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, Mike17KViews0likes15Commentsdoes 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 again9.7KViews0likes5CommentsDoes NGINX Controller allow the creation of upstream server groups/farms configuraton components?
Hello, After looking at many videos and articles I didn't see an option to define the upstream server groups/farms that an Application Component should use and I am starting to think that the Nginx Controller GUI and API can't be used for managing the sever farm definitions. There is a new option called snippets or using the Nginx Instance Manager but this is strange to me that this seems to have not been added in the Nginx Controller GUI/API as this way the configuration will be validated or I am wrong about this? https://docs.nginx.com/nginx-controller/app-delivery/manage-apps/ https://docs.nginx.com/nginx-controller/app-delivery/about-snippets/Solved2.3KViews0likes1CommentConfig 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 ? ThanksSolved1.7KViews1like4CommentsKnowledge 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??

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?576Views0likes1CommentProblems with CSS and JS with Docker

I faced a problem with especially 14.1 and nginx 1.14.0-0ubuntu1.2 Test Setup I have is set accordingly; Vmware Workstation 15 (Lan segmentation choose and vlan setup on ubuntus and F5) F5 V14.1 Vm edition Flow is ; Client VLAN ------ F5 ----- Server VLAN Client vlan there is test vm ubuntu 18.04.2 and server vlan there is another test vm ubuntu 18.04.2 When I test sytem with serverside installed with nginx 1.14.0-0ubuntu1.2 and setted everything default test page. and set F5 with all default values as node, pool, vserver http vserver all works normally.But the big thing is F5 never closes connection session table whatsoever when backend is nginx 1.14.0-0ubuntu1.2 version when i purge nginx and install apache2 this behaviour never occurs. I dont know if its F5 connection handling or nginx out of standart approach on tcp stack. Apache benchmark tool i use enough to fill the session table entries easily since never expires (no conn limit on vserver all default) $ ab -n 5000 -c 50 http://20.0.0.10/ After this command finished i try to request the vserver ip again and always gives can not establish connection. When i try curl via locally inside F5 device vserver is working. But not over network. When i check session table in F5; These entries below all i see even the client and server machines are powered down. F5's session table is still with those and incrementing the timeout values even i set the timeout to 30 seconds. 20.0.0.200:50862 20.0.0.10:80 any6.any any6.any tcp 255 (tmm: 1) none none 20.0.0.200:60550 20.0.0.10:80 any6.any any6.any tcp 254 (tmm: 1) none none 20.0.0.200:44070 20.0.0.10:80 any6.any any6.any tcp 253 (tmm: 1) none none Last work i had done on 12.x i have no issue with nginx this version. There is something not right Between nginx and F5 need to check more. Please write if anyone face such issue as i doo. For fast solution i try to clear sessions since you can not delete them when tried. Only option to restart device or bigstart restart I dont know if its a known bug. Please guide me to url if its i could not able to find info regarding. Thanks474Views0likes2Comments
