This is a basic docker-gen template for nginx load balancing a docker swarm cluster.
This aim to provide a strong load balancer configuration, outside docker.
Based on @jwilder work on https://github.com/jwilder/nginx-proxy
Only support http ATM.
Tested on debian 8, nginx 1.6.2, docker-gen 0.7.1, swarm 1.2.3, docker 1.11.2
Run it:
docker-gen --watch -only-published --notify "nginx -s reload" --endpoint tcp://<swarm-ip>:<swarm-port> nginx.tmpl /etc/nginx/sites-enabled/default
Then start your containers using labels:
- virtual host:
labels=lb.vhost=your-vhost.com - container port:
labels.lb.servicePort=1234, default 80
Container port MUST be published (randomly is better).
See docker-compose.yml for a demo.
This is a POC, feel free to comment.
