# Operator HTTP Endpoint
|
|
|
|
|
2016-08-30 20:15:37 +00:00
|
|
|
The Operator endpoint provides cluster-level tools for Consul operators, such
|
2016-08-30 02:09:57 +00:00
|
|
|
as interacting with the Raft subsystem. This was added in Consul 0.7.
|
|
|
|
|
|
|
|
~> Use this interface with extreme caution, as improper use could lead to a Consul
|
|
|
|
outage and even loss of data.
|
|
|
|
|
2016-11-16 09:01:51 +00:00
|
|
|
If ACLs are enabled then a token with operator privileges may be required in
|
2016-08-30 02:09:57 +00:00
|
|
|
order to use this interface. See the [ACL](/docs/internals/acl.html#operator)
|
|
|
|
internals guide for more information.
|
|
|
|
|
|
|
|
See the [Outage Recovery](/docs/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 [`consul operator`](/docs/commands/operator.html)
|
|
|
|
command.
|
|
|
|
|
|
|
|
The following endpoints are supported:
|
|
|
|
|
|
|
|
* [`/v1/operator/raft/configuration`](#raft-configuration): Inspects the Raft configuration
|
|
|
|
* [`/v1/operator/raft/peer`](#raft-peer): Operates on Raft peers
|
2016-11-22 23:24:40 +00:00
|
|
|
* [`/v1/operator/keyring`](#keyring): Operates on gossip keyring
|
2017-02-24 05:00:15 +00:00
|
|
|
* [`/v1/operator/autopilot/configuration`](#autopilot-configuration): Operates on the Autopilot configuration
|
2017-03-01 22:04:40 +00:00
|
|
|
* [`/v1/operator/autopilot/health`](#autopilot-health): Returns the health of the servers
|
2016-08-30 02:09:57 +00:00
|
|
|
|
|
|
|
Not all endpoints support blocking queries and all consistency modes,
|
|
|
|
see details in the sections below.
|
|
|
|
|
|
|
|
The operator endpoints support the use of ACL Tokens. See the
|
|
|
|
[ACL](/docs/internals/acl.html#operator) internals guide for more information.
|
|
|
|
|
|
|
|
### <a name="raft-configuration"></a> /v1/operator/raft/configuration
|
|
|
|
|
|
|
|
The Raft configuration endpoint supports the `GET` method.
|
|
|
|
|
|
|
|
#### GET Method
|
|
|
|
|
2016-08-30 20:15:37 +00:00
|
|
|
When using the `GET` method, the request will be forwarded to the cluster
|
|
|
|
leader to retrieve its latest Raft peer configuration.
|
|
|
|
|
|
|
|
If the cluster doesn't currently have a leader an error will be returned. You
|
2016-11-25 16:00:02 +00:00
|
|
|
can use the `?stale` query parameter to read the Raft configuration from any
|
2016-08-30 20:15:37 +00:00
|
|
|
of the Consul servers.
|
|
|
|
|
|
|
|
By default, the datacenter of the agent is queried; however, the `dc` can be
|
2016-11-25 16:00:02 +00:00
|
|
|
provided using the `?dc=` query parameter.
|
2016-08-30 20:15:37 +00:00
|
|
|
|
|
|
|
If ACLs are enabled, the client will need to supply an ACL Token with
|
|
|
|
[`operator`](/docs/internals/acl.html#operator) read privileges.
|
|
|
|
|
|
|
|
A JSON body is returned that looks like this:
|
|
|
|
|
|
|
|
```javascript
|
|
|
|
{
|
|
|
|
"Servers": [
|
|
|
|
{
|
|
|
|
"ID": "127.0.0.1:8300",
|
|
|
|
"Node": "alice",
|
|
|
|
"Address": "127.0.0.1:8300",
|
|
|
|
"Leader": true,
|
|
|
|
"Voter": true
|
|
|
|
},
|
|
|
|
{
|
|
|
|
"ID": "127.0.0.2:8300",
|
|
|
|
"Node": "bob",
|
|
|
|
"Address": "127.0.0.2:8300",
|
|
|
|
"Leader": false,
|
|
|
|
"Voter": true
|
|
|
|
},
|
|
|
|
{
|
|
|
|
"ID": "127.0.0.3:8300",
|
|
|
|
"Node": "carol",
|
|
|
|
"Address": "127.0.0.3:8300",
|
|
|
|
"Leader": false,
|
|
|
|
"Voter": true
|
|
|
|
}
|
|
|
|
],
|
|
|
|
"Index": 22
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
The `Servers` array has information about the servers in the Raft peer
|
|
|
|
configuration:
|
|
|
|
|
|
|
|
`ID` is the ID of the server. This is the same as the `Address` in Consul 0.7
|
|
|
|
but may be upgraded to a GUID in a future version of Consul.
|
|
|
|
|
|
|
|
`Node` is the node name of the server, as known to Consul, or "(unknown)" if
|
|
|
|
the node is stale and not known.
|
|
|
|
|
|
|
|
`Address` is the IP:port for the server.
|
|
|
|
|
|
|
|
`Leader` is either "true" or "false" depending on the server's role in the
|
|
|
|
Raft configuration.
|
|
|
|
|
|
|
|
`Voter` is "true" or "false", indicating if the server has a vote in the Raft
|
|
|
|
configuration. Future versions of Consul may add support for non-voting servers.
|
|
|
|
|
2016-11-25 16:00:02 +00:00
|
|
|
The `Index` value is the Raft corresponding to this configuration. The latest configuration may not yet be committed if changes are in flight.
|
2016-08-30 20:15:37 +00:00
|
|
|
|
2016-08-30 02:09:57 +00:00
|
|
|
### <a name="raft-peer"></a> /v1/operator/raft/peer
|
|
|
|
|
|
|
|
The Raft peer endpoint supports the `DELETE` method.
|
|
|
|
|
|
|
|
#### DELETE Method
|
|
|
|
|
2016-08-30 20:15:37 +00:00
|
|
|
Using the `DELETE` method, this endpoint will remove the Consul server with
|
|
|
|
given address from the Raft configuration.
|
|
|
|
|
|
|
|
There are rare 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
|
|
|
|
endpoint can be used to remove the failed server so that it is no longer
|
|
|
|
affects the Raft quorum.
|
|
|
|
|
2016-11-25 16:00:02 +00:00
|
|
|
An `?address=` query parameter is required and should be set to the
|
|
|
|
`IP:port` for the server to remove. The port number is usually 8300, unless
|
2016-08-30 20:15:37 +00:00
|
|
|
configured otherwise. Nothing is required in the body of the request.
|
|
|
|
|
|
|
|
By default, the datacenter of the agent is targeted; however, the `dc` can be
|
2016-11-25 16:00:02 +00:00
|
|
|
provided using the `?dc=` query parameter.
|
2016-08-30 20:15:37 +00:00
|
|
|
|
|
|
|
If ACLs are enabled, the client will need to supply an ACL Token with
|
|
|
|
[`operator`](/docs/internals/acl.html#operator) write privileges.
|
|
|
|
|
|
|
|
The return code will indicate success or failure.
|
|
|
|

|
|
|
|
|
2016-11-15 20:33:57 +00:00
|
|
|
#### GET Method
|
|
|
|
|
|
|
|
Using the `GET` method, this endpoint will list the gossip encryption keys
|
|
|
|
installed on both the WAN and LAN rings of every known datacenter. There is more

The `?cas=<index>` can optionally be specified to update the configuration as 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.

If ACLs are enabled, the client will need to supply an ACL Token with
|
|
|
|
[`operator`](/docs/internals/acl.html#operator) write privileges.
|
|
|
|
|
|
|
|
The `PUT` method expects a JSON request body to be submitted. The request
|
|
|
|
body must look like:
|
|
|
|
|
|
|
|
```javascript
|
|
|
|
{

### <a name="autopilot-health"></a> /v1/operator/autopilot/health
|
|
|
|
|
|
|
|
Available in Consul 0.8.0 and later, the autopilot health endpoint supports the
|
|
|
|
`GET` method.
|
|
|
|
|
|
|
|
This endpoint supports the use of ACL tokens using either the `X-CONSUL-TOKEN`
|
|
|
|
header or the `?token=` query parameter.
|
|
|
|
|
|
|
|
By default, the datacenter of the agent is queried; however, the `dc` can be
|
|
|
|
provided using the `?dc=` query parameter.
|
|
|
|
|
|
|
|
#### GET Method
|
|
|
|
|
|
|
|
When using the `GET` method, the request will be forwarded to the cluster
|
|
|
|
leader to retrieve its latest Autopilot configuration.
|
|
|
|
|
|
|
|
If ACLs are enabled, the client will need to supply an ACL Token with
|
|
|
|
[`operator`](/docs/internals/acl.html#operator) read privileges.
|
|
|
|
|
|
|
|
A JSON body is returned that looks like this:
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
`Healthy` is whether all the servers are currently heathly.
|
|
|
|
|
|
|
|
`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).
|
|
|
|
|
|
|
|
The `Servers` list holds detailed health information on each server:
|
|
|
|
|
|
|
|
- `ID` is the Raft ID of the server.
|
|
|
|
|
|
|
|
- `Name` is the node name of the server.
|
|
|
|
|
|
|
|
- `SerfStatus` is the SerfHealth check status for 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.
