When you run

kubectl run  --image= --port=

You are implicitly running

kubectl run --generator=deployment/apps.v1 run  --image= --port=

Which tells kubernetes what resource it needs to generate

It is quite overwhelming to deal with such a variety of parameters with run

Hence, as of v1.15 and greater, all --generators apart from run-pod are deprecated.

See the table below

Pod                                 v1                  kubectl run --generator=run-pod/v1
ReplicationController (deprecated)  v1                  kubectl run --generator=run/v1
Deployment (deprecated)         extensions/v1beta1      kubectl run --generator=deployment/v1beta1
Deployment (deprecated)         apps/v1beta1            kubectl run --generator=deployment/apps.v1beta1
Job (deprecated)                batch/v1                kubectl run --generator=job/v1
CronJob (deprecated)            batch/v2alpha1          kubectl run --generator=cronjob/v2alpha1
CronJob (deprecated)            batch/v1beta1           kubectl run --generator=cronjob/v1beta1

Solution is to either use create or apply -f. The latter uses a yml file.
