Error from server (AlreadyExists): deployments.extensions "nginx-test" already exists

This error message indicates that a Kubernetes deployment named “nginx-test” already exists in the cluster. You cannot create a new deployment with the same name as an existing one.

To resolve this issue, you can either delete the existing deployment and then recreate it with the desired configuration, or you can update the existing deployment to make any necessary changes.

To delete the existing deployment, use the command:

kubectl delete deployment nginx-test

Once the deployment is deleted, you can create a new one with the desired configuration using the appropriate kubectl command.

Alternatively, if you want to update an existing deployment instead of deleting it and creating a new one, you can use the kubectl apply command to apply changes to an existing resource. For example:

kubectl apply -f nginx-deployment.yaml

This will update the existing “nginx-test” deployment based on the contents of your updated YAML file (assuming it contains valid Kubernetes Deployment definition).
