Cover Image for Working with Namespaces and Services in Kubernetes

What are namespaces?

Namespaces are the virtual environment or cluster inside a minikube Cluster.t is a way to partition resources and create logical boundaries within a cluster. By organizing components of an application into different namespaces, you can achieve separation and control over the resources allocated to each component.

It can use for the following purposes:

  1. Resources grouped in namespaces:

    Namespaces groups the Cluster into different sections provide developers to organize their work. for eg: different namespaces run different components of an application.

  2. conflicts with the same application:

    it decreases conflicts as same-name applications by creating different environments for different applications which does not harm the functioning of others.

  3. Resource sharing: (staging and deployments, version of application) A common namespace can be used in other namespaces to avoid repetition and increase accessibility.

  4. Environment separation: Namespaces enable you to create separate environments, such as development, staging, and production, for different stages of the application lifecycle. Each domain can have its own set of namespaces, making it easier to manage and deploy the application across various stages.

how to create a namespace?

command kubectl create namespace <namespace-name> to create a Namespace

Task 2:

Services: Kubernetes Services provide a stable network endpoint to access a group of Pods. They enable load balancing and service discovery for your application. Depending on your networking requirements, there are different types of services, such as ClusterIP, NodePort, and LoadBalancer.

Load Balancing: I can assist you in setting up and configuring load balancing for your applications running on Kubernetes, using features like Kubernetes Services or an Ingress controller.

for eg: if a large no. of requests get into your server, the work of the load balancer is to distribute the request into different poed/ replicas of the server to manage downtime.

Networking:

Networking in Kubernetes plays a crucial role in enabling communication between different components of your application running in the cluster. Kubernetes provides networking capabilities that allow pods, services, and other resources to communicate with each other both within and outside the cluster.
