Docker build context (build/docker dir) about gradle-docker

[uschi2000]

Can you provide a minimal repo (or maybe just test case) that shows the error?

Got the same issue - build/docker contains the whole project after running "gradle docker".
There is no error per - se. It is just that the folder is huge and building it takes time (copying files over).

I think I have found a workaround. I am overriding another docker step - dockerPrepare - preparing the 'build/docker' folder explicitly. I need only a single fatJar in addition to the Dockerfile.

task dockerCopy(type: MoveTo, dependsOn: dockerPrepare) {
    from('build/packed') {
        include "${jarFullName}"
    }
    into 'build/docker'
}

docker {
    name "${dockerImageName}"

    dockerfile 'src/main/docker/Dockerfile'
    files 'src/main/docker/Dockerfile'
}

By explicitly setting "files" in docker section I avoid copying everything else. And the custom dockerPrepare step copies over the required file.

Hope that helps.

task dockerCopy(type: MoveTo, dependsOn: dockerPrepare) {
    from('build/libs') {
        include "*.jar"
    }
    into "build/docker"
}

results in

FAILURE: Build failed with an exception.

What is "MoveTo"?
