In this space, Kubernetes resources come and go, and the restrictions on who can or cannot modify resources are relaxed to enable agile development.\n\nThe operations team would like to maintain a space in the cluster where they can enforce strict procedures on who can or cannot manipulate the set of Pods, Services, and Deployments that run the production site.\n\nOne pattern this organization could follow is to partition the Kubernetes cluster into two namespaces: development and production.\n\nLet's create two new namespaces to hold our work.\n\nUse the file namespace-dev.yaml which describes a development namespace\n\nCreate the development namespace using kubectl.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl create -f https://k8s.io/examples/admin/namespace-dev.yaml\n```\n\nSave the following contents into file namespace-prod.yaml which describes a production namespace\n\nAnd then let's create the production namespace using kubectl.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl create -f https://k8s.io/examples/admin/namespace-prod.yaml\n```\n\nTo be sure things are right, let's list all of the namespaces in our cluster.\n\nBounded code example (external data; do not execute automatically):\n```shell\nkubectl get namespaces --show-labels\n```\n\nBounded code example (external data; do not execute automatically):\n```text\nNAME          STATUS    AGE       LABELS\ndefault       Active    32m       <none>\ndevelopment   Active    29s       name=development\nproduction    Active    23s       name=production\n```\n\nAttribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
