See the [Outage Recovery](/guides/outage.html) guide for some examples of how these capabilities are used. For a CLI to perform these operations manually, please see the documentation for the [`nomad operator`](/docs/commands/operator-index.html) command. ## Read Raft Configuration This endpoint queries the status of a client node registered with Nomad. | Method | Path | Produces | | ------ | --------------------------------- | -------------------------- | | `GET` | `/v1/operator/raft/configuration` | `application/json` | The table below shows this endpoint's support for [blocking queries](/api/index.html#blocking-queries), [consistency modes](/api/index.html#consistency-modes), and [required ACLs](/api/index.html#acls). | Blocking Queries | Consistency Modes | ACL Required | | ---------------- | ----------------- | ------------ | | `NO` | `all` | `none` | ### Parameters - `stale` - Specifies if the cluster should respond without an active leader. This is specified as a querystring parameter. ### Sample Request ```text $ curl \ https://nomad.rocks/v1/operator/raft/configuration ``` ### Sample Response ```json { "Index": 1, "Servers": [ { "Address": "127.0.0.1:4647", "ID": "127.0.0.1:4647", "Leader": true, "Node": "bacon-mac.global", "Voter": true } ] } ``` #### Field Reference - `Index` `(int)` - The `Index` value is the Raft corresponding to this configuration. The latest configuration may not yet be committed if changes are in flight. - `Servers` `(array: Server)` - The returned `Servers` array has information about the servers in the Raft peer configuration. - `ID` `(string)` - The ID of the server. This is the same as the `Address` but may be upgraded to a GUID in a future version of Nomad. - `Node` `(string)` - The node name of the server, as known to Nomad, or `"(unknown)"` if the node is stale and not known. - `Address` `(string)` - The `ip:port` for the server. - `Leader` `(bool)` - is either "true" or "false" depending on the server's role in the Raft configuration. - `Voter` `(bool)` - is "true" or "false", indicating if the server has a vote in the Raft configuration. Future versions of Nomad may add support for non-voting servers. ## Remove Raft Peer This endpoint removes a Nomad server with given address from the Raft configuration. The return code signifies success or failure. | Method | Path | Produces | | -------- | ---------------------------| -------------------------- | | `DELETE` | `/v1/operator/raft/peer` | `application/json` | The table below shows this endpoint's support for [blocking queries](/api/index.html#blocking-queries), [consistency modes](/api/index.html#consistency-modes), and [required ACLs](/api/index.html#acls). | Blocking Queries | Consistency Modes | ACL Required | | ---------------- | ----------------- | ------------ | | `NO` | `all` | `none` | ### Parameters - `address` `(string: )` - Specifies the server to remove as `ip:port`. This may be provided multiple times and is provided as a querystring parameter. - `stale` - Specifies if the cluster should respond without an active leader. This is specified as a querystring parameter. ### Sample Request ```text $ curl \ --request DELETE \ https://nomad.rocks/v1/operator/raft/peer?address=1.2.3.4 ```
