    # "Hello, world" in Clojure compiled with GrallVM running in Docker

    Create a new minimal Clojure project using leiningen:

    ```
    $ lein new minimal hello
    $ cd hello
    ```

    Edit `project.clj` to look like this:

    ```clojure
    (defproject hello "0.1.0-SNAPSHOT"
    :dependencies [[org.clojure/clojure "1.10.0"]]
    :profiles {:dev {:dependencies [[org.clojure/test.check "0.9.0"]]}} :main hello.core)
    ```

    Edit `src/hello/core.clj` to look like this:

    ```clojure
    (ns hello.core
    (:gen-class))

    (defn -main []
    (println "Hello, clombda!"))
    ```

    According to [this](https://github.com/uwcpdx/clombda/blob/master/README.md) you also need to run this:

    ```
    $ lein change :main set hello.core
    ```

    Build a native image:

    ```
    $ docker run --rm "-v$(pwd):/clj" "-v${HOME}/.m2:/root/.m2" spieden/clombda:latest
    ```

    Create a Dockerfile:

    ```
    FROM renanpalmeira/graalvm-alpine
    COPY target/clombda/package/clj-native /root/
    CMD ["/root/clj-native"]
    ```

    Build a docker image:

    ```
    $ docker build -t hello .
    ```

    Run it:

    ```
    $ docker run hello
    Hello, clombda!
    ```
