ELB Consul

This Docker image allows you to (de)register EC2 instances belonging to a specific Consul service with an Amazon Elastic Load Balancer (ELB).

Usage

The elb-consul image takes all of its configuration from environment variables.

• AWS_ACCESS_KEY_ID ... Your AWS access key
• AWS_SECRET_ACCESS_KEY ... Your AWS secret key
• AWS_REGION ... The AWS region that your load balancer is located in
• ELB_NAME ... The exact name of your load balancer
• CONSUL_SERVER ... The IP:PORT to connect to the Consul server (eg: 172.1.6.1.2:8500)
• CONSUL_SERVICE ... The exact name of the Consul service you want to monitor

You could run only one instance of elb-consul per ELB_NAME / CONSUL_SERVICE pair but for high availability purpose, it is recommanded to run two of them. Internally the Docker image uses a Consul Lock to make sure that only one elb-consul will be active at anytime.
