How to rewrite a path to a backend service dropping the prefix and passing the remaining path?
Hello, I am not sure whether my posting is appropriate in this area, so please delete it if there is a violation of posting rules... This must be a common task, but I cannot figure out how to do the following fanout rewrite in our nginx ingress: http://abcccc.com/httpbin/anything-> /anything (the httpbin backend service) When I create the following ingress with a path of '/' and send the query, I receive a proper response. curl -I -k http://abczzz.com/anything apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: mikie-ingress namespace: mikie spec: ingressClassName: nginx rules: - host: abczzz.com http: paths: - path: / pathType: Prefix backend: service: name: httpbin-service port: number: 8999 What I really need is to be able to redirect to different services off of this single host, so I changed the ingress to the following, but the query always fails with a 404. Basically, I want the /httpbin to disappear and pass the path onto the backend service, httpbin. curl -I -k http://abczzz.com/httpbin/anything apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: mikie-ingress namespace: mikie annotations: nginx.ingress.kubernetes.io/rewrite-target: /$2 spec: ingressClassName: nginx rules: - host: abczzz.com http: paths: - path: /httpbin(/|$)(.*) pathType: Prefix backend: service: name: httpbin-service port: number: 8999 Thank you for your time and interest, Mike
does nginx (1.20 or newer) re-resolve DNS for proxy_pass?
Consider this nginx config snippet: location ^~ /_example/ { proxy_pass https://example.com/_example/; proxy_set_header Host my-site; } Assuming "example.com" DNS TTL is set to 60 seconds - will nginx re-resolve DNS after 60 seconds? Or does it only resolve the name on startup? I'm finding different info around the internet: - it will re-resolve only in the commercial nginx plus - it will re-resolve only in newer nginx releases; in older ones, one need to make some workarounds - it will only resolve once on startup and never again
Config NGINX to F5
Hi everyone, I have VS. NGINX require script to implement at F5 profile but i dont know where I must config at F5 configuration. Here the NGINX requirement : client_max_body_size 5000M; client_body_buffer_size 5000M; client_body_timeout 4024; client_header_timeout 3024; Where I must config that NGINX requirement to the VS in F5 ??? Using profile or irules ?? How to set up ? ThanksKnowledge sharing: Containers, Kubernetes, Openshift, F5 Container Connector, NGINX Ingress
For anyone interested about the free traning for "F5 Container Connector for Kubernetes" or "F5 OpenShift Container Integration" at "LearnF5". For NGINX being installed in Kubernetes there is enough info but for F5 Contaner Connector/Container Ingress Services there is not so much: https://docs.nginx.com/nginx-ingress-controller/f5-ingresslink/ https://www.nginx.com/products/nginx-ingress-controller/ https://community.f5.com/t5/technical-articles/better-together-f5-container-ingress-services-and-nginx-plus/ta-p/280471 F5 Devcentral also has youtube channel with usefull info: https://www.youtube.com/c/devcentral If you don't have good knowledge about containers and kubernetes then first check the links below.

Hii Everyone, Can i ask about converting NGINX script to iRules F5? I have a NGINX script : [root@webdplk conf.d]# cat simponi.conf server { listen 80; listen 443; server_name dplk.bni.co.id; location / { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_pass http://192.168.3.187; } location /mobile { rewrite /mobile(.*) /$1 break; proxy_pass http://192.168.3.186:7005/; } } server { listen 7005; server_name dplk.bni.co.id; location / { rewrite /mobile(.*) /$1 break; proxy_pass http://192.168.3.186:7005/; } } [root@webdplk conf.d]# How if that script if convert to F5 IRules?? Thankyouu
NGINX Migration, Rewrite Profile: Is there another way?
We are migrating, as part of a project, a big NGINX implementation to an F5. Basically, it would assume the role of a reverse proxy. The two biggest things the NGINX does are: Translating from external hosts (www.example.com) to internal hosts (www.example.local) Load balancing between different back-end servers, depending on the URI. For the first point: There are a BUNCH of translations. We're using a rewrite profile. Sometimes, www.example.com/ translates to www.example.local/, and www.example.com/app1/ translates to www.example2.com/app1. And, on a single rewrite profile, there are, I think, more than 50 rules. Is there a better way of doing this? Should we really modify back-end servers to accept both hosts, external and internal? And, how do we deal with URI's with no trailing slash? If they have none, it won't match the rewrite rule. Should we add 301 respond to each and every URI? The second: Should we use policies or iRules? I've got to confess, we have already big iRules, separated with procs and the like. So, migrating that to policies would be a pain in the ass. EDIT: One more question: We have different client side URL, that need to be rewritten to the same server. www.example.com/app1 and www.example.com/app2 to www.example.local/. However, for some reason, rewrite profile does not allow for this. How can we achieve it?
Problems with CSS and JS with Docker
Hi! I'm having some problems deploying a dynamic website via Docker with Nginx. It seems that everything in my configuration is okay because it deploys correctly but my website does not apply my CSS or JS files. Also, i have to say that the images i have on directories below do apply correctly. Can anyone help me please? Thank you.Nginx is only redirecting to port 8080
I have a .net 8 solution multiple APIs and I'm using docker and Nginx to host the application. please find below the full details: Dockerfile FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base WORKDIR /app EXPOSE 8080 FROM mcr.microsoft.com/dotnet/sdk:8.0 AS build ARG BUILD_CONFIGURATION=Release ...

If I switch the port on those same projects than API2 loads normally and API1 stops loading. I've been trying all kinds of stuff over last 2 days and nothing seems to work. Those same projects with the same configuration were working perfectly when I was using .net 6 with the same nginx version, but when I upgraded the project to .net 8 it broke. I need your help and suggestions. Anything will be helpfull.
