kubectl run command does not seems to generate deployment
In the "Managing State with Deployments" it says :
"The default controller for a container deployed via kubectl run command is a Deployment."
But the kubectl run command generate/deploy Pod object not Deployment :
$ kubectl run nginx --image=nginx --dry-run=client -o yaml apiVersion: v1 kind: Pod metadata: creationTimestamp: null labels: run: nginx name: nginx spec: containers: - image: nginx name: nginx resources: {} dnsPolicy: ClusterFirst restartPolicy: Always status: {}

Hi @Vampouille,
The
kubectl run
command used to allow the creation of objects like the pod, deployment, job, etc. all with the help of a--generator
flag.Regards,

@chrispokorni Since 1.18, kubectl run command generates only Pod. The offical documentation says : "Create and run a particular image in a pod."
https://kubernetes.io/docs/reference/generated/kubectl/kubectl-commands#run
If you want to create Deployment, DaemonSet or Job you need to use kubectl create command.

Moreover Kates 1.25 doesn't have
--generator
flag at all.0 -
Hi @Vampouille,
You are correct, Deployment and Job objects can be created with the
kubectl create
command, but not the DaemonSet object.Also, as @oleksazhel noted, the
--generator
flag, which used to allow the creation of Deployment, Job, and other operators, is no longer supported.Regards,
