# Network Areas - Operator HTTP API
|
|
|
|
<EnterpriseAlert />
|
|
|
|
The `/operator/area` endpoints provide tools to manage network areas via
|
|
Consul's HTTP API.
|
|
|
|
The network area functionality described here is available only in
|
|
[Consul Enterprise](https://www.hashicorp.com/products/consul/) version 0.8.0 and
|
|
later. Network areas are operator-defined relationships between servers in two
|
|
different Consul datacenters.
|
|
|
|
Unlike Consul's WAN feature, network areas use just the server RPC port for
|
|
communication, and relationships can be made between independent pairs of
|
|
datacenters, so not all servers need to be fully connected. This allows for
|
|
complex topologies among Consul datacenters like hub/spoke and more general
|
|
trees.
|
|
|
|
Please check the [Network Areas tutorial](https://learn.hashicorp.com/tutorials/consul/federation-network-areas) for more details.
|
|
|
|
## Create Network Area
|
|
|
|
This endpoint creates a new network area and returns its ID if it is created
|
|
successfully.
|
|
|
|
| Method | Path | Produces |
|
|
| ------ | ---------------- | ------------------ |
|
|
| `POST` | `/operator/area` | `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:write` |
|
|
|
|
-> The corresponding CLI command is [`consul operator area create`](/commands/operator/area#create).
|
|
|
|
### Parameters
|
|
|
|
- `dc` `(string: "")` - Specifies the datacenter to query. This will default to
|
|
the datacenter of the agent being queried. This is specified as a URL query
|
|
parameter.
|
|
|
|
- `PeerDatacenter` `(string: <required>)` - Specifies the name of the Consul
|
|
datacenter that will be joined the Consul servers in the current datacenter to
|
|
form the area. Only one area is allowed for each possible `PeerDatacenter`,
|
|
and a datacenter cannot form an area with itself.
|
|
|
|
- `RetryJoin` `(array<string>: nil)`- Specifies a list of Consul servers to
|
|
attempt to join. Servers can be given as `IP`, `IP:port`, `hostname`, or
|
|
`hostname:port`. Consul will spawn a background task that tries to
|
|
periodically join the servers in this list and will run until a join succeeds.
|
|
If this list is not supplied, joining can be done with a call to the
|
|
[join endpoint](#join-network-area) once the network area is created.
|
|
|
|
- `UseTLS` `(bool: <optional>)` - Specifies whether gossip over this area should be
|
|
encrypted with TLS if possible.
|
|
|
|

```json
|
|
[
|
|
{
|
|
"ID": "afc5d95c-1eee-4b46-b85b-0efe4c76dd48",
|
|
"Name": "node-2.dc1",
|
|
"Addr": "127.0.0.2",
|
|
"Port": 8300,
|
|
"Datacenter": "dc1",
|
|
"Role": "server",
|
|
"Build": "0.8.0",
|
|
"Protocol": 2,
|
|
"Status": "alive",
|
|
"RTT": 256478
|
|
}
|
|
]
|
|
```
|
|
|
|
- `ID` is the node ID of the server.
|
|
|
|
- `Name` is the node name of the server, with its datacenter appended.
|
|
|
|
- `Addr` is the IP address of the node.
|
|
|
|
- `Port` is the server RPC port of the node.
|
|
|
|
- `Datacenter` is the node's Consul datacenter.
|
|
|
|
- `Role` is always "server" since only Consul servers can participate in network
|
|
areas.
|
|
|
|
- `Build` has the Consul version running on the node.
|
|
|
|
- `Protocol` is the [protocol version](/docs/upgrading#protocol-versions)
|
|
being spoken by the node.
|
|
|
|
- `Status` is the current health status of the node, as determined by the
|
|
network area distributed failure detector. This will be "alive", "leaving",
|
|
"left", or "failed". A "failed" status means that other servers are not able
|
|
to probe this server over its server RPC interface.
|
|
|
|
- `RTT` is an estimated network round trip time from the server answering the
|
|
query to the given server, in nanoseconds. This is computed using [network
|
|
coordinates](/docs/internals/coordinates).
