Updating An Ingress

Updating the Ingress involves in modifying the configuration file of the Routing Table. Routing rules of how external traffic is routed to services within the kubernetes cluster as to be modified. The following are steps for updating an Ingress to define rules for HTTP and HTTPS traffic to different services based on criteria like hostname and paths.

Step 1: Modify the YAML Configuration

  • Here, we can modify the yaml configuration file that defines the ingress resources using `kubectl edit` or by directly modifying the YAML file.

Step 2: Apply Changes

  • After once the changes are made in the configuration file, you can apply the changes using the following command in the kubernetes cluster
kubectl apply -f ingress.yml

Step 3: Verfiication

  • Once we applied the changes, we should verify whether the ingress is updated correctly or not using the following command:
kubectl get ingress

( or )

  • We can also verify it by checking the status in our kubernetes dashboard.

Step 4: Testing

  • It is important to test the updated configuration of ingress to ensure the traffic is routed as per expected or not. we can perform this by sending the requests to the associated services and verifying its responses.

Step 5: Rollback ( if necessary )

  • If the update leads to any issues or anying unexpected behaviour, we can rollback it to the previous configuration by reapplying the older YAML file.

What Is Kubernetes Ingress ?

Ingress is a Kubernetes API object that is used to expose HTTP and HTTPS routes from outside the cluster to services inside the cluster. It provides a single entry point into a cluster hence making it simpler to manage applications and troubleshoot routing issues. In this article, we will discuss what Kubernetes Ingress is. what is an Ingress controller and How does it resolve the routing problem issue? we will guide you on step-by-step implementation of Kubernetes Ingress.

Differences Between Ingress, NodePort And LoadBalancer

Ingress NodePort LoadBalancer Definition Ingress is a Kubernetes API object that is used to expose HTTP and HTTPS routes from outside the cluster to services inside the cluster. NodePort is a Service that is accessible on a static Port on each Worker Node in the cluster. Load Balancer Service type allows the Service to become accessible externally through a Cloud Provider’s Load Balancer functionality. Use Ingress provides a single entry point into a cluster hence making it simpler to manage applications and troubleshoot routing issues. NodePort Service makes the external traffic accessible on static or fixed port on each worker Node LoadBalancer Service is an extension of NodePort Service. To understand LoadBalancer Service type, you must know about Load Balancing. Load Balancing is the process of dividing a set of tasks over a set of resources in order to make the process fast and efficient. Configuration Ingress is configured with the help of rules that define how to route traffic to different services based on hostnames or paths. NodePort is configured by specifying the NodePort and the target port for the service. LoadBalancer is als configured same as NodePort. Range No specific port range is defined for Ingress. NodePort range is between 30000-32767 LoadBalancer uses standard HTTP and HTTPS ports...
