Using with NGINX

[jclusso]

Was looking into MRSK and was wondering how using NGINX would work? Our application relies on NGINX in front since we have some Lua scripts. I was wondering if anyone has added NGINX yet? Seems like it would kinda be redundant to Traefik?

We've been weaning ourselves off Nginx where we can, moving to app middleware, Traefik plugins, or load balancer and CDN features.

If you aren't using nginx as a reverse proxy to your app, you could explore running it as an accessory and routing specific paths to it with Traefik. If you are using it as a proxy, you'd need to extend MRSK to create and run images on a Docker network so your nginx container could proxy to the app using its container name.

Your best bet is to assess whether you can live without those Lua scripts or migrate them to another layer, like Traefik or a fronting CDN.

Interesting, I’ll have to investigate if we could run them some other way.

The purpose is really to offload a slow running request to poll Redis for job completion. We have a 30s timeout on specific API requests that run a worker that processes this and puts the result in Redis.

any update on how to use cloudflare to serve static parts? I don't really like to install nginx if I can serve all the assets directly from a CDN like cloudflare

[jclusso]

Not sure this is relevant. You can already use CloudFlare to serve static parts without NGINX.

@PabloC we have 4 apps deployed on AWS with MRSK and our typical schema now to serve static parts is Rails -> AWS ALB -> AWS CloudFront. No need for Nginx at all. Seems like you can build the same solution with CloudFlare.

[PabloC]

do you update your AWS CloudfFront assets at build time? is something you do in the DockerFile? Tks!

[igor-alexandrov]

No, CloudFront has ALB configured as an origin. In this case if any asset is missing in CloudFront (after new build has been deployed) it will be fetched through ALB from Rails.
