k8s:build issue COPY failed: stat #149

Closed zebu closed 4 years ago

zebu commented 4 years ago

I'm seeing an issue building docker images with 1.0.0-alpha-1. The pom + Dockerfile has no issues with fabric8 4.4.1.

[INFO] k8s: ---> d99a48de8998 [INFO] k8s: Step 9/10 : COPY target/my-service.jar my-service.jar [INFO] k8s: [ERROR] k8s: Failed to execute the build [Error while trying to build the image] [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 5.812 s [INFO] Finished at: 2020-04-13T15:23:49-04:00 [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.eclipse.jkube:kubernetes-maven-plugin:1.0.0-alpha-1:build (default-cli) on project my-service: Failed to execute the build: Error while trying to build the image: Unable to build image [myrepo.com:5100/com.xxx.xxxxx.xx/my-service:1.0] : "COPY failed: stat /var/lib/docker/tmp/docker-builder481246942/target/my-service.jar: no such file or directory" -> [Help 1]

Has anyone run across this?

@zebu : ah, Could you please share a sample pom so that we can try to reproduce?

@zebu: strange, I copy-pasted your pom with some modifications in one of my samples but was unable to reproduce this. I'm not sure what's wrong in my reproduced but it was able to build image fine.

zebu commented 4 years ago

I'll build a demo project that demonstrates the issue. Give me a few days

zebu commented 4 years ago

I've written an example project that demonstrates a similar issue but not the exact. https://github.com/zebu/jkube-demo.git

The original issue was stat complaining about a file that did not exist. This issue I'm seeing now is the copy not finding files.

Based on your previous comment maybe this is an environmental issue but these poms are nearly identical.

Hi @zebu,

On Friday we published a quickstart showcasing how to use external Dockerfile for your build.

As of now, one of the required configurations, besides <dockerFile>, is contextDir.

Please, check if updating your affected pom.xml accordingly works.

https://github.com/eclipse/jkube/blob/358da963dcc3f16613833be48946b40b316ebf4c/quickstarts/maven/docker-file-provided/pom.xml#L62-L68

manusa commented 4 years ago

Anyway, we'll do a thorougher check of the current behavior, as it is redundant to specify both properties as they can be inferred from some defaults:

manusa commented 4 years ago

Relates to: https://github.com/fabric8io/fabric8-maven-plugin/issues/1097

manusa commented 4 years ago

HI @zebu,

I'm checking your demo project now with latest release 1.0.0-alpha-3.

Following what's stated in the documentation, your source directory should be changed to /maven unless specified otherwise.

The files of the assembly are stored in a build context relative directory maven/ but can be changed by changing the assembly name with the option in the assembly configuration.

So in order to make your project work you have 2 options:

A. Modify your Dockerfile and change directory from where COPY picks up the files to /maven and leave your pom.xml as it is:

FROM openjdk:15-slim-buster

COPY maven/*.jar application.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-Dspring.profiles.active=st9","-jar","/application.jar"]

B. Modify your pom.xml and provide an <assembly> description and leave your Dockerfile as it is:

<images>
    <image>
        <name>%a:%l</name>
        <build>
            <dockerFile>${project.basedir}/Dockerfile</dockerFile>
            <assembly>
                <name>target</name>
                <dockerFileDir>${project.basedir}</dockerFileDir>
            </assembly>
        </build>
    </image>
</images>

I'm not sure why fabric8_pom.xml works.

zebu commented 4 years ago

thanks, this resolved the issue

yaakov-berkovitch commented 3 years ago

Im using the plugin version 1.1.0 and failed on the same. Also for me fabrik8 plugin works fine. If I add the assembly, i get the error:

[WARNING] k8s: Dockerfile /shared-folders/dev/ms-configuration/ms-configuration/src/main/docker/Dockerfile does not contain an ADD or COPY directive to include assembly created at target. Ignoring assembly.

Also, in this version dockerFileDir tag is not valid.

My Dockerfile looks like:

FROM asms/base-openjdk-openj9-11:latest
ARG JAR_FILE

# Copy the micro-service jar into the image
COPY --chown=afa /maven/${JAR_FILE} /jdk-minimal/application
# Explode the jar
RUN mkdir -p /jdk-minimal/application/exploded && cd /jdk-minimal/application/exploded \
    && jar xvf /jdk-minimal/application/*.jar \
    && cp -r /jdk-minimal/application/exploded/BOOT-INF/lib /jdk-minimal/application/ \
    && cp -r /jdk-minimal/application/exploded/META-INF /jdk-minimal/application/ \
    && cp -r /jdk-minimal/application/exploded/BOOT-INF/classes /jdk-minimal/application/ \
    && rm -rf /jdk-minimal/application/*jar /jdk-minimal/application/exploded

Any idea ?

@yaakov-berkovitch : Hi, Do you have a quick reproducer project which we can try out? I would like to see your assembly configuration XML.

yaakov-berkovitch commented 3 years ago

Thanks @rohanKanojia .

Attached an hello-world project that reproduces the issue. hello-world.zip

Following the output i got:

Thanks a lot, let me try to try it out tomorrow morning.
