Rio is a user-oriented end-to-end container solution with a focus on keeping containers simple and combating the current trend of complexity.
It's kept fun and simple though it's familiar and opinionated user experience.
Additionally, Rio is a "Cloud Native Container Distribution" meaning it includes built-in Cloud Native technologies such as Kubernetes, Istio, Containerd, etc.
so that the user need not be an expert in installing, using, and maintaining these systems.

yassan@rio01:~$ rio run -p 80/http --name test/svc --scale=3 ibuildthecloud/demo:v1

状態の確認
yassan@rio01:~$ rio ps

test/svc ibuildthecloud/demo:v1 8 seconds ago (3/0/0)/3 pending http://svc.test.g50yg5.lb.rancher.cloud
と直後ではなっていますが、しばらくすると以下のようになります。
yassan@rio01:~$ rio ps

yassan@rio01:~$ curl http://svc.test.g50yg5.lb.rancher.cloud
Hello World
次にv3でデプロイしてみます。
yassan@rio01:~$ rio stage --image=ibuildthecloud/demo:v3 test/svc:v3
test-124a4837:svc
# Serviceの状態を確認（v1とv3の両方が存在しています）
yassan@rio01:~$ rio ps

まぁおおよそ、半々出てますね！
では、v3を完全に反映させます。
yassan@rio01:~$ rio promote test/svc:v3
test-124a4837:svc
# Serviceの状態の確認（v3のENDPOINTがv1のときのものに変わってますね）
yassan@rio01:~$ rio ps
