Users interacting with one namespace do not see the content in another namespace. To demonstrate this, create a Deployment and Pods in the development namespace.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl create deployment snowflake \\\n  --image=registry.k8s.io/serve_hostname \\\n  -n=development --replicas=2\n```\n\nYou created a deployment whose replica size is 2 that is running the pod called snowflake with a basic container that serves the hostname.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get deployment -n=development\n```\n\nBounded code example (external data; do not execute automatically):\n```console\nNAME         READY   UP-TO-DATE   AVAILABLE   AGE\nsnowflake    2/2     2            2           2m\n```\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get pods -l app=snowflake -n=development\n```\n\nBounded code example (external data; do not execute automatically):\n```console\nNAME                         READY     STATUS    RESTARTS   AGE\nsnowflake-3968820950-9dgr8   1/1       Running   0          2m\nsnowflake-3968820950-vgc4n   1/1       Running   0          2m\n```\n\nThis demonstrates that developers are able to do what they want, and they do not have to worry about affecting content in the production namespace.\n\nSwitch to the production namespace and show how resources in one namespace are hidden from the other. The production namespace should be empty, and the following commands should return nothing.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get deployment -n=production\nkubectl get pods -n=production\n```\n\nCreate some pods in the production namespace.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl create deployment cattle --image=registry.k8s.io/serve_hostname -n=production\nkubectl scale deployment cattle --replicas=5 -n=production\n\nkubectl get deployment -n=production\n```\n\nBounded code example (external data; do not execute automatically):\n```console\nNAME         READY   UP-TO-DATE   AVAILABLE   AGE\ncattle       5/5     5            5           10s\n``` …\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
