Question
Not sure why I can't access my web servers (Ubuntu server on Hyper-V) from host OS (Windows)
My environment: Host OS with Hyper-V Ubuntu Server.
I am running 5 containers (2 DB, 2 Wordpress, 1 NGINX). Here is everything I setup and the NGINX config output. I followed these steps from another dev.
**I created the docker network for NGINX FYI before I ran NGINX.
NGINX YML:
version: "3"
services:
nginx-proxy:
image: jwilder/nginx-proxy
container_name: nginx-proxy
ports:
- "80:80"
volumes:
- /var/run/docker.sock:/tmp/docker.sock:ro
networks:
default:
external:
name: nginx-proxy
1st wordpress YAML:
bain@wordpress:/home/hakase/multi-wp/reagan$ cat docker-compose.yml
version: "3"
services:
reagan-website:
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: PASSWORD
MYSQL_DATABASE: db2
MYSQL_USER: wordpress2
MYSQL_PASSWORD: PASSWORD
container_name: wordpress_db2
wordpress:
depends_on:
- reagan-website
image: wordpress:latest
expose:
- 80
restart: always
environment:
VIRTUAL_HOST: blog.reagan.localhost
WORDPRESS_DB_HOST: reagan-website:3306
WORDPRESS_DB_USER: wordpress2
WORDPRESS_DB_PASSWORD: PASSWORD
container_name: wordpress2
volumes:
db_data:
networks:
default:
external:

2nd wordpress YAML:
bain@wordpress:/home/hakase/multi-wp/reagan$ cat /home/hakase/multi-wp/zack/docker-compose.yml
version: "3"
services:
zack-website:
image: mysql:5.7
volumes:
- db_data:/var/lib/mysql
restart: always
environment:
MYSQL_ROOT_PASSWORD: PASSWORD
MYSQL_DATABASE: db1
MYSQL_USER: wordpress1
MYSQL_PASSWORD: PASSWORD
container_name: wordpress_db1
wordpress:
depends_on:
- zack-website
image: wordpress:latest
expose:

restart: always
environment:

container_name: wordpress1

My docker conainters running after executing the three YML files:

Looks like everything is setup correctly, but I can’t access via domain name. I can’t do it by IP since NGINX looks for request from port 80 and if it matches the domain, it forwards the request to the wordpress domain. Since in containers, the IPs are internal to the docker bridged network.
I added the eth0 IP and domain names to SYSTEM32/Drivers/Hosts and can ping using the local domain names. But through the browser, nothing. But NGINX is running because I get a 503 error using the actual server IP.
But If i create a single webserver not using NGINX, I can access it by IP:8080. But hosting several wesites, that’s not feasible. Please help me. 20 hours deep and can’t figure it out.
