Я пытаюсь создать многоконтейнерную установку на основе докеров с обратным прокси-сервером для обслуживания нескольких доменов, где веб-сайты, базы данных и обратный прокси-сервер на основе nginx работают в контейнерах, но я не знаю, что мне не хватает ( Я новичок в nginx).
Подробности:
my_example_domain_1.com
, my_example_domain_2.net
Мой пример: (на основе их: multi-container
)
nginx_revproxy / default.conf:
server {
listen 80;
server_name localhost;
location / {
root /usr/share/nginx/html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
server {
listen 80;
server_name my_example_domain_1.com;
location / {
proxy_pass http://wp1:80;
}
}
server {
listen 80;
server_name my_example_domain_2.net;
location / {
proxy_pass http://wp2:80;
}
}

Примечания:
revproxy
из docker-compose.yml
файл и выполнить docker-compose up -d
на моем настольном компьютере я могу получить доступ к обоим веб-сайтам (без revproxy) через порты контейнера: localhost:8081
, localhost:8082
docker-compose up -d
на моем сервере веб-сайты недоступны$ docker ps -a

Есть у кого-нибудь идеи?
А пока разобрался сам ..
Это рабочая конфигурация (если кому интересно будущее):
nginx_revproxy/default.conf
:
upstream domain1 {
server wp1:80;
}
upstream domain2 {
server wp2:80;
}
server {
listen 80;
server_name domain1.com;
location / {
proxy_pass http://domain1/;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
}
}
server {
listen 80;
server_name domain2.com;
location / {
proxy_pass http://domain2/;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
}
}
