Consul Nginx

This Docker container is setup to run Nginx with Consul for service discovery and health monitoring.

It has also been optimized to run on Joyent's Triton, however it will always also support strait Docker and boot2docker.

Running

It can be run on its own simply via:

docker run -d  -p 8400 -p 8500 -p 8600 --name consul progrium/consul -server -bootstrap -ui-dir /ui
docker run -d --name lb1 --link consul:consul corbinu/consul-nginx

docker exec -it lb1 nginx-bootstrap

Consul will UI will be available on port mapped to 8500
