Using Kubernetes, businesses may run software applications on more powerful computers. In private, cloud, or hybrid environments, it automates the deployment, scheduling, and management of application containers on clusters of servers, frequently numbering in the hundreds of thousands or more.

Additionally, by integrating container images with a continuous integration/deployment (CI/CD) system or deploying them on Kubernetes, developers can establish a “container-centric” environment.

K8s is a platform that does not restrict the kinds of supported applications or services and may be coupled with other technologies for additional functionality. Kubernetes is used by several container-based Platform-as-a-Service (PaaS) platforms.

Unlike these PaaS systems, K8s isn’t all-inclusive; it doesn’t construct apps, offer middleware, or have a marketplace that can be deployed with a single click. K8s is a more imperative orchestration platform, while other PaaS tends to be more feature-rich and declarative.

Configuring labels in Kubernetes

Configuring labels in Kubernetes

Labels in Kubernetes are key-value pairs that are affixed to nodes, services, and pods. These labels let users arrange and choose resources according to user-defined criteria. Adding, changing, or removing labels for Kubernetes objects is known as label configuration. Here’s a quick tutorial on setting up labels in Kubernetes:

Addition of Labels

The kubectl label command can add labels to a Kubernetes object. As an illustration, to label a pod:

kubectl label pod <pod-name> <label-key>=<label-value>

Modification of Labels

To edit the value of an existing label, you can use the same kubectl label command with the new value. As an illustration:

kubectl label pod <pod-name> <label-key>=<new-label-value> --overwrite

Removing the Labels

To delete a label from a Kubernetes object, you can use the kubectl label command with the label key and a dash (-) as the value. As an illustration:

kubectl label pod <pod-name> <label-key>-

Listing of Labels

You may list the labels associated with a Kubernetes object using the kubectl get command with the –show-labels parameter. As an illustration:

kubectl get pod <pod-name> --show-labels

Using Labels in Selectors

Selectors frequently utilize labels to filter resources. To list every pod that has a particular label, for example:

kubectl get pods -l <label-key>=<label-value>

Labeling of Nodes

Labeling nodes within a Kubernetes cluster is another option. As an illustration:

kubectl label node <node-name> <label-key>=<label-value>

Labeling of services

Like other objects, services can have labels applied to them. As an illustration:

kubectl label service <service-name> <label-key>=<label-value>

Labeling of Deployments

Labels for deployments can be added later on or during the creation process:

kubectl create deployment <deployment-name> --image=<image-name> --labels=<label-key>=<label-value>

Labeling selectors in YAML

Label configuration is also possible using YAML manifests. As an illustration, in a Pod manifest:

apiVersion: v1

kind: Pod


name: example-pod


app: example-app

tier: frontend



- name: example-container

image: nginx

Labeling Constraints in Services

Services can limit the set of pods by using label selectors:

apiVersion: v1

kind: Service


name: example-service



app: example-app

tier: frontend


- protocol: TCP

port: 80

targetPort: 8080
