The thing I dislike most about Nginx is that if you are using it as a reverse proxy for like 20 containers and one of them is up, the whole web server will refuse to start up:
nginx: [emerg] host not found in upstream "my-app"
Obviously making 19 sites also unavailable just because one of them is caught in a crash loop isn't ideal. There is a workaround involving specifying variables, like so (non-Kubernetes example, regular Nginx web server running in a container, talking to other containers over an internal network, like Docker Compose or Docker Swarm):
location / {
resolver 127.0.0.11 valid=30s; # Docker DNS
set $proxy_server my-app;
proxy_pass http://$proxy_server:8080/;
proxy_redirect default;
}
Sadly, if you try to use that approach, then you just get:
nginx: [emerg] "proxy_redirect default" cannot be used with "proxy_pass" directive with variables
Sadly, switching the redirect configuration away from the default makes some apps go into a redirect loop and fail to load: mostly legacy ones, where Firefox shows something along the lines of "The page isn't redirecting properly". It sucks especially badly if you can't change the software that you just need to run and suddenly your whole Nginx setup is brittle. Apache2 and Caddy don't have such an issue.
That's to say that all software out there has some really annoying failure modes, even is Nginx is pretty cool otherwise.
