AWS ECS Docker – nginx：没有在上游find主机

我试图使用docker在AWS ECS上运行一个php + mysql应用程序。 应用程序堆栈由一个mysql，elk，php-fpm和nginx docker容器组成。 这些容器都运行在同一个docker机器上。 当任务启动时，nginx容器退出时出现以下错误： nginx：[emerg]主机在/etc/nginx/conf.d/upstream.conf:1的上游“php：9001”中找不到 。

Nginx的Dockerfile：

FROM alpine:3.4 RUN apk add --update nginx #Clear Cache and Temp Data RUN rm -rf /var/cache/apk/* && rm -rf /tmp/* ADD nginx.conf /etc/nginx/ ADD symfony.conf /etc/nginx/conf.d/ RUN echo "upstream php-upstream { server php:9001; }" > /etc/nginx/conf.d/upstream.conf RUN adduser -D -g '' -G www-data www-data CMD ["nginx"] EXPOSE 80 EXPOSE 443 

RUN echo“upstream php-upstream {server php：9001;}”> /etc/nginx/conf.d/upstream.conf

php:9001部分引用了在AWS ECS任务定义中定义的php容器。

nginx.conf：

 user www-data; worker_processes 4; pid /run/nginx.pid; events { worker_connections 2048; multi_accept on; use epoll; } http { server_tokens off; sendfile on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 15; types_hash_max_size 2048; include /etc/nginx/mime.types; default_type application/octet-stream; access_log off; error_log off; gzip on; gzip_disable "msie6"; include /etc/nginx/conf.d/*.conf; include /etc/nginx/sites-enabled/*; open_file_cache max=100; } daemon off; 

symfony.conf：

 server { server_name _; root /var/www/symfony/web; location / { try_files $uri @rewriteapp; } location @rewriteapp { rewrite ^(.*)$ /app.php/$1 last; } location ~ ^/(app|app_dev|config)\.php(/|$) { fastcgi_pass php-upstream; fastcgi_split_path_info ^(.+\.php)(/.*)$; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param HTTPS off; } error_log /var/log/nginx/symfony_error.log; access_log /var/log/nginx/symfony_access.log; } 

/etc/php7/php-fpm.conf：

 [symfony] user = nobody group = nobody listen = 0.0.0.0:9001 pm = dynamic pm.max_children = 1000 pm.start_servers = 1 pm.min_spare_servers = 1 pm.max_spare_servers = 3 env[DB_1_ENV_MYSQL_DATABASE] = $DB_1_ENV_MYSQL_DATABASE env[DB_1_ENV_MYSQL_USER] = $DB_1_ENV_MYSQL_USER env[DB_1_ENV_MYSQL_PASSWORD] = $DB_1_ENV_MYSQL_PASSWORD catch_workers_output = yes 

我也尝试改变监听listen = /var/run/php-fpm/php-fpm.sock或listen = 127.0.0.1:9001与对nginxconfiguration的相应变化，但这导致了各种其他的错误消息。

我没有在php和nginx容器之间设置AWS ECS任务定义内的链接。

要设置容器的链接，请转到“networking设置”，然后在“链接”字段中input链接。
