ACL Tokens HTTP API

The /acl/bootstrap, /acl/tokens, and /acl/token/ endpoints are used to manage ACL tokens. For more details about ACLs, please see the ACL Guide.

Bootstrap Token

This endpoint is used to bootstrap the ACL system and provide the initial management token. An operator created token can be provided in the body of the request to bootstrap the cluster if required. If no header is provided the cluster will return a generated management token. The provided token should be presented in a UUID format. This request is always forwarded to the authoritative region. It can only be invoked once until a bootstrap reset is performed.

List Tokens

This endpoint lists all ACL tokens. This lists the local tokens and the global tokens which have been replicated to the region, and may lag behind the authoritative region.

Method	Path	Produces
`GET`	`/acl/tokens`	`application/json`

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

Blocking Queries	Consistency Modes	ACL Required
`YES`	`all`	`management`

Parameters

global (bool: false) - If true, only return ACL tokens that are replicated globally to all regions.
prefix (string: "") - Specifies a string to filter ACL tokens based on an accessor ID prefix. Because the value is decoded to bytes, the prefix must have an even number of hexadecimal characters (0-9a-f). This is specified as a query string parameter.
next_token (string: "") - This endpoint supports paging. The next_token parameter accepts a string which identifies the next expected ACL token. This value can be obtained from the X-Nomad-NextToken header from the previous response.
per_page (int: 0) - Specifies a maximum number of ACL tokens to return for this request. If omitted, the response is not paginated. The value of the X-Nomad-NextToken header of the last response can be used as the next_token of the next request to fetch additional pages.
filter (string: "") - Specifies the expression used to filter the results. Consider using pagination or a query parameter to reduce resource used to serve the request.
reverse (bool: false) - Specifies the list of returned ACL tokens should be sorted in the reverse order. By default ACL tokens are returned sorted in chronological order (older ACL tokens first), or in lexicographical order by their ID if the prefix or global query parameters are used.

Create Token

This endpoint creates an ACL Token. If the token is a global token, the request is forwarded to the authoritative region.

Method	Path	Produces
`POST`	`/acl/token`	`application/json`

The table below shows this endpoint's support for blocking queries and required ACLs.

Blocking Queries	ACL Required
`NO`	`management`

Parameters

Name (string: <optional>) - Specifies the human-readable name of the token.
Type (string: <required>) - Specifies the type of token. Must be either client or management.
Policies (array<string>: <required>) - Must be null or blank for management type tokens, otherwise must specify at least one policy for client type tokens.
Global (bool: <optional>) - If true, indicates this token should be replicated globally to all regions. Otherwise, this token is created local to the target region.
ExpirationTime (time: "") - If set, this represents the point after which a token should be considered revoked and is eligible for destruction. The default unset value represents NO expiration.
ExpirationTTL (duration: 0s) - This is a convenience field and if set will initialize the ExpirationTime field to a value of CreateTime + ExpirationTTL. This value must be between the token_min_expiration_ttl and token_max_expiration_ttl ACL configuration parameters.
