I’ve a dockker compose file to start an nginx on a VM ( RHEL 7 )
But when I leave out the network_mode:host, the OS is not listening at port 80.
Only when I set it to “host” the nginx is accessible.
I don’t know why this is necessary. Is this VM specific ?
---
version: '2'
services:
nginx:
# network_mode: host
restart: always
container_name: nginx
image: nginx:1.13
logging:
driver: "json-file"
options: {
"max-size":"5m",
"max-file":"3"}
expose:
- '80'
ports:
- '80:80'
volumes:
- '/app/nginx/conf/nginx.conf:/etc/nginx/nginx.conf:ro'
This is the nginx config:
upstream xap_e2esi {
server xap_e2esi:8080;
}
server {
listen 80;
auth_basic off;
allow all;
location /e2esi/ {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass http://xap_e2esi/;
}
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
