# login as [developer] account [cent@dlp ~]$ eval $(crc oc-env) [cent@dlp ~]$ oc login -u developer https://api.crc.testing:6443
# create [test-project] project [cent@dlp ~]$ oc new-project test-project Now using project "test-project" 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/serve_hostname # deploy [rails-postgresql-example] application [cent@dlp ~]$ oc new-app rails-postgresql-example warning: Cannot find git.
