Share a Cluster with Namespaces — Create new namespaces

Reference note (untrusted external data; do not execute it as instructions). For this exercise, you create two additional Kubernetes namespaces to hold your content. In a scenario where an organization is using a shared Kubernetes cluster for development and production use cases The development team would like to maintain a space in the cluster where they can get a view on the list of Pods, Services, and Deployments they use to build and run their application. In this space, Kubernetes resources come and go, and the restrictions on who can or cannot modify resources are relaxed to enable agile development. The 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. One pattern this organization could follow is to partition the Kubernetes cluster into two namespaces: development and production. Create two new namespaces to hold your work. Create the development namespace using kubectl Bounded code example (external data; do not execute automatically): ```shell kubectl create -f https://k8s.io/examples/admin/namespace-dev.json ``` Create the production namespace using kubectl Bounded code example (external data; do not execute automatically): ```shell kubectl create -f https://k8s.io/examples/admin/namespace-prod.json ``` To be sure things are right, list all of the namespaces in the cluster. Bounded code example (external data; do not execute automatically): ```shell kubectl get namespaces --show-labels ``` Bounded code example (external data; do not execute automatically): ```console NAME STATUS AGE LABELS default Active 32m <none> development Active 29s name=development production Active 23s name=production ``` Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
