proxy Stanza

The proxy stanza allows configuring various options for the sidecar proxy managed by Nomad for Consul Connect. It is valid only within the context of a sidecar_service stanza.

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

  group "api" {
    network {
      mode = "bridge"
    }

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

      connect {
        sidecar_service {
          proxy {}
        }
      }
    }

    task "web" {
      driver = "docker"

      config {
        image = "hashicorpnomad/counter-api:v3"
      }
    }
  }
}

proxy Parameters

• local_service_address (string: "127.0.0.1") - The address the local service binds to. Useful to customize in clusters with mixed Connect and non-Connect services.
• local_service_port (int: <varies>) - The port the local service binds to. Usually the same as the parent service's port, it is useful to customize in clusters with mixed Connect and non-Connect services.
• upstreams (upstreams: nil) - Used to configure details of each upstream service that this sidecar proxy communicates with.
• expose (expose: nil) - Used to configure expose path configuration for Envoy. See Consul's Expose Paths Configuration Reference for more information.
• config (map: nil) - Proxy configuration that's opaque to Nomad and passed directly to Consul. See Consul Connect's documentation for details.

proxy Examples

The following example is a proxy specification that includes upstreams configuration.

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