This procedure uses OpenShift's source to image workflow and the openjdk18 builder image to push a local jar file into the OpenShift build configuration.
If you don't have the openjdk18 builder image, create the image-stream object I obtained from Thomas's blog post and import it into your project.
oc create -f openjdk-s2i-imagestream.json
If you need an example Spring Boot jar, clone, compile and package the following example.
git clone https://github.com/redhat-helloworld-msa/ola.git
cd ola
mvn clean package
Now create a build config with a binary build strategy and push the jar. If you want to push your own jar, make sure it is located in the target directory.
oc create -f openjdk-s2i-imagestream.json
oc new-build --binary=true --name=ola --image-stream=redhat-openjdk18-openshift
Next, create a deployment config, a service and a route.
oc start-build ola --from-dir=target --follow
oc new-app ola -l app=ola,hystrix.enabled=true
oc expose service ola
Wait for the pod to become ready then test it.
host=`oc get route ola --template={{.spec.host}}`
curl $host/api/health
Optionally, add a readiness probe.
oc env dc/ola AB_ENABLED=jolokia; oc patch dc/ola -p '{"spec":{"template":{"spec":{"containers":[{"name":"ola","ports":[{"containerPort": 8778,"name":"jolokia"}]}]}}}}'
oc set probe dc/ola --readiness --get-url=http://:8080/api/health
