# `sidecar_service` Stanza

<Placement groups={['job', 'group', 'service', 'connect', 'sidecar_service']} />

The `sidecar_service` stanza allows configuring various options for the sidecar
proxy managed by Nomad for [Consul
Connect](/docs/integrations/consul-connect) integration. It is
valid only within the context of a connect stanza.

```hcl
 job "countdash" {
   datacenters = ["dc1"]
   group "api" {
     network {
       mode = "bridge"
     }

     service {
       name = "count-api"
       port = "9001"

       connect {
         sidecar_service {}
       }
     }
     task "web" {
         driver = "docker"
         config {
           image = "test/test:v1"
         }
     }
   }
 }

```

## `sidecar_service` Parameters

- `tags` <code>(array&lt;string&gt;: nil)</code> - Custom Consul service tags for the sidecar service.

- `port` `(string: )` - Port label for sidecar service.

- `proxy` <code>([proxy][]: nil)</code> - This is used to configure the sidecar proxy service.

## `sidecar_service` Examples

The following example is a minimal `sidecar_service` stanza with defaults

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