Hi @tspicer , how to prevent nginx to cache wordpress pages when i'm logged as administrator?
i'm using the php configuration with redis, in many cases when i visit any site page, the cache save also the wp admin toolbar header , by visiting in incognito i can see the cached wp admin toolbar.
I see also you wordpress dedicated git, this config will fix my problem? can i use you installer in any vps ?

@Able2Code how did you solve the 502 issue? have the same problem

[tspicer]

Since this is an NGINX (not Wordpress) repo, I will do my best to assist.

It is hard to troubleshoot these errors given the variations of configs. I'm happy to help, but please post configs for NGINX and wordpress. For example, in NGINX you can set it to not cache anything /wp-admin*. Also, if you have a WP installer you are using, please share that as well.

Hi,
I noticed you set your PROXY address to your PHP service. Is there a reason you are directing NGINX to connect to PHP as a PROXY? You have NGINX_PROXY_UPSTREAM: wp:9000. I would normally expect a reverse proxy to be internal, so something like NGINX_PROXY_UPSTREAM=localhost:8080

The docs dig into this: https://github.com/openbridge/nginx#digging-into-the-env-file

Take a look at where this setting is used: https://github.com/openbridge/nginx/tree/master/conf/php/nginx/upstream.d

In a nutshell, it appears you are treating the proxy and php-fpm as the same thing. Maybe this is a typo?

I can envision certain configurations where the PROXY is a different connection, but this is an advanced setup. Also, you may want to try using this container for PHP-FPM: https://github.com/openbridge/ob_php-fpm

It affords more flexibility and is optimized for this WP.

[tspicer]

In nginx.conf notice the upstream includes are distinct for each service. If PHP and PROXY are the same, I'm not sure how it would work properly.

upstream php-fpm      {include /etc/nginx/upstream.d/php-fpm.conf;}
upstream proxy      {include /etc/nginx/upstream.d/proxy.conf;}
upstream redis     {include /etc/nginx/upstream.d/redis.conf;}

@tspicer changed NGINX_PROXY_UPSTREAM to localhost:8080 and that made it work
i can't wrap my head around it at the moment but i'll read some more docs to understand how it really works

thank you!

awesome, glad to hear.
