3. View the details of the deployment, then the pod. Work through the output slowly. Knowing what a healthy deployment

and looks like can be helpful when troubleshooting issues. Again the Tab key can be helpful when using long auto-

generated object names. You should be able to type ﬁrstpodTab and the name will complete when viewing the pod.

student@ckad-1:~$ kubectl describe deployment firstpod

Name: firstpod

Namespace: default

CreationTimestamp: Fri, 25 Jul 2018 16:46:57 +0000

Labels: app=firstpod

Annotations: deployment.kubernetes.io/revision=1

Selector: app=firstpod

Replicas: 1 desired | 1 updated | 1 total | 1 available....

StrategyType: RollingUpdate

student@ckad-1:~$ kubectl describe pod firstpod-6bb4574d94-rqk76

Name: firstpod-6bb4574d94-rqk76

Namespace: default

Priority: 0

PriorityClassName: <none>

Node: ckad-1/10.128.0.2

4. Note that the resources are in the default namespace. Get a list of available namespaces.

student@ckad-1:~$ kubectl get namespaces

NAME STATUS AGE

default Active 20m

kube-node-lease Active 20m

kube-public Active 20m

kube-system Active 20m

5. There are two other namespaces. Look at the pods in the kube-system namespace.

student@ckad-1:~$ kubectl get pod -n kube-system

NAME READY STATUS RESTARTS AGE

calico-node-5ftrr 2/2 Running 0 24m

calico-node-f7zrw 2/2 Running 0 21m

coredns-fb8b8dccf-cmkds 1/1 Running 0 24m

coredns-fb8b8dccf-grltk 1/1 Running 0 24m

etcd-v141-r24p 1/1 Running 0 23m

<output_omitted>

6. Now look at the pods in a namespace that does not exist. Note you do not receive an error.

student@ckad-1:~$ kubectl get pod -n fakenamespace

No resources found.

7. You can also view resources in all namespaces at once. Use the --all-namespaces options to select objects in all

namespaces at once.

student@ckad-1:~$ kubectl get pod --all-namespaces

NAMESPACE NAME READY STATUS RESTARTS AGE

default firstpod-69cfdfd8d9-kj6ql 1/1 Running 0 44m

kube-system calico-node-5ftrr 2/2 Running 0 92m

kube-system calico-node-f7zrw 2/2 Running 0 89m

kube-system coredns-fb8b8dccf-cmkds 1/1 Running 0 92m

<output_omitted>

8. View several resources at once. Note that most resources have a short name such as rs for ReplicaSet, po for Pod,

svc for Service, and ep for endpoint. Note the endpoint still exists after we deleted the pod.

student@ckad-1:~$ kubectl get deploy,rs,po,svc,ep

NAME READY UP-TO-DATE AVAILABLE AGE

deployment.extensions/firstpod 1/1 1 1 4m

NAME DESIRED CURRENT READY....

replicaset.extensions/firstpod-6bb4574d94-rqk76 1 1 1 ....

NAME READY STATUS RESTARTS AGE

pod/firstpod-6bb4574d94-rqk76 1/1 Running 0 4m

NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE

service/basicservice NodePort 10.108.147.76 <none> 80:31601/TCP 21m

service/kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 21m

NAME ENDPOINTS AGE

endpoints/basicservice <none> 21m

endpoints/kubernetes 10.128.0.3:6443 21m

9. Delete the ReplicaSet and view the resources again. Note that the age on the ReplicaSet and the pod it controls is

now less than a minute. The deployment controller started a new ReplicaSet when we deleted the existing one, which

started another pod when the desired conﬁguration did not match the current status.

student@ckad-1:~$ kubectl delete rs firstpod-6bb4574d94-rqk76

replicaset.extensions "firstpod-6bb4574d94-rqk76" deleted

student@ckad-1:~$ kubectl get deployment,rs,po,svc,ep

NAME READY UP-TO-DATE AVAILABLE AGE

deployment.extensions/firstpod 1/1 1 1 7m

NAME DESIRED CURRENT....

replicaset.extensions/firstpod-6bb4574d94-rqk76 1 1 ....

NAME READY STATUS RESTARTS AGE

pod/firstpod-7d99ffc75-p9hbw 1/1 Running 0 12s

NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE

service/kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 24m

NAME ENDPOINTS AGE

endpoints/kubernetes 10.128.0.2:6443 80m

endpoints/basicservice <none> 21m

10. This time delete the top-level controller. After about 30 seconds for everything to shut down you should only see the

cluster service and endpoint remain for the cluster and the service we created.

student@ckad-1:~$ kubectl delete deployment firstpod

deployment.extensions "firstpod" deleted
