The `join` command tells a Consul agent to join an existing cluster. A new
|
|
Consul agent may join any node in the existing cluster. After joining with one
|
|
member, the gossip communication will propagate the updated membership state
|
|
across the cluster.

# Consul Join
|
|
|
|
Command: `consul join`
|
|
|
|
The `join` command tells a Consul agent to join an existing cluster.
|
|
A new Consul agent may join any node in the existing cluster. After joining
|
|
with one member, the gossip communication will propagate the updated membership
|
|
state across the cluster.
|
|
|
|
An agent which is already part of a cluster may join an agent in a different
|
|
cluster, causing the two clusters to be merged into a single cluster.
|
|
|
|
## Usage
|
|
|
|
Usage: `consul join [options] address ...`
|
|
|
|
You may call join with multiple addresses if you want to try to join
|
|
multiple clusters. Consul will attempt to join all addresses, and the join
|
|
command will fail only if Consul was unable to join with any.
