最近在学习nginx
目标是:x想通过docker中的nginx容器1转发到 nginx2的页面中，目前转发失败，--name mynignx的log报错如下
2023/09/15 16:15:55 [error] 22#22: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 172.168.0.1, server: localhost, request: "GET / HTTP/1.1", upstream: "http://172.168.0.2:90/", host: "localhost:89"请问一下应该如何应对呢？
创建了两个目录，导入了相关配置文件以及映射。
mynignx
docker run --name mynignx --net mynet -e TZ="Asia/Shanghai" -d -p 89:80 -v /usr/local/docker/nginx/html:/usr/share/nginx/html -v /usr/local/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /usr/local/docker/nginx/conf.d:/etc/nginx/conf.d -v /usr/local/docker/nginx/log:/var/log/nginx nginx
mynignx2
docker run --name mynignx2 --net mynet -e TZ="Asia/Shanghai" -d -p 90:80 -v /usr/local/docker/nginx2/html:/usr/share/nginx2/html -v /usr/local/docker/nginx2/conf/nginx.conf:/etc/nginx/nginx.conf -v /usr/local/docker/nginx2/conf.d:/etc/nginx/conf.d -v /usr/local/docker/nginx/log:/var/log/nginx nginx
创建了一个network 包含了这俩容器。
docker network inspect mynet

问题补充：
测试容器的连通性
docker exec 172.168.0.2 ping 172.168.0.3
Error response from daemon: No such container: 172.168.0.2
docker exec mynignx ping mynignx2
OCI runtime exec failed: exec failed: unable to start container process: exec: "ping": executable file not found in $PATH: unknown
docker exec mynignx curl mynignx2返回的是mynignx2的html页面数据说明是连通的

改为--net=host ，模式
配置了两个映射，
http://test.player3.cn 映射到 本地localhsot
http://dev.player3.cn 映射到 本地localhsot
docker run --name mynignx --net=host -e TZ="Asia/Shanghai" -d -v /usr/local/docker/nginx/html:/usr/share/nginx/html -v /usr/local/docker/nginx/conf/nginx.conf:/etc/nginx/nginx.conf -v /usr/local/docker/nginx/conf.d:/etc/nginx/conf.d -v /usr/local/docker/nginx/log:/var/log/nginx nginx
docker run --name mynignx2 --net=host -e TZ="Asia/Shanghai" -d -v /usr/local/docker/nginx2/html:/usr/share/nginx/html -v /usr/local/docker/nginx2/conf/nginx.conf:/etc/nginx/nginx.conf -v /usr/local/docker/nginx2/conf.d:/etc/nginx/conf.d -v /usr/local/docker/nginx2/log:/var/log/nginx nginx
mynignx的conf
server {
listen 80;
server_name test.player3.cn;
#access_log /var/log/nginx/host.access.log main;
location / {
proxy_pass http://dev.player3.cn:90/;
## root /usr/share/nginx/html;
## index index.html index.htm;
}
}
mynignx2的conf
server {
listen 90;
server_name dev.player3.cn;
#access_log /var/log/nginx/host.access.log main;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
}
问题虽然解决了，但是是属于换了其他的网络模式访问的，这个上面问题还是没有根除掉，希望大佬解惑一下。
