I'm trying to figure out how to use nginx proxy cache with some specific rules. For exemple, when i'm hosting Ghost or Wordpress, I don't want to cache admin section. Using server snippet, I've tried a lot of different combinaison but still have issues with cache in admin section.
nginx.ingress.kubernetes.io/proxy-buffering: "on"
nginx.ingress.kubernetes.io/server-snippet: |-
proxy_ignore_headers X-Accel-Expires Expires Cache-Control;
proxy_ignore_headers Set-Cookie;
proxy_cache app_cache;
proxy_cache_lock on;
proxy_cache_valid any 30m;
add_header X-Cache-Status $upstream_cache_status;
I want to use nginx code snippet for (ghost|sinout) paths to bypass cache when in admin area, but i'm loosing the proxy_pass context resulting to a 502 bad gateway.
Here is the current ingress config caching every pages, admin path too:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/proxy-buffering: "on"
nginx.ingress.kubernetes.io/server-snippet: |-
proxy_cache my_blog_cache;
proxy_cache_lock on;
proxy_cache_valid any 30m;
add_header X-Cache-Status $upstream_cache_status;
proxy_ignore_headers X-Accel-Expires Expires Cache-Control;
name: my-blog
namespace: web
spec:
rules:
- host: blog.example.com
http:
paths:
- backend:
serviceName: ingress-541322b8660dbd2ceb1e8ff1813f0dd5

path: /
tls:

secretName: my-blog-cert

Here is the nginx config i'm trying to get but not compatible with ingress annotations:
location / {
proxy_cache my_blog_cache;
proxy_cache_valid 200 30m;
proxy_cache_valid 404 1m;
proxy_pass http://ghost_upstream;
proxy_ignore_headers X-Accel-Expires Expires Cache-Control;
proxy_ignore_headers Set-Cookie;
proxy_hide_header Set-Cookie;
proxy_hide_header X-powered-by;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
expires 10m;
}
location /content/images {
alias /path/to/ghost/content/images;
access_log off;
expires max;
}
location /assets {
alias /path/to/ghost/content/themes/uno-master/assets;
access_log off;
expires max;
}
location /public {
alias /path/to/ghost/core/built/public;
access_log off;
expires max;
}
location /ghost/scripts {
alias /path/to/ghost/core/built/scripts;
access_log off;
expires max;
}
location ~ ^/(?:ghost|signout) {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_pass http://ghost_upstream;
add_header Cache-Control "no-cache, private, no-store, must-revalidate, max-stale=0, post-check=0, pre-check=0";
}
Thanks for your help !
