Nginx Emerg Host Not Found In Upstream Docker
vote 17 down vote favorite 6 We have several rails apps under common domain in docker, and we use nginx to direct requests to specific apps. our_dev_server.com/foo # proxies to foo app our_dev_server.com/bar # proxies to bar Config looks like this: upstream foo { server foo:3000; } upstream bar { server bar:3000; } # and about 10 more... server { listen *:80 default_server; server_name our_dev_server.com; location /foo { # this host not found in upstream localhost is specific to asset management in rails dev rewrite ^/foo/assets(/.*)$ /assets/$1 break; rewrite ^/foo(/.*)$ /foo/$1 break; proxy_pass http://foo; } location /bar { rewrite ^/bar/assets(/.*)$ /assets/$1 break; rewrite ^/bar(/.*)$ /bar/$1 break; proxy_pass http://bar; } # and about 10 more... } If one of these apps is not started then nginx fails and stops: host not found in upstream "bar:3000" in /etc/nginx/conf.d/nginx.conf:6 We dont't need them all to be up but nginx fails otherwise. How to make nginx ignore failed upstreams? nginx rewrite proxypass share|improve this question asked Sep 29 '15 at 13:47 Jack Watson 308515 Are you linking the app containers with the Nginx containers, or running them separate from each other? If the host within the upstream block doesn't resolve, at runtime, then Nginx will exit with the above error... –Justin Sep 29 '15 at 14:03 If you can use an IP then it'll start-up fine. Would using resolver (nginx.org/en/docs/http/ngx_http_core_module.html#resolver) work in your case? –Justin Sep 29 '15 at 14:05 Is the startup order of the containers causing the issue? –Justin Sep 29 '15 at 14:39 @Justin we have each app in separate container, nginx too. Link them with docker –Jack Watson Sep 29 '15 at 14:42 @Justin

So far with links there were no problems with nginx connecting to my php5-fpm fastcgi server located in a different server in one group http://stackoverflow.com/questions/33639138/docker-networking-nginx-emerg-host-not-found-in-upstream via docker-compose. Newly though when I run docker-compose --x-networking up my php-fpm, mongo and nginx containers boot up, however nginx quits straight away with [emerg] 1#1: host not found in upstream "waapi_php_1" in /etc/nginx/conf.d/default.conf:16 However, if I run the docker-compose command again while the php and mongo containers are running (nginx exited), nginx starts and works fine from then on. This is my docker-compose.yml file: nginx: image: nginx ports: - "42080:80" volumes: - ./config/docker/nginx/default.conf:/etc/nginx/conf.d/default.conf:ro php: build: config/docker/php ports: - "42022:22" volumes: - .:/var/www/html env_file: config/docker/php/.env.development mongo: image: mongo ports: - "42017:27017" volumes: - /var/mongodata/wa-api:/data/db command: --smallfiles This is my default.conf for nginx: server { listen 80; root /var/www/test; error_log /dev/stdout debug; access_log /dev/stdout; location / { # try to serve file directly, fallback to app.php try_files $uri /index.php$is_args$args; } location ~ ^/.+\.php(/|$) { # Referencing the php service host (Docker) fastcgi_pass waapi_php_1:9000; fastcgi_split_path_info ^(.+\.php)(/.*)$; include fastcgi_params; # We must reference the document_root of the external server ourselves here. fastcgi_param SCRIPT_FILENAME /var/www/html/public$fastcgi_script_name; fastcgi_param HTTPS off; } } How can I get nginx to work with only a single docker-compose call? nginx docker docker-compo
