What can be the reason?

# server

What can be the reason?

[Andrew O'Hara]

Is libs from settings.gradle.kts via a plugin or dependency catalog? Are you sure that's been imported into your build container?

Personally, I don't build the jar with my Dockerfile; I have my CI container build the jar and then copy it into the production container. So I don't really know what gotchas to expect when doing it this way.

[Sevak Tadevosyan]

I’m new in server side world, have created mobile app with kotlin multiplatform, and decided to crete server app as well. Have done a few things and decided to deploy somewhere(in Render in this case) to test.

[Sevak Tadevosyan]

When I build the server and run everything is ok

[Sevak Tadevosyan]

But when I run the docker file it cant understand version catalog

[Andrew O'Hara]

Where is your version catalog defined? Is it right next to your build.gradle.kts?

[Sevak Tadevosyan]

It is inside ROOT/gradle/

[Andrew O'Hara]

Is that your system root? Or your repository root?

[Sevak Tadevosyan]

Repo root

[Andrew O'Hara]

Hmm, I'm not really sure why it wouldn't get picked up then. 🤷

If it builds right outside of a docker build step check that the docker copy step takes all the files it should and that the right files are copied to the docker context. Check also if the build gradle file is connected to the build in settings.gradle.kts

[Sevak Tadevosyan]

this is my settings.gradle.kts

rootProject.name = "COAF"
enableFeaturePreview("TYPESAFE_PROJECT_ACCESSORS")

pluginManagement {
    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
    }
}

dependencyResolutionManagement {
    repositories {
        google()
        mavenCentral()
    }
}

include(":composeApp")
include(":server")
include(":shared")

[Sevak Tadevosyan]

what files should docker copy?

[Sevak Tadevosyan]

I have done as ktor documentation suggested

[Eivind]

i assume you are using the standar version catalog name libs.versions.toml ?

Can you build it with out docker and it works? gradlew build

[Eivind]

It looks right structure and gradle file

[Eivind]

Im abit unsure about you docker file. In the copy step do you only copy the server in that case you would only have the server and the build file on the route. Disconnected from the rest of the build

[Eivind]

And that would cause the error you have now

[Eivind]

So i think this line is wrong COPY --chown=gradle:gradle server /home/gradle/src

[Eivind]

Change it to copy inn you repo root mybe something like this COPY --chown=gradle:gradle . /home/gradle/src

[Eivind]

The rest of the Gradle stuff looks ok, so Docker problem

[Sevak Tadevosyan]

Thst fixed, thank you very much

[Sevak Tadevosyan]

but now it throws error on last copy:

Check that the path is right now that you are copying form a different structure form the build image. Could also be more specific and copy just the fat jar.

This is a nice tool for inspecting docker files. https://github.com/wagoodman/dive

[Eivind]

I think you can see the name of the build container in you docker file and inspect that one to see how the product is
