Consul Operator Autopilot

Command: consul operator autopilot

The Autopilot operator command is used to interact with Consul's Autopilot subsystem. The command can be used to view or modify the current Autopilot configuration. See the Autopilot Guide for more information about Autopilot.

Usage: consul operator autopilot <subcommand> [options]

The Autopilot operator command is used to interact with Consul's Autopilot
subsystem. The command can be used to view or modify the current configuration.

Subcommands:

    get-config    Display the current Autopilot configuration
    set-config    Modify the current Autopilot configuration

get-config

Corresponding HTTP API Endpoint: [GET] /v1/operator/autopilot/configuration

This command displays the current autopilot configuration.

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
operator:read

Usage: consul operator autopilot get-config [options]

Sample Output

$ consul operator autopilot get-config
CleanupDeadServers = true
LastContactThreshold = 200ms
MaxTrailingLogs = 250
ServerStabilizationTime = 10s
RedundancyZoneTag = ""
DisableUpgradeMigration = false
UpgradeMigrationTag = ""

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.

  • -datacenter=<name> - Name of the datacenter to query. If unspecified, the query will default to the datacenter of the Consul agent at the HTTP address.

  • -stale - Permit any Consul server (non-leader) to respond to this request. This allows for lower latency and higher throughput, but can result in stale data. This option has no effect on non-read operations. The default value is false.

set-config

Corresponding HTTP API Endpoint: [PUT] /v1/operator/autopilot/configuration

Modifies the current Autopilot configuration.

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
operator:write

Usage: consul operator autopilot set-config [options]

Sample Output

$ consul operator autopilot set-config -min-quorum=3
Configuration updated!

The return code indicates success or failure.

Command Options

  • -cleanup-dead-servers - Specifies whether to enable automatic removal of dead servers upon the successful joining of new servers to the cluster. Must be one of [true|false].

  • -last-contact-threshold - Controls the maximum amount of time a server can go without contact from the leader before being considered unhealthy. Must be a duration value such as 200ms.

  • -max-trailing-logs - Controls the maximum number of log entries that a server can trail the leader by before being considered unhealthy.

  • -min-quorum - Sets the minimum number of servers required in a cluster before autopilot is allowed to prune dead servers.

  • -server-stabilization-time - Controls the minimum amount of time a server must be stable in the 'healthy' state before being added to the cluster. Only takes effect if all servers are running Raft protocol version 3 or higher. Must be a duration value such as 10s.

  • -disable-upgrade-migration Enterprise - Controls whether Consul will avoid promoting new servers until it can perform a migration. Must be one of [true|false].

  • -redundancy-zone-tag Enterprise - Controls the -node-meta key name used for separating servers into different redundancy zones.

  • -upgrade-version-tag Enterprise - Controls the -node-meta tag to use for version info when performing upgrade migrations. If left blank, the Consul version will be used.
