kubectl run is a command that creates a new deployment in Kubernetes. The deployment is responsible for managing a group of replicas of your application, ensuring that the desired number of replicas are running at all times.
kubectl create deployment is another command that creates a new deployment in Kubernetes. The syntax for this command is slightly different from kubectl run, but the basic idea is the same.
Here is an example of how to use kubectl run to create a new deployment:
kubectl run web-server --image=nginx:latest --replicas=3
This command creates a new deployment called “web-server” that runs 3 replicas of the “nginx” container image.
Here is the equivalent command using kubectl create deployment:
kubectl create deployment web-server --image=nginx:latest
kubectl scale deployment web-server --replicas=3
Both of these commands will create a new deployment in Kubernetes that runs 3 replicas of the “nginx” container image. The main difference is the syntax used to specify the deployment parameters.
