docker container rm $(docker container ls -aq)
docker image rm $(docker image ls -aq)

Build in minishift from local source code

oc new-app registry.access.redhat.com/redhat-openjdk-18/openjdk18-openshift~. --name=myapp
oc start-build myapp --from-dir=. --follow
oc expose svc/myapp --port 8080

Build in minishift from remote github source code

oc import-image java:8 --from=registry.access.redhat.com/redhat-openjdk-18/openjdk18-openshift --confirm
oc new-app --name reactive-web "java:8~https://github.com/tradercentric/reactive-web.git"
oc expose svc/reactive-web --port 8080

Oc logs & status & etc.

oc logs -f bc/reactive-web
oc rollout status -w dc/reactive-web
echo http://$(oc get route reactive-web -o jsonpath='{.spec.host}{"\n"}')
oc get all --selector app=reactive-web -o name
oc delete all --selector app=reactive-web
