ACL Roles - HTTP API
The /acl/role endpoints manage Consul's ACL Roles.

ACL Role HTTP API

-> 1.5.0+: The role APIs are available in Consul versions 1.5.0 and newer.

The /acl/role endpoints create, read, update, list and delete ACL roles in Consul.

For more information on how to setup ACLs, refer to the following resources:

Create a Role

This endpoint creates a new ACL role.

Method Path Produces
PUT /acl/role 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

The corresponding CLI command is consul acl role create.

Query Parameters

JSON Request Body Schema

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

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

  • Policies (array<PolicyLink>) - The list of policies that should be applied to the role. A PolicyLink is an object with an "ID" and/or "Name" field to specify a policy. With the PolicyLink, roles can be linked to policies either by the policy name or by the policy ID. When policies are linked by name they will be internally resolved to the policy ID. With linking roles internally by IDs, Consul enables policy renaming without breaking tokens.

  • TemplatedPolicies (list of maps) - The list of templated policies that should be applied to the role.

    • TemplateName (string: <required>) - The templated policy name.

    • TemplateVariables (map of strings|maps: <optional>) - The templated policy variables. Not all templated policies require variables.

  • ServiceIdentities (array<ServiceIdentity>) - The list of service identities that should be applied to the role.

    • ServiceName (string: <required>) - The name of the service. The name must be no longer than 256 characters, must start and end with a lowercase alphanumeric character, and can only contain lowercase alphanumeric characters as well as - and _.

    • Datacenters (array<string>) - Specifies the datacenters the effective policy is valid within. When no datacenters are provided the effective policy is valid in all datacenters including those which do not yet exist but may in the future.

  • NodeIdentities (array<NodeIdentity>) - The list of node identities that should be applied to the role.

    • NodeName (string: <required>) - The name of the node. The name must be no longer than 256 characters, must start and end with a lowercase alphanumeric character, and can only contain lowercase alphanumeric characters as well as - and _.

    • Datacenter (string: <required>) - Specifies the nodes datacenter. This will result in effective policy only being valid in that datacenter.

  • Namespace (string: "") - Specifies the namespace of the role you create. This field takes precedence over the ns query parameter, one of several other methods to specify the namespace.

Methods to specify namespace

ACL role endpoints support several methods for specifying the namespace of the ACL role resources with the following order of precedence:

  1. Namespace field of the JSON request body - only applies to create and update endpoints
  2. ns query parameter
  3. X-Consul-Namespace request header
  4. Namespace is inherited from the namespace of the request's ACL token (if any)
  5. The default namespace
