Hello,
I have a nginx proxy in front of systemd-nspawn containers.
The IP's of the containers are dynamic.
When I start nginx *after* the containers it works.
When the IP of the container is changed while nginx is running i get a
"Bad Gateway" error.
The config looks like:
server {
server_name foobar.example.com
...
location / {
resolver 127.0.0.53 valid=10s;
...
proxy_pass http://container;
}
}
nginx is 1.1.18 so it should work as documented in
http://nginx.org/en/docs/http/ngx_http_core_module.html#resolver
The workaround there
https://stackoverflow.com/questions/42720618/docker-nginx-stopped-emerg-11-host-not-found-in-upstream/52319161#52319161
doesn't work.
I have also try to config a upstream backend and the resolver in the
server part or in the http part.
The errors are: "upstream timed out" or "container could not be resolved
(3: Host not found)"
Whats wrong there?
Best Regards
