# `upstreams` Stanza

<table class="table table-bordered table-striped">
  <tr>
    <th width="120">Placement</th>
    <td>
      <code>job -> group -> service -> connect -> sidecar_service -> proxy -> **upstreams** </code>
    </td>
  </tr>
</table>

The `upstreams` stanza allows configuring various options for managing upstream
services that a [Consul
Connect](/guides/integrations/consul-connect/index.html) proxy routes to.  It
is valid only within the context of a `proxy` stanza.

For Consul-specific details see the [Consul Connect
Guide](https://learn.hashicorp.com/consul/getting-started/connect#register-a-dependent-service-and-proxy).

```hcl
job "countdash" {
  datacenters = ["dc1"]

  group "dashboard" {
    network {
      mode = "bridge"

      port "http" {
        static = 9002
        to     = 9002
      }
    }

    service {
      name = "count-dashboard"
      port = "9002"

      connect {
        sidecar_service {
          proxy {
            upstreams {
              destination_name = "count-api"
              local_bind_port  = 8080
            }
          }
        }
      }
    }

    task "dashboard" {
      driver = "docker"

      env {
        COUNTING_SERVICE_URL = "http://${NOMAD_UPSTREAM_ADDR_count_api}"
      }

      config {
        image = "hashicorpnomad/counter-dashboard:v1"
      }
    }
  }
}

```

## `upstreams` Parameters

- `destination_name` `(string: <required>)` - Name of the upstream service.
- `local_bind_port` - `(int: <required>)` - The port the proxy will receive
  connections for the upstream on.

The `NOMAD_UPSTREAM_ADDR_<destination_name>` environment variables may be used
to interpolate the upstream's `host:port` address.

Applications are encouraged to connect to `127.0.0.1` and a well defined port
(eg 6379 for Redis) by default. Then when using Consul Connect the application
can be deployed with the Redis upstream's `local_bind_port = 6379` and require
no explicit configuration.

## `upstreams` Examples

The following example is an upstream config with the name of the destination service
and a local bind port.

```hcl
    upstreams {
      destination_name = "count-api"
      local_bind_port = 8080
    }
 ```
