Most users will not need to interact with these commands. Here are a few examples of the Raft operator commands: Subcommands: join Joins a node to the Raft cluster list-peers Returns the Raft peer set remove-peer Removes a node from the Raft cluster snapshot Restores and saves snapshots from the Raft cluster ``` ## join This command is used to join a new node as a peer to the Raft cluster. In order to join, there must be at least one existing member of the cluster. If Shamir seal is in use, then unseal keys are to be supplied before or after the join process, depending on whether it's being used exclusively for HA. If raft is used for `storage`, the node must be joined before unsealing and the `leader-api-addr` argument must be provided. If raft is used for `ha_storage`, the node must be first unsealed before joining and the `leader-api-addr` must _not_ be provided. ```text Usage: vault operator raft join [options] Join the current node as a peer to the Raft cluster by providing the address of the Raft leader node. $ vault operator raft join "http://127.0.0.2:8200" ``` The `join` command also allows operators to specify cloud auto-join configuration instead of a static IP address or hostname. When provided, Vault will attempt to automatically discover and resolve potential leader addresses based on the provided auto-join configuration. Vault uses go-discover to support the auto-join functionality. Please see the go-discover [README](https://github.com/hashicorp/go-discover/blob/master/README.md) for details on the format. By default, Vault will attempt to reach discovered peers using HTTPS and port 8200. Operators may override these through the `--auto-join-scheme` and `--auto-join-port` CLI flags respectively. ```text Usage: vault operator raft join [options] Join the current node as a peer to the Raft cluster by providing cloud auto-join metadata configuration. $ vault operator raft join "provider=aws region=eu-west-1 ..." ``` ### Parameters The following flags are available for the `operator raft join` command. - `-leader-ca-cert` `(string: "")` - CA cert to communicate with Raft leader. - `-leader-client-cert` `(string: "")` - Client cert to authenticate to Raft leader. - `-leader-client-key` `(string: "")` - Client key to authenticate to Raft leader. - `-non-voter` `(bool: false) (enterprise)` - This flag is used to make the server not participate in the Raft quorum, and have it only receive the data replication stream. This can be used to add read scalability to a cluster in cases where a high volume of reads to servers are needed. The default is false. See [`retry_join_as_non_voter`](/docs/configuration/storage/raft#retry_join_as_non_voter) for the equivalent config option when using `retry_join` stanzas instead. - `-retry` `(bool: false)` - Continuously retry joining the Raft cluster upon failures. The default is false. ~> **Note:** Please be aware that the content (not the path to the file) of the certificate or key is expected for these parameters: `-leader-ca-cert`, `-leader-client-cert`, `-leader-client-key`. ## list-peers This command is used to list the full set of peers in the Raft cluster. ```text Usage: vault operator raft list-peers Provides the details of all the peers in the Raft cluster. $ vault operator raft list-peers ``` ### Example Output ```json { ... "data": { "config": { "index": 62, "servers": [ { "address": "127.0.0.2:8201", "leader": true, "node_id": "node1", "protocol_version": "3", "voter": true }, { "address": "127.0.0.4:8201", "leader": false, "node_id": "node3", "protocol_version": "3", "voter": true } ] } } } ``` ## remove-peer This command is used to remove a node from being a peer to the Raft cluster. In certain cases where a peer may be left behind in the Raft configuration even though the server is no longer present and known to the cluster, this command can be used to remove the failed server so that it is no longer affects the Raft quorum. ```text Usage: vault operator raft remove-peer Removes a node from the Raft cluster. $ vault operator raft remove-peer node1 ``` ## snapshot This command groups subcommands for operators interacting with the snapshot functionality of the integrated Raft storage backend. There are 2 subcommands supported: `save` and `restore`. ```text Usage: vault operator raft snapshot [options] [args] This command groups subcommands for operators interacting with the snapshot functionality of the integrated Raft storage backend. Subcommands: restore Installs the provided snapshot, returning the cluster to the state defined in it save Saves a snapshot of the current state of the Raft cluster into a file ``` ### snapshot save Takes a snapshot of the Vault data. The snapshot can be used to restore Vault to the point in time when a snapshot was taken. ```text Usage: vault operator raft snapshot save Saves a snapshot of the current state of the Raft cluster into a file. $ vault operator raft snapshot save raft.snap ``` ~> **Note:** Snapshot is not supported when Raft is used only for `ha_storage`. ### snapshot restore Restores a snapshot of Vault data taken with `vault operator raft snapshot save`. ```text Usage: vault operator raft snapshot restore Installs the provided snapshot, returning the cluster to the state defined in it. $ vault operator raft snapshot restore raft.snap ``` ## autopilot This command groups subcommands for operators interacting with the autopilot functionality of the integrated Raft storage backend. There are 3 subcommands supported: `get-config`, `set-config` and `state`. For a more detailed overview of autopilot features, see the [concepts page](/docs/concepts/integrated-storage/autopilot). ```text Usage: vault operator raft autopilot [options] [args] This command groups subcommands for operators interacting with the autopilot functionality of the integrated Raft storage backend. Subcommands: get-config Returns the configuration of the autopilot subsystem under integrated storage set-config Modify the configuration of the autopilot subsystem under integrated storage state Displays the state of the raft cluster under integrated storage as seen by autopilot ``` ### autopilot state Displays the state of the raft cluster under integrated storage as seen by autopilot. It shows whether autopilot thinks the cluster is healthy or not, and how many nodes could fail before the cluster becomes unhealthy ("Failure Tolerance"). State includes a list of all servers by nodeID and IP address. Last Index indicates how close the state on each node is to the leader's. A node can have a status of "leader", "voter", and "[non-voter](/docs/concepts/integrated-storage#non-voting-nodes-enterprise-only)". ```text Usage: vault operator raft autopilot state Displays the state of the raft cluster under integrated storage as seen by autopilot. $ vault operator raft autopilot state ``` #### Example Output ```text Healthy: true Failure Tolerance: 1 Leader: raft1 Voters: raft1 raft2 raft3 Servers: raft1 Name: raft1 Address: 127.0.0.1:8201 Status: leader Node Status: alive Healthy: true Last Contact: 0s Last Term: 3 Last Index: 38 raft2 Name: raft2 Address: 127.0.0.2:8201 Status: voter Node Status: alive Healthy: true Last Contact: 2.514176729s Last Term: 3 Last Index: 38 ``` Vault Enterprise will include additional output related to automated upgrades and redundancy zones. #### Example Vault Enterprise Output ```text Redundancy Zones: a Servers: vault_1, vault_2, vault_5 Voters: vault_1 Failure Tolerance: 2 b Servers: vault_3, vault_4 Voters: vault_3 Failure Tolerance: 1 Upgrade Info: Status: await-new-voters Target Version: 1.12.0 Target Version Voters: Target Version Non-Voters: vault_5 Other Version Voters: vault_1, vault_3 Other Version Non-Voters: vault_2, vault_4 Redundancy Zones: a Target Version Voters: Target Version Non-Voters: vault_5 Other Version Voters: vault_1 Other Version Non-Voters: vault_2 b Target Version Voters: Target Version Non-Voters: Other Version Voters: vault_3 Other Version Non-Voters: vault_4 ``` ### autopilot get-config Returns the configuration of the autopilot subsystem under integrated storage. ```text Usage: vault operator raft autopilot get-config Returns the configuration of the autopilot subsystem under integrated storage. $ vault operator raft autopilot get-config ``` ### autopilot set-config Modify the configuration of the autopilot subsystem under integrated storage. ```text Usage: vault operator raft autopilot set-config [options] Modify the configuration of the autopilot subsystem under integrated storage. $ vault operator raft autopilot set-config -server-stabilization-time 10s ``` Flags applicable to this command are the following: - `cleanup-dead-servers` `(bool)` - Controls whether to remove dead servers from the Raft peer list periodically or when a new server joins. This requires that `min-quorum` is also set. Defaults to `false`. - `last-contact-threshold` `(string)` - Limit on the amount of time a server can go without leader contact before being considered unhealthy. Defaults to `10s`. - `dead-server-last-contact-threshold` `(string)` - Limit on the amount of time a server can go without leader contact before being considered failed. This takes effect only when `cleanup_dead_servers` is set as `true`. Defaults to `24h`. -> **Note:** A failed server that autopilot has removed from the raft configuration cannot rejoin the cluster without being reinitialized. - `max-trailing-logs` `(int)` - Amount of entries in the Raft Log that a server can be behind before being considered unhealthy. Defaults to `1000`. - `min-quorum` `(int)` - Minimum number of servers that should always be present in a cluster. Autopilot will not prune servers below this number. This should be set to the expected number of voters in your cluster. There is no default. - `server-stabilization-time` `(string)` - Minimum amount of time a server must be in a healthy state before it can become a voter. Until that happens, it will be visible as a peer in the cluster, but as a non-voter, meaning it won't contribute to quorum. Defaults to `10s`. - `disable-upgrade-migration` `(bool)` - Controls whether to disable automated upgrade migrations, an Enterprise-only feature. Defaults to `false`.
