What is the rollback strategy for NGINX Ingress?

In the world of Kubernetes and microservices, NGINX Ingress serves as a powerful tool for managing incoming traffic. However, deployments are not always perfect, and the need for a rollback strategy is crucial. A rollback strategy for NGINX Ingress typically involves restoring to a previous, stable configuration when an update fails or causes issues. Below is a simple approach to implementing a rollback strategy:

# Step 1: Apply the new configuration
kubectl apply -f ingress-config.yaml

# Step 2: Monitor the deployment
kubectl get pods -n 

# If an issue is detected, roll back to the previous configuration
kubectl rollout undo deployment  -n 
    

By using the `kubectl rollout undo` command, you can revert the changes made to the NGINX Ingress deployment, thereby restoring service stability.
