In this talk we discuss how you can deploy both NGINX and NGINX Plus within Kubernetes as an Ingress Controller

1. NGINX as an Ingress Controller in
Kubernetes
Speaker: Kevin Jones
Global Product Specialist

2. But first…

3. 3
“... when I started NGINX,
I focused on a very specific
problem – how to handle more
customers per a single
server.”
- Igor Sysoev, NGINXcreator and founder

9. NGINX for Microservices
9
NGINX helps ensure microservices are:
• Connected
• Served
• Authenticated
• Secured
• Cached
• Load Balanced
• Scaled

10. NGINX for API Gateways
10
NGINX provides:
• Integration
• Security
• Request Routing
• Optimization
• Scalability

11. NGINX for Hybrid Cloud & Scaling
11
NGINX Plus can:
• Run anywhere
• React to environment downtime
• Outperformcloud load balancers
• Load balance across locations
• Scale without additional costs

12. Benefits of Kubernetes

13. 13
Kubernetes is an open-source system for
automating deployment, scaling, and
management of containerized applications

14. Kubernetes makes ops easy…
• Run anywhere
• Rolling updates
• Fault Tolerance
• Horizontal Scaling
• Load Balancing
• YAML… and more!

• Simple and easy to setup
• Limited to layer 4 load balancing
• If you need advanced load balancing
consider using an Ingress controller so you
can bring your own!
Built-in load balancing

19. Why use an Ingress?

20. 20
Ingress
• Kubernetes resource
• Benefits
• Externally reachable URLs
• Advanced L7 Load Balancing
• SSL/TLS
• SNI (hostname based routing)

21. 21
Ingress Example – Basic

22. 22
Ingress Example – URL based routing

23. 23
Ingress Example – Host based routing

24. 24
Ingress Example – SSL offloading

25. 25
Ingress
• Pluggableload balancer implementation:
• NGINX/NGINX Plus
• GCE HTTP load balancer
• HAProxy
• … and others
- A load balancer is integrated via an Ingress controller that
you must deploy

26. Deploying NGINX and NGINX Plus as
an Ingress Controller

27. NGINX and NGINX Plus
27
NGINX
• Load balancing w/ SSL/TLS
termination
• WebSocket and HTTP/2 support
• Layer 7 Routing/ Modification
NGINX Plus
• Session persistence
• JWT authentication
• 24/7 support, no additional cost
• Advanced Monitoring… and more!

28. 28
NGINX Ingress Controller
• Runs in a container
• Well designed, fast and efficient golang script under the hood
• Community driven codebase
• Available for NGINX and NGINX Plus

My demo today…
• URL based routing
• Hostname based routing
• SSL termination at LB
• Support for scaling of replicas at LB via dynamic reconfiguration

My demo today…
• Café themed application
• Two services (URL routing)
◦ /Tea
◦ /Coffee

32. Configuring NGINX or NGINX Plus
without Ingress

33. 33
Data store + template
• Register services with a data
store (aka etcd or consul)
• Template the NGINX
configuration and manage
NGINX service via CLI (confd
or consul template)
datastore

34. 34
We love APIs!
• Services availabilityis
managed by kubernetes and
availablevia API
• Orchestration script can be in
any language
• NGINX Plus upstreams
managed dynamically without
configuration reload

Service Discovery ;D
• Built in DNS resolver
• Control over TTL
• Easily Integrates with existing
DNS based service discovery

38. If you like NGINX,
you’ll love NGINX Plus!
