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, please check the ACL tutorial.

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.

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.
NodeIdentities (array<NodeIdentity>) - The list of node identities that should be applied to the role. Added in Consul 1.8.1.
- 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: "") Enterprise - Specifies the namespace to create the role. 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, the namespace will be inherited from the request's ACL token or will default to the default namespace. Added in Consul 1.7.0.
