How to create a deployment with --record?
In the answer video, he is creating a run command to create a deployment but when I used the same command k run nginx-deploy --image=nginx:1.16 --replicas=1 --record , it only creates a pod.
Marco Tony:
k create deploy...
George Lazaroff:
kubectl create deploy nginx-deploy --image=nginx:1.16 --replicas=1
kubectl set image deploy nginx-deploy nginx=nginx:1.17 --record
kubectl rollout history deploy nginx-deploy
Ankit Arora:
They should fix the answer videos as well.
George Lazaroff:
image is fixed 1.17 :)sry
Ankit Arora:
@George Lazaroff Can you please help me with question number 7 as well?
I am using the following command to check nslookup but getting timed out.
k run --generator=run-pod/v1 busybox1 --image busybox:1.28 --rm -it -- nslookup nginx-resolver-service
George Lazaroff:
whats the question ?
George Lazaroff:
i dont remember it, i passed but …
George Lazaroff:
kubectl run busybox1 --image=busybox:1.28 --rm -it -- nslookup nginx-resolver-service.<namespace>.svc > <file name>
Ankit Arora:
Ques:
Create an nginx pod called nginx-resolver using image nginx, expose it internally with a service called nginx-resolver-service. Test that you are able to look up the service and pod names from within the cluster. Use the image: busybox:1.28 for dns lookup. Record results in /root/CKA/nginx.svc and /root/CKA/nginx.pod
George Lazaroff:
into which namespace are located the service and pod
George Lazaroff:
kubectl get pod, svc --all-namespace
kubectl run busybox1 --image=busybox:1.28 --rm -it -- nslookup nginx-resolver-service.default.svc > /root/CKA/nginx.svc
kubectl get pod -o wide | grep nginx-resolver
check and take the IP - 10.10.1.2 its only example
kubectl run busybox1 --image=busybox:1.28 --rm -it -- nslookup 10-10-1-2.default.pod > /root/CKA/nginx.pod
George Lazaroff:
verify the commands before to redirect them to the file
or check the files
cat /root/CKA/nginx.pod
cat /root/CKA/nginx.svc
