kubernetes-ingress VS istio

Everything in the YAML snippets below — except for ingress configuration — relates to configuring the NGINX ingress controller. This includes customizing the default configuration.

In these examples, I assume that users have deployed an nginx-ingress-controller to their cluster through the eks layer. This controller is responsible for creating an nlb and exposing Elasticsearch and Kibana to the internet through their ingresses.

Now, you need to install the Nginx Ingress Controller so that it can redirect incoming requests to your payment app to use HTTPS. Since you've exposed the app using nodePort, you need to install the Ingress using a custom value file that specifies the service type to NodePort.

Kubernetes We have a kubernetes cluster which has a dropwizard based web application running as a service. This application has a rest uri to upload files. It cannot upload files larger than 1MB. I get the following error: ERROR [2017-07-27 13:32:47,629] io.dropwizard.jersey.errors.LoggingExceptionMapper: Error handling a request: ea812501b414f0d9! com.fasterxml.jackson.core.JsonParseException: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')! at [Source: ! 413 Request Entity Too Large! ! 413 Request Entity Too Large! nginx/1.11.3! ! Hide resultsI have tried the suggestions given in https://github.com/nginxinc/kubernetes-ingress/issues/21. I have edited the Ingress to set the proxy-body-size annotation. Also, I have tried using the configMap without any success. we are using kubernetes version 1.5. Please let me know if you need additional information.

The example below shows how to configure a canary deployment using Nginx Ingress. The custom annotations used here are specific to Nginx:

This: https://kubernetes.github.io/ingress-nginx/ Not this: https://docs.nginx.com/nginx-ingress-controller/

So far, i've been following the example here to set up an nginx Ingress Controller and some test services behind it. However, I am unable to follow Step 6 which displays the external IP for the node that the load balancer is running on as my node does not have an ExternalIP in the addresses section, only a LegacyHostIP and InternalIP.

Also, of personal note, I highly recommend you use the "ingress-nginx" controller which has a huge community and is of much higher quality and flexibility than the "nginx-ingress controller by nginx inc". I've had a lot of success with dozens of clients with this controller. It rocks!

For example, the ingress project from NGINX has its own CRDs that give better control over service versions and blue/green and canary cutovers https://github.com/nginxinc/kubernetes-ingress/tree/v3.0.0/examples/custom-resources/traffic-splitting

Istio is a popular open-source service mesh framework that provides a comprehensive solution for managing, securing, and observing microservices-based applications running on Kubernetes.

Leverage a service mesh like Istio or Linkerd to manage communication between microservices within the Kubernetes cluster. These service meshes can be configured to intercept JMX traffic and enforce access control policies. Benefits:

Open Source and Cloud Computing: A Match Made in Heaven The cloud is accelerating OSS adoption. Cloud-native technologies like Kubernetes [https://kubernetes.io/] and Istio [https://istio.io/], both open-source projects, are revolutionizing how applications are built and deployed across cloud platforms.

Consider the case of Bookinfo, a sample application provided by Istio, rewritten using CloudWeGo's Kitex for superior performance and extensibility.

It is a dedicated infrastructure layer that manages service-to-service communication, providing features like load balancing, encryption, authentication, and monitoring. Istio deploys sidecar proxies alongside each microservice instance. These proxies handle communication, providing features like load balancing, service discovery, encryption, monitoring and authentication.

5Y old post that sounds like they've done similar here: Caddy Issue Istio Issue but doesn't cover much of the implementation

In a production environment there will be a load balancer setup with an Ingress Controller, Service Mesh or some type of Custom Router. This allows all traffic to be sent to the single load balancer IP address and then route the traffic to a service based on the Domain name or subpath. We are using a NGINX ingress controller but service meshes like Istio have been becoming the most popular solution to use as they offer more segmentation, security and granular control.

Flagger is a progressive delivery tool that enables a Kubernetes operator to automate the promotion or rollback of deployments based on metrics analysis. It supports a variety of metrics including Prometheus, Datadog, and New Relic to name a few. It also works well with Istio service mesh, and can implement progressive traffic splitting between primary and canary releases.

End-to-end data encryption with a service mesh: Using an end-to-end data encryption mechanism with a service mesh like Istio, TLS can secure communication between different microservices within a Kubernetes cluster. This is a popular approach for modern, distributed microservice architectures.
