Getting Started

1. Start the application: lein run
2. Go to localhost:8080 to see: Hello World!
3. Read your app's source code at src/clojure_cloud_run/service.clj. Explore the docs of functions that define routes and responses.
4. Run your app's tests with lein test. Read the tests at test/clojure_cloud_run/service_test.clj.
5. Learn more! See the Links section below.

Configuration

To configure logging see config/logback.xml. By default, the app logs to stdout and logs/. To learn more about configuring Logback, read its documentation.

Developing your service

1. Start a new REPL: lein repl
2. Start your service in dev-mode: (def dev-serv (run-dev))
3. Connect your editor to the running REPL session. Re-evaluated code will be seen immediately in the service.

Docker container support

1. Configure your service to accept incoming connections (edit service.clj and add ::http/host "0.0.0.0" )
2. Build an uberjar of your service: lein uberjar
3. Build a Docker image: sudo docker build . -t clojure-cloud-run .
4. Run your Docker image: docker run -p 8080:8080 clojure-cloud-run

OSv unikernel support with Capstan

1. Build and run your image: capstan run -f "8080:8080"

Once the image it built, it's cached. To delete the image and build a new one:

1. capstan rmi clojure-cloud-run; capstan build
