host not found in up stream #127
Description
I'm trying to run nginx as a reverse proxy inside docker. The issue is that nginx is exiting because it doesn't find the host in upstream (nginx strts faster than keycloak I assume) so it just exits.
docker compose
version: '2'
services:
keycloak:
image: jboss/keycloak-postgres
ports:
- "8080:8080"
nginx:
build:
context: ./nginx
dockerfile: dockerfile
ports:
- "80:80"
- "443:443"
depends_on:
- keycloak
entrypoint: ['sleep', '25']
> nginx conf
server {
listen 80;
location / {
index index.html;
root /usr/share/nginx/html;
}
location /auth {
proxy_pass http://keycloack:8080/auth;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
