# 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 see the [Autopilot Guide](https://learn.hashicorp.com/consul/day-2-operations/autopilot) 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).
|
|
|
|
| Blocking Queries | Consistency Modes | Agent Caching | ACL Required |
|
|
| ---------------- | ----------------- | ------------- | --------------- |

|
| `NO` | `none` | `none` | `operator:read` |
|
|
|
|
### 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.
|
|
|
|

|
- `Healthy` is whether all the servers are currently healthy.
|
|
|
|
- `FailureTolerance` is the number of redundant healthy servers that could be
|
|
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.
|
|
|
|
- `SerfStatus` is the SerfHealth check status for the server.
|
|
|
|
- `Version` is the Consul version of the server.
|
|
|
|
- `Leader` is whether this server is currently the leader.
|
|
|
|
- `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.
|
|
|
|
- `Voter` is whether the server is a voting member of the Raft cluster.
|
|
|
|
- `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.
