Ingress is a Kubernetes resource that controls how external traffic reaches services running within a Kubernetes cluster. It acts as a reverse proxy and load balancer, enabling HTTP and HTTPS routing to backend services based on hostnames or URL paths.
Typically used in cloud-native and containerized environments, Ingress provides a centralized way to manage external access without exposing each service directly via a public IP. It works in conjunction with an Ingress controller, which implements the routing rules defined in Ingress resources. Common Ingress controllers include NGINX, Traefik, and AWS ALB Ingress Controller.
Professionals working with Ingress are expected to understand Kubernetes networking models, TLS termination, and routing configuration. They must be able to define Ingress rules using YAML manifests, configure SSL certificates, and troubleshoot routing issues. This skill is essential for roles such as DevOps engineers, platform engineers, and cloud architects managing scalable, secure microservices deployments.
- Configures HTTP/HTTPS routing to Kubernetes services
- Integrates with load balancers and TLS providers
- Enforces routing rules based on host or path
- Supports path rewriting and load balancing
- Works with Ingress controllers like NGINX or Traefik
- Manages SSL/TLS termination for secure traffic
Knowledge of related Kubernetes objects—such as Services, Secrets, and NetworkPolicies—is often required to use Ingress effectively. Employers in technology, finance, and SaaS industries frequently seek this skill for infrastructure and platform teams managing production-grade Kubernetes clusters.
