serandel / kscript-docker

Docker image to run kscript (Kotlin scripting)

kscript-docker

Docker image to run kscript (Kotlin scripting) without needing to install it.

The image is labelled with the same version number as kscript, with the underlying dependencies as updated as possible.

The base image is Ubuntu, with Java, Maven, Kotlin and kscript installed with SDKMAN!.

Usage with inline code

docker run -i serandel/kscript 'println("Hello, world!")'

Usage with a script from outside the container

docker run -i serandel/kscript - < script.kts

This will make kscript read the code from stdin while piping the file. Be aware that the -i flag is needed to have stdout redirected outside the container. --rm is just to stop polluting Docker with stopped containers.

Volume

It's highly advisable to create a volume for /root/.kscript so the JARs are cached between different invocations to containers.

docker run -i --rm -v kscript:/root/.kscript serandel/kscript 'println("Hello, world!")'

There is a kscript.sh Bash shell script that invokes the container with these arguments for your convenience.

kscript-docker's Issues

Update please?

I was having problems with the @file:DependsOn style annotations complaining with

[kscript] Resolving dependencies...
[kscript]     Resolving de.mpicbg.scicomp:kutils:0.4...[kscript] [ERROR] Failed to lookup dependencies. Check dependency locators or file a bug on https://github.com/holgerbrandl/kscript
[kscript] [ERROR] Exception: org.sonatype.aether.resolution.DependencyResolutionException: failed to load 'de.mpicbg.scicomp:kutils:jar:0.4 (compile)' from ["jcenter (http://jcenter.bintray.com/, releases+snapshots) without authentication"] into /root/.m2/repository

I updated:

1. Ubuntu to eoan (because Cosmic has moved to old-releases)
2. Java to 8.0.232.fx-zulu (because 8.0.202-zulu has vanished)
3. Kotlin to 1.4.0 (just... uh, because), and
4. kscript to 2.9.3 (because I assumed the latest would have a fix for the main issue)

... and the problem is fixed for me.

Maybe you could update? Your container is the first hit I get in Google.
