Usage: consul peering generate-token [options] -name <peer name>
|
|
|
|
Generate a peering token. The name provided will be used locally by
|
|
this cluster to refer to the peering connection. Re-generating a token
|
|
for a given name will not interrupt any active connection, but will
|
|
invalidate any unused token for that name.
|
|
|
|
Example:
|
|
|
|
$ consul peering generate-token -name west-dc
|
|
|
|
Example using a load balancer in front of Consul servers:
|
|
|
|
$ consul peering generate-token -name west-dc -server-external-addresses load-balancer.elb.us-west-1.amazonaws.com:8502
