Tectonic ships with CoreOS's signature automated operations, runs multi-cloud, and is the fastest, most secure path to Kubernetes.
In this tutorial you will learn how to delete a deployment using kubectl and the Tectonic Console.
First, use kubectl get all to list all applications and services on your cluster.
$ kubectl get all
NAME READY STATUS RESTARTS AGE
po/nginx-deployment-1447934386-45snm 1/1 Running 1 3d
po/nginx-deployment-1447934386-4q0ms 1/1 Running 1 3d
po/nginx-deployment-1447934386-mjdd5 1/1 Running 1 3d

NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
svc/kubernetes 10.3.0.1 <none> 443/TCP 4d
svc/simple-service 10.3.0.178 a1c717248163e... 80:30984/TCP 3d
svc/simple-service-two 10.3.0.56 a16b97a7b1644... 80:32185/TCP 3d
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
deploy/cookies 5 5 5 5 3d
deploy/nginx-deployment 3 3 3 3 3d
deploy/simple-deployment 3 3 3 3 3d
deploy/simple-deployment-two 3 0 0 0 3d
NAME DESIRED CURRENT READY AGE
rs/nginx-deployment-1447934386 3 3 3 3d
rs/simple-deployment-169731590 0 0 0 19h
rs/simple-deployment-256231244 0 0 0 3d
rs/simple-deployment-305980935 3 3 3 19h
Next, delete the simple app's Deployment and Service using kubectl delete:
$ kubectl delete deployment/simple-deployment svc/simple-service
deployment "simple-deployment" deleted
service "simple-service" deleted
This will delete the Deployment (including Pods and Replica Sets) and the Service associated with the simple app created earlier.
$ kubectl get all
