我是 Windows 版 docker 的新手，并且有这样的设置，其中 2 个存储库都有自己的 docker-compose.yml 文件。一个是API，另一个是APP。
API docker-compose.yml
version: '3'
networks:
my_network:
name: my_network
ipam:
config:
- subnet: 172.23.0.0/24
services:
my_api:
build:
context: .
dockerfile: .docker/site.dockerfile
container_name: my_api
ports:
- 127.0.12.9:80:80
volumes:
- ./:/var/www/html
networks:
my_network:
aliases:
- "api.localhost"
webserver:
image: nginx:alpine
container_name: webserver_my_api
restart: unless-stopped
tty: true
ports:
- 127.0.12.10:80:80
- 127.0.12.10:443:443
volumes:
- ./:/var/www/html
- ./.docker/nginx/conf.d/:/etc/nginx/conf.d/
networks:
- my_network
APP docker-compose.yml
version: '3'
networks:
my_network:
external: true
services:
my_app:
build:
context: .
dockerfile: .docker/site.dockerfile
container_name: my_app
ports:
- 127.0.12.11:80:80
volumes:
- ./:/var/www/html
networks:
my_network:
aliases:
- "app.localhost"
webserver:
image: nginx:alpine
container_name: webserver_my_app
restart: unless-stopped
tty: true
ports:
- 127.0.12.12:80:80
- 127.0.12.12:443:443
volumes:
- ./:/var/www/html
- ./.docker/nginx/conf.d/:/etc/nginx/conf.d/
networks:
- my_network
每个都有自己的 docker 文件。
API和APP都有相同的.docker/site.dockerfile
FROM php:7.4-fpm
USER root
WORKDIR /var/www/html
# just a bunch of RUN commands to install PHP dependencies
EXPOSE 9000
CMD ["php-fpm"]
API 的 Nginx 配置 .docker/nginx/conf.d/app.conf
server {
listen 80;
index index.php index.html;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /var/www/html/public;
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass my_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;
}
location / {
try_files $uri $uri/ /index.php?$query_string;
gzip_static on;
}
}
然后是APP的Nginx conf .docker/nginx/conf.d/app.conf
server {
listen 80;
index index.php index.html;
error_log /var/log/nginx/error.log;
access_log /var/log/nginx/access.log;
root /var/www/html/public;
location ~ \.php$ {
try_files $uri =404;
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_pass my_app:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
location / {
try_files $uri $uri/ /index.php?$query_string;
gzip_static on;
}
}
之后，我将这些行添加到我的 Windows 主机文件中。
127.0.12.10 api.localhost
127.0.12.12 app.localhost
http://api.localhost 和 http://app.localhost 都能够在我的网络浏览器上运行。但是，当APP向API发出curl请求时，出现以下错误。
cURL 错误 7:无法连接到 api.localhost 端口 80:连接被拒绝(请参阅 https://curl.haxx.se/libcurl/c/libcurl-errors.html)http://api .localhost
当我执行docker network inform my_network时，两者都驻留在同一网络中。

"MacAddress": "02:42:ac:17:00:05",
"IPv4Address": "172.23.0.5/24",
"IPv6Address": ""
}
},
我也可以通过 postman 提出请求，没有任何问题。就是APP对API做curl的时候。
我错过了什么吗？
谢谢

添加了 docker ps 命令的屏幕截图
最佳答案
经过数小时的反复试验，我找到了答案。
在我的例子中，我没有使用别名，而是使用了容器上设置的 IPv4。
为了获取 IPv4，我运行了 docker network inform my_network，它给了我这个列表。
"Containers": {
"0d77c5cc22c36f8086eb8e5d580562354c4c6b3c7bdd962e0f8cebfa7a3d844b": {
"Name": "my_api",
"EndpointID": "93bb1cd93ccd09b7c1fd2de3e074525b2fc98919eba0cf2cc96c2112d4e1e1b5",
"MacAddress": "02:42:ac:17:00:09",
"IPv4Address": "172.23.0.9/24",
"IPv6Address": ""
},
"53432448ea91677c643d2f1ff206dcfdc6209741ba9951da342756f752672ab8": {
"Name": "webserver_my_app",
"EndpointID": "09ec9ae65461bcc42a750fb0a4fee8305b299c1ad2f1b8e16c65902119489b0d",
"MacAddress": "02:42:ac:17:00:03",
"IPv4Address": "172.23.0.3/24",
"IPv6Address": ""
},
"55c2fef084b249a7b3537c641c7101276d9130c6d81d77b21e88206bd10001ec": {
"Name": "webserver_my_api",
"EndpointID": "ad1d3b1bedd140a26aec05de276f6f5edc0631b22fa2e77595f5bdf63d9eabca",
"MacAddress": "02:42:ac:17:00:08",
"IPv4Address": "172.23.0.8/24",
"IPv6Address": ""
},
"dedfe7f75ef76e913b4483708b9920b7d94f8d4931db74e9831cc86194113d75": {
"Name": "my_app",
"EndpointID": "80f2c8e1b83817dda62c682f9ed8e098d8cd3cf4c6d05b3af145e58660368779",
"MacAddress": "02:42:ac:17:00:05",
"IPv4Address": "172.23.0.5/24",
"IPv6Address": ""
}
},
由于 webserver_my_api 是我的 nginx 容器，因此我使用其 IP 地址 172.23.0.8。然后我在我的应用程序上运行 curl_setopt($cURLConnection, CURLOPT_URL, 'http://172.23.0.8'); 现在它可以工作了!!!
虽然这个解决方案有效，但我仍然不认为它是实际的解决方案。这样做的问题是，当我重新启动容器时，这些 IP 地址将会改变。
对此有什么长期解决方案吗？另外，我仍然想使用 api.localhost 而不是 IP 地址。
谢谢
