Consul ACL Auth Method Update

Command: consul acl auth-method update

Corresponding HTTP API Endpoint: [PUT] /v1/acl/auth-method/:name

The acl auth-method update command is used to update an auth method. The default operations is to merge the current auth method with those values provided to the command invocation. Therefore to update just one field, only the -name options and the option to modify must be provided.

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
acl:write

Usage

Usage: consul acl auth-method update [options] [args]

Command Options

  • -description=<string> - A description of the auth method.

  • -display-name=<string> - An optional name to use instead of the name when displaying this auth method in a UI. Added in Consul 1.8.0.

  • -max-token-ttl=<duration> - Duration of time all tokens created by this auth method should be valid for. Added in Consul 1.8.0.

  • -token-locality=<string> - Defines the kind of token that this auth method should produce. This can be either 'local' or 'global'. If empty the value of 'local' is assumed. Added in Consul 1.8.0.

  • -config=<string> - The configuration for the auth method. Must be JSON. May be prefixed with '@' to indicate that the value is a file path to load the config from. '-' may also be given to indicate that the config is available on stdin. Added in Consul 1.8.0.

  • -kubernetes-ca-cert=<string> - PEM encoded CA cert for use by the TLS client used to talk with the Kubernetes API. May be prefixed with '@' to indicate that the value is a file path to load the cert from. This flag is required for -type=kubernetes.

  • -kubernetes-host=<string> - Address of the Kubernetes API server. This flag is required for -type=kubernetes.

  • -kubernetes-service-account-jwt=<string> - A Kubernetes service account JWT used to access the TokenReview API to validate other JWTs during login. This flag is required for -type=kubernetes.

  • -meta - Indicates that auth method metadata such as the raft indices should be shown for each entry

  • -name=<string> - The name of the auth method to update.

  • -no-merge - Do not merge the current auth method information with what is provided to the command. Instead overwrite all fields with the exception of the auth method ID which is immutable.

  • -format={pretty|json} - Command output format. The default value is pretty.

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.
  • -namespace=<string> - Specifies the namespace to query. If not provided, the namespace will be inferred from the request's ACL token, or will default to the default namespace. Namespaces are a Consul Enterprise feature added in v1.7.0.

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.

  • -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.
