Automatic Cluster Formation Using Consul

One FlowG node can discover other FlowG nodes automatically if Consul is configured to be used.

In order to enable automatic cluster formation, have an instance of Consul running on the network.

Start the FlowG server with --consul-url flag set to the address of the Consul node. For example:

flowg-server \
  --syslog-proto="tcp" \
  --syslog-tls \
  --syslog-tls-cert="/path/to/cert.pem" \
  --syslog-tls-key="/path/to/cert.key" \
  --syslog-tls-auth \
  --consul-url="localhost:8500"

Alternatively, automatic cluster formation can also be enabled by using an environment variable. Set an environment variable CONSUL_URL to the address of the Consul node.
