OpenShift S2I image for building Clojure projects using 'lein uberjar' and Java11.

Installation to OpenShift 4.8

Login to your OpenShift cluster

oc login

oc new-project clojure-s2i

oc new-build https://github.com/tfriman/s2i-clojure#refreshjvm11 --name s2i-clojure -n clojure-s2i

You can follow the build

oc logs -f bc/s2i-clojure -n s2i-clojure

You need to make this to have s2i to be visible within cluster.

oc tag clojure-s2i/s2i-clojure:latest openshift/s2i-clojure:latest

Usage example

Create a test project

oc new-project clj-test

After the build has finished you can test your new builder:

oc new-build s2i-clojure~https://github.com/tfriman/clj-rest-helloworld#v1.0.0 --name=clj-test

And follow the build

oc logs -f bc/clj-test

After the build has finished create a new app:

oc new-app clj-test

And open the service to the world:

oc expose svc/clj-test

See the url for the application

oc get routes clj-test --template='{{ .spec.host }}'

And open it using your browser.

Making s2i-clojure builder visible to catalog

oc edit is/s2i-clojure -n openshift -o json

Make it look like this:

{
...
	"spec": {
	"tags": [
		{
		...
		"annotations": {
			"openshift.io/display-name": "S2I Clojure",
			"description": "Build and deploy a Clojure app",
			"iconClass": "icon-clojure",
			"sampleRepo": "https://github.com/tfriman/clj-rest-helloworld",
			"sampleRef": "v1.0.0",
			"tags": "builder,clojure",
			"version": "latest",
			"supports": "clojure"
		},
		}
	]
	}
}

Wait for a while to catalog service to catch up and your Clojure S2I builder should appear in the "Import from Git" section.
