我有一个node.js应用程序(web-app)和两个流明应用程序(api,customer-api),它们由在端口80上监听的nginx容器进行负载平衡。
我的docker-compose.yml文件:
version: '2'
services:
nginx:
build:
context: ../
dockerfile: posbytz-docker/nginx/dockerfile
volumes:
- api
- customer-api
ports:
- "80:80"
networks:
- network
depends_on:
- web-app
- api
- customer-api
web-app:
build:

dockerfile: posbytz-docker/web-app-dockerfile
volumes:

由于我使用的是桥接网络,因此能够使用容器名称从另一个容器访问每个容器。但是我想要的是使用其nginx配置的server_name访问容器。
下面是每个应用程序的nginx配置,
web-app.conf:
server {
listen 80;
server_name posbytz.local;
resolver 127.0.0.11 valid=10s;
location / {
proxy_pass http://web-app:3004;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
api.conf:
server {
listen 80;
index index.php index.html;
root /var/www/api/public;
server_name api.posbytz.local;
resolver 127.0.0.11 valid=10s;
location / {
try_files $uri /index.php?$args;
}
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass api:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
customer-api.conf
server {
listen 80;
index index.php index.html;
root /var/www/customer-api/public;
server_name customer-api.posbytz.local;
resolver 127.0.0.11 valid=10s;
location / {
try_files $uri /index.php?$args;
}
location ~ \.php$ {
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass customer-api:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
我想从Web应用程序容器访问api和customer-api容器。问题是当我尝试curl http://nginx
时,我只是从api容器中得到响应。有什么方法可以通过Nginx容器访问customer-api容器?
当我手动将nginx容器(172.21.0.9)的IP及其各自的server_name映射到Web应用容器的/ etc / hosts文件中时,它似乎可以工作。
我在Web应用程序容器的/ etc / hosts文件中添加的内容:
172.21.0.9 api.posbytz.local
172.21.0.9 customer-api.posbytz.local
还有其他方法可以在没有人工干预的情况下实现这一目标吗?

最后通过更改customer-api.conf上的nginx配置使其在端口81上侦听来使其工作。 listen 80;
至listen 81;
。现在http://nginx
解析为http://api:9000
,而http://nginx:81
解析为http://customer-api:9000
答案 1 :(得分:0)
您可以使用别名:
networks:
some-network:
aliases:
- api.posbytz.local
- customer-api.posbytz.local
