Compiled kotlin with cli with docker and created an environment that can be executed with java

I wanted to study kotlin for the first time, but I didn't like to have the kotlin compiler on my mac, so I made a set with docker compose. I do not assume that I will use a build tool, but I created it based on the concept of preparing an environment where you can check while running the simple grammar of kotlin. If you need it, please refer to it.

What was made

./docker-compose.yml

version: "3.7"

services: 
  java:
    build: ./docker/java
    tty: true
    volumes:
      - ./src:/usr/local/src

./docker/java/Dockerfile

FROM openjdk:13-slim

RUN apt-get update && apt-get install -y git \
    unzip \
    zip \
    curl \
    vim
    
WORKDIR /usr/local/src
RUN curl -s https://get.sdkman.io | bash 
RUN /bin/bash -l -c "chmod a+x $HOME/.sdkman/bin/sdkman-init.sh;$HOME/.sdkman/bin/sdkman-init.sh;sdk install kotlin"

CMD ["/bin/bash"]

The directory structure is as follows

.
├── docker
│   └── java
│       └── Dockerfile
├── docker-compose.yml
└── src
    └── test.kt

How to use

Preparation

Just run the following command in the directory where docker-compose.yml is located.

$ docker-compose build
$ docker-compose up

Move

In fact, compile test.kt and run it with the java command. The target to compile is ./src/test.kt.

fun main(args: Array<String>) {
    println("Hello, World!")
}

Enter the container, compile and run.

$ docker-compose exec java bash
root@3b62768acd0b:/usr/local/src# kotlinc test.kt -include-runtime -d test.jar
OpenJDK 64-Bit Server VM warning: Options -Xverify:none and -noverify were deprecated in JDK 13 and will likely be removed in a future release.
root@3b62768acd0b:/usr/local/src# java -jar test.jar
Hello, World!
root@3b62768acd0b:/usr/local/src#

I get a warning that -Xverify: none is useless, but I was able to compile and execute it with the java command.

Furthermore, since / usr / local / src is volume-mounted, the jar file created after compilation can also be confirmed on the file system of the host machine.

at the end

As you continue to study, you may want to use the build tool or have various inconveniences, but once the environment is in place, I want to study more and more!
