consul agent -dev #leave this running consul members
consul members -detailed
consul members -http-addr=localhost:8500 $ consul
Usage: consul [--version] [--help] <command> [<args>]
# means only new version have this function
Available commands are:
agent Runs a Consul agent
#catalog Interact with the catalog
#connect Interact with Consul Connect
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.
#intention Interact with Connect service intentions
join Tell Consul agent to join cluster
keygen Generates a new encryption key
keyring Manages gossip layer encryption keys
kv Interact with the key-value store
leave Gracefully leaves the Consul cluster and shuts down
lock Execute a command holding a lock
maint Controls node or service maintenance mode
members Lists the members of a Consul cluster
monitor Stream logs from a Consul agent
operator Provides cluster-level tools for Consul operators
reload Triggers the agent to reload configuration files
rtt Estimates network round trip time between nodes
#services Interact with services
snapshot Saves, restores and inspects snapshots of Consul server state
validate Validate config files/directories
version Prints the Consul version
watch Watch for changes in Consulconsul agent -h
==> Usage: consul agent [options]
Starts the Consul agent and runs until an interrupt is received. The
agent represents a single node in a cluster.
Command Options
-advertise=<string>
Sets the advertise address to use.
-advertise-wan=<string>
Sets address to advertise on WAN instead of -advertise address.
-atlas=<string>
(deprecated) Sets the Atlas infrastructure name, enables SCADA.
-atlas-endpoint=<string>
(deprecated) The address of the endpoint for Atlas integration.
-atlas-join
(deprecated) Enables auto-joining the Atlas cluster.
-atlas-token=<string>
(deprecated) Provides the Atlas API token.
-bind=<string>
Sets the bind address for cluster communication.
-bootstrap
Sets server to bootstrap mode.
-bootstrap-expect=<int>
Sets server to expect bootstrap mode.
-client=<string>
Sets the address to bind for client access. This includes RPC, DNS,
HTTP and HTTPS (if configured).
-config-dir=<value>
Path to a directory to read configuration files from. This
will read every file ending in '.json' as configuration in this
directory in alphabetical order. This can be specified multiple
times.
-config-file=<value>
Path to a JSON file to read configuration from. This can be
specified multiple times.
-data-dir=<string>
Path to a data directory to store agent state.
-dc=<string>
Datacenter of the agent (deprecated: use 'datacenter' instead).
-dev
Starts the agent in development mode.
-disable-host-node-id
Setting this to true will prevent Consul from using information
from the host to generate a node ID, and will cause Consul to
generate a random node ID instead.
-dns-port=<int>
DNS port to use.
-domain=<string>
Domain to use for DNS interface.
-encrypt=<string>
Provides the gossip encryption key.
-http-port=<int>
Sets the HTTP API port to listen on.
-join=<value>
Address of an agent to join at start time. Can be specified
multiple times.
-join-wan=<value>
Address of an agent to join -wan at start time. Can be specified
multiple times.
-log-level=<string>
Log level of the agent.
-node=<string>
Name of this node. Must be unique in the cluster.
-node-id=<string>
A unique ID for this node across space and time. Defaults to a
randomly-generated ID that persists in the data-dir.
-node-meta=<key:value>
An arbitrary metadata key/value pair for this node, of the format
`key:value`. Can be specified multiple times.
-non-voting-server
(Enterprise-only) This flag is used to make the server not
participate in the Raft quorum, and have it only receive the data
replication stream. This can be used to add read scalability to
a cluster in cases where a high volume of reads to servers are
needed.
-pid-file=<string>
Path to file to store agent PID.
-protocol=<int>

Ignores a previous leave and attempts to rejoin the cluster.
-retry-interval=<string>
Time to wait between join attempts.
-retry-interval-wan=<string>
Time to wait between join -wan attempts.
-retry-join=<value>
Address of an agent to join at start time with retries enabled. Can
be specified multiple times.
-retry-join-ec2-region=<string>
EC2 Region to discover servers in.
-retry-join-ec2-tag-key=<string>
EC2 tag key to filter on for server discovery.
-retry-join-ec2-tag-value=<string>
EC2 tag value to filter on for server discovery.
-retry-join-gce-credentials-file=<string>
Path to credentials JSON file to use with Google Compute Engine.

Address of an agent to join -wan at start time with retries
enabled. Can be specified multiple times.
-retry-max=<int>
Maximum number of join attempts. Defaults to 0, which will retry
indefinitely.
-retry-max-wan=<int>
Maximum number of join -wan attempts. Defaults to 0, which will
retry indefinitely.
-serf-lan-bind=<string>
Address to bind Serf LAN listeners to.
-serf-wan-bind=<string>
Address to bind Serf WAN listeners to.
