# Proxy Defaults Configuration Entry

The `proxy-defaults` configuration entry (`ProxyDefaults` on Kubernetes) allows you to globally configure passthrough Envoy settings for proxies in the service mesh, including both sidecars and gateways.
It is different from the [`mesh` configuration entry](/docs/connect/config-entries/mesh), which sets Consul features for cluster peering, transparent proxy, and TLS behavior that also affect Consul servers.

Only one global entry is supported.
For Consul Enterprise, only the global entry in the `default` partition is recognized.

## Introduction

You can customize some service registration settings for service mesh proxies centrally using the `proxy-defaults` configuration entry in the `kind` field.

You can still override this centralized configuration for specific services
with the [`service-defaults`](/docs/connect/config-entries/service-defaults)
configuration entry `kind` or for individual proxy instances in their [sidecar
service definitions](/docs/connect/registration/sidecar-service).

## Usage

1. Verify that your datacenter meets the conditions specified in the [Requirements](#requirements).
1. Determine the settings you want to implement (see [Configuration](#configuration)). You can create a file containing the configuration or pass them to the state store directly to apply the configuration.
1. Apply the configuration using one of the following methods:
   - Kubernetes CRD: Refer to the [Custom Resource Definitions](/docs/k8s/crds) documentation for details.
   - Issue the `consul config write` command: Refer to the [Consul Config Write](/commands/config/write) documentation for details.

## Configuration

Configure the following parameters to define a `proxy-defaults` configuration entry:

### Prometheus

The following example configures all proxies to expose Prometheus metrics.

<CodeTabs tabs={[ "HCL", "Kubernetes YAML", "JSON" ]}>

```hcl
Kind      = "proxy-defaults"
Name      = "global"
Config {
  envoy_prometheus_bind_addr = "0.0.0.0:9102"
}
```

```yaml
apiVersion: consul.hashicorp.com/v1alpha1
kind: ProxyDefaults
metadata:
  name: global
spec:
  config:
    envoy_prometheus_bind_addr: '0.0.0.0:9102'
```

```json
{
  "Kind": "proxy-defaults",
  "Name": "global",
  "Config": {
    "envoy_prometheus_bind_addr": "0.0.0.0:9102"
  }
}
```

### Access Logs

The following example is a minimal configuration for enabling access logs for all proxies.
Refer to [access logs](/docs/connect/observability/access-logs) for advanced configurations.

<CodeTabs tabs={[ "HCL", "Kubernetes YAML", "JSON" ]}>

```hcl
Kind      = "proxy-defaults"
Name      = "global"
AccessLogs {
  Enabled = true
}
```

```yaml
apiVersion: consul.hashicorp.com/v1alpha1
kind: ProxyDefaults
metadata:
  name: global
spec:
  accessLogs:
    enabled: true
```

```json
{
  "Kind": "proxy-defaults",
  "Name": "global",
  "AccessLogs": {
    "Enabled": true
  }
}
```

### Proxy-specific defaults

The following example configures some custom default values for all proxies.

<CodeTabs tabs={[ "HCL", "Kubernetes YAML", "JSON" ]}>

```hcl
Kind      = "proxy-defaults"
Name      = "global"
Config {
  local_connect_timeout_ms = 1000
  handshake_timeout_ms     = 10000
}
```

```yaml
apiVersion: consul.hashicorp.com/v1alpha1
kind: ProxyDefaults
metadata:
  name: global
spec:
  config:
    local_connect_timeout_ms: 1000
    handshake_timeout_ms: 10000
```

```json
{
  "Kind": "proxy-defaults",
  "Name": "global",
  "Config": {
    "local_connect_timeout_ms": 1000,
    "handshake_timeout_ms": 10000
  }
}
```
