Consul Commands (CLI)
Consul is controlled via a very easy to use command-line interface (CLI).
Consul is only a single command-line application: consul. This application
then takes a subcommand such as "agent" or "members". The complete list of
subcommands is in the navigation to the left.
The Consul CLI is a well-behaved command line application. In erroneous
cases, a non-zero exit status will be returned. It also responds to -h and --help
as you'd most likely expect. And some commands that expect input accept
"-" as a parameter to tell Consul to read the input from stdin.
To view a list of the available commands at any time, just run consul with
no arguments:
$ consul
usage: consul [--version] [--help] <command> [<args>]
Available commands are:
agent Runs a Consul agent
event Fire a new event
exec Executes a command on Consul nodes
force-leave Forces a member of the cluster to enter the "left" state
info Provides debugging information for operators
join Tell Consul agent to join cluster
keygen Generates a new encryption key
leave Gracefully leaves the Consul cluster and shuts down
members Lists the members of a Consul cluster
monitor Stream logs from a Consul agent
reload Triggers the agent to reload configuration files
version Prints the Consul version
watch Watch for changes in Consul
To get help for any specific command, pass the -h flag to the relevant
subcommand. For example, to see help about the join subcommand:
$ consul join -h
Usage: consul join [options] address ...
Tells a running Consul agent (with "consul agent") to join the cluster
by specifying at least one existing member.
Options:
-rpc-addr=127.0.0.1:8400 RPC address of the Consul agent.
-wan Joins a server to another server in the WAN pool
