	Log in as administrator:

	Username: kubeadmin

	Password: 6EWtq-5qXX3-Sm3i8-Kr6Gq

	Log in as user:

	Username: developer

	Password: developer

	Use the 'oc' command line interface:

	$ eval $(crc oc-env)

	$ oc login -u developer https://api.crc.testing:6443

	=========================================================
	Step 12 - Setup a Path
	=========================================================
	$ crc oc-env

	export PATH="/home/prayag/.crc/bin/oc:$PATH"

	# Run this command to configure your shell:
	# eval $(crc oc-env)

	[prayag@localhost ~]$ 'export PATH="/home/prayag/.crc/bin/oc:$PATH"

	[prayag@localhost ~]$ echo 'export PATH="/home/prayag/.crc/bin/oc:$PATH"' >> .bashrc

	[prayag@localhost ~]$ which oc
	~/.crc/bin/oc/oc

	=========================================================
	Step 13 - Login as kubeadmin
	=========================================================
	$ oc login -u kubeadmin -p 6EWtq-5qXX3-Sm3i8-Kr6Gq https://api.crc.testing:644
	$ oc get all

	service/openshift ExternalName <none> kubernetes.default.svc.cluster.local <none> 15d

	$ oc get nodes
	NAME STATUS ROLES AGE VERSION

	oc new-project <projectname>

	========================================
	Step 15 - Create new project and new app
	========================================
	$ oc new-project web-app
	Now using project "web-app" on server "https://api.crc.testing:6443".
	You can add applications to this project with the 'new-app' command. For example, try:

	oc new-app rails-postgresql-example

	to build a new example application in Ruby. Or use kubectl to deploy a simple Kubernetes application:

	kubectl create deployment hello-node --image=k8s.gcr.io/e2e-test-images/agnhost:2.33 -- /agnhost serve-hostname

	$ oc new-app --template=openshift/nginx-example --name=nginx-app --param=NAME=nginx-app

	$ oc status
	In project web-app on server https://api.crc.testing:6443

	$ oc get svc
	$ oc get route nginx-app
	$ curl nginx-app-web-app.apps-crc.testing

	$ oc new-app --name=httpd-01 httpd
