# Autopilot Operator HTTP API
|
|
|
|
The `/operator/autopilot` endpoints allow for automatic operator-friendly
|
|
management of Consul servers including cleanup of dead servers, monitoring
|
|
the state of the Raft cluster, and stable server introduction.
|
|
|
|
Please check the [Autopilot tutorial](https://learn.hashicorp.com/tutorials/consul/autopilot-datacenter-operations) for more details.
|
|
|
|
## Read Configuration
|
|
|
|
This endpoint retrieves its latest Autopilot configuration.
|
|
|
|
| Method | Path | Produces |
|
|
| ------ | ----------------------------------- | ------------------ |
|
|
| `GET` | `/operator/autopilot/configuration` | `application/json` |
|
|
|
|
The table below shows this endpoint's support for
|
|
[blocking queries](/api/features/blocking),
|
|
[consistency modes](/api/features/consistency),
|
|
[agent caching](/api/features/caching), and
|
|
[required ACLs](/api#authentication).
|

### 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 string.
|
|
|
|
- `stale` `(bool: false)` - If the cluster does not currently have a leader an
|
|
error will be returned. You can use the `?stale` query parameter to read the
|
|
Raft configuration from any of the Consul servers.
|
|

### 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 string.
|
|
|
|
- `cas` `(int: 0)` - Specifies to use a Check-And-Set operation. The update will
|
|
only happen if the given index matches the `ModifyIndex` of the configuration
|
|
at the time of writing.
|
|
|
|
- `CleanupDeadServers` `(bool: true)` - Specifies automatic removal of dead
|
|
server nodes periodically and whenever a new server is added to the cluster.
|
|
|
|
- `LastContactThreshold` `(string: "200ms")` - Specifies the maximum amount of
|
|
time a server can go without contact from the leader before being considered
|
|
unhealthy. Must be a duration value such as `10s`.
|
|
|
|
- `MaxTrailingLogs` `(int: 250)` specifies the maximum number of log entries
|
|
that a server can trail the leader by before being considered unhealthy.
|
|
|
|
- `MinQuorum` `(int: 0)` - specifies the minimum number of servers needed before
|
|
Autopilot can prune dead servers.
|
|
|
|
- `ServerStabilizationTime` `(string: "10s")` - Specifies the minimum amount of
|
|
time a server must be stable in the 'healthy' state before being added to the
|
|
cluster. Only takes effect if all servers are running Raft protocol version 3
|
|
or higher. Must be a duration value such as `30s`.
|
|
|
|
- `RedundancyZoneTag` `(string: "")` - Controls the node-meta key to use when
|
|
Autopilot is separating servers into zones for redundancy. Only one server in
|
|
each zone can be a voting member at one time. If left blank, this feature will
|
|
be disabled.
|
|
|
|
- `DisableUpgradeMigration` `(bool: false)` - Disables Autopilot's upgrade
|
|
migration strategy in Consul Enterprise of waiting until enough
|
|
newer-versioned servers have been added to the cluster before promoting any of
|
|
them to voters.
|
|
|
|
- `UpgradeVersionTag` `(string: "")` - Controls the node-meta key to use for
|
|
version info when performing upgrade migrations. If left blank, the Consul
|
|
version will be used.
|
|
|
|

|
|
fail without causing an outage (this would be 2 in a healthy cluster of 5
|
|
servers).
|
|
|
|
- `Servers` holds detailed health information on each server:
|
|
|
|
- `ID` is the Raft ID of the server.
|
|
|
|
- `Name` is the node name of the server.
|
|
|
|
- `Address` is the address of the server.
|
|

|
|
|
|
- `Leader` is whether this server is currently the leader.
|

- `Healthy` is whether the server is healthy according to the current Autopilot configuration.
|
|
|
|

|
|
|
|
- `StableSince` is the time this server has been in its current `Healthy` state.
|
|
|
|
The HTTP status code will indicate the health of the cluster. If `Healthy` is true, then a
|
|
status of 200 will be returned. If `Healthy` is false, then a status of 429 will be returned.

|
|
"Name": "node1",
|
|
"Address": "198.18.0.1:8300",

|
|
"zone": "az1"
|
|
},
|
|
"NodeType": "redundancy-zone-voter"
|
|
}
|
|
```
|
|
|
|
- `ID` is the Raft ID of the server.
|
|
|
|
- `Name` is the node name of the server.
|
|
|
|
- `Address` is the address of the server.
|
|
|
|
- `NodeStatus` is the SerfHealth check status for the server.
|
|
|
|
- `Version` is the Consul version of the server.
|
|
|
|
- `LastContact` is the time elapsed since this server's last contact with the leader.
|
|
|
|
- `LastTerm` is the server's last known Raft leader term.
|
|
|
|
- `LastIndex` is the index of the server's last committed Raft log entry.
|
|
|
|
- `Healthy` is whether the server is healthy according to the current Autopilot configuration.
|
|
|
|
- `StableSince` is the time this server has been in its current `Healthy` state.
|
|
- `RedundancyZone` <EnterpriseAlert inline /> is the name of the redundancy zone this server is within.
|
|
- `UpgradeVersion` <EnterpriseAlert inline /> is the version that will be used for automated upgrade calculations.
|
|
- `ReadReplica` <EnterpriseAlert inline /> indicates whether this server is a read replica or not.
|
|
- `Status` indicates the current Raft status of this server. Possible values are:
|
|
`leader`, `voter`, `non-voter`, or `staging`.
|
|
- `Meta` is the node metadata of this server. Values within this map are used for determining a server's
|
|
redundancy zone and upgrade version.
|
|
- `NodeType` is the desired type autopilot thinks this server should have. In Consul OSS the only possible
|
|
value is `voter` as all present servers should having voting rights. In Consul Enterprise the possible values also
|
|
include `read-replica`, `zone-voter`, `zone-standby` and `zone-extra-voter`. `zone-voter` indicates that autopilot
|
|
wants this server to be the voter for a particular redundancy zone. When a zone has no voter all nodes will be typed
|
|
as this until one is promoted. When that happens the other non-voters in the zone will be typed as `zone-standby`.
|
|
This indicates that they are currently desired to be standby servers in case the voter from the zone fails. Finally,
|
|
the `zone-extra-voter` status indicates that autopilot wants this server to be a voter due to a failure of all servers
|
|
in another zone and that when one of the servers in that failed zone are restored, this server will be demoted.
|
|
|
|
### Redundancy Zone Response Format <EnterpriseAlert inline />

|
|
}
|
|
```
|
|
|
|
Each zone in the responses `RedundancyZones` mapping will have this structure.
|
|
|
|
- `Servers` is a list of server IDs of all the servers in this zone. These values can be used as indexes
|
|
into the top level response's `Servers` mapping.
|
|
- `Voters` is a list of server IDs of all servers in this zone that have voting rights. Typically this will
|
|
be a list with 1 value but in some failure scenarios or upgrade scenarios the size could increase. These
|
|
values can be used as indexes into the top level response's `Servers` mapping.
|
|
|
|
- `FailureTolerance` is the number of servers in this zone that could fail without causing a total zone failure
|
|
and subsequent promotion of a server from another zone as a fallback.
