【问题描述】：
我有一个运行 docker 的 CentOS 服务器，带有 3 个容器和 NGINX。开放的端口是 80、443 和 22。容器的端口如下：
- 集装箱 A：9000
- 集装箱 B：4201
- 容器 C：5443
每个 NGINX 配置文件几乎完全相同：
/etc/nginx/conf.d/A.conf
server {
listen 80;
server_name A.local;
return 301 https://A.local$request_uri;
}
server {
listen 443 ssl;
server_name A.local;
ssl_certificate ...;
ssl_certificate_key ...;
location / {
proxy_pass http://127.0.0.1:9000;
}
}
文件之间唯一改变的是 A 到 B、A 到 C 以及 127.0.0.1 之后的端口号。
现在，当我浏览到 A.local（位于我本地机器上的 /etc/hosts 中）时，我得到了一个自签名的 ssl，我接受，我得到了正确的网站！一个作品！
浏览到 B.local，我得到一个自签名的 ssl，我接受，我得到 502 bad gateway...
浏览到 C.local，我得到一个自签名的 ssl，我接受，我得到 502 bad gateway...
当我转到 192.168.1.247:4201 时，我得到了正确的网站，容器运行正常，我可以直接访问它，nginx 没有正常通过。

【问题讨论】：
-
你能发布
docker ps的输出吗？您是否通过nginx -T确认一切都按照nginx中的例外情况运行？ -
在你发布的 nginx -T 的输出中，所有proxy_pass都指向proxy_pass 127.0.0.1:4201；没有端口 9000 或 5443。
-
@LucaG 这是我的问题中的错字，我已修复。
nginx -T的输出显示它们是不同的端口。 -
如果你在运行 nginx 的同一台主机上执行 wget -q -O- 127.0.0.1:4201，你会得到错误还是正确的输出？
-
@lucaG，9000 得到了我期望的 HTML，4201 给了我正在运行的 crate 容器上的 JSON，5443 给了我期望的 HTML。 JSON 有点奇怪，因为通过我的浏览器访问它可以获得预期的界面，但是它似乎正在工作。
