Consul
Keyring Operator HTTP API
The /operator/keyring
endpoints allow for management of the gossip encryption
keyring. Please see the Gossip Protocol Guide for
more details on the gossip protocol and its use.
List Gossip Encryption Keys
This endpoint lists the gossip encryption keys installed on both the WAN and LAN
rings of every known datacenter, unless otherwise specified with the local-only
query parameter (see below).
If ACLs are enabled, the client will need to supply an ACL Token with keyring
read privileges.
Method | Path | Produces |
---|---|---|
GET | /operator/keyring | 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 | keyring:read |
The corresponding CLI command is consul keyring -list
.
Query Parameters
relay-factor
(int: 0)
- Specifies the relay factor. Setting this to a non-zero value will cause nodes to relay their responses through this many randomly-chosen other nodes in the cluster. The maximum allowed value is5
.local-only
(bool: false)
- Settinglocal-only
to true will force keyring list queries to only hit local servers (no WAN traffic). This flag can only be set for list queries.

WAN
is true if the block refers to the WAN ring of that datacenter (rather than LAN).Datacenter
is the datacenter the block refers to.Segment
is the network segment the block refers to.Keys
is a map of each gossip key to the number of nodes it's currently installed on.PrimaryKeys
is a map of each primary gossip key to the number of nodes it's currently installed on.NumNodes
is the total number of nodes in the datacenter.
Add New Gossip Encryption Key
This endpoint installs a new gossip encryption key into the cluster.

.
Query Parameters
relay-factor
(int: 0)
- Specifies the relay factor. Setting this to a non-zero value will cause nodes to relay their responses through this many randomly-chosen other nodes in the cluster. The maximum allowed value is5
.
JSON Request Body Schema
Key
(string: <required>)
- Specifies the encryption key to begin using as primary into the cluster.
