in the shared archive matches what is on the supplied runtime classpath) at which point it fails - because the timestamps of the jars have changed when they were added to the layer.

    Is there anything that can be done on the Jib side?
    Just as a note, we use Jib core directly in Quarkus, so I can change how we interact with Jib at will - we don't use the Maven or Gradle plugins.

    Hi, I'm new to jib. I've worked out how most of it. I was getting a decent sized docker spring boot image with java 11.. about 218 mg. I then tested with amazon corretto 11, because that's what i'll need to use, and ended up with an image over 500 mg! The project is new, so all i have is the main spring boot class. Has anyone had luck with corretto ?

    Hi, anywhere I can see the latest version of jib-gradle-plugin that can be used with gradle 4.10.3? As of now I am prevented from upgrading from gradle 4.10.3 but I would still like to test out jib-gradle-plugin. I have read: https://github.com/GoogleContainerTools/jib/tree/master/jib-gradle-plugin which says '2.7.1' requires at least gradle 5.1 but are the some docs where I can see the latest jib-gradle-plugin version for gradle 4.10.3? UPDATE: Through some trial and error I got it to work with "gradle.plugin.com.google.cloud.tools:jib-gradle-plugin:1.8.0" as the latest. But still interested in any docs with compatible versions - if exists.

    Hi @All

    I am new to the maven Jib plugin and is there a way to copy the custom file locations to the container.
    ie. my build files (npm) are in project_base/build and index.html in project_base which I should copy to the container. Any help would be helpful.

    Hi all,
    Ed Randall
    I recently optimised our (maven) Jib build using the JibLayerFilterExtension
    With the help of "dive" (wagoodman/dive) I've been further investigating optimising the image; Is there any way to divert files into the existing layers which Jib already creates? To do that I'd need to know the magic textual names for those layers, and use the same name in the layer filter rule I suppose.
    Also, is there a way to control the order of the layers, so I can put my filtered files underneath the application code? The filtered layers seem to be in declaration order, with the last one at the top of the stack (if base-image is at the conceptual bottom)

    Hi! Thanks for the great work with Jib. I'm creating a deployment in kubernetes and need some data in the container. The way I've used with other images is kubectl cp <file-spec-src> <file-spec-dest>, being <file-spec-dest> the pod with the container where I need the data. As the kubernetes documentation explains: "Requires that the 'tar' binary is present in your container # image. If 'tar' is not present, 'kubectl cp' will fail". In fact, if I run that command in a pod with a jib container, it fails: "OCI runtime exec failed: exec failed: container_linux.go:349: starting container process caused "exec: \"tar\": executable file not found in $PATH": unknown". Is there any workaround/configuration for such cases? Thanks a lot

    Hi, It looks like jib doesn't allow pushing to two different registries as part of a single build: GoogleContainerTools/jib#2299
    The solution mentioned there is to parameterize jib.to.image. Doesn't that create two different sha digests for the two builds? I wonder if there are any issues with that. Is there a way to ensure that the same image is pushed to both registries with the same digest? Thank you!

    @all Jib CLI 0.5.0 has been released!
    Major Changes:
    • Fixed an issue where critical error messages (for example, unauthorized access from a registry) were erased by progress reporting and not shown. (GoogleContainerTools/jib#3148)
    • [Starting with jib-cli 0.4.0] Added support for configuring registry mirrors for base images. This is useful when hitting Docker Hub rate limits. Only public mirrors (such as mirror.gcr.io) are supported. (GoogleContainerTools/jib#3134)
      See CHANGELOG.md for more details.

    Hi everyone! Quick question about the volumes, ownership, and non-root users: we currently build our images manually and would like to migrate to Jib. However, one requirement is that the image can be run as non-root (e.g. on Openshift). Since our application is stateful, we typically just mount a volume to a /data folder, where the non-root user needs write access. I'm trying to figure out how to make this happen with Jib.

    I just realized that the base image for java projects has been changed from distroless to adoptopenjdk.


    But is not clear to me the reason,

    is it distroless deprecated?
    is it distroless discouraged to use?
