api	Legacy ACLs - HTTP API	api-acls-legacy	The /acl endpoints create, update, destroy, and query Legacy ACL tokens in Consul.

-> Consul 1.4.0 deprecates the legacy ACL system completely. It's strongly recommended you do not build anything using the legacy system and consider using the new ACL Token and Policy APIs instead.

ACL HTTP API

These /acl endpoints create, update, destroy, and query ACL tokens in Consul. For more information about ACLs, please see the ACL Guide.

Bootstrap ACLs

This endpoint does a special one-time bootstrap of the ACL system, making the first management token if the acl_master_token is not specified in the Consul server configuration, and if the cluster has not been bootstrapped previously. This is available in Consul 0.9.1 and later, and requires all Consul servers to be upgraded in order to operate.

This provides a mechanism to bootstrap ACLs without having any secrets present in Consul's configuration files.

Method	Path	Produces
`PUT`	`/acl/bootstrap`	`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`	`none`

Sample Request

$ curl \
    --request PUT \
    http://127.0.0.1:8500/v1/acl/bootstrap

Sample Response

{
  "ID": "adf4238a-882b-9ddc-4a9d-5b6758e4159e"
}

You can detect if something has interfered with the ACL bootstrapping process by checking the response code. A 200 response means that the bootstrap was a success, and a 403 means that the cluster has already been bootstrapped, at which point you should consider the cluster in a potentially compromised state.

The returned token will be a management token which can be used to further configure the ACL system. Please see the ACL Guide for more details.

Create ACL Token

This endpoint makes a new ACL token.

Method	Path	Produces
`PUT`	`/acl/create`	`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`	`management`

Parameters

ID (string: "") - Specifies the ID of the ACL. If not provided, a UUID is generated.
Name (string: "") - Specifies a human-friendly name for the ACL token.
Type (string: "client") - Specifies the type of ACL token. Valid values are: client and management.
Rules (string: "") - Specifies rules for this ACL token. The format of the Rules property is documented in the ACL Guide.

`GET`	`/acl/info/:uuid`	`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`	`none`

Note: No ACL is required because the ACL is specified in the URL path.

Parameters

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

Sample Request

$ curl \
    http://127.0.0.1:8500/v1/acl/info/8f246b77-f3e1-ff88-5b48-8ec93abf3e05

Check ACL Replication

This endpoint returns the status of the ACL replication process in the datacenter. This is intended to be used by operators, or by automation checking the health of ACL replication.

Please see the ACL Replication Guide for more details. for more details.

Method	Path	Produces
`GET`	`/acl/replication`	`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`	`consistent`	`none`	`none`

Parameters

dc (string: "") - Specifies the datacenter to query. This will default to the datacenter of the agent being queried. This is specified as part of the URL as a query parameter.

Sample Request

$ curl \
    http://127.0.0.1:8500/v1/acl/replication

Sample Response

{
  "Enabled": true,
  "Running": true,
  "SourceDatacenter": "dc1",
  "ReplicatedIndex": 1976,
  "LastSuccess": "2016-08-05T06:28:58Z",
  "LastError": "2016-08-05T06:28:28Z"
}

Enabled reports whether ACL replication is enabled for the datacenter.
Running reports whether the ACL replication process is running. The process may take approximately 60 seconds to begin running after a leader election occurs.
SourceDatacenter is the authoritative ACL datacenter that ACLs are being replicated from, and will match the primary_datacenter configuration.
ReplicatedIndex is the last index that was successfully replicated. You can compare this to the X-Consul-Index header returned by the /v1/acl/list endpoint to determine if the replication process has gotten all available ACLs. Replication runs as a background process approximately every 30 seconds, and that local updates are rate limited to 100 updates/second, so so it may take several minutes to perform the initial sync of a large set of ACLs. After the initial sync, replica lag should be on the order of about 30 seconds.
LastSuccess is the UTC time of the last successful sync operation. Since ACL replication is done with a blocking query, this may not update for up to 5 minutes if there have been no ACL changes to replicate. A zero value of "0001-01-01T00:00:00Z" will be present if no sync has been successful.
LastError is the UTC time of the last error encountered during a sync operation. If this time is later than LastSuccess, you can assume the replication process is not in a good state. A zero value of "0001-01-01T00:00:00Z" will be present if no sync has resulted in an error.
