api ACL Tokens - HTTP API api-acl-tokens The /acl/token endpoints manage Consul's ACL Tokens.

-> 1.4.0+: The APIs are available in Consul versions 1.4.0 and later. The documentation for the legacy ACL API is here

ACL Token HTTP API

The /acl/token endpoints create, read, update, list, clone and delete ACL policies in Consul.

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

Create a Token

This endpoint creates a new ACL token.

Method Path Produces
PUT /acl/token 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

  • AccessorID (string: "") - Specifies a UUID to use as the token's Accessor ID. If not specified a UUID will be generated for this field. Added in v1.5.0.

  • SecretID (string: "") - Specifies a UUID to use as the token's Secret ID. If not specified a UUID will be generated for this field. Added in v1.5.0. Note: The SecretID is used to authorize operations against Consul and should be generated from an appropriate cryptographic source.

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

  • Policies (array<PolicyLink>) - The list of policies that should be applied to the token. A PolicyLink is an object with an "ID" and/or "Name" field to specify a policy. With the PolicyLink, tokens 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 tokens internally by IDs, Consul enables policy renaming without breaking tokens.

  • Roles (array<RoleLink>) - The list of roles that should be applied to the token. A RoleLink is an object with an "ID" and/or "Name" field to specify a role. With the RoleLink, tokens can be linked to roles either by the role name or by the role ID. When roles are linked by name they will be internally resolved to the role ID. With linking tokens internally by IDs, Consul enables role renaming without breaking tokens. Added in Consul 1.5.0.

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

  • Local (bool: false) - If true, indicates that the token should not be replicated globally and instead be local to the current datacenter.

  • 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. This value must be between 1 minute and 24 hours in the future. Added in Consul 1.5.0.

  • ExpirationTTL (duration: 0s) - This is a convenience field and if set will initialize the ExpirationTime field to a value of CreateTime + ExpirationTTL. This field is not persisted beyond its initial use. Can be specified in the form of "60s" or "5m" (i.e., 60 seconds or 5 minutes, respectively). This value must be no smaller than 1 minute and no longer than 24 hours. Added in Consul 1.5.0.

Read a Token

This endpoint reads an ACL token with the given Accessor ID.

Method Path Produces
GET /acl/token/:AccessorID 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
YES all none acl:read

Parameters

  • AccessorID (string: <required>) - Specifies the accessor ID of the ACL token to read. This is required and is specified as part of the URL path.

Sample Request

$ curl -X GET http://127.0.0.1:8500/v1/acl/token/6a1253d2-1785-24fd-91c2-f8e78c745511

Sample Response

-> Note If the token used for accessing the API has acl:write permissions, then the SecretID will contain the tokens real value. Only when accessed with a token with only acl:read permissions will the SecretID be redacted. This is to prevent privilege escalation whereby having acl:read privileges allows for reading other secrets which given even more permissions.

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

Parameters

  • AccessorID (string: "") - Specifies the accessor ID of the token being updated. This is required in the URL path but may also be specified in the JSON body. If specified in both places then they must match exactly. This field is immutable. If not present in the body and only in the URL then it will be filled in by Consul.

  • SecretID (string: "") - Specifies the secret ID of the token being updated. This field is immutable so if present in the body then it must match the existing value. If not present then the value will be filled in by Consul.

  • Description (string: "") - Free form human readable description of this token.

  • Policies (array<PolicyLink>) - This is the list of policies that should be applied to this token. A PolicyLink is an object with an "ID" and/or "Name" field to specify a policy.

With the RoleLink, tokens can be linked to roles either by the role name or by the role ID. When roles are linked by name they will be internally resolved to the role ID. With linking tokens internally by IDs, Consul enables role renaming without breaking tokens.

  • Local (bool: false) - If true, indicates that this token should not be replicated globally and instead be local to the current datacenter. This value must match the existing value or the request will return an error.

  • AuthMethod (string: "") - Specifies the name of the auth method that created this token. This field is immutable so if present in the body then it must match the existing value. If not present then the value will be filled in by Consul.

  • ExpirationTime (time: "") - Specifies the expiration time for the token being updated. This field is immutable so if present in the body then it must match the existing value. If not present then the value will be filled in by Consul.
