海外TECH	DEV Community	Full Stack Kubernetes with Kong Ingress Controller	https://dev.to/mbogan/full-stack-kubernetes-with-kong-ingress-controller-hm3	Full Stack Kubernetes with Kong Ingress ControllerKubernetes has become the name of the game when it comes to container orchestration It allows teams to deploy and scale applications to meet changes in demand while providing a great developer experience The key to handling modern dynamic scalable workloads in Kubernetes is a networking stack that can deliver API management a service mesh and an ingress controller Kong Ingress Controller allows users to manage the routing rules that control external user access to the service in a Kubernetes cluster from the same platform This article will look at how you can use Kong for full stack application deployments with Kubernetes By full stack we mean Kong can handle Containers Container networking Pod networking Service networking Host networking Load balancing Rate limiting HTTPS redirectsLet s get started by creating our cluster Installing Kind KubernetesWith Kind you can run local Kubernetes clusters using Docker It was designed for testing Kubernetes but is perfect for local K development like we will do in this example There are quite a few ways to install Kind depending on your operating system If you have a Mac you can install it quickly with Homebrew brew install kindIf you are on a Windows machine and have Chocolatey installed the command is just as simple choco install kindIf you have Go and Docker installed you can run the following command to install kind GOMODULE on go get sigs ks io kind v For more installation options see the Kind quickstart Once Kind is installed you need to create a cluster kind create clusterAfter making the cluster you can interact with it using kubectl To list your clusters run kind get clustersIt should return kind the default cluster context name Now run the following to point kubectl to the kind cluster kind export kubeconfigIf you set up Kind correctly running the following command will give you details about your cluster kubectl cluster info Installing Kong Ingress ControllerNow that we have a cluster running we can install Kong quickly by applying the manifest directly with the following command kubectl create f Now run the following command to get details on kong proxy kubectl n kong get service kong proxyYou will notice that the external IP is still pending Kind only exposes the Kubernetes API endpoint and so the service is not accessible outside of the cluster Since we are using Kind we will have to run a port forward to do this This command does not get daemonized so you will have to open another console window to run other commands kubectl n kong port forward address localhost svc kong proxy Next we need to set an environment variable with the IP address from where we want to access Kong This will be localhost since we are using a port forward export PROXY IP localhost You can curl the IP now or visit in a browser and should see message no Route matched with those values Deploying an Example AppNow let s deploy something that will return some results Kubernetes has multiple example applications available in a Github repo We are going to deploy the Guestbook App with these commands kubectl apply f kubectl apply f kubectl apply f kubectl apply f Now if we run kubectl get services we will see two new services We can also query the pods to make sure their status is Running kubectl get pods l app kubernetes io name guestbook l app kubernetes io component frontendTo test it you can run another port forward really quick with kubectl port forward svc frontend You will find the guestbook running at http localhost We will now set up the Kong Ingress Controller Expose the App to the InternetNow we can use the Kong Ingress Controller so we need to set up a resource to serve traffic We can create a proxy for our application with the following command echo apiVersion networking ks io vkind Ingressmetadata name guestbook annotations konghq com strip path true kubernetes io ingress class kongspec rules http paths path pathType Prefix backend service name frontend port number kubectl apply f Now you will see the guestbook app at http localhost Using Plugins as Services in KongWith Kong Ingress we can execute plugins on the service level That way Kong will execute a plugin whenever a request is sent to a specific service no matter which ingress path from where it came If we want to add rate limits to our app we can add the rate limiting plugin to our Kubernetes installation with the following command echo apiVersion configuration konghq com vkind KongPluginmetadata name rl by ipconfig minute limit by ip policy localplugin rate limiting kubectl apply f kongplugin configuration konghq com rl by ip createdOnce you install the plugin you can apply the konghq com plugins annotation on our Guestbook with the following command kubectl patch svc frontend p metadata annotations konghq com plugins rl by ip n If you curl the guestbook app you will see that rate limiting has been set up If you plan on testing the Guestbook frequently during this example you may want to set the limit higher or you will run into a Kong error that says the rate limit has been exceeded Configuring an HTTPS RedirectSo far the app is running on HTTP and we want it to run on HTTPS If we want to tell Kong to redirect all the HTTP requests we can update its annotations to HTTPS and issue a redirect with this command to patch the ingress entry kubectl patch ingress guestbook p metadata annotations konghq com protocols https konghq com https redirect status code To test this using kind set up another port forward with the following command kubectl n kong port forward address localhost svc kong proxy You can now access a secure version of the guestbook at https localhost It will not have a certificate so you will run into warnings in your browser Let s look at how we can add certificates Adding the Cert ManagerYou can install the cert manager with the following command kubectl apply f Once the images pull down you can verify that it is running with this command kubectl get all n cert managerYou should see something like this Since we have Kubernetes running locally with a port forward the IP address for the Kong proxy is If you weren t using a port forward you could run the following command to find the IP address kubectl get o jsonpath status loadBalancer ingress ip service n kong kong proxyBut since we are using a port forward this command will return nothing If this were in production you would then set up DNS records to resolve your domain to the IP address you just retrieved Once that is done you can request a certificate from Let s Encrypt by running the following making sure to change the email echo apiVersion cert manager io valphakind ClusterIssuermetadata name letsencrypt prod namespace cert managerspec acme email user example com change this email privateKeySecretRef name letsencrypt prod server solvers http ingress class kong kubectl apply f Next you will have to update your ingress resource to provide a certificate with the following command changing the domain to your own echo apiVersion networking ks io vkind Ingressmetadata name guestbook example com annotations kubernetes io tls acme true cert manager io cluster issuer letsencrypt prod kubernetes io ingress class kongspec tls secretName guestbook example com hosts demo example com change this domain subdomain rules host demo example com change this domain subdomain http paths path pathType Prefix backend service name guestbook port number kubectl apply f Once that is updated the cert manager will start to provision the certificate and the certificate will be ready soon Missing a Tool in Your Ks Stack Kong may be the missing tool in your Kubernetes stack Kong Ingress Controller can implement authentication HTTPS redirects security certificates and more across all your Kubernetes clusters Using Kong you can control your containers networking load balancing rate limiting and more from one platform It truly is the choice for full stack ingress deployments	2021-06-28 17:19:02
