创建project
代码语言：javascript复制$ oc new-project ing-demo
Already on project "ing-demo" on server "https://api.ssli-ocp1.os.fyre.ibm.com:6443".
You can add applications to this project with the 'new-app' command. For example, try:
oc new-app django-psql-example
to build a new example application in Python. Or use kubectl to deploy a simple Kubernetes application:
kubectl create deployment hello-node --image=gcr.io/hello-minikube-zero-install/hello-node部署应用
代码语言：javascript复制$ oc new-app openshift/hello-openshift
--> Found container image 7af3297 (23 months old) from Docker Hub for "openshift/hello-openshift"
* An image stream tag will be created as "hello-openshift:latest" that will track this image
* This image will be deployed in deployment config "hello-openshift"
* Ports 8080/tcp, 8888/tcp will be load balanced by service "hello-openshift"
* Other containers can access this service through the hostname "hello-openshift"

Application is not exposed. You can expose services to the outside world by executing one or more of the commands below:
'oc expose svc/hello-openshift'
Run 'oc status' to view your app.
