Method Path Produces
PUT /acl/auth-method application/json

The table below shows this endpoint's support for blocking queries, consistency modes, agent caching, and required ACLs.

Blocking Queries Consistency Modes Agent Caching ACL Required
NO none none acl:write

Payload Fields

  • Name (string: <required>) - Specifies a name for the ACL auth method. The name can contain alphanumeric characters, dashes -, and underscores _. This field is immutable and must be unique.

  • Type (string: <required>) - The type of auth method being configured. The only allowed value in Consul 1.5.0 is "kubernetes". This field is immutable.

  • Description (string: "") - Free form human readable description of the auth method.

  • Config (map[string]string: <required>) - The raw configuration to use for the chosen auth method. Contents will vary depending upon the type chosen. For more information on configuring specific auth method types, see the auth method documentation.

  • Namespace (string: "") - (Enterprise Only) Specifies the namespace to create the auth method within. If not provided in the JSON body, the value of the ns URL query parameter or in the X-Consul-Namespace header will be used. If not provided at all, the namespace will default to the default namespace. Added in Consul 1.7.0.
