polylith example

This fork of clojure-polylith-realworld-example-app has a new project that uses jib to package the realworld-backend into a container image. There is an additional directory at projects/realworld-backend-jib which demonstrates this packaging.

cd projects/realworld-backend-jib
clj -T:jib build

This is configured to build an image to a local docker daemon (tagged with realworld-backend:latest).

Start up the server using the following command.

docker run --rm -p 6003:6003 realworld-backend

We could not use the existing project at projects/realworld-backend/deps.edn. This project was designed to run the server in the repl, and uses the furkan3ayraktar/polylith-clj-deps-ring library, which builds a classloader suitable for running a polylith app in a repl, but this entrypoint is not ideal for a container process.
