kubernetes-ingress VS njs

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:

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

This article came at an interesting timing for me, since I recently started to explore building my own CDN node on top of NGINX open source inspired by this article from Fly: https://fly.io/blog/the-5-hour-content-delivery-network/

I've worked with nginx in the past, and didn't have a great experience, so I was apprehensive diving in, but this time was very different. I think njs (their custom JS scripting environment) was a game changer. Support is built in to nginx core, and available by default in their docker containers, so it's much easier to get started with than Lua scripting. Their JS feature support has some quirks (no optional chaining, array destructuring, console.log's don't show up in logs, are some examples of things that threw me off) but overall nothing that blocked me from implementing the functionality I needed, and the integration points within the nginx config felt fairly natural.

I did run into a number of things that were locked behind their commercial offering that made me a bit uncomfortable betting on it for the long term compared to purely open source alternatives. Off the top of my head:

- DNS discovery. There's a thread on the Fly example repo accompanying the blog post that describes the use case and proposes some workarounds: https://github.com/fly-apps/nginx-cluster/issues/2. Life would be a lot simpler if DNS discovery from the commercial offering was just available (i.e. we can outright delete a brittle bash script that makes DNS queries and reloads nginx on a 5 second interval). This was mentioned in the article as something they're planning to open source.

- Access to some kind of shared key-value store for custom caching logic in njs scripts. With Lua we could just connect to Redis, but njs can't seem to establish persistent network connections for now, so that's off the table. This wasn't mentioned in the article, but they did mention in this Github issue that they're planning on open sourcing their keyval module for this use case: https://github.com/nginx/njs/issues/437. I have some use cases where being able to connect to Redis would be ideal, since syncing keyval across a cluster seems to be eventually consistent (https://docs.nginx.com/nginx/admin-guide/high-availability/z...), but for most of my caching use cases it should be sufficient.

So this article, along with their overall willingness to work with the community to identify and bring commercial features into open source (at least from what I've observed across their responses to Github issues) does a lot to alleviate those concerns.

Though at the end of the day, I don't necessarily need every nginx feature to be in open source. I have no problems with paying for great software like nginx to support its development. But as a small bootstrapped founder, their current pricing structure (from what I could gather on the internet is ~ 2k-5k per running instance), is completely prohibitive. It'd probably require a revamp to the way they sell the software (i.e. self-serve onboarding and automatic license provisioning for smaller customers instead of having customers of all sizes go through expensive sales people), but I'd love to see a more progressive pricing structure with a lower barrier to entry for their commercial product.

I'd leave guys a bug at github: https://github.com/nginx/njs .
