我正在尝试使用Docker Compose容器化与我的Web应用程序相关的所有内容,包括Nginx和SSL证书。为此,我正在使用Nginx Proxy image from JWilder和LetsEncrypt Companion,但是在使Nginx代理正常工作时遇到了麻烦,结果最终是:
Nginx 502错误的网关
[错误] 31160#0:* 35连接到上游时,connect()失败(111:连接被拒绝),客户端:xx.xx.xx.xx,服务器:domain.com,请求:“ GET / dev / HTTP / 1.1”,上游:“ webapp://127.0.0.1:8080”,主机:“ domain.com”
这仅在尝试设置Nginx代理和SSL证书时发生,因此我知道这是这两个容器中一个或两个的配置问题。如果有人能发现我要去哪里错了,我将万分感谢!
以下是有问题的容器:
version: '3.1'

mywebapp:

depends_on:

webapp:
container_name: webapp
build: ./env/webapp
hostname: webapp
networks:

ports:
- 9000:9000
- 8080:8080
volumes:

要点:
Nginx代理服务器配置:
upstream webapp {
server 127.0.0.1:8080;
}
server {
listen 80;
listen [::]:80;
server_name webapp.localhost;
location / {
proxy_pass http://webapp;
}
}
server {
# SSL configuration
listen 443 ssl http2;
listen [::]:443 ssl http2;
ssl_certificate certs/default.crt;
ssl_certificate_key certs/default.key;
include /etc/nginx/global/ssl-params.conf;
server_name webapp.localhost;
location / {
proxy_pass http://webapp;
}
}
Webapp Web服务器配置:
server {
listen 8080;
listen [::]:8080;
server_name webapp.localhost;
root /home/www/webapp/src;
index index.php;
include /etc/nginx/defaults/php.conf;
location / {
try_files $uri $uri/ /index.php$is_args$args;
}
}
访问http://webapp.localhost:8080时,我可以看到webapp Web服务器为该页面提供服务没有问题,因此我怀疑Nginx代理服务器配置有问题。
感谢阅读。
答案 0 :(得分:2)
由于nginx和webapp位于两个单独的容器上,因此nginx无法通过为上游配置的本地主机(127.0.0.1)上的webapp:
upstream webapp {
server 127.0.0.1:8080;
}
将其更改为webapp:8080
。
