# Proxy Defaults

-> **v1.8.4+:** On Kubernetes, the `ProxyDefaults` custom resource is supported in Consul versions 1.8.4+.<br />
**v1.5.0+:** On other platforms, this config entry is supported in Consul versions 1.5.0+.

The `proxy-defaults` config entry kind (`ProxyDefaults` on Kubernetes) allows for configuring global config
defaults across all services for Connect proxy configuration. Currently, only
one global entry is supported.

## Sample Config Entries

### Default protocol

Set the default protocol for all sidecar proxies:

<Tabs>
<Tab heading="Consul OSS">

Set the default protocol for all sidecar proxies:

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

```hcl
Kind      = "proxy-defaults"
Name      = "global"
Config {
  protocol = "http"
}
```

```yaml
apiVersion: consul.hashicorp.com/v1alpha1
kind: ProxyDefaults
metadata:
  name: global
spec:
  config:
    protocol: http
```

```json
{
  "Kind": "proxy-defaults",
  "Name": "global",
  "Config": {
    "protocol": "http"
  }
}
```

</CodeTabs>

</Tab>
<Tab heading="Consul Enterprise">

-> **NOTE:** The `proxy-defaults` config entry can only be created in the `default`
namespace and it will configure proxies in **all** namespaces.

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

```hcl
Kind      = "proxy-defaults"
Name      = "global"
Namespace = "default" # Can only be set to "default".
Config {
  protocol = "http"
}
```

```yaml
apiVersion: consul.hashicorp.com/v1alpha1
kind: ProxyDefaults
metadata:
  name: global
  namespace: default
spec:
  config:
    protocol: http
```

```json
{
  "Kind": "proxy-defaults",
  "Name": "global",
  "Namespace": "default",
  "Config": {
    "protocol": "http"
  }
}
```

</CodeTabs>

</Tab>
</Tabs>

### Prometheus

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"
  }
}
```

</CodeTabs>

### Proxy-specific defaults

Set proxy-specific defaults:

<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
  }
}
```
