Consul Members

Command: consul members

Corresponding HTTP API Endpoint: [GET] /v1/agent/members

The members command outputs the current list of members that a Consul agent knows about, along with their state. The state of a node can only be "alive", "left", or "failed".

Nodes in the "failed" state are still listed because Consul attempts to reconnect with failed nodes for a certain amount of time in the case that the failure is actually just a network partition.

The table below shows this command's required ACLs. Configuration of blocking queries and agent caching are not supported from commands, but may be from the corresponding HTTP endpoint.

ACL Required
node:read

Usage

Usage: consul members [options]

Command Options

  • -detailed - If provided, output shows more detailed information about each node.

  • -segment Enterprise - The segment to show members in. If not provided, members in all segments visible to the agent will be listed.

  • -status - If provided, output is filtered to only nodes matching the regular expression for status

  • -wan - For agents in Server mode, this will return the list of nodes in the WAN gossip pool. These are generally all the server nodes in each datacenter.

  • -filter=<filter> - Expression to use for filtering the results, e.g., -filter='Tags["dc"] == dc2'. See the /catalog/nodes API documentation for a description of what is filterable.

Enterprise Options

  • -partition=<string> - Specifies the partition to query. If not provided, the partition will be inferred from the request's ACL token, or will default to the default partition. Partitions are a Consul Enterprise feature added in v1.11.0.

API Options

  • -ca-file=<value> - Path to a CA file to use for TLS when communicating with Consul. This can also be specified via the CONSUL_CACERT environment variable.

  • -ca-path=<value> - Path to a directory of CA certificates to use for TLS when communicating with Consul. This can also be specified via the CONSUL_CAPATH environment variable.

  • -client-cert=<value> - Path to a client cert file to use for TLS when verify_incoming is enabled. This can also be specified via the CONSUL_CLIENT_CERT environment variable.

  • -client-key=<value> - Path to a client key file to use for TLS when verify_incoming is enabled. This can also be specified via the CONSUL_CLIENT_KEY environment variable.

  • -http-addr=<addr> - Address of the Consul agent with the port. This can be an IP address or DNS address, but it must include the port. This can also be specified via the CONSUL_HTTP_ADDR environment variable. In Consul 0.8 and later, the default value is http://127.0.0.1:8500, and https can optionally be used instead. The scheme can also be set to HTTPS by setting the environment variable CONSUL_HTTP_SSL=true. This may be a unix domain socket using unix:///path/to/socket if the agent is configured to listen that way.

  • -tls-server-name=<value> - The server name to use as the SNI host when connecting via TLS. This can also be specified via the CONSUL_TLS_SERVER_NAME environment variable.

  • -token=<value> - ACL token to use in the request. This can also be specified via the CONSUL_HTTP_TOKEN environment variable. If unspecified, the query will default to the token of the Consul agent at the HTTP address.

  • -token-file=<value> - File containing the ACL token to use in the request instead of one specified via the -token argument or CONSUL_HTTP_TOKEN environment variable. This can also be specified via the CONSUL_HTTP_TOKEN_FILE environment variable.
