external load balancer for kubernetes nginx

Content Library. The NGINX Load Balancer Operator is a reference architecture for automating reconfiguration of the external NGINX Plus load balancer for your Red Hat OCP or a Kubernetes cluster, based on changes to the status of the containerized applications. Now that we have NGINX Plus up and running, we can start leveraging its advanced features such as session persistence, SSL/TLS termination, request routing, advanced monitoring, and more. If you’re running in a public cloud, the external load balancer can be NGINX Plus, F5 BIG-IP LTM Virtual Edition, or a cloud‑native solution. As a reference architecture to help you get started, I’ve created the nginx-lb-operator project in GitHub – the NGINX Load Balancer Operator (NGINX-LB-Operator) is an Ansible‑based Operator for NGINX Controller created using the Red Hat Operator Framework and SDK. In commands, values that might be different for your Kubernetes setup appear in italics. However, NGINX Plus can also be used as the external load balancer, improving performance and simplifying your technology investment. Here is the declaration file (webapp-rc.yaml): Our controller consists of two web servers. However, the external IP is always shown as "pending". Building Microservices: Using an API Gateway, Adopting Microservices at Netflix: Lessons for Architectural Design, A Guide to Caching with NGINX and NGINX Plus. Step 2 — Setting Up the Kubernetes Nginx Ingress Controller. Load-Balancing in/with Kubernetes a Service can be used to load-balance traffic to pods at layer 4 Ingress resource are used to load-balance traffic between pods at layer 7 (introduced in kubernetes v1.1) we may set up an external load-balancer to load … An external load balancer provider in the hosting environment handles the IP allocation and any other configurations necessary to route external traffic to the Service. It is built around an eventually consistent, declarative API and provides an app‑centric view of your apps and their components. As specified in the declaration file for the NGINX Plus replication controller (nginxplus-rc.yaml), we’re sharing the /etc/nginx/conf.d folder on the NGINX Plus node with the container. Together with F5, our combined solution bridges the gap between NetOps and DevOps, with multi-cloud application services that span from code to customer. There are two main Ingress controller options for NGINX, and it can be a little confusing to tell them apart because the names in GitHub are so similar. As I mentioned in my Kubernetes homelab setup post, I initially setup Kemp Free load balancer as an easy quick solution.While Kemp did me good, I’ve had experience playing with HAProxy and figured it could be a good alternative to the extensive options Kemp offers.It could also be a good start if I wanted to have HAProxy as an ingress in my cluster at some point. NGINX-LB-Operator drives the declarative API of NGINX Controller to update the configuration of the external NGINX Plus load balancer when new services are added, Pods change, or deployments scale within the Kubernetes cluster. Google Kubernetes Engine (GKE) offers integrated support for two types of Cloud Load Balancing for a publicly accessible application: Create a simple web application as our service. Kubernetes Ingress with Nginx Example What is an Ingress? Then we create the backend.conf file there and include these directives: resolver – Defines the DNS server that NGINX Plus uses to periodically re‑resolve the domain name we use to identify our upstream servers (in the server directive inside the upstream block, discussed in the next bullet). server (twice) – Define two virtual servers: The first server listens on port 80 and load balances incoming requests for /webapp (our service) among the pods running service instances. Traffic from the external load balancer can be directed at cluster pods. As we said above, we already built an NGINX Plus Docker image. For this check to pass on DigitalOcean Kubernetes, you need to enable Pod-Pod communication through the Nginx Ingress load balancer. Kubernetes offers several options for exposing services. This document covers the integration with Public Load balancer. With NGINX Open Source, you manually modify the NGINX configuration file and do a configuration reload. Ingress exposes HTTP and HTTPS routes from outside the cluster to services within the cluster. Before deploying ingress-nginx, we will create a GCP external IP address. Our service consists of two web servers that each serve a web page with information about the container they are running in. People who use Kubernetes often need to make the services they create in Kubernetes accessible from outside their Kubernetes cluster. The operator configures an external NGINX instance (via controller) to Load Balance onto a Kubernetes Service. To designate the node where the NGINX Plus pod runs, we add a label to that node. External Load Balancing, which distributes the external traffic towards a service among available pods as external Load Balancer can’t have direct to pods/containers. upstream – Creates an upstream group called backend to contain the servers that provide the Kubernetes service we are exposing. Kubernetes as a project currently maintains GLBC (GCE L7 Load Balancer) and ingress-nginx controllers. Our Kubernetes‑specific NGINX Plus configuration file resides in a folder shared between the NGINX Plus pod and the node, which makes it simpler to maintain. Kubernetes comes with a rich set of features including, Self-healing, Auto-scalability, Load balancing, Batch execution, Horizontal scaling, Service discovery, Storage orchestration and many more. Announcing NGINX Ingress Controller for Kubernetes Release 1.6.0 December 19, 2019 ... the nodes of the Kubernetes cluster. Its modules provide centralized configuration management for application delivery (load balancing) and API management. Now it’s time to create a Kubernetes service. It’s Saturday night and you should be at the disco, but yesterday you had to scale the Ingress layer again and now you have a pain in your lower back. The cluster runs on two root-servers using weave. One of the main benefits of using nginx as load balancer over the HAProxy is that it can also load balance UDP based traffic. Although the solutions mentioned above are simple to set up, and work out of the box, they do not provide any advanced features, especially features related to Layer 7 load balancing. We run the following command, which creates the service: Now if we refresh the dashboard page and click the Upstreams tab in the top right corner, we see the two servers we added. You configure access by creating a collection of rules that define which inbound connections reach which services. NGINX Controller can manage the configuration of NGINX Plus instances across a multitude of environments: physical, virtual, and cloud. Configure an NGINX Plus pod to expose and load balance the service that we’re creating in Step 2. Note: The Ingress Controller can be more efficient and cost-effective than a load balancer. For more information about service discovery with DNS, see Using DNS for Service Discovery with NGINX and NGINX Plus on our blog. A DNS query to the Kubernetes DNS returns multiple A records (the IP addresses of our pods). For product details, see NGINX Ingress Controller. [Editor – This section has been updated to refer to the NGINX Plus API, which replaces and deprecates the separate dynamic configuration module originally discussed here.]. But what if your Ingress layer is scalable, you use dynamically assigned Kubernetes NodePorts, or your OpenShift Routes might change? In addition to specifying the port and target port numbers, we specify the name (http) and the protocol (TCP). Release 1.6.0 and later of our Ingress controllers include a better solution: custom NGINX Ingress resources called VirtualServer and VirtualServerRoute that extend the Kubernetes API and provide additional features in a Kubernetes‑native way. In this article we will demonstrate how NGINX can be configured as Load balancer for the applications deployed in Kubernetes cluster. In this section we will describe how to use Nginx as an Ingress Controller for our cluster combined with MetalLB which will act as a network load-balancer for all incoming communications. Background. In cases like these, you probably want to merge the external load balancer configuration with Kubernetes state, and drive the NGINX Controller API through a Kubernetes Operator. It is important to note that the datapath for this functionality is provided by a load balancer external to the Kubernetes cluster. Routing external traffic into a Kubernetes or OpenShift environment has always been a little challenging, in two ways: In this blog, I focus on how to solve the second problem using NGINX Plus in a way that is simple, efficient, and enables your App Dev teams to manage both the Ingress configuration inside Kubernetes and the external load balancer configuration outside. In this set up, your load balancer provides a stable endpoint (IP address) for external traffic to access. At F5, we already publish Ansible collections for many of our products, including the certified collection for NGINX Controller, so building an Operator to manage external NGINX Plus instances and interface with NGINX Controller is quite straightforward. The times when you need to scale the Ingress layer always cause your lumbago to play up. Accept cookies for analytics, social media, and advertising, or learn more and adjust your preferences. When incoming traffic hits a node on the port, it gets load balanced among the pods of the service. Traffic routing is controlled by rules defined on the Ingress resource. We identify this DNS server by its domain name, kube-dns.kube-system.svc.cluster.local. As we’ve used a load balanced service in k8s in Docker Desktop they’ll be available as localhost:PORT: – curl localhost:8000 curl localhost:9000 Great! An External Load balancer is possible either in cloud if you have your environment in cloud or in such environment which supports external load balancer. NGINX Ingress resources expose more NGINX functionality and enable you to use advanced load balancing features with Ingress, implement blue‑green and canary releases and circuit breaker patterns, and more. The load balancing that is done by the Kubernetes network proxy (kube-proxy) running on every node is limited to TCP/UDP load balancing. And next time you scale the NGINX Plus Ingress layer, NGINX-LB-Operator automatically updates the NGINX Controller and external NGINX Plus load balancer for you. They’re on by default for everybody else. This load balancer will then route traffic to a Kubernetes service (or ingress) on your cluster that will perform service-specific routing. I will create a simple ha-proxy based container which will observe kubernetes services and respective endpoints and reload its backend/frontend configuration (complemented with SYN eating rule during reload) The configuration is delivered to the requested NGINX Plus instances and NGINX Controller begins collecting metrics for the new application. I’ll be Susan and you can be Dave. Before deploying ingress-nginx, we will create a GCP external IP address. I used the Operator SDK to create the NGINX Load Balancer Operator, NGINX-LB-Operator, which can be deployed with a Namespace or Cluster Scope and watches for a handful of custom resources. The output from the above command shows the services that are running: To create the replication controller we run the following command: To check that our pods were created we can run the following command.

Using NGINX Plus for exposing Kubernetes services to the Internet provides many features that the current built‑in Kubernetes load‑balancing solutions lack. Using Kubernetes external load balancer feature¶ In a Kubernetes cluster, all masters and minions are connected to a private Neutron subnet, which in turn is connected by a router to the public network. When it comes to managing your external load balancers, you can manage external NGINX Plus instances using the NGINX Controller directly. As Dave, you run a line of business at your favorite imaginary conglomerate. The load balancer then forwards these connections to individual cluster nodes without reading the request itself. We call these “NGINX (or our) Ingress controllers”. Because both Kubernetes DNS and NGINX Plus (R10 and later) support DNS Service (SRV) records, NGINX Plus can get the port numbers of upstream servers via DNS. When a user of my app adds a custom domain, a new ingress resource is created triggering a config reload, which causes disru… Delete the load balancer. Each Nginx ingress controller needs to be installed with a service of type NodePort that uses different ports. If the service is configured with the NodePort ServiceType, then the external Load Balancer will use the Kubernetes/OCP node IPs with the assigned port. For simplicity, we do not use a private Docker repository, and we just manually load the image onto the node. This is why you were over the moon when NGINX announced that the NGINX Plus Ingress Controller was going to start supporting its own CRDs. Your option for on-premise is to write your own controller that will work with a load balancer of your choice. I am trying to set up a metalLB external load balancer with the intention to access an nginx pod from outside the cluster using a publicly browseable IP address. The NGINX Load Balancer Operator is a reference architecture for automating reconfiguration of the external NGINX Plus load balancer for your Red Hat OCP or a Kubernetes cluster, based on changes to the status of the containerized applications. Follow the instructions here to deactivate analytics cookies. In this configuration, the load balancer is positioned in front of your nodes. Ask Question Asked 2 years, 1 month ago. NGINX Ingress Controller for Kubernetes. “Who are you? The include directive in the default file reads in other configuration files from the /etc/nginx/conf.d folder. As of this writing, both the Ingress API and the controller for the Google Compute Engine HTTP Load Balancer are in beta. Community Overview Getting Started Guide Learning Paths Introductory Training Tutorials Online Meetups Hands-on Workshops Kubernetes Master Classes Get Certified! NGINX-LB-Operator combines the two and enables you to manage the full stack end-to-end without needing to worry about any underlying infrastructure. Azure Load Balancer is available in two SKUs - Basic and Standard. The Kubernetes service controller listens for Service creation and modification events. Specifying the service type as LoadBalancer allocates a cloud load balancer that distributes incoming traffic among the pods of the service. The load balancer can be any host capable of running NGINX. Kubernetes is an orchestration platform built around a loosely coupled central API. An Ingress is a collection of rules that allow inbound connections to reach the cluster services that acts much like a router for incoming traffic. Blog› [Editor – This section has been updated to use the NGINX Plus API, which replaces and deprecates the separate status module originally used.]. Specifying the service type as NodePort makes the service available on the same port on each Kubernetes node. The NGINX Plus Ingress Controller for Kubernetes is a great way to expose services inside Kubernetes to the outside world, but you often require an external load balancing layer to manage the traffic into Kubernetes nodes or clusters. The nginxdemos/hello image will be pulled from Docker Hub. Scale the service up and down and watch how NGINX Plus gets automatically reconfigured. The NGINX-LB-Operator watches for these resources and uses them to send the application‑centric configuration to NGINX Controller. F5, Inc. is the company behind NGINX, the popular open source project. Look what you’ve done to my Persian carpet,” you reply. Privacy Notice. Last month we got a Pull Request with a new feature merged into the Kubernetes Nginx Ingress Controller codebase. Copyright © F5, Inc. All rights reserved.Trademarks | Policies | Privacy | California Privacy | Do Not Sell My Personal Information, Ebook: Cloud Native DevOps with Kubernetes, NGINX Microservices Reference Architecture, Configuring NGINX Plus as an External Load Balancer for Red Hat OCP and Kubernetes, Getting Started with NGINX Ingress Operator on Red Hat OpenShift, certified collection for NGINX Controller, VirtualServer and VirtualServerRoutes resources. We declare those values in the webapp-svc.yaml file discussed in Creating the Replication Controller for the Service below. As we know NGINX is one of the highly rated open source web server but it can also be used as TCP and UDP load balancer. Documentation explaining how to configure NGINX and NGINX Plus as a load balancer for HTTP, TCP, UDP, and other protocols. In this tutorial, we will learn how to setup Nginx load balancing with Kubernetes on Ubuntu 18.04. We put our Kubernetes‑specific configuration file (backend.conf) in the shared folder. Load the updates to your NGINX configuration by running the following command: # nginx -s reload Option - Run NGINX as Docker container. If the service is configured with the NodePort ServiceType, then the external Load Balancer will use the Kubernetes/OCP node IPs with the assigned port. Instead of installing NGINX as a package on the operating system, you can rather run it as a Docker container. Using the "externalIPs" array works but is not what I want, as the IPs are not managed by Kubernetes. All of your applications are deployed as OpenShift projects (namespaces) and the NGINX Plus Ingress Controller runs in its own Ingress namespace. We run this command to change the number of pods to four by scaling the replication controller: To check that NGINX Plus was reconfigured, we could again look at the dashboard, but this time we use the NGINX Plus API instead. We use those values in the NGINX Plus configuration file, in which we tell NGINX Plus to get the port numbers of the pods via DNS using SRV records. I’m told there are other load balancers available, but I don’t believe it  . Accept cookies for analytics, social media, and advertising, or learn more and adjust your preferences. We discussed this topic in detail in a previous blog, but here’s a quick review: nginxinc/kubernetes-ingress – The Ingress controller maintained by the NGINX team at F5. I am working on a Rails app that allows users to add custom domains, and at the same time the app has some realtime features implemented with web sockets. Now we’re ready to create the replication controller by running this command: To verify the NGINX Plus pod was created, we run: We are running Kubernetes on a local Vagrant setup, so we know that our node’s external IP address is 10.245.1.3 and we will use that address for the rest of this example. In my Kubernetes cluster I want to bind a nginx load balancer to the external IP of a node. We configure the replication controller for the NGINX Plus pod in a Kubernetes declaration file called nginxplus-rc.yaml. With this type of service, a cluster IP address is not allocated and the service is not available through the kube proxy. They’re on by default for everybody else. For high availability, you can expose multiple nodes and use DNS‑based load balancing to distribute traffic among them, or you can put the nodes behind a load balancer of your choice. Analytics cookies are off for visitors from the UK or EEA unless they click Accept or submit a form on nginx.com. LBEX works like a cloud provider load balancer when one isn't available or when there is one but it doesn't work as desired. When the Service type is set to LoadBalancer, Kubernetes provides functionality equivalent to type equals ClusterIP to pods within the cluster and extends it by programming the (external to Kubernetes) load balancer with entries for the Kubernetes pods. This feature request came from a client that needs a specific behavior of the Load… The resolve parameter tells NGINX Plus to re‑resolve the hostname at runtime, according to the settings specified with the resolver directive. This allows the nodes to access each other and the external internet. It is important to note that the datapath for this functionality is provided by a load balancer external to the Kubernetes cluster. This deactivation will work even if you later click Accept or submit a form. The operator configures an external NGINX instance (via controller) to Load Balance onto a Kubernetes Service. NGINX Ingress Controller for Kubernetes. When all services that use the internal load balancer are deleted, the load balancer itself is also deleted. NGINX-LB-Operator enables you to manage configuration of an external NGINX Plus instance using NGINX Controller’s declarative API. So we’re using the external IP address (local host in … # kubectl create service nodeport nginx … Kubernetes Ingress with Nginx Example What is an Ingress? The LoadBalancer solution is supported only by certain cloud providers and Google Container Engine and not available if you are running Kubernetes on your own infrastructure. Unfortunately, Nginx cuts web sockets connections whenever it has to reload its configuration. NGINX and NGINX Plus integrate with Kubernetes load balancing, fully supporting Ingress features and also providing extensions … Uncheck it to withdraw consent. With NGINX Plus, there are two ways to update the configuration dynamically: We assume that you already have a running Kubernetes cluster and a host with the kubectl utility available for managing the cluster; for instructions, see the Kubernetes getting started guide for your cluster type. You can report bugs or request troubleshooting assistance on GitHub. Creating an Ingress resource enables you to expose services to the Internet at custom URLs (for example, service A at the URL /foo and service B at the URL /bar) and multiple virtual host names (for example, foo.example.com for one group of services and bar.example.com for another group). So we’re using the external IP address (local host in this case) and a … Download the excerpt of this O’Reilly book to learn how to apply industry‑standard DevOps practices to Kubernetes in a cloud‑native context. Your Cookie Settings Site functionality and performance. powered by Disqus. The API provides a collection of resource definitions, along with Controllers (which typically run as Pods inside the platform) to monitor and manage those resources. As we’ve used a load balanced service in k8s in Docker Desktop they’ll be available as localhost:PORT: – curl localhost:8000 curl localhost:9000 Great! comments Now we make it available on the node. Rather than list the servers individually, we identify them with a fully qualified hostname in a single server directive. On the host where we built the Docker image, we run the following command to save the image into a file: We transfer nginxplus.tar to the node, and run the following command on the node to load the image from the file: In the NGINX Plus container’s /etc/nginx folder, we are retaining the default main nginx.conf configuration file that comes with NGINX Plus packages. Writing an Operator for Kubernetes might seem like a daunting task at first, but Red Hat and the Kubernetes open source community maintain the Operator Framework, which makes the task relatively easy. Ignoring your attitude, Susan proceeds to tell you about NGINX-LB-Operator, now available on GitHub. This tutorial shows how to run a web application behind an external HTTP(S) load balancer by configuring the Ingress resource. It’s rather cumbersome to use NodePortfor Servicesthat are in production.As you are using non-standard ports, you often need to set-up an external load balancer that listens to the standard ports and redirects the traffic to the :. A merged configuration from your definition and current state of the Ingress controller is sent to NGINX Controller. You can manage both of our Ingress controllers using standard Kubernetes Ingress resources. Our pod is created by a replication controller, which we are also setting up. If we refresh this page several times and look at the status dashboard, we see how the requests get distributed across the two upstream servers. Its declarative API has been designed for the purpose of interfacing with your CI/CD pipeline, and you can deploy each of your application components using it. Your option for on-premise is to … Kubernetes Ingress Controller - Overview. NGINX will be configured as Layer 4 load balancer (TCP) that forwards connections to one of your Rancher nodes. Before you begin. We can check that our NGINX Plus pod is up and running by looking at the NGINX Plus live activity monitoring dashboard, which is available on port 8080 at the external IP address of the node (so http://10.245.1.3:8080/dashboard.html in our case). To get the public IP address, use the kubectl get service command. I’m using the Nginx ingress controller in Kubernetes, as it’s the default ingress controller and it’s well supported and documented. I am trying to set up a metalLB external load balancer with the intention to access an nginx pod from outside the cluster using a publicly browseable IP address. Using Kubernetes external load balancer feature¶ In a Kubernetes cluster, all masters and minions are connected to a private Neutron subnet, which in turn is connected by a router to the public network. We also declare the port that NGINX Plus will use to connect the pods. The diagram shows a sample deployment that includes just such an operator (NGINX-LB-Operator) for managing the external load balancer, and highlights the differences between the NGINX Plus Ingress Controller and NGINX Controller. To neatly format the JSON output, we pipe it to jq. An ingress controller is responsible for reading the ingress resource information and processing it appropriately. NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 192.0.2.1 443/TCP 2h sample-load-balancer LoadBalancer 192.0.2.167 80:32490/TCP 6s When the load balancer creation is complete, will show the external IP address instead. Please note that NGINX-LB-Operator is not covered by your NGINX Plus or NGINX Controller support agreement. kubectl --namespace ingress-basic get services -o wide -w nginx-ingress-ingress-nginx-controller When it comes to Kubernetes, NGINX Controller can manage NGINX Plus instances deployed out front as a reverse proxy or API gateway. Many controller implementations are expected to appear soon, but for now the only available implementation is the controller for Google Compute Engine HTTP Load Balancer, which works only if you are running Kubernetes on Google Compute Engine or Google Container Engine. This will allow the ingress-nginx controller service’s load balancer, and hence our services, … Refer to your cloud provider’s documentation. We are putting NGINX Plus in a Kubernetes pod on a node that we expose to the Internet. With this service-type, Kubernetes will assign this service on ports on the 30000+ range. In this tutorial, we will learn how to setup Nginx load balancing with Kubernetes on Ubuntu 18.04.
