Create New Namespaces

You can create your namespace by using the command.

$ kubectl create namespace your-namespace

As you can see we have successfully created namespace gfg.

Creating Component in a Namespace:

To create a component in a namespace you can either give the –namespace flag or specify the namespace in the configuration file.

Method 1: Using –namespace flag

$ kubectl apply -f your_config.yaml --namespace=your-namespace

then you can check resources in your namespace using kubectl get and specify namespace using -n

Kubernetes – Namespaces

Pre-requisite:- Kubernetes

Kubernetes Namespace is a mechanism that enables you to organize resources. It is like a virtual cluster inside the cluster. A namespace isolates the resources from the resources of other namespaces. For example, You need to have different names for deployments/services in a namespace but you can have the same name for deployment in two different namespaces.

Initial Namespaces

kube-system: System processes like Master and kubectl processes are deployed in this namespace; thus, it is advised not to create or modify the namespace. kube-public: This namespace contains publicly accessible data like a configMap containing cluster information. kube-node-lease: This namespace is the heartbeat of nodes. Each node has its associated lease object. It determines the availability of a node. default: This is the namespace that you use to create your resources by default....

Working with Namespaces

Namespaces in kubernetes are a way to create and organize virtual clusters within physical clusters where we can isolate a group of resources within a single cluster. Namespace helps to organize resources such as pods, services, and volumes within the cluster. Workloads of applications and authorization can be managed by using kubernetes namespaces....

Benefits of Using Kubernetes Namespaces

Isolation of resources for different teams: Namespace will isolate the resources which are going to be used in the Kubernetes cluster. Namespace in Kubernetes is useful for security, performance, or organizational reasons. A namespace can be created for different teams who are going to work on the Kubernetes cluster such as developers teams, testing teams, and other teams. RBAC: Namespaces can increase the security of resources that are deployed by using role-based access control. For example, if the resources are deployed in the dev namespace by using RABAC we control the permissions to the developer team members in that dev namespace in the Kubernetes. Organization of resources: In a Kubernetes cluster it is very important to maintain the resources which are deployed in the cluster in an organized manner it can be done by using Kubernetes namespaces where you can track and manage the resource which is deployed. Increase Performance: Resources that are deployed in the Kubernetes cluster are isolated from each other which will help to reduce the burden on the resources like CPU and memory....
