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

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

ACL Role HTTP API

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

For more information on how to setup ACLs, please see the ACL Guide.

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

Parameters

  • 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.

  • ServiceIdentities (array<ServiceIdentity>) - The list of service identities that should be applied to the role. Added in Consul 1.5.0.

    • 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.
