Official Docker image for Clojure

docker-clojure

This is the repository for the official Docker image for Clojure. It is automatically pulled and built by Stackbrew into the Docker registry. This image runs on OpenJDK 8 and includes Leiningen.

Examples

Interactive Shell

Run an interactive shell from this image.

docker run -i -t clojure /bin/bash

Then within the shell, create a new Leiningen project and start a Clojure REPL.

lein new hello-world
cd hello-world
lein repl

clojure:onbuild

This image makes building derivative images easier. For most use cases, creating a Dockerfile in the base of your project directory with the line FROM clojure:onbuild will be enough to create a stand-alone image for your project.

Pull or build this image

docker build --rm -t clojure:onbuild onbuild

Create a Dockerfile in your Clojure app project

FROM clojure:onbuild
CMD ["lein", "run"]

Put this file in the root of your app.

This image includes multiple ONBUILD triggers which should be all you need to bootstrap most applications. The build will COPY . /usr/src/app and RUN lein deps

You can then build and run the CLojure image:

docker build -t my-clojure-app .
docker run -it --rm --name running-clojure-app my-clojure-app
