A extended docker image for nginx, configurable trough env variables. This can be easily used with docker-compose.
This image can handle locations and multiple upstreams per location. The upstream config is entirely at you disposal however for now the location is just autogenerated.
Build the image then you can use it in docker-compose as follows:
loadbalancer:
image: dynginx
environment:
NGINX_PORT: "80"
SERVICE_1: "location1:server upstream:9999"
SERVICE_2: "location2:server upstream:9122/server upstream2:9122"
ports:
- '80:80'
this will generate the following nginx config:
user nginx;
worker_processes 1;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}
daemon off;
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
#tcp_nopush on;
keepalive_timeout 65;
#gzip on;
server {
listen 80;
location /location1 {
proxy_pass http://upstreamlocation1/location1;
}
location /location2 {
proxy_pass http://upstreamlocation2/location2;
}
}
upstream upstreamlocation1 {
server upstream:9999;
}
upstream upstreamlocation2 {
server upstream:9122;
server upstream2:9122;
}
}
O course you'll also have to make sure you can connect to the upstreams also.
The container can take up to 5 services specified independently but it can take many many more if you just make sure to separate each service by a comma "," within the service variable:
SERVICE_1: "location1:server upstream:8070,location2:server upstream:8081/server upstream2:8081"
Also make sure that every upstream line is divided by "/"
